title: The influence of training on physical and functional growth before, during and after puberty.
abstract: In boys, the ages at which growth rates for body weight, height, VO2max, maximum O2 pulse and VImax reached their peaks were approximately the same (means and SD: 14.64 +/- 0.98, 14.67 +/- 0.99, 14.71 +/- 1.59, 14.38 +/- 1.36 and 14.64 +/- 1.42 years respectively). There was a positive relationship between the peak velocities of functional capacity indicators (VO2max 0.79 +/- 0.19 1.min-1.year-1, O2 pulse max 4.1 +/- 1.20 ml.year-1, VImax 27.3 +/- 7.15 l.min-1.year-1) and the peak growth velocity of weight and/or height (weight 9.1 +/- 1.92 kg.year-1, height 9.8 +/- 1.92 cm.year-1). A positive relationship between the age at peak velocity of VO2max and O2 pulse max with the age at peak velocity for body weight was also found (r = 0.524 and 0.400 respectively). No relationship was revealed between the age at peak velocity on the one hand and the peak velocities of body weight, height, VO2max, O2 pulse or VImax on the other. Moderate training did not influence acceleration in growth--the age at peak velocity and the peaks of the growth rate did not differ in groups with a different regime of exercise (higher - n = 8, medium - n = 9, lower - n = 12; the peak velocity of VO2max--means and SD--being 0.85 +/- 0.15, 0.76 +/- 0.22 and 0.78 +/- 0.17.min-1.year-1 respectively).
