The Difference in Neuromuscular Fatigue and Workload During Competition and Training in Elite Cricketers

Purpose: To firstly, assess changes in neuromuscular function via alterations in the countermovement jump strategy, after training and two forms of competition. Secondly, to compare the relationship between workloads and fatigue in seam bowlers and non-seam bowlers. Methods: Twenty-two professional cricketers’ neuromuscular function was assessed at baseline, immediately post and +24 h post-training, as well as after multi-day and one-day cricket events. In addition, perceptual (rating of perceived exertion; RPE and soreness) measures and external loads (Player LoadTM, number of sprints, total distance, overs) were monitored across all formats. Results: Seam bowlers covered more distance, completed more sprints and had a higher RPE in training (P < 0.05), without any difference in soreness compared to non-seam bowlers. Interestingly, compared to seam bowlers, the non-seam bowlers peak force decreased post-24 h compared to baseline only in one-day cricket (95% CI 2.1 –110.0 N; P < 0.04). There were no pre-post training or match differences in jump height or alterations in jump strategy (P > 0.05). Seam bowlers increased their peak jumping force from baseline to immediately post training or game (95% CI 28.8 – 132.4 N; P < 0.01) but decreased between post-cricket to +24 h (95% CI 48.89 – 148.0 N; P < 0.001). Conclusion: Seam bowlers were more accustomed to high workloads compared to non-seamers and, thus, more fatigue resistant. Changes in jump height or strategy do not appear to be effective methods of assessing fatigue in professional crickets. More common metrics, such as peak force, are more sensitive.
