Influence of Neuromuscular Fatigue Accumulated During Training on Subsequent Chronic Adaptations: PROTECT-10 (PROTECT-10)
A 13-week longitudinal experimental study designed to determine how the level of neuromuscular fatigue induced by strength training influences chronic adaptations. Four assessment periods (pre-protocol, mid-point 1, mid-point 2, and post-protocol) will be used to measure neuromuscular, physiological, and structural parameters. A reference group will be included to assess measurement variability across the evaluation phases (this group will only undergo these assessments), while an experimental group will follow a standardized training protocol (in addition to the assessment phases).

Detaljerad beskrivning
Physical training is based on the dose-response principle, whereby the applied load determines the resulting adaptations. However, a higher dose does not consistently lead to greater gains (Hass et al., 2000; Mitchell et al., 2012), and the precise role of neuromuscular fatigue in chronic adaptations remains a subject of debate. Some studies suggest that fatigue-specifically peripheral fatigue, which directly reflects metabolic disturbances within the muscle-serves as a key stimulus for promoting neuromuscular adaptations (Rooney et al., 1994), while others have observed no significant effect (Folland et al., 2002). These discrepancies can be attributed to several factors: the lack of precise quantification of fatigue; the failure to distinguish between central and peripheral fatigue (the latter being a critical factor) (Hureau et al., 2022); and the failure to account for differences in fatigability between men and women (Hunter, 2016). Furthermore, recent research indicates that peripheral fatigue is regulated at an individual threshold by the tone of type III-IV muscle afferents, which modulate the central motor drive to limit the accumulation of fatigue (Amann et al., 2015; Hureau et al., 2016). Gaining a better understanding of how this threshold-along with its sensitivity and potential plasticity through training-influences the adaptive response is essential for optimizing exercise prescription, both for performance and for health.

Inget ingripande: Reference
This group will undergo only the assessment periods, without participating in the training program. It will allow for the monitoring of variations related to the passage of time, the repetition of tests, and measurement variability. This group will thus serve as a reference, and its results will be compared with those of the experimental group in order to estimate the actual effects of the training and to distinguish between "responders" and "non-responders" (Padilla et al., 2020; Bossi & Mata, 2025). |
