“…Comparing anthropometric results (body height, mass and percentage body fat) in this study with the data of other investigators, some authors give significantly higher values than are presented in this study"3'15 but the anthropometric dimensions of our subjects were similar to those presented by ohr5,7, 9, 12,16 others5''"" Maximal oxygen uptake values in untrained boys are similar to the data given by other investigators for the same age group3 8' 16, but some other authors obtained significantly higher Vo2max per kilogram body mass values in untrained boys than are given here' 0' 11 There could be many reasons for the higher Vo2 values in untrained subjects in these studies: they could participate in vigorous physical activity in free time as well as during regular physical education classes in school; they were better endowed for high VO2max values; the method employed in determination of VO2max-All three studies used treadmill running as a mode of exercise: it is well known that treadmill running elicits higher Vo2max values than does the cycle ergometer exercise17* VO2max in absolute and relative terms was significantly higher in the trained than in the untrained group. This could be expected, as swimming is an aerobic exercise which greatly taxes the oxygen transport system.…”

The purpose of this study was to assess maximal aerobic power (VO2max) in trained and untrained 15-year-old boys. The trained subjects (18) were junior swimmers from a Belgrade swimming team, and the untrained ones (12) were from a Belgrade high school. VO2max was directly measured during progressive cycle ergometer exercise using open circuit spirometry. No significant differences in height, mass, percentage fat and vital capacity were noted between the trained and untrained groups. Maximal aerobic power (overall, relative and in relation to lean body mass) in absolute values, and expressed per kilogram of body mass and lean body mass, was 31.5%, 21.2% and 20.6%, respectively, higher in the trained than in the untrained group (P less than 0.05). These data suggest that physical training significantly increases maximal aerobic power in young subjects.

“…The sex difference of VOzmax is also different from that of morphological indices. For both average absolute and relative values, those of boys are greater than those of girls in all age groups, and the difference between boys and girls increases gradually without the phenomenon of girls' morphological values temporarily greater than those of boys, which is also seen in the results of Cumming (1967), Shephard et al (1968), and Kemper and Verschuur (1987). In this study, the age, curves of absolute values of VOamax and VOzmax/stature are similar in boys and girls, but that ofV02max/ weight and V02max/LBM are completely different.…”

The maximal aerobic power of 463 Chinese children and adolescents, 10–19 years, is described. The absolute values of maximal oxygen intake (V̇O2max) in boys and girls were 1.75–3.26 and 1.44–2.10 L/min, respectively. Relative values of V̇O2max per unit stature (V̇O2max/stature) were 12.35–19.42 ml/cm.min for boys and 10.18–13.42 ml/cm.min for girls, values per unit weight (V̇O2max/weight) were 48.60–56.59 ml/kg.min for boys and 39.34–45.56 ml/kg.min for girls, and values per estimated unit lean body mass (V̇O2max/lean‐body‐mass) were 58.98–65.28 ml/kg.min for boys and 54.90–59.04 ml/kg.min for girls. Maximal values of oxygen pulse (V̇O2max/HRmax) were 8.58–16.67 ml/beat for boys and 6.88–10.35 ml/beat for girls. In early adolescence, V̇O2max, V̇O2max/stature, and V̇O2max/HRmax increased with chronological age, but the increment was less in girls. In contrast, V̇O2max/weight and V̇O2max/LBM did not increase with age in boys and girls. All indicators of V̇O2max were lager in boys than in girls. © 1996 Wiley‐Liss, Inc.

“…26 Peak VO 2 also has a weak relationship with the 1500 m running performance of 14-18 years old boys and girls, 27 of which exercise time and distance corresponds to our tests with 1500 m wheelchair racing bouts. In addition, CVs from VO 2 measurements are not as small as CVs from peak power output measurements.…”

Study design: Validation of a new wheelchair racing test. Objective: To assess the reproducibility of test parameters at different, subjectively chosen, intensity levels in wheelchair racing athletes. Setting: Swiss Paraplegic Centre, Nottwil, Switzerland. Subjects: We tested 11 (eight male, three female) young competitive wheelchair racing athletes. Their age was 20.576.4 years, height 164.7716.3 cm and weight 54.179.2 kg. Average weekly training time was 6.872.7 h. All had been engaged in regular training for over 3.972.8 years.Methods: Within a period of 371 days, every athlete completed two identical tests in their own racing chair on a training roller. The tests consisted of five 1500 m bouts at routine training intensities of 1 (warm-up) up to 5 (race speed), with a rest of 2 min between each bout. The athletes were blinded to all the collected data during the whole of the test, except for indications of the 500, 1000 and 1500 m markers. We measured the overall time (for 1500 m), average speed, stroke frequency, heart rate, rate of perceived exertion (RPE) and the concentration of lactic acid for all five intensity bouts. In order to get a measure on how reproducible these intensity levels were, we compared the two tests of each athlete with each other, and calculated the rootmean-squared coefficients of variation (CV) for all measured parameters during every bout. Results: CVs of the measured data show that the most reproducible values were found for bout 5 (2.6-7.9%); except for the lactic acid parameter. The heart rate (CV: 3.1-6.4%) and stroke frequency (CV: 6.5-7.9%) parameters reached rather constant values throughout all five bouts. Lactic acid concentrations showed very high CVs (16.8-29.7%). Conclusion: We conclude that this test is, with the exception of the lactic acid measurements, well reproducible, and particularly suitable for young wheelchair athletes. We find it to be a helpful tool for improving awareness for the individual training intensities, and for pursuing the development of the training process, as particularly the high-intensity bouts are well reproducible.
