The present study aimed to verify the quarantine's effects during a serious viral outbreak on the cardiovascular and performance associated with the Yo-Yo test in a sample of professional soccer players 20 high-level soccer players (n = 20;age: 26 ± 4 years-old;weight: 76 85 ± 6 7 kg;height: 179 ± 6 cm) participated in this study The intermittent Yo-Yo test was performed pre- and post- COVID-19 quarantine in a random order During each test, the soccer players' running performance outcomes were monitored using a portable 5-Hz GPS with a 100 Hz accelerometer and a paired t-test was conducted at a p-value of ≤ 0 05 The main results demonstrated significant differences between pre- versus post-COVID-19 quarantine in the following variables: relative distance (161 7 ± 5 9 &gt; 141 1 ± 33 8 m/min), maximal speed (18 7 ± 0 9 &gt; 18 2 ± 0 6 km/h), acceleration (60 ± 20 frequency &gt; 52 ± 16 frequency), deceleration (34 ± 13 frequency &gt; 27 ± 6 frequency), sprints &gt; 19 km/h [0 8 (0 2;3)% &gt;0 5 (0;0 5)%], and in high intensity running distance [16 48 (2 68;41 64)m &gt; 0 827 (0 164;3 0)m] We concluded that COVID-19-related restrictions and quarantine COVID-19 demonstrated adverse effects on professional soccer players' Yo-Yo tests performance
