Special Issue Information

Dear Colleagues,

Sports nutrition has a major role in influencing performance, physical fitness, recovery and adaptation capacity, as well as an athlete's well-being and health. An important element of modern sports research is to support the development of dietary supplements through various methods and technologies aimed at accelerating post-exercise recovery, protecting the body, and replenishing losses of energy and micro- and macronutrients. Many supplements still require well-controlled research on the mechanisms of action and the final performance effect. Even well-studied supplements often require further research in order to evaluate personalized and individualized effectiveness across different sports, training periods, and populations and to assess the effects of synergism or antagonism as a result of combining the intake of several different preparations.

Moreover, the incorrect use as well as abuse of supplements are related to serious health and sports lawfulness problems. The intake of some of these substances may present certain adverse effects that interfere with sports performance and health. The suitability of the use of supplements should be assessed, and the doses and timing of use should be adapted to individual needs. Therefore, appropriate nutritional guidelines are also an essential component of the present research.

In response, we welcome submissions to this Special Issue that provide sound knowledge concerning the supplements required for optimizing the health and sports performance of athletes as well as people who practice sports recreationally. We encourage submissions of original papers and systematic reviews in this field.

Background: It has been suggested that supplementation with Tongkat Ali may affect testosterone concentrations; moreover, whether this influences body composition is unclear. Thus, the purpose of this investigation was to determine if four weeks of Tongkat Ali (400 mg daily dose) supplementation affected body composition and salivary free testosterone concentrations. Methods: Thirty-three exercise-trained males (n = 19) and females (n = 14) volunteered for this investigation (mean ± standard deviation: age 33.1 ± 13.0 years; height 171.1 ± 11.3 cm; body mass 77.4 ± 16.8 kg; average total years of training 13.9 ± 13.2; average hours of resistance training/week 4.2 ± 2.5; average hours of aerobic exercise/week 3.4 ± 2.8; average hours of other exercise/week 1.1 ± 2.0). Research participants were pre- and post-tested for body composition (InBody 270), Profile of Mood States (POMS), handgrip strength, and sleep (Pittsburgh Sleep Quality Index [PSQI]). In a subset of the research participants, saliva samples were collected and analyzed for cortisol and free testosterone. The research participants consumed 400 mg of Tongkat Ali or a placebo (rice flour) daily for four weeks. Results: There were no between-group differences (p > 0.05) for body composition (delta score, mean ± SD: lean body mass kg-treatment −0.5 ± 1.9, placebo −0.4 ± 0.7; fat mass kg-treatment −0.5 ± 1.6, placebo 0.3 ± 1.0, % fat treatment −0.1 ± 1.4, placebo 0.5 ± 1.1). Moreover, there were no differences between groups for any additional assessments (e.g., handgrip strength, mood, sleep, and salivary free testosterone and cortisol). Conclusions: Four weeks of supplementation with Tongkat Ali in exercise-trained males and females does not affect body composition, mood, sleep, vigilant attention, handgrip strength, cortisol, and free testosterone.
