Abstract

Purpose: To discover the effect of different training stimuli on the time course of recovery of fatigue from competitive youth football matches and the role that the Central Nervous System plays in this. Method: Ten participants from a Premier League football academy were recruited. Each participant completed preliminary trial testing prior to six testing sessions completed for each of the two different training weeks. Transcranial magnetic stimulation, femoral nerve stimulation and electromyography were used to measure electrical activity within the vastus lateralis during maximal voluntary contractions of an isometric knee extension. The results were recorded to assess neuromuscular function pre-match, post-match and during prior to each training session in the following week. Results: There were significant differences dependent on the day of testing for MVC (p = <0.001), TMS %VA (p = 0.020), PS deficit (p = 0.043) and PS %VA (p = 0.030). Central and peripheral fatigue were reduced in participants in comparison to previous studies. However, peripheral fatigue was significantly lower than central fatigue for the following values: Post-match deficit in TW-A (p = 0.008); Tuesday deficit in TW-A (p = 0.044); Post-match deficit in TW-AN (p = 0.043), Tuesday deficit in TW-AN (p = 0.047); Post-match %VA in TW-A (p = 0.026); Tuesday %VA in TW-AN (p = 0.031). There were no significant differences between the two training weeks for deficit or %VA for either TMS or PS, suggesting that both methods of training elicited similar central and peripheral recovery. Conclusion: These results agree with previous research that individuals recover from both central and peripheral fatigue as time passes from a previous match. This study finds that the effects of peripheral fatigue were less than central fatigue which opposes previous studies, possibly due to the elite level and the age of the athletes.
