Twelve participants were included in this case report, with four serving as the test group and eight serving as the control group. All participants wore a Polar GPS unit and a Whoop Strap. The Polar unit was worn during games and practices and used to collect metrics of physical workload. The Whoop strap was worn during daily activities, including periods of sleep, to collect metrics of sleep and recovery. Data were analyzed via descriptive statistics (mean difference ± standard deviations), and T-tests were used to evaluate between-group differences (p &lt; 0.05). To further analyze clinical significance, the Smallest Worthwhile Change (SWC) and Cohen’s d effect sizes were calculated. The results indicated that COVID-19 had the greatest effect on heart rate and sleep metrics with smaller, yet still clinically meaningful, effects on athletic performance. The results show the multisystem effect of COVID-19 on women’s basketball players, including both a physiological and performance decrement during training and less efficient recovery. This was the first study to examine the direct impact of COVID-19 on athletic performance and recovery, and it provides insight into the importance of proper return-to-play considerations.</p> Julie K.

This study set out to use various parameters to measure the physical strength of a player. The parameters include body mass (kilograms), height (centimeters), 30 m sprinting, vertical jump (centimeters), standing long jump (centimeters), 1 RM back squat (kilograms), 1 RM bench press (kilograms), pull-ups, 3 km running and body composition. The performance of a sample of 31 ice hockey players from China on the mentioned parameters was compared to the world’s top performers in ice hockey games, USA, and it was realized that players with generally lower scores on the factors tend to perform dismally in the game. China has been behind the USA in the world’s rankings, and their performances were generally lower compared to their US counterparts. Data was collected by trained experts and analyzed through Microsoft Excel software. The information from this research is basically an eye-opener to the Chinese female ice hockey stakeholders, including players, coaches, and medical personnel, on the areas that need attention to maintain world-class performances.</p> Qian Zhang Lin Yang Naiyuan Tian Tieyi Wang Todd Edward Burkey Copyright (c) 2024 Qian Zhang, Lin Yang, Naiyuan Tian, Tieyi Wang, Todd Edward Burkey http://creativecommons.org/licenses/by/4.0 2024-05-08 2024-05-08 3 2 9 14 10.24018/ejsport.2024.3.2.158
