To develop an equation to provide the peak power (PP) through a specific stimulus performed in an aquatic environment, as well as to correlate morphological, anthropometric and strength variables with rowing performance.
The sample consisted of 16 elite young rowing athletes of both sexes (15.7 ± 1.21 years). The strength of upper limbs and lower limbs was verified. To analyze the PP, a 100-m Sprint test was performed on an indoor rowing type ergometer, and after a 72-hour wash-out, the test was repeated in an aquatic environment on a vessel equipped with a global position system. Body composition was analyzed by examining bone densitometry with an X-ray source and maturation was verified by anthropometry.
The tests for water sprint and indoor rowing showed significant reliability (ICC = 0.695; p = 0.0007). The PP aquatic showed reliability with that acquired in indoor rowing (ICC = 0.897; p<0.0001) and was related to maturation (p<0.05). The morphology, anthropometry and strength of the upper limbs were related to the sprint and peak strength in both tests (p<0.05).
The equation for the PP in aquatic environment presented by the present study is highly reliable with an indoor ergometer digital ergometer.
开发一个方程,以提供在水上环境中进行特定刺激的峰值功率(PP),并将形态、人体测量和力量变量与划船性能相关联。
样本由 16 名男女精英青年划船运动员组成(15.7 ± 1.21 岁)。对上肢和下肢的力量进行了验证。为了分析 PP,在室内划船式测功仪上进行了 100 米冲刺测试,在 72 小时洗脱期后,在配备全球定位系统的船只上的水上环境中重复进行了该测试。通过 X 射线源进行骨密度测量来分析身体成分,并通过人体测量法验证成熟度。
水上冲刺和室内划船测试的可靠性测试结果显著(ICC = 0.695;p = 0.0007)。水上冲刺的 PP 与室内划船的 PP 具有可靠性(ICC = 0.897;p<0.0001),并且与成熟度有关(p<0.05)。上肢的形态、人体测量和力量与两种测试中的冲刺和峰值力量有关(p<0.05)。
本研究提出的水上环境中 PP 的方程与室内测功仪数字测功仪具有高度可靠性。
