Abstract

Short-term alactic anaerobic performance in jumping (5 consecutive jumps with maximal effort), sprint running (8 m) and stair climbing (modified Margaria test) were measured in 75 obese subjects (BMI: 40.3±5.0 kg/m 2) and in 36 lean control subjects (BMI: 22.4±3.2 kg/m 2) of the same age and gender distribution. The results show that obese subjects attained a significantly lower specific (per unit body mass) power output both in jumping (W spec,j; pspec,s; pspec,s (and hence the vertical velocity in climbing, v v) was closely correlated with W spec,j (R 2=0.427, ps; pc,r; pspec,j seems to be a determinant of the poorer motor performance of obese, being significantly correlated with: I) the vertical displacement of the centre of gravity (R 2=0.853, pv in stair climbing; and III) with T c,r (R 2=0.492, ps (R 2=0.266, p2=0.454, p
