The Sport-specificc common body Sport-specificc measuring methods cmposition. It is important that coaches, trainers, and athletes understand composirion relationship between body composition Sport-specific body composition performance.
On top of that, these measuring methods should be consistent, easily accessible, and reliable. This helps sports nutritionists develop dietary interventions, and athletic trainers create, evaluate, and customize training programs for individual needs.
Not only does this optimize performance, but it can also record sudden changes in body composition that may be a signal of different health concerns.
This is especially important for at-risk athletes with extremely low body fat. As an example, for women athletes this could lead to a phenomenon called the female athlete triadwhich refers to low energy availability or disordered eatingmenstrual dysfunctionand low bone density, resulting in a heightened risk of injuries.
These problems are especially apparent in aesthetic sports and weight class sports where low body fat and extreme dieting are all too common. For safety and ethical reasons, body composition measurements should only be implemented when the athlete is fully grown.
Furthermore, these measurements should be used with caution and the results need to be shared as sensitively as possible. Choosing the wrong words may only increase the chances of unhealthy eating habits and unhealthy body image, which can even lead to eating disorders. The most effective way to have an impact on your body composition is through a well-balanced diet.
Your body composition is a result of several different physiological factors. These include genetics, sex, age, training background, and even your diet. Not only do these determine your body type, but they can also have a significant impact on your physical performance.
Genetic factors have a significant impact on your body composition. After all, your biological makeup determines your height, weight, how naturally lean you are, your tendency to store fat, as well as where the fat is stored. This can further be broken down into other individual physical traits.
The body type is also highly heritable. This may be partly due to having a higher proportion of fast-twitch muscle fibers type II which are not only more suited for higher force production, but also larger in size. This may give some athletes a more muscular appearance.
This is aided by having a higher proportion of endurance-oriented slow-twitch muscle fibers type I. Modern genetics have also identified specific genes that may affect both body composition and performance. One of these is a so-called ACE gene that is associated with better endurance capability.
Another example of this is an ACTN3 gene that is only found in fast-twitch muscle fibers and used during explosive exercises. It is said to have a specific variant that may have a performance effect on elite-level performance.
Conversely, there is also an FTO gene that is closely related to weight gain and obesity. Your sex also has a significant impact on body composition, especially when it comes to body fat.
The reason for this is that women tend to naturally carry more fat due to reproductive reasons — a higher amount of body fat helps prepare for pregnancy and nursing. These physical changes often appear during and after puberty. Interestingly, there seems to be more variability among women whether they carry subcutaneous fat under the skin around the hips and thighs or in the upper body.
On the other hand, men usually have more fat around the trunk and the abdomen visceral fatwhich is proven to have a more negative impact on health. Gender-specific hormones also have a slight impact on body type.
For example, female hormones like estrogen and progesterone also affect water retention during different times of the month. However, it is also important that these changes are taken into account when comparing data between measurements.
In addition to sex hormones, thyroid hormones also play an important role in energy balance energy homeostasis and heat production thermogenesisleading to possible changes in body composition.
Fat percentage and fat accumulation are not the only gender-specific factors that can affect your body composition. For example, women tend to also have less lean muscle mass than men of the same BMI. One reason behind this is that males have times more testosterone in the body. Since it is an anabolic male sex hormone boosts growth produced in the testicles, men tend to accumulate more muscle mass, especially during puberty.
As your metabolism slows down as you grow older, your body composition will naturally go through some physiological changes. One of these is an age-related loss of lean muscle mass, function, and quality known as sarcopenia. Typically sarcopenia speeds up around the age of 75, but can also start sooner or later.
Of course, this is heavily related to your level of activity and diet. This can slow down your metabolism even further.
On a positive note, these effects can be prevented or even reversed with well-planned weight training and the right diet. Another thing to keep in mind is that bone density tends to naturally decline as you age.
Additionally, lower levels of testosterone in men and decreased levels of estrogen in women during menopause are both significant causes of bone loss. As the bones lose their mineral density, they also become more frail, making them more prone to fractures. The ideal body composition depends on your sport and playing position.
Aside from genetic factors and diet, it is well known that body composition changes due to physical activity, making it one of the major components of fitness and overall health.
This means that athletes relying on strengthfaster force production and speed are often more muscular than endurance athletes. While consistent exercise shapes your body to fit your personal physical needs, the same goes for inactive individuals as well. A sedentary lifestyle accelerates weight gain and may cause obesity.
Strength and power athletes often have more lean muscle mass to provide a stronger contraction during sports-specific exercises. However, this comes with a cost. Studies have shown that a higher body mass, regardless of the cause, has a negative effect on maximal oxygen uptake VO 2 max and endurance performance.
This is especially important to remember if you participate in aerobic-anaerobic sports that require endurance as well as high levels of strength.
Soccer being a prime example. Endurance athletes are often built leaner, with better aerobic capacity highest amount of oxygen used during a maximal performance. This means that you use less energy with each step or repetition, making every movement more efficient in the long run.
More intense activities also improve your speed enduranceanaerobic capacity total amount of energy from non-oxygen energy systemand lactate buffering, making sure you perform better during longer exercises with a high heart-rate.
However, higher intensity and higher resistance training will eventually also increase muscle mass — which may not be what your performance needs.
While your age, sex, and training background have some clear effects on your body composition, none of them affects it more than your diet. This is largely due to energy balance which leads to either storing energy as fat or maintaining a balance between food intake and energy usage.
After all, eating more energy than you use leads to gaining weight, and vice versa. Understanding the relationship between individual energy need and energy usage is the key to ideal body composition.

Being heavier, men should have a more difficult time performing consecutive pull-ups. However, because men typically possess more upper-body lean mass, they have more relevant, functional mass to devote to pull-ups. Even when normalizing for body mass and lean mass i. Women only equaled men when the load was perfectly equated i. There were nearly three times as many younger participants as those who were older than age 35 years. Despite this year range, appreciable changes to physiology, particularly in physically-active, resistance-trained adults, are less common than they are with similarly aged, sedentary adults McGregor et al. Thus, for the time being, these findings should be viewed as preliminary. Meanwhile, no differences were seen among the lower percentile groups or with any measure of bone health. The size, architecture, and quality of skeletal muscle reflect its ability to produce force Lieber and Fridén, ; Stock et al. The mass and density of bone are also thought to contribute to force production by providing a stable structure through which force may transfer and elicit human movement. However, there is less evidence available documenting an advantage from exercise-induced gains in bone size Schipilow et al. Interestingly, PBF measures were only relevant to those ranking within the interquartile range i. Together, these could prolong the onset of fatigue and better facilitate sustained movement during extended-duration exercise. For the lowest-ranking participants in this study, the need to improve lean mass appears to supersede all other needs physiological and technical. Their average times ranged between 7. Within the context of this workout, being unable to lift the assigned thruster load for multiple repetitions, or perform pull-ups sequentially, would seem to be the most likely explanations. Meanwhile, the highest-ranked individuals, who also possessed the healthiest body composition, may have reached a point where continued focus on PBF reduction was either unnecessary or unhealthy. Instead, continuing to improve lean mass to further force production capabilities, and possibly perfecting technique may prove more beneficial. Despite the compositional differences seen between men and women, relationships to performance were similar for each sex. A more deliberate effort in recruiting sufficient participants within each competitive class will help to clarify this disagreement. Including assessments of muscular strength in the thruster exercise and maximal pull-up repetitions using all relevant styles would have helped to better explain the practical importance of NBLM to performance. Nevertheless, this appears to be the first study to examine the influence of competition class and percentile rank on relationships between any physiological measure and HIFT performance. Though the reasons for this are unknown, it may imply a greater reliance on movement efficiency rather than strength to complete workout tasks. Still, it may be prudent to assume that this was the consequence of reduced power. By improving NBLM, strength is presumably increased, and this would reduce the relative intensity of the fixed loads prescribed for this workout. Meanwhile, attention to PBF and fat mass reduction only appears to be relevant for moderately ranked individuals. More skilled participants possessed the healthiest fat-to-lean mass ratio, and this seems to suggest that a threshold exists where continued focus on this goal has no additional benefit. This may reflect a need to improve strength, technique, pacing strategy, or possibly all three. Any concerted effort to reduce fat mass at this stage seems to be premature.

Many elite athletes can easily fit into recommended ranges for their sport, but lifestyle habits are not optimized. Others may fall into the extremes, either over or under the typical ranges for their sport. Regardless, developing optimal fueling, training, rest and recovery habits should be priorities for all student-athletes, in order to optimize performance and long-term health. Many student-athletes have goals of gaining or losing weight. Some perceive direct performance benefits, some have aesthetic reasons while others are meeting the necessary weight requirements of their sport e. wrestling and rowing. Student-athletes benefit from focusing on altering body composition more than just weight alone. Losing body fat while maintaining or increasing FFM is typically favorable in sports. When the focus is limited to scale weight, improper fueling becomes more likely as does the risk of losing lean tissue, bone mass or energy stores and gaining undesirable fat stores. Improper fueling can relate to increased illness and injury risk, poor recovery, decreased performance and more. This should always be accompanied by education and counseling that different body types exist and succeed in different sports and that it is impossible to make a one-size-fits-all recommendation. Performed best? What would reflect a realistic rate of change? Student-athletes may be familiar with the recommended healthy body fat range for adult males percent and females percent. As noted, different healthy ranges suit different individuals and lower or even higher could be appropriate for student-athletes, but these numbers may serve as valuable reference points. It is important to keep in mind that these values are based on skinfold caliper analysis; they are not applicable to other testing methods DEXA, Bod Pod, etc. which yield different results. Student-athletes should avoid extremely low body fat, which can be associated with impaired physiological function in both males and females 2. It is commonly suggested that 5 percent body fat for men and 12 percent for women are the minimum required for healthy endocrine and immune function. The International Society for the Advancement of Kinanthropometry suggests a minimum of sum of 7 skinfolds of mm for men and mm for women. A student-athlete with a higher body fat who drops a significant amount in a short time is at the same risk. Table 1 shows body composition ranges typical for collegiate student-athletes, based on skinfold caliper analysis. These values should not be taken as recommendations or strict guidelines. Rather, they should be used as a reference point when evaluating body composition results. Every student-athlete is different and the recommended range for any specific individual may or may not fall within the range. Table 2 shows compiled bod pod results from the to NFL combine. Note the variability of body composition by position played and also within each category. For example, running backs averaged As a greater rate of obesity, disordered eating and associated health problems are seen at the collegiate level, appropriate attention must also be paid to interventions for student-athletes above and below their target body composition range. Working with a registered dietitian, particularly a board certified specialist in sports dietetics CSSD to design a nutrition plan is recommended. There are many different methods for evaluating body composition. There is no gold standard since some degree of estimation and error is associated with all methods.

Written by: Michelle Rockwell, MS, RD, CSSD, Virginia Polytechnic Institute and State University Body composition is a physical measurement that provides more specific information about body make-up than body weight alone. Does body composition impact athletic performance and health? Assessing body composition There are many different methods for evaluating body composition.
Assessment tools and methods used with college student-athletes: In the collegiate setting, numerous assessment tools are used. Considerations about body composition analysis: A body composition measurement from one method cannot be compared to one from another. For example, a football player evaluated by DEXA at his university cannot compare results to the BodPod values he receives at the NFL combine.
Likewise, when tester or equipment variation comes into play, results also cannot be compared. A cross country runner who has skinfold caliper measurements performed by her strength and conditioning coach cannot compare results to the same measurements taken by the sports dietitian.
Measuring via the same method in a systematic way offers the most benefit for individuals and team analysis. Measurements should be done in private. Results should be handled with sensitivity. The National Athletic Trainers Association suggests that body composition results be treated the same as other medical information with regard to confidentiality.
Measurements should be taken when student-athletes are well-hydrated and before exercise. In general, measurements should be taken no more frequently than every two to three months. Some professionals recommend twice per year or less. Defer to your sports dietitian regarding specific student-athlete protocols.
There should always be a purpose for taking measurement. Clear and consistent communication is paramount. Testers must be sensitive to the impact of assessment on student-athletes. If resources are not available to assist with the management of body composition information and education, its best to avoid it altogether.
Communicating about body composition Always emphasize performance measures, overall training, diet and healthy lifestyle as highest priority for athletes. When body composition change is appropriate, establish a percent body fat range rather than an absolute value.
Changes in body composition should be gradual and targeted changes are priority in the off-season whenever possible. Guide student-athletes to focus on FFM as much as they focus on percent body fat as this is functional, powerful athletic tissue they wish to maintain or increase and can feel more positive than focusing on decreasing percent body fat.
It is recommended that athletics departments develop guidelines and protocol for measurement, analysis and communication of body composition data.

This includes advantageous changes in body composition for health and performance. Why is body composition important? Because not all weight is equal in terms of tissue composition and distribution.
