Abstract

PURPOSE: To evaluate the effects of environmental conditions on running performance and performance efficiency index (Effindex). METHODS: Performance data recorded using Polar Pro sensors from eight collegiate female soccer players in nine matches were analyzed during the 2019 competitive season. Effindex and running performance, including total distance covered relative to minutes played (TDREL) and distance covered in five-speed thresholds, were examined for indications of fatigue with rising environmental conditions, including ambient temperature and relative humidity. Matches were separated into three groups based on environmental condition risk: low (Low-Risk; n= 2 matches), moderate (Moderate-Risk; n=3 matches), or high (High-Risk; n=4 matches). Speed thresholds were grouped as follows: walking (WALKREL 0.83 – 1.94 m/s), jogging (JOGREL 1.94- 3.05 m/s), low-speed running (LSRREL3.06-4.16 m/s), high-speed running (HSRREL4.17- 5.27 m/s), and sprinting (SPRINTREL 5.28+ m/s). RESULTS: TDREL was significantly lower in High-Risk conditions. WALKREL, JOGREL, LSRREL, HSRREL , SPRINTREL , and Effindex were significantly greater in Low-Risk conditions when compared to Moderate-Risk conditions. WALKREL, HSRREL , SPRINTREL , and Effindex were significantly greater in Low-Risk conditions when compared to High-Risk conditions. CONCLUSIONS: High-Risk environmental conditions significantly affect performance in female collegiate soccer players. Cooling and timing strategies are advised to mitigate decrements in performance.
