dc.description.abstractPurpose Training methods that require maximal intensity efforts against light and heavy resistance are commonly used for athletic development. Typically, these sessions are separated by at least 48 h recovery on the assumption that such efforts elicit marked fatigue of the central nervous system (CNS), but this posit has not been well studied. The aim of the study was to assess the etiology and recovery of fatigue after heavy-resistance (strength), jump, and sprint training methods. Methods Ten male athletes completed three training sessions requiring maximal efforts that varied in their loading characteristics: (i) heavy-resistance exercise (10 × 5 back squats at 80% one-repetition maximum [1RM]) (STR), (ii) jumping exercise (10 × 5 jump squats) (JUMP), and (iii) maximal sprinting (15 × 30 m) (SPR). Preparticipants, postparticipants, and 24-, 48-, and 72-h postparticipants completed a battery of tests to measure neuromuscular function using electrical stimulation of the femoral nerve, and single- and paired-pulse magnetic stimulation of the motor cortex, with evoked responses recorded from the knee extensors. Fatigue was self-reported at each time point using a visual analog scale. Results Each intervention elicited fatigue that resolved by 48 (JUMP) and 72 h (STR and SPR). Decrements in muscle function (reductions in the potentiated quadriceps twitch force) persisted for 48 h after all exercise. Reductions in voluntary activation were present for 24 h after JUMP and SPRINT, and 48 h after STR. No other differences in CNS function were observed as a consequence of training. Conclusion Strength, jump, and sprint training requiring repeated maximum efforts elicits fatigue that requires up to 72 h to fully resolve, but this fatigue is not primarily underpinned by decrements in CNS functionen_US
