Abstract

<b>目的</b>:ボートレーサーの競技成績(勝率)の変化率をアウトカムとし,関連する因子をコホート調査によって検討した。<br><b>方法</b>:対象者は110名のボートレーサー(平均42.7 ± 7.5歳)とし,ベースライン(base line;BL)時,3年後に行われたレース結果の勝率を用い,(3年後勝率-BL勝率)/BL勝率×100にて勝率変化率を算出しアウトカムとした。3年間の勝率変化率と性別,BL時の変数(勝率,年齢,体重,動的バランス能力)および各変数の変化量(体重,動的バランス能力)との関連について,重回帰分析を行った。<br><b>結果</b>:勝率変化率はBL時の年齢および体重と有意に負の関連を示した(p < 0.05)。一方,BL時勝率,性別,動的バランス能力については、関連因子としての有意性は認められなかった。<br><b>結論</b>:ボートレーサーの競技成績の3年間の変化率は,BL時の年齢および体重と負の関連を示した。

<b>Objective</b>: The rates in the competition result (the rates of winning) of boat racers was regarded as the outcome, and related factors were examined by cohort survey.<br><b>Methods</b>: The subjects were 110 boat racers (mean age 42.7 ± 7.5 years old). The rates of winning from racing results conducted at the initial 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, dynamic balance capability), and the amount of change in each variable (weight, dynamic balance capability).<br><b>Results</b>: For subjects, the rate of change in the rates of winning was only significantly associated negative 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.<br><b>Conclusion</b>: The three-year rate of change in the competition result of boat racers subjects was associated negative with age and weight at BL.
