Abstract
Aim: To verify the effects of a 2-week of high-intensity interval training (HIIT) on physical performance in young female athletes. Methods: female rugby players (n = 13; 15.92 ± 0.76 years old) participated in an 8-session of HIIT supervised through online video calls for two weeks. They were evaluated pre- and post-HIIT for 3-min of burpees, 1-min of sit-ups, maximum push-ups, and 1-min of squats. Perceptions related to training protocols were collected through the Physical Activity Enjoyment Scale (PACES) post-intervention. Results: Significant improvements in burpees (pre:54.15 ± 18.03 and after: 63.15 ± 15.18), sit-ups (pre:24.38 ± 13.38 and after: 31.15 ± 13.15), push-ups (pre: 9.46 ± 6.59 and after: 13.85 ± 7.33) and squats (pre: 48.00 ± 8.37 and after: 54.85 ± 8.79) were observed. PACES revealed positive perceptions related to the enjoyment of participating in this HIIT. Conclusion: Virtually supervised HIIT improved physical performance in young female athletes during the COVID-19 pandemic, and maybe an efficient strategy for the quarantine period.

Due to the context of the global pandemic caused by Coronavirus Disease 2019 (COVID-19), athletes of team sports had their training and competitions canceled or postponed during the year 20201
The project in which the athletes participate collected the signature of the consent form of the legal guardians and the consent form of the athletes to carry out the investigation and the project was approved by the local Ethics Committee under the number #2.243.675
This study investigated the effects of a 2-week home-based High-intensity interval training (HIIT) on physical performance through online supervised training during COVID-19 quarantine
Summary
Due to the context of the global pandemic caused by Coronavirus Disease 2019 (COVID-19), athletes of team sports had their training and competitions canceled or postponed during the year 20201. Athletes are finding challenges to mitigate the loss of physical conditioning, strength, power, and muscle mass during social isolation[2]. In order to minimize the consequences of the COVID-19 quarantine related to athletes’ physical fitness, strategies to organize guidance to multidisciplinary support, and to plan a strength and conditioning training at home with adequate space and accessible materials have been recommended[3]. A study showed that 12 weeks of three 12-min HIIT sessions per week improve muscle strength and cardiovascular fitness in teenagers[5]. Calisthenics HIIT protocols can improve physical fitness[8], and it seems to be an effective strategy for home-based training[9,10]. Using homebased HIIT protocols in team-sport young athletes can mitigate losses or maintain their physical fitness during the COVID-19 quarantine
