“…Armstrong and Bray (1991) have shown that the time spent in activities with heart rates at 160 beats á min A1 or above was higher in B than in G only during school days but that there were no dierences in the time spent in activities with heart rates of 140 beats á min A1 or more, during either school days or free days. In the same way, Kemper et al (1983) have observed a signi®cantly higher time spent in strenuous pursuits [>10 METS (10 times the basal metabolic rate)] in B than in G from age 12 to 18 years. In the present study, daily MPA was greater in G than in B on school days `0X05.…”

Heart rate (HR) was monitored in 66 French pubertal boys (B, n = 28) and girls (G, n = 38) aged 11-16 years to evaluate habitual physical activity (HPA) over a 1-week period in the winter. The HR and the percentage of heart rate reserve (%HRR) were taken to be indexes of the metabolic activity for the whole day and for the different parts of the day. The HPA was evaluated from the time spent each day below 50%HRR, between 50%-70%HRR and above 70%HRR, which related to the time spent in no or low physical activity (NLPA), moderate physical activity (MPA) and vigorous physical activity (VPA), respectively. No sex differences were observed in the average %HRR each day [%HRRmean, [B 30 (SD 4)%; G 32 (SD 4)%]] or in NLPA [B 715 (SD 61) min, G 711 (SD 81) min] and VPA [B 19 (SD 16) min, G 21 (SD 21) min] throughout the week. During school days, daily %HRRmean was 7% smaller in 14-16 year olds compared to 11-13 year olds. This was linked to a decrease in MPA and a concomitant increase in NLPA (P < 0.05). Daily %HRRmean varied significantly during the week (range: 28-34% HRR). There were significant differences among the periods of the day (P < 0.05). The HR was the greatest during physical education lessons [128 (SD 11) beats x min(-1)], recreation [113 (SD 15) beats x min(-1)] and lunch break [108 (SD 12) beats x min(-1)] and the lowest during the evening [94 (SD 10) beats x min(-1)]. It was only during the lunch breaks that %HRRmean was greater (P < 0.05) on school days than on free days. Of all the teenagers studied 32% were considered active during the week.

“…With regard to the dynamics of aerobic power, most studies indicate that from 6 to 17 years of age absolute peak VO 2 (L-min' 1 ) increases in linearly with increasing body size in males Cooper et al, 1984;Davies et al, 1972;Krahenbuhl et al, 1985). The high correlation between growth and the increase in absolute values of peak VO 2 has also been confirmed in longitudinal studies (Kemper et al 1983;Rutenfranz, 1986). According to Astrand (1952) peak VO 2 expressed per kg of body mass increases from 4 to 8 years of age and then remains constant during growth.…”

“…Attempts are made to discuss this phenomenological material against the background of the ontogenetic development of physiological functions (Bar-Or, 1983a;Blimkie, 1989;Malina and Bouchard, 1991;Rowland, 1996;Shephard, 1982) and the biological maturation of the young organism (Beunen, 1989;Beunen and Malina, 1996;Kemper et al, 1983;Malina and Bouchard, 1991;Malina, 1994). To establish links between the development of motor abilities and biological maturation, several approaches have been used to estimate biological age (Beunen et al, 1984;Bouchard et al, 1976;Hebbelinck and Borms, 1978;Kemper et al, 1983); the timing of the growth spurt and peak height velocity (PHV) ); comparison of children with advanced vs. delayed maturation Carron et al 1977;Kemper et al, 1987); evaluation of sexual maturation stages from the development of the secondary sex characteristics (Armstrong et al 1991;Bloomfield et al 1990;Szczesny and Coudert, 1993); age of menarche (Carron et al 1977;Espenschade, 1940), and determination of sex hormones (Falgairette et al 1991;Viru et al 1998;Welsman et al 1994).…”

“…Body fat in boys however remained at a constant percentage of body mass of about 16070, and in girls it increased from 23070 to 28070 during their teens (Kemper, Dekker, Ootjers, Post, Splinter, Storm-van Essen and Verschuur 1983). Thus while some of the reduction of Vo2max/BM in the girls can be attributed to the relative increase in the proportion of body fat, the decline in lko2max/LBM suggests an additional loss in the functional power of the oxygen-transport system.…”

On the basis of measurement of maximal aerobic power (VO2max) over a period of four years in a teenage population of boys (N = 102) and girls (N = 133), we studied the growth of VO2max in absolute values and in relative values: relative to whole body mass (VO2max/BM), to fat-free mass (VO2max/LBM) and to height squared (VO2max/H2). The changes in VO2max were studied in relation to chronological age (CA), skeletal age (SA), and age relative to peak height velocity (PA). Since no significant testing or measuring effects could be demonstrated and the reproducibility was high, the longitudinal design seems adequate to trace individual growth curves of VO2max. With CA VO2max increases in boys from 2.41/min at age 12+ to 3.81/min at age 17+. The increase in girls is less, from 2.31/min to 2.71/min over the same age range. VO2max/BM remained constant in boys (591/min.kg) and in girls it gradually decreased from 50 at age 12+ to 45 ml/min.kg at age 17+. The decrease in girls has been caused partly by an increase in body fat. When VO2max is aligned on PA, the results show that the peak increase coincides roughly with the age at peak height velocity. It demonstrates that in general in boys and girls during their teens no discrepancy between structural and functional growth occurs as far as VO2max is concerned.
