Since the sweat glands are controlled by the sympathetic nervous system, the assessment of skin conductance skin conductance level and skin conductance response through specific sensors is considered an indicator of psychophysiological activation.

EDA has been used in different studies: from the baseline evaluation of activation levels to the study of emotions and characterization of best performances 14 14 Bertollo M, Bortoli L, Gramaccioni G, Hanin Y, Comani S, Robazza C. Behavioural and psychophysiological correlates of athletic performance: A test of the multi-action plan model.

Appl Psychophysiol Biof ;38 2 In most cases, changes in EDA occur as a set of responses mediated by the autonomic nervous system. Increments of skin conductance level SCL are due to increased activation also related to emotions and anxiety. Stimuli with strong positive or negative affective value or associated with decision making are able to evoke electrodermal responses.

Munro and colleagues 15 15 Munro LL, Dawson ME, Schell AM, Sakai LM. Electrodermal lability and rapid performance decrement in adegraded stimulus continuous performance task.

J Psychophysiol. noticed that SCL increased during the execution of a task and suggested two possible explanations: 1 tasks require a lot of attention resources and this may be associated with a higher activation of the autonomic nervous system; 2 stress and emotions are responsible of the increased SCL rather than attention and effort.

Another useful physiological parameter is respiratory rhythm, usually evaluated through a strain gauge below the chest cage. During task execution, breathing alterations can often be observed.

For example, a superficial respiration involves mainly shoulder muscles and not abdominals; in other cases, the athlete may hold the breath or, conversely, voluntarily increase the respiratory rate. Such variations, also influenced by anxiety and stress, have been associated with poor performances 16 16 Wilson WS, Somers K.

Heart rate variability biofeedback as a strategy for dealing with competitive anxiety: A case study. Surface electroencephalography EEG in the scalp is the mostly used neuro technique in sport setting to record the electrical potentials produced by pyramidal cells.

These measurements are obtained through electrodes placed on the head according to standard systems of positioning. EEG studies showed that specific frequency bands of brain oscillation alpha, beta, theta, etc. are associated with precise mental states calm, arousal, attention, etc.

Indeed, a great deal of research demonstrated an association between particular electroencephalographic patterns and performance in specific cognitive tasks and activities.

For this reason, electroencephalography is used as a high-resolution temporal technique to understand performance and its improvements in the context of sports sciences 18 18 Park JL, Fairweather MM, Donaldson DI. Making the case for mobile cognition: EEG and sports performance. Neurosci Biobehav Rev ; Psychophysiologists generally use a multidimensional and multimodal approach to investigate performance, integrating physiological measurements with behavioral and psychological data.

Measures such as skin conductance or those derived from EEG, EMG and ECG are linked to cognitive processes such as attention and emotional states.

The modulation of physiological parameters can be used to control and increase performance. For example, heart rate increase and decrease has been studied in relation to the cognitive processes involved in motor performance 19 19 Abernethy B, Maxwell JP, Masters RS, Van der Kamp J, Jackson RC.

An external focus of attention was associated with a pronounced heart rate decrease immediately before a task shot , while internal focus was linked to increased heart rate. Better performance was obtained with the use of an external focus, associated with heart rate decrease.

Other authors have also considered HRV indices in relation to cognitive processes. Cooke and colleagues 23 23 Cooke A, Kavussanu M, McIntyre D, Ring C.

Psychological, muscular and kinematic factors mediate performance under pressure. observed how heart rate variability in LF increased under augmented pressure during golf putting. The authors attributed this result to the increase in respiratory volume under pressure. In this case, an increased heart rate variability in HF band is explained by its sensitivity to breathing rhythm changes.

However, researches have not observed any change in HF, despite the increased pressure and perception of greater effort during the task. It seems that the impact of the physical and postural demands of the putting on cardiac measurements, even minimal, is higher compared to that of mental activity.

Mullen and colleagues 25 25 Mullen R, Hardy L, Tattersall A. The effects of anxiety on motor performance: a test of the conscious processing hypothesis.

gave a different explanation of the meaning of HRV. They conducted a study on amateur golfers using a putting task performed with and without a concurrent distracting task.

They found that HF was higher during the putting condition with distracting stimulus and attributed this result to breathing relaxation strategies adopted by participants that affected the high frequency component of HRV.

Regarding EDA, Tremayne and Barry 21 21 Tremayne P, Barry RJ. Electrodermal activity data showed a decrease in the values of expert shooters before the shot; it could reflect a quiet state of the body in the last seconds before the shot, immediately followed by a return to the initial values.

SCL was recently used to identify individual zones of optimal functioning and typify optimal-poor and controlled-automatic performances in the framework of the MAP model. Specifically, an increase of SCL during more controlled performances Type2, Type3 compared to the automatic ones Type1, Type4 was found.

These results suggest the existence of different mechanism of energy regulation and mobilization as related to the different types of performance states; an alternative explanation relies on the concept of attention and stress in a controlled situation, which leads to an increased electrodermal arousal 14 14 Bertollo M, Bortoli L, Gramaccioni G, Hanin Y, Comani S, Robazza C.

Electromiography has been used to evaluate neural activation during fatiguing isometric motor tasks, or different muscular activity related to internal and external focus. In this regard, Zachry and colleagues 26 26 Zachry T, Wulf G, Mercer J, Bezodis N.

Increased movement accuracy and reduced EMG activity as the result of adopting an external focus of attention. Brain Res Bull, ; showed that the accuracy of the throw in basketball players was greater with an external focus toward the basket compared to an internal one toward the arm.

In addition, electromyographic activity of some muscle groups was found to be slower with an external focus compared to an internal one.

This suggests that an external focus could increase the movement economy and reduce the elements in the motor system that impede movement control and impair the outcome. Moreover, neuromuscular data obtained through EMG analysis in a study about motivational cues on performance, interestingly indicated that this kind of stimuli partially blocked the effects of fatigue on the central motor command; indeed, participants that were administered these stimuli were able to sustain or even increase the neural activation of the working muscles during the final moments of a fatiguing isometric motor task 27 27 Bigliassi, M, SilvaVB, KarageorghisCI, BirdJM, SantosPC, Altimari LR.

Brain mechanisms that underlie the effects of motivational audiovisual stimuli on psychophysiological responses during exercise. Regarding the monitoring of brain activity in sport setting, electroencephalography is the most used technique because it can be used also outside the laboratory environment.

Indeed, some types of equipment make possible to collect data even in more ecological settings. This enables researchers to describe optimal pattern of cortical activity during performance in various sports, such as archery, shooting, or golf 11 11 Hatfield BD, Kerick SE.

Electroencephalography in shooting sports allows detecting optimal performance predictors through electroencephalographic differences in pre-shooting conditions between experts and novices, and between optimal and non-optimal performances in the same athlete. This technique allows the study of some brain wave characteristics and frequencies, linking them to specific situations as mentioned before.

In their review chapter on superior sport performance, Hatfield and Kerick 11 11 Hatfield BD, Kerick SE. observed that there was a cortical asymmetry in the temporal area in the alpha band of rifle shooters during a 7. Alpha power showed a noticeable increase over the 7.

These authors interpreted the increase of alpha activity in the left hemisphere as a decreased activation of the same hemisphere. The same authors noticed that the left temporal hemisphere is devoted to language processing and suggested that increased alpha activity might indicate a reduction of the symbolic and verbal activity as well as of self-talk, and an allocation of more resources to the visual-motor stream in the right hemisphere.

This interpretation seems to be congruent with the idea that self-talk can be a potential performance "disturbing" process. An ecological approach to assess differences in skill level and the related mental states is useful to examine the differences between expert and non-expert athletes in a specific task.

Del Percio and colleagues 28 28 Del Percio C, Babiloni C, Bertollo M, Marzano N, Iacoboni M, Infarinato F, et al.

Visuo-attentional and sensorimotor alpha rhythms are related to visuo-motor performance in athletes. Hum Brain Map. found that elite pistol shooters are characterized by an increase in the power of high alpha band Hz and beta band Hz , probably linked to attentional processes.

In a subsequent study, results suggested that elite athletes are characterized by a stabilization in the functional coupling of preparatory waves alpha-beta between the frontal visual-spatial areas and parietal-occipital cortical areas 29 29 Del Percio C, Iacoboni M, Lizio R, Marzano N, Infarinato F, Vecchio F, et al.

Functional coupling of parietal alpha rythms is enhanced in athletes before visuo-motor performance: a coherence electroencephalographic study. Doppelmayr and colleagues 30 30 Doppelmayr M, Finkenzeller T, Sauseng P.

Frontal midline theta in the pre-shot phase of rifle shooting: differences between experts and novices.

The results indicated higher theta wave activity in expert athletes, closely localized in the anterior cingulate area and in the frontal cortex. Experts and non experts use different strategies during the aiming period. Indeed, novices keep a relatively constant amount of attention to the target, while experts are able to increase attention exactly to the time point of the trigger pull.

Electroencephalography was also used to study the influence of motivational audiovisual stimuli, such as music and video, in increasing situational motivation and enhance performance 27 27 Bigliassi, M, SilvaVB, KarageorghisCI, BirdJM, SantosPC, Altimari LR.

Specifically, it was demonstrated that sensory stimuli mediate brain responses to exercise that ameliorate the effects of fatigue and increase situational motivation.

The motivational audiovisual stimuli seemed to modulate the amplitude of theta waves in the frontal cortex and beta waves in the central areas of the brain; the motivational content of the sensory stimulus likely influences the activity of the central motor command by decreasing low-frequency waves and consequently the fatigue, and increasing beta activity and the arousal level.

The effects of the motivational stimuli on the central regions of the cortex are probably linked to the protective mechanisms of motivation on exercise engagement; in particular, motivational stimuli partially obstacle the negative effects of fatigue on psychophysiological responses and exercise performance.

More recently, Cheron and colleagues have described in depth the meaning of the oscillatory brain rhythms hypothesizing some specific EEG biomarkers 31 31 Cheron G, Petit G, Cheron J, Leroy A, Cebolla A, Cevallos C, et al.

Brain oscillations in sport: toward EEG biomarkers of performance. Front psychol. Theta oscillation, for instance, plays an important function in motor control.

It was also demonstrated that the theta power increase in the controlateral motor area during the onset of fast ballistic movements 31 31 Cheron G, Petit G, Cheron J, Leroy A, Cebolla A, Cevallos C, et al. Moreover, theta oscillation was related with the onset of the movement and the theta power correlated with movement acceleration 31 31 Cheron G, Petit G, Cheron J, Leroy A, Cebolla A, Cevallos C, et al.

Other studies showed an association between different stages of exercising and modulations of the alpha rhythm. Despite contrasting results, it was shown that the shift from rest to exercise is linked to an increase in alpha band, while brain activity during and after exercise has been associated with both upward 32 32 Gutmann B, Mierau A, Hülsdünker T, Hildebrand C, Przyklenk A, Hollmann W, et al.

Effects of physical exercise on individual resting state EEG alpha peak frequency. Neural plast. and downward variations 31 31 Cheron G, Petit G, Cheron J, Leroy A, Cebolla A, Cevallos C, et al. This rhythm was also studied as a marker of resources allocation during motor programming 33 33 Cooke A, Gallicchio G, Kavussanu M, Willoughby A, McIntyre D, Ring C.

Beta oscillation Hz ,on the other hand, has a central position in the treatment of sensorimotor information and serves as a functional link between different brain regions such as the pre-motor, motor M1 , and somatosensory S1 cortex, the supplementary motor area, and the cerebellum 32 32 Gutmann B, Mierau A, Hülsdünker T, Hildebrand C, Przyklenk A, Hollmann W, et al.

Current advances in EEG signal processing and modifications of the hardware led to EEG recordings while individuals behave naturally, like walking outdoors. It has also been demonstrated that wireless EEG can be used to collect data in a simulated working situation involving complex motor actions or in a cooperative motor task 34 34 Filho E, Bertollo M, Tamburro G, Schinaia L, Chatel-Goldman J, di Fronso S.

et al. Hyperbrain features of team mental models within a juggling paradigm: a proof of concept. Moreover, highly portable new EEG systems with dry and wet electrodes could lead to major progresses in brain computer interfaces and neurofeedback protocols.

In order to test whether specific affective, psychophysiological, and postural trends could typify performance states as conceptualized in the MAP model, Bertollo and colleagues conducted a single-subject study on pistol shooting and dart throwing 14 14 Bertollo M, Bortoli L, Gramaccioni G, Hanin Y, Comani S, Robazza C.

The shooter involved in the study showed lower levels of SCL in Type 1 performance compared to Type 2 and Type 3, and similar levels in Type1 and Type 4. A similar pattern also emerged in the dart throwing participant. SCL can be considered one of the best indicators of the arousal-activation binomial in these precision sports.

A higher electrodermal activity in Type 2 and Type 3 performance states compared to Type 1 and Type 4 suggested the existence of different mechanisms of energy mobilization and regulation, and a related increased autonomic nervous system activation.

No differences were observed on HR among the four types of performances likely because of fatigue that caused a generalized HR increase. The decrease in respiratory rate found in Type 3 performance suggested that the respiration process can be influenced by fatigue due to the attentional control exerted during execution.

All these interpretations have potential practical implications. Coaches could monitor psychophysiological states of athlete, help them identify individualized performance optimization strategies, and use biofeedback techniques to improve self-regulation and monitor individual levels of arousal-activation.

The MAP model assumptions were also tested in motor sport and among professional racecar drivers. Filho and colleagues 6 6 Filho E, di Fronso S, Mazzoni C, Robazza C, Bortoli L, Bertollo M. analyzed the kinematic and psychophysiological mechanism of braking modulation and acceleration dynamics.

Findings supported the notion that different psychophysiological states underlie the different MAP model categories. From an applied point of view, given that most drivers showed unique heart rate and respiratory rate patterns linked to Type 1 performance, a heart rate variability training may increase the probability of peak performance experiences.

These results are in accordance with the principle of individualization in athletic training and reinforce the importance of idiosyncratic studies and applications in sport psychology, especially among skilled athletes.

Results also underlie the importance of developing idiosyncratic and multimodal plans, including bio-neurofeedback training, for performance optimization. Findings in an Olympic shooting athlete 7 7 di Fronso S, Robazza C, Filho E, Bortoli L, Comani S, Bertollo M.

further supported the MAP model tenets. Optimal-automatic Type 1 and suboptimal-controlled Type 3 states were indeed typified by distinct neural activity patterns. Specifically, EEG analysis showed a synchronization pattern in Type 1 performance in agreement with the neural efficiency hypothesis i.

A task-relevant focus on the core components of the action can allow the athlete to regain an optimal performance state. Findings can inform neurofeedback training for performance enhancement.

Results can also help the identification of the cortical areas where to apply transcranial stimulation methods 35 35 Paulus W. Transcranial electrical stimulation tES-tDCS; tRNS, tACS methods. Neuropsychol rehab. to facilitate cortical plasticity.

The MAP model predictions were also examined in a single-subject study using a cycling task 36 36 Comani S, di Fronso S, Castronovo AM, Schmid M, Bortoli L, Conforto S, et al.

Attentional focus and functional connectivity in cycling: An EEG case study. In XIII Mediterranean Conference on Medical and Biological Engineering and Computing Springer, Cham. Cortical functional connectivity was assessed through EEG coherence analysis, which has been extensively used to study the neural mechanisms underlying perceptive, cognitive e.

Overall, results indicated specific functional connectivity patterns to be associated with different attention strategies; for instance, an extensive communication among areas was found in a Type 1 performance state prompted by an external associative strategy i.

Findings support the hypothesis that specific strategies may stimulate flow experiences characterized by specific electrophysiological patterns leading to better performance.

An important purpose of the psychophysiological monitoring is the use of bodily signals as a reliable feedback to help athletes improve their awareness of bodily functions and develop self-regulation skills.

Through brain-body computer interface, biofeedback BFB and neurofeedback NFB systems display information that individuals can use to self-regulate brain-body processes in real time.

Moreover, multiple types of signals can be integrated, thus advancing the understanding of complex performance factors and self-regulation systems.

Top 5 Foods to Increase Athletic Performance

Athletic performance optimization -

Peak performance is an umbrella term used to classify positive states surrounding performance 1 1 KimiecikJC, JacksonSA. Optimal experience in sport: A flow perspective.

In: advances in sport psychology. Champaign, IL. Human Kinetics, Improving and reaching optimal performance during training and competition is one of the main goal for coaches and athletes.

Unfortunately, optimal psychophysiological and psychosocial states do not occur frequently; competitive pressure can disrupt task execution and dysfunctional unpleasant states can appear.

We strongly advocate the development and adoption of idiosyncratic approaches for performance enhancement. Individualized strategies are also a main focus of the individual zones of optimal functioning IZOF model in which pleasant and unpleasant emotional states can exert beneficial, detrimental, or both effects on performance, depending on their individual meaning and intensity 3 3 Robazza, C.

This model, in particular, places emphasis on the interaction between performance level and attentional control level during task execution. This 2×2interaction i. Type 2 performance is typified by a higher level of attentional focus and functional performance.

Compensatory resources need to be recruited for this performance state that can be obtained by consciously focusing attention on the core components of the action, such as pedaling rate in cycling 5 5 Bertollo M, di Fronso S, Filho E, Lamberti V, Ripari P, Reis VM, et al.

Type 3 suboptimal performance is characterized by an excessive attention focus that leads to over-controlled task execution, movement disruption, and dysfunctional performance. Type 4 performance is characterized by lack or task-irrelevant attentional focus and dysfunctional performance.

Paying attention to the core components of the action should help the athlete to recover from suboptimal performance states.

Moreover, an appropriate focus on the core components should facilitate the switch on a less consciously controlled and more automatic task execution, and increase flow experiences. A comprehensive assessment of performers implies the knowledge not only of those strategies to reach and maintain good performance i.

The study of human behavior in a holistic perspective, based on the assumption that measuring the processes of body-mind interaction can shed light on the human mind 9 9 Cacioppo,JT, TassinaryLG, Berntson,G, editors.

Handbook of psychophysiology. University Press, Psychophysiology is not devoted to a better knowledge of isolated components of the body, but rather it is addressed to gain insight on the functioning of the entire organism e. Mechanisms of mind-body interaction and optimal performance.

Front Psychol. The psychophysiological monitoring consists in the assessment of the activation and functioning level of the body. In sport, it can be used to better understand the underlying processes of performance and to subsequently increase or optimize it 11 11 Hatfield BD, Kerick SE. The psychology of superior sport performance.

In: Handbook of sport psychology. Hoboken NJ : Wiley, Techniques used for this type of monitoring include, for example, electromyography EMG , electrocardiography ECG , electroencephalography EEG , as well as other simple techniques to measure electrodermal activity EDA or respiratory rhythm.

Electromyography EMG is a technique to analyze muscular signals generated by physiological changes in the state of the muscle membranes.

Surface electrodes are mainly used for the study of neuromuscular activation in postural tasks, functional movements, working conditions, or workout. The analysis of these types of data provides useful information to improve performance in motor and sport activities.

From a psychophysiological point of view, muscle tension has often been associated with emotional experience, and there are some target muscles, such as trapezium, which are often monitored for information about the level of anxiety and general tension of the athlete.

Electrocardiography ECG measures heart electrical signal and provides parameters such as Heart Rate HR or Heart Rate Variability HRV; i. In order to simplify the use of these measures, a pletismograph is placed on the finger of a hand instead of traditionally connect electrodes to the chest.

In this way, blood flow variations in the finger capillaries, that faithfully represent the heartbeat, are recorded. Nowadays, chest strains wireless data assessed with the use of a computer are also used to monitor heart rate. Heart rate variability may vary in response to factors such as breathing rhythm, emotional states, anxiety and stress.

Linear analysis of HRV provide indices considered expression of sympathetic and parasympathetic activity and of the balance between these two branches of autonomic nervous system 9 9 Cacioppo,JT, TassinaryLG, Berntson,G, editors.

Examples of these indices in the frequency domain are: Very Low Frequency VLF , usually associated with temperature regulation; Low Frequency LF , usually associated with blood pressure regulation; High frequency HF , associated with respiratory influences.

The ability of the body to modify its balance toward one or the other activity sympathetic or parasympathetic is very important for a good cardiac functioning and is a mechanism that tends to a dynamic balance.

High HRV is associated with good heart health and best sports performance, while periods of mental stress can reduce it 12 12 Wilson VE, Somers K. Psychophysiological assessment and training with athletes: Knowing and managing your mind and body. Heart rate variability can be attributed to changes in parasympathetic control associated with breathing and can be used as a vagal-heart rate index.

In detail, HF linked to respiratory frequency reflects variations in the vagal control and is thus used as a parasympathetic activity index. In the field of sport psychophysiology, there is a great interest in HRV as it relates to arousal: HF increases, indeed, under high stress and anxiety conditions, especially with focused attention and motor inhibition.

Other kind of linear and non-linear HRV-related indices e. Heart Rate Variability Discriminates Competitive Levels in Professional Soccer Players. Electrodermal activity EDA represents the electrical conductance that can vary according to the skin sweating level.

gave a different explanation of the meaning of HRV. They conducted a study on amateur golfers using a putting task performed with and without a concurrent distracting task.

They found that HF was higher during the putting condition with distracting stimulus and attributed this result to breathing relaxation strategies adopted by participants that affected the high frequency component of HRV. Regarding EDA, Tremayne and Barry 21 21 Tremayne P, Barry RJ.

Electrodermal activity data showed a decrease in the values of expert shooters before the shot; it could reflect a quiet state of the body in the last seconds before the shot, immediately followed by a return to the initial values. SCL was recently used to identify individual zones of optimal functioning and typify optimal-poor and controlled-automatic performances in the framework of the MAP model.

Specifically, an increase of SCL during more controlled performances Type2, Type3 compared to the automatic ones Type1, Type4 was found. These results suggest the existence of different mechanism of energy regulation and mobilization as related to the different types of performance states; an alternative explanation relies on the concept of attention and stress in a controlled situation, which leads to an increased electrodermal arousal 14 14 Bertollo M, Bortoli L, Gramaccioni G, Hanin Y, Comani S, Robazza C.

Electromiography has been used to evaluate neural activation during fatiguing isometric motor tasks, or different muscular activity related to internal and external focus. In this regard, Zachry and colleagues 26 26 Zachry T, Wulf G, Mercer J, Bezodis N. Increased movement accuracy and reduced EMG activity as the result of adopting an external focus of attention.

Brain Res Bull, ; showed that the accuracy of the throw in basketball players was greater with an external focus toward the basket compared to an internal one toward the arm. In addition, electromyographic activity of some muscle groups was found to be slower with an external focus compared to an internal one.

This suggests that an external focus could increase the movement economy and reduce the elements in the motor system that impede movement control and impair the outcome. Moreover, neuromuscular data obtained through EMG analysis in a study about motivational cues on performance, interestingly indicated that this kind of stimuli partially blocked the effects of fatigue on the central motor command; indeed, participants that were administered these stimuli were able to sustain or even increase the neural activation of the working muscles during the final moments of a fatiguing isometric motor task 27 27 Bigliassi, M, SilvaVB, KarageorghisCI, BirdJM, SantosPC, Altimari LR.

Brain mechanisms that underlie the effects of motivational audiovisual stimuli on psychophysiological responses during exercise. Regarding the monitoring of brain activity in sport setting, electroencephalography is the most used technique because it can be used also outside the laboratory environment.

Indeed, some types of equipment make possible to collect data even in more ecological settings. This enables researchers to describe optimal pattern of cortical activity during performance in various sports, such as archery, shooting, or golf 11 11 Hatfield BD, Kerick SE. Electroencephalography in shooting sports allows detecting optimal performance predictors through electroencephalographic differences in pre-shooting conditions between experts and novices, and between optimal and non-optimal performances in the same athlete.

This technique allows the study of some brain wave characteristics and frequencies, linking them to specific situations as mentioned before. In their review chapter on superior sport performance, Hatfield and Kerick 11 11 Hatfield BD, Kerick SE. observed that there was a cortical asymmetry in the temporal area in the alpha band of rifle shooters during a 7.

Alpha power showed a noticeable increase over the 7. These authors interpreted the increase of alpha activity in the left hemisphere as a decreased activation of the same hemisphere. The same authors noticed that the left temporal hemisphere is devoted to language processing and suggested that increased alpha activity might indicate a reduction of the symbolic and verbal activity as well as of self-talk, and an allocation of more resources to the visual-motor stream in the right hemisphere.

This interpretation seems to be congruent with the idea that self-talk can be a potential performance "disturbing" process. An ecological approach to assess differences in skill level and the related mental states is useful to examine the differences between expert and non-expert athletes in a specific task.

Del Percio and colleagues 28 28 Del Percio C, Babiloni C, Bertollo M, Marzano N, Iacoboni M, Infarinato F, et al. Visuo-attentional and sensorimotor alpha rhythms are related to visuo-motor performance in athletes. Hum Brain Map.

found that elite pistol shooters are characterized by an increase in the power of high alpha band Hz and beta band Hz , probably linked to attentional processes. In a subsequent study, results suggested that elite athletes are characterized by a stabilization in the functional coupling of preparatory waves alpha-beta between the frontal visual-spatial areas and parietal-occipital cortical areas 29 29 Del Percio C, Iacoboni M, Lizio R, Marzano N, Infarinato F, Vecchio F, et al.

Functional coupling of parietal alpha rythms is enhanced in athletes before visuo-motor performance: a coherence electroencephalographic study. This data is incredibly useful for not only marathon runners, but for all athletes. Alyson was incredible and the process was easy. The process took a couple of hours but completely worth it.

Now I know where I am and the things I need to focus on to be successful for my race. There is no guessing, the science proves it.

Look forward to working with Alyson over the next few months to devise strategies that will improve my overall performance! I am training for IRONMAN and did a run test with her and the amount of knowledge that she has is unbelievable!

To parallel her knowledge is how personable and attentive she is with you! I am someone who asks multiple questions all the time and she always has the right answer and spends time making sure I understand.

In the couple of hours we spent together not only did I learn so much about strategy and preparation but I had immediate feedback on ways to enhance my training and in particular, after that session, running. Due to testing and corrections, I was able to sustain a quicker pace and shave over 20 seconds off my average mile for over 6 miles.

I know under her direction and tutelage my dreams to accomplish and complete an IRONMAN will become more and more a reality. Alyson is simply THE BEST!! Fast-track your athletic performance and optimize your abilities with expert guidance.
