Chronic oral ATP supplementation benefits cardiovascular health, muscular performance, body composition, and recovery while attenuating muscle breakdown and fatigue. A single 400 mg dose of oral ATP supplementation improved lower body resistance training performance and energy expenditure in recreational resistance trained males, however, the minimal effective dose is currently unknown. Twenty recreationally trained men (age 28.6 ± 1.0 years, body mass 81.2 ± 2.0 kg, height 175.2 ± 1.4 cm, 1RM 141.5 ± 5.0 kg) consumed a single dose of either 400 mg, 200 mg, or 100 mg ATP (PEAK ATP, TSI USA LLC, Missoula, MT, USA) or a placebo in a randomized, placebo-controlled crossover design, separated by a one week wash out between treatments. After warm-up, participants performed 4 sets of half-squats using free-weights until movement failure separated by 2 mins of rest between sets. In comparison to placebo, 400 mg ATP significantly increased the number of set 1 repetitions (+13%, = 0.04), and numerically increased total repetitions (+7%, = 0.19) and total weight lifted (+6%, = 0.22). 200 mg ATP numerically increased set 1 repetitions (+4% = 0.47), while 100 mg ATP showed no improvements over placebo. 100 mg ATP (-4%, < 0.05) and 400 mg ATP (-4%, = 0.11) decreased the perceived rate of exertion compared to placebo. In this study, the effective minimal dose of acute oral ATP supplementation during resistance exercise to increase performance was determined to be 400 mg, while as little as 100 mg showed improvements in perceived exertion.
