The purposes of this study were to: i) analyze the variations of acute and chronic training load and well-being measures during three periods of the season (early, mid and ending); and ii) test the associations between the weekly training load and well-being measures during different periods of the season and overall. Thirteen professional volleyball players from a team competing in the 1st Portuguese volleyball division (age: 31.0 ± 5.0 years; height: 1.94 ± 0.07 m; body mass: 88.9 ± 7.6 kg) were monitored during an entire season. Weekly acute (wAL) and chronic load (wCL), acute:chnonic workload ratio (wACWL) and training monotony (wTM) were calculated during all weeks of the season. The weekly values of muscle soreness (wDOMS), stress (wStress), fatigue (wFatigue), sleep (wSleep) and hooper index (wHI) were also obtained across the season. The mid-season had meaningfully low values of wAL (-26.9%; ES [effect size]: -1.12) and wCL (-28.0%; ES: -2.81), although had greater values of wACWL (+38.9%; ES: 2.81) compared to early season. The wCL (+10.6%; ES: 0.99), wStress (44.6%; ES: 0.87) and wHI (29.0%; ES: 0.62) were meaningfully greater during the end of season than in mid-season. Overall, wAL presented very large correlations with wDOMS (r = 0.80), wSleep (r = 0.72) and wFatigue (r = 0.82), however wCL, wACWL and wTM did not present meaningful associations with well-being variables. The results of this study suggest that the load was meaningfully higher during early season, however stress was higher during the final stages of the season. Overall, it was also found that the acute load is more highly correlated with well-being status and its variations, than chronic load or training monotony.
