Inacio, M, Dipietro, L, Visek, AJ, and Miller, TA. Influence of upper-body external loading on anaerobic exercise performance. J Strength Cond Res 25(4): 896-902, 2011-The purpose this study was to assess the threshold where simulated adipose tissue weight gain significantly affects performance in common tasks determine whether differences exist between men women. Forty-six subjects (men = 21; women 25) were tested for vertical jump, 20- 40-yd dash, 20-yd shuttle tests under 6 different conditions (0, 2, 4, 6, 8, 10% added body weight). Results compared each subject's baseline values (0% condition). demonstrate significant decrements performance, starting at 2% condition, both genders, every test (p < 0.05). On average, jumped 4.91 ± 0.29 9.83 0.30 cm less, increased agility times from 5.49 0.56 5.86 0.61 seconds, sprint 7.80 0.96 8.39 1.07 seconds (2-10%, respectively; p When lower-body power corrected total mass, exerted more than did condition. Conversely, when lean only This demonstrates that specific performed, increases as low results decreases Moreover, these tests, tend express same decrements.
