Effects of Spatial Environmental Noise on Athletes' Physiological States During Training

This study aims to evaluate the effect of artificial environment spatial noise on the physiological state of athletes and thus provide scientific training and competition strategies to ensure that athletes maintain their optimal performance in various environments.

This study adopted a retrospective research design. Eighty subjects were selected from the School of Physical Education. Physiological indicators under different noise conditions were collected. For the intergroup comparison of physiological indicators at different noise levels, one-way analysis of variance was used, followed by post hoc multiple comparisons via the least significant difference test. Finally, a simple linear regression model was constructed.

The Philip L. Rice questionnaire showed that 87.5% of athletes had severe occupational stress. Systolic blood pressure was weakly correlated with noise ( R2  = 0.19). Diastolic blood pressure was moderately correlated with noise ( R2  = 0.22). Mean arterial pressure was weakly correlated with noise ( R2  = 0.19, P < 0.001). Heart rate was strongly correlated with noise ( R2  = 0.62, P < 0.001). Respiratory rate was strongly correlated with noise ( R2  = 0.56, P < 0.001).

The noise environment has a negative effect on the physiological state of athletes. This negative effect may reduce their training effects and competitive performance. Therefore, providing suitable training environments for athletes, reducing noise interference, and conducting adaptive training are crucial to improve the competitive levels of athletes.
