- The aim of this study was two-fold: (i) to analyze the variations of internal load (IL) and well-being between normal and congested weeks in professional futsal (also known as indoor soccer) players and (ii) to analyze variations in training days (MD-1, MD-2 and MD-3 [matchday −1, −2, and −3, respectively]) within weeks. Twenty male professional futsal players (age: 27.8 ± 5.7 years old; height: 173.8 ± 5.6 cm; weight: 71.5 ± 7.9 kg) that participated in the first futsal league of Portugal were monitored in all training sessions and matches during a full season. Session ratings of perceived exertion and a Hooper questionnaire (to measure muscle soreness, stress, fatigue, and sleep) were used to monitor the IL and well-being, respectively. Almost certain large decreases in IL during congested weeks in training session MD-3 were observed (−27.7%, [−35.8;−18.6]). Likely moderate decreases in IL during congested weeks in the MD-2 session were also verified (−9.9%, [−17.2;−2.0]). Regarding muscle soreness, almost certain large decreases were found during congested weeks on MD-3 (−21.2%, [−30.0;−11.3]) and MD-1 (−17.3%, [−26.6;−6.9]). Similar evidence was found for fatigue level, as almost certain large decreases were observed during congested weeks on MD-3 (−23.5%, [−32.9;−12.7]) and MD-1 (−16.6%, [−24.8;−7.4]). Within-week changes during normal weeks revealed almost certain large increases in internal load on MD-2 (93.4%, [78.6;109.3]) and MD-3 (106.7%, [88.2;127.0]) in comparison with MD-1. Also, during congested weeks, almost certain large increases of internal load were observed on MD-2 (77.2%, [53.4;104.7]) and MD-3 (65.7%, [42.8;92.3]) in comparison with MD-1. The major findings of this study revealed meaningful increases of IL, muscle soreness, and fatigue in normal weeks in comparison to congested ones. Within-week changes were also observed, with the greatest loads being observed on MD-3 during normal weeks and on MD-2 during congested weeks.
