European BCAA for strength training of Applied Physiology, [online] 5pp. Nutritional supplements such as branched-chain amino acids BCAA; valine, leucine, isoleucine may augment or stimulate skeletal muscle regeneration by suppressing post-exercise protein degradation, therefore leading to greater gains in lean mass [ 5 ].

BCAA for strength training -

The preservation of lean mass is important for both athletic populations striving to improve athletic performance, and for older or sedentary populations at risk for obesity-related or age-onset obesity or sarcopenia and other age-related diseases [ 4 , 6 , 16 ]. Providing individuals with BCAA can stimulate myofibrillar protein synthesis and in turn preserve lean body mass.

Our data suggests that BCAA supplementation may be effective in individuals attempting to lose fat mass while maintaining lean mass. There is a paucity of studies investigating the use of BCAAs with a hypocaloric diet and resistance training, but some studies attempt to elucidate the connection between some aforementioned factors.

In a study investigating a hypocaloric diet in conjunction with increased dietary protein intake, Mettler et al. However, these researchers sourced protein intake from dietary foods, rather than a supplement such as BCAA.

Coker et al. Researchers illustrated that the combination of a protein supplement whey and essential amino acids with a calorie restricted diet was more effective than a hypocaloric meal replacement control at concurrently reducing adipose tissue and preserving lean tissue during the caloric restriction-induced weight loss in elderly obese subjects [ 2 ].

Similarly, BCAA supplementation was found to provide a beneficial effect on body composition and isometric hand-grip strength, even without a concurrent exercise training protocol [ 28 ]. Researchers demonstrated that 30 days of ingesting 14 g of a BCAA supplement significantly lean mass and hand-grip strength in untrained males.

However, no control group was provided for this study, making the conclusions as to whether the BCAA supplementation was predominant in improving lean mass and grip strength inconclusive [ 28 ]. Eight weeks of resistance training combined with a BCAA supplement and caloric restriction elicited a significant difference in RMR between BCAA and CHO groups, where the BCAA group decreased RMR and the CHO group showed no changes.

The amount of lean tissue mass is essential in determining metabolic rate, where a greater amount of lean tissue increases RMR. Lean tissue is more metabolically active than fat tissue, and requires more energy at rest; thus increased energy expenditure can then decrease risk for chronic diseases such as metabolic disease, diabetes mellitus, and cardiovascular disease [ 6 ].

Therefore, the insignificant increase in lean mass in the BCAA group would not contribute to a significant change in RMR. Similarly, Tsujimoto et al. However, a recent study by Spillane et al.

Muscle strength increased with training, but no significant effects were evident between placebo and BCAA groups, indicating the lack of a treatment effect in the BCAA group. The results of this study suggest that there may be a dose—response relationship influencing the effectiveness of a BCAA supplement, where a greater dosage of BCAA induces greater performance benefits [ 29 ].

It is unlikely that the training duration of this study influenced results, as Tsujimoto et al. Further, it may be that in a hypocaloric state the BCAA has a more robust effect [ 30 ].

It is difficult to explain the increase in repetitions to fatigue on the parallel squat in the CHO group, with no other changes being observed within or across groups. It was anticipated that on a hypocaloric diet, there would not be any gains in muscular endurance, given the glycolytic nature of the activity [ 30 , 31 ].

It is possible that the CHO supplementation in the CHO group enhanced glycogen storage, which improved fatigue resistance and in turn resulted in increased repetitions to fatigue. However, our small sample size allows for robust changes in a few subjects to result in significant group improvements.

We observed consistent and nearly uniform responses from subjects across the other measures of muscular performance, but in the repetitions to fatigue a couple subjects showed tremendous improvements, thus resulting in a significant group change.

Additionally, with human performance testing it is possible these subjects did not perform to their maximal ability during pre-testing data collection for a variety of reasons fatigue, distraction, lack of effort, etc. Though there remains controversy regarding the effectiveness of BCAA supplementation on muscle performance and body composition among both trained and untrained persons, there is a greater amount of consensus regarding the effects of BCAA supplements on muscle damage and recovery, which may in turn inform muscle performance strength and endurance.

This in turn may have implications in improved muscle performance and recovery. However Ra et al. The variability in experimental approaches adopted by researchers, and the factors investigated, such as the supplement quantity, treatment duration, timing of ingestion, training status and intensity, and dietary control, make direct comparisons of studies difficult.

It is thus difficult to conclusively quantify the benefits of BCAA supplements across populations. However, our data suggest that under hypocaloric conditions, those who participate in heavy resistance training can maintain lean mass and muscular performance by utilizing a BCAA product pre and post workout.

Further, while this protocol resulted in a loss of lean mass in the CHO group, the improvement in lower body strength and repetitions to fatigue suggest that minimal CHO supplementation on a cut diet may help to maintain some performance measures.

Conclusion These results show that BCAA supplementation in trained individuals performing resistance training while on a hypocaloric diet can maintain lean mass and preserve skeletal muscle performance while losing fat mass.

Background The prevalence of age and lifestyle-induced obesity among adults is increasing rapidly [ 1 ]. Methods Experimental protocol For 8 weeks subjects were prescribed a carbohydrate and calorically-restricted diet individually calculated based upon pre-intervention body composition and resting metabolic rate RMR.

Participants Seventeen males between the ages of 21 and 28 who self-reported as resistance trained defined as consistent whole body resistance training for at least 2 years prior to the onset of the study volunteered for the study. Body composition assessment Total body mass was measured on a digital medical scale Tanita, Tokyo, Japan and height was measured using a standard medical stadiometer Seca, Chino, CA.

Another way that the BCAAs enhance muscle growth is by facilitating growth hormone. A study from Italian researchers found that athletes taking BCAAs for one month had higher levels of growth hormone and growth hormone binding protein after exercise.

GHBP is important because it acts as a carrier for GH in the blood, taking it to the muscles where it can do its job of instigating muscle growth.

In addition, another hormone that BCAAs affect is the catabolic hormone cortisol. This blunting effect on cortisol is critical because cortisol is a catabolic hormone that interferes muscle membrane, which is believed to initiate muscle growth.

Still another way that BCAAs enhance muscle growth is by maintaining higher levels of muscle glycogen, as University of São Paulo Brazil researchers discovered.

Muscle glycogen is the storage form of carbs in muscle cells. Normally, muscle glycogen drops during a workout because it is used to fuel the muscles. This can compromise muscle size because glycogen pulls water into the muscles, keeping them full and large.

Because supplemental BCAAs are readily used for fuel during workouts, muscle glycogen levels are higher after training. By sparing muscle glycogen levels, BCAAs work to maintain muscle size by keeping the muscles full.

Fuller muscles place a stretch on the greater strength gains than those taking a placebo. Another study by Australian researchers reported in a issue of the European Journal of Applied Physiology that six weeks of leucine supplementation not only improved muscle power in outrigger canoeists, but endurance as well.

A study of competitive wrestlers found that those who were supplementing with BCAAs while following a low-calorie diet experienced greater overall weight loss and bodyfat reduction, particularly in the abdominal area, as compared to test subjects who took a placebo.

Of the three BCAAs, it may be leucine that provides the majority of the fat-loss effects. A study by Brazilian researchers reported that leucine supplementation for six weeks significantly reduced bodyfat. They proposed that the increase in protein synthesis stimulated by leucine likely increased energy expenditure, which could help to burn more bodyfat.

With all the benefits of BCAAs, adding them to your regimen should be an easy choice. Yet knowing how and when to add them to your day can make all the difference in the benefits you experience.

FLEX recommends about grams of BCAAs per dose. We also recommend at least four doses per day. These four doses should be taken first thing in the morning, within 30 minutes of working out, within 30 minutes after working out and with your last meal of the day.
