Abstract

BACKGROUND

This study aimed to compare the aerobic capacity in swimming, cycling and arm cranking in swimmers aged 11-13 years.

METHODS

Eleven swimmers (mean age, 12.1 ± 1.0 years) performed three incremental exercise tests. One of the tests was performed under specific conditions (front crawl swimming), and the other two were under non-specific conditions (cycling and arm cranking). Data on the pulmonary gas exchange were recorded using the portable analyser MetaMax 3B (Cortex, Leipzig, Germany). One-way analysis of variance for repeated measures was employed to test the null hypothesis and determine statistically significant differences between the indicators obtained under specific and non-specific testing conditions. Pearson's correlation coefficient was calculated to assess the relationships between the indicators of the pulmonary gas exchange.

RESULTS

The relative peak oxygen uptake (V̇Opeak) value during swimming was 49.3 ± 6.2 mL/kg/min, which was higher than that during arm cranking (39.6 ± 7.3 mL/kg/min; P < 0.01) but lower than that during cycling (54.3 ± 7.8 mL/kg/min; P < 0.01). The peak minute ventilation (V̇peak) value during swimming (84.9 ± 12.6 L/min) was higher than that during arm cranking (69.4 ± 18.2 L/min; P < 0.01) but lower than that during cycling (98.4 ± 15.4 L/min; P < 0.01). Strong positive correlations were observed in the absolute and relative V̇Opeak values between swimming and cycling (r = 0.857, P < 0.01; r = 0.657, P < 0.05) and between swimming and arm cranking (r = 0.899, P < 0.01; r = 0.863, P < 0.05). A strong positive correlation was also observed in V̇peak values between swimming and arm cranking (r = 0.626, P < 0.05).

CONCLUSION

Swimmers aged 11-13 years showed V̇Opeak and V̇peak values during the specific swimming test greater than those during arm cranking but lower than those during cycling. However, aerobic capacity parameters measured during specific swimming conditions correlated with those measured during non-specific arm cranking and cycling conditions.

摘要

背景

本研究旨在比较11至13岁游泳运动员在游泳、骑自行车和手摇曲柄运动中的有氧能力。

方法

11名游泳运动员（平均年龄12.1±1.0岁）进行了三项递增运动测试。其中一项测试在特定条件下（自由泳）进行，另外两项在非特定条件下（骑自行车和手摇曲柄运动）进行。使用便携式分析仪MetaMax 3B（德国莱比锡Cortex公司）记录肺气体交换数据。采用重复测量的单因素方差分析来检验原假设，并确定在特定和非特定测试条件下获得的指标之间的统计学显著差异。计算Pearson相关系数以评估肺气体交换指标之间的关系。

结果

游泳过程中的相对峰值摄氧量（V̇Opeak）值为49.3±6.2毫升/千克/分钟，高于手摇曲柄运动时的值（39.6±7.3毫升/千克/分钟；P<0.01），但低于骑自行车时的值（54.3±7.8毫升/千克/分钟；P<0.01）。游泳过程中的峰值分钟通气量（V̇peak）值（84.9±12.6升/分钟）高于手摇曲柄运动时的值（69.4±18.2升/分钟；P<0.01），但低于骑自行车时的值（98.4±15.4升/分钟；P<0.01）。在游泳和骑自行车之间的绝对和相对V̇Opeak值（r=0.857，P<0.01；r=0.657，P<0.05）以及游泳和手摇曲柄运动之间（r=0.899，P<0.01；r=0.863，P<0.05）观察到强正相关。在游泳和手摇曲柄运动的V̇peak值之间也观察到强正相关（r=0.626，P<0.05）。
