As shown in Table 2, only the height (164.4±6.2 to 165.1±6.6 cm)
significantly increased through the 10 weeks (p b 0.05). Participants'
weight, BMI and waist circumference and fat-free mass did not significantly
differ between baseline and the end of the program(Table 2). Although
fat mass expressed in kilograms was not significantly modified
by the intervention, it was significantly decreased once expressed as a
percentage of total mass (44.5 ± 10.6% to 42.8 ± 9.8%; p b 0.05). The
mean weight variation (weight post intervention minus baseline
weight)was 1.1±3.6 kg butwhen considered individually, the adolescents
showed an important inter-individualweight loss variability from
an 8 kg weight loss to a weight gain of 9.2 kg (Fig. 1A).
As previously shown in this specific group of adolescents [1], a
training effect was observed with a significant increase of the participants'
aerobic fitness indicators. Peak workload (p b 0.05), peak heart
rate (p b 0.01) and the time to reach exhaustion (p b 0.05) were all significantly
improved by the intervention (Table 2).
