Neuromuscular Performance and Training Workload Over an In-Season Mesocycle in Elite Young Soccer Players

Purpose: The purpose of this study was to assess neuromuscular performance capabilities over an in-season mesocycle in earlycareer professional soccer players and examine the relationship with training workload. Methods: Neuromuscular performance capabilities (isometric knee extensor: peak force, rate of force development, and peak twitch force) of 12 professional soccer players were assessed weekly over a 6-week period. Training and match workload were also recorded over the same period for each player (high-intensity running distance). Changes in neuromuscular performance and workload variables were analyzed. Results: There was evidence of fluctuations in neuromuscular performance capability over the mesocycle that reached statistical (P < .05) and practical (13.3% [peak-to-peak]) significance alongside interweek heterogeneity in training and match workload (similar to 17.5% [coefficient of variation], P < .05). Congruence among fluctuating patterns of intramesocycle training load and concomitant neuromuscular performance responses was noted over time for acute training load and acute:chronic workload ratio with peak force and rate of force development. Conclusion: Neuromuscular performance capabilities fluctuate over an inseason mesocycle and are influenced by high-intensity running workload, emphasizing the need for acute monitoring in elite soccer players.

Automated summary

This study aimed to evaluate the neuromuscular performance capabilities of early career professional soccer players over an in-season mesocycle and examine the relationship with training workload. The results showed fluctuations in neuromuscular performance capabilities and their association with high-intensity running workload. The findings highlight the importance of acute monitoring for elite soccer players.
