Objective: The rates in the competition result (the rates of winning) of boat racers was regarded as the outcome, and related factors were examined by a cohort survey.
Methods: The subjects were 110 boat racers (mean age 42.7 ± 7.5 years old). The rates of winning from racing results conducted at the baseline (BL) and three years later were used. Changes in the rates of winning were calculated as (the rates of winning three years later – BL the rates of winning) / BL the rates of winning x 100, which was used as the outcome. Multiple regression analysis was performed on the relationship between the rate of change of the three-year rates of winning and sex, variables at BL (the rates of winning, age, weight, and dynamic balance capability), and the amount of change in weight and dynamic balance capability.
Result: The rate of change in the rates of winning was inversely associated with age and weight at BL (p< 0.05). In contrast, sex, and dynamic balance capability were not admitted as related factors in terms of their significance.
Conclusion: The three-year rate of change in the competition result of boat racers was inversely associated with age and weight at BL.
