Interplay of Biomechanical, Energetic, Coordinative, and Muscular Factors in a 200 m Front Crawl Swim

Table 1

The beta coefficients (𝑘) determined to identify the importance of the factors included in the multiple linear regression models computed for the mean for the overall 200 m performance, as well as for each individual performance lap.
