The Periodic Impact of Low-Temperature Exposure on the Physical Fitness of Winter Sports Athletes
OBJECTIVE:This study aims to investigate the periodic effects of low-temperature exposure on the physical fitness of winter sports athletes.METHODS:Using mice as an experimental model,we conducted experiments under simulated low-temperature conditions of rain,snow,and freezing,exposing mice intermittently for a duration of 7 days.The study observed the mice's exhaustion swimming time under intermittent exposure to the cold environment.RESULTS:A significant reduction in exhaustion swimming time was revealed in the low-temperature environment(P＜0.01),indicating a detrimental impact of low-temperature exposure on the physical fitness of mice.However,in the group of mice with intermittent exposure for 6 days,although there was some recovery in exhaustion swimming time,this improvement did not reach statistical significance.This study contributes to understanding the patterns of physical fitness changes in mice under low-temperature conditions and provides experimental support for exploring the impact of these changes on the physical fitness of winter sports athletes.
