Adherence to prescribed training intensity (i.e., swim speed) has been conveyed as a key parameter regarding improvements in seasonal performance. Evidence has also suggested swimmers have difficulty complying with coach-prescribed training. How this compliance is affected by a coaching presence and oversight has yet to be examined.
The purpose of this study was to determine swimmers' compliance to prescribed training intensity during 3 observational conditions using activity monitors.
Individualized prediction equations were created via linear regression analyses for intensity using arm-stroke and leg-kick activity counts during a series of seven 91.4-m swim bouts in a group of 17 collegiate swimmers. Equations were used to calculate intensity performed during a standardized training session during which only the observational condition varied (e.g., a coach present on deck, no coach present on deck, and an appointed observer in addition to the coach present on deck). Compliance was calculated from the difference between prescribed training intensity and performed swim intensity. Comparisons were made between observed coaching conditions for compliance using a repeated-measures analysis of variance.
Swimmers' compliance to prescribed training intensity during the no-coach condition was less compared with the other conditions, including (a) when a coach was present and (b) when a coach and an additional observer were present (η = .58).
The presence of a coach or lack thereof appeared to be critical in terms of swimmers' compliance to prescribed training intensity. Additional observation by nonsupervisory individuals appeared to have no significant effect on swimmers' compliance.
坚持规定的训练强度(即游泳速度)已被视为提高赛季成绩的关键参数。有证据还表明,游泳运动员难以遵守教练规定的训练。这种依从性如何受到教练在场和监督的影响尚待研究。
本研究的目的是使用活动监测器确定游泳运动员在三种观察条件下对规定训练强度的依从性。
通过线性回归分析,利用17名大学生游泳运动员在一系列七次91.4米游泳回合中的手臂划水和腿部踢水活动计数,创建了强度的个性化预测方程。这些方程用于计算在标准化训练课程中执行的强度,在此期间只有观察条件不同(例如,教练在泳池边、教练不在泳池边以及除教练在泳池边外还有一名指定观察员)。依从性通过规定训练强度与实际游泳强度之间的差异来计算。使用重复测量方差分析对观察到的教练条件下的依从性进行比较。
与其他条件相比,在没有教练的条件下,游泳运动员对规定训练强度的依从性较低,包括(a)教练在场时和(b)教练和额外观察员在场时(η = 0.58)。
教练的在场与否似乎对游泳运动员对规定训练强度的依从性至关重要。非监督人员的额外观察似乎对游泳运动员的依从性没有显著影响。
