May improve Yo-yo recovery after short pre-season in futsal players; hypothesis-generating for vagal HRV links.

Short pre-season training in futsal players improves repeated-sprint ability and intermittent recovery performance alongside increases in vagal-related heart rate variability indices.
Oliveira et al. (2012) conducted an observational in Professional futsal players (n=11). Pre-season futsal training vs. Baseline (beginning of pre-season) was evaluated on Yo-yo intermittent recovery test level 1 (Yo-yo IR1) distance (d 0.77, 95% CI 0.42-1.11, p=0.002). A short 3-week pre-season training period significantly increased Yo-yo intermittent recovery test distance from 1244 m to 1491 m (d 0.77) in professional futsal players.
