Effect of the Bobsleigh Push Time on Race Outcomes and the Enlightenments for Training
Objective:To investigate the effect of the bobsleigh push time on race outcomes and to propose the training enlightenments for the Chinese bobsleigh team for preparing for the Milan Winter Olympics. Methods:Data from the last five Winter Olympics and five years of World Championships were analyzed. Correlation coefficients and independent sample t-tests assessed the relationship between push times and race outcomes,and the difference of the correlation be-tween push time and race outcomes of athletes at different levels. Results:1) For high-level athletes,the push time in the 4-man bobsleigh shows a significant positive correlation with race outcomes across all competitions (P<0.05,r=0.345—0.679). For others,excluding the woman-monobob at the 2022 Beijing Winter Olympics,the 2-man bobsleigh at the 2018 PyeongChang Winter Olym-pics,and the 2-woman bobsleigh at the 2006 Turin Winter Olympics,push time is also significantly positively correlated with race outcomes (P<0.05,r=0.334—0.885). 2) Among athletes of general levels,in the 4-man bobsleigh,2-man bobsleigh,2-woman bobsleigh,and woman-monobob events,push time shows a significant positive correlation with race results in only some competitions (P<0.05,r=0.342—0.727). 3) There are differences in the correlation between push times and race out-comes varied across different tracks. 4) High-level athletes had significantly shorter push times com-pared to general-level athletes (P<0.05),with no significant differences in the correlation between their push times and race outcomes. Conclusions:1) Push time significantly influences race out-comes and it has a high degree of variability in different tracks. 2) Compared to athletes at the gener-al level,the relationship between push times and race outcomes is more stable for high-level ath-letes. 3) The Chinese bobsleigh team should improve foundational and specialized physical training integration during summer preparation,focusing on enhancing maximum strength,lower body ex-plosiveness,and short-distance sprinting abilities related to the bobsleigh pushing ability.
