# Weekly Fluctuations in Internal Load and Neuromuscular Performance Across a 10-Week Training Period in Elite Female Boxers

## TL;DR

This study tracked training load and neuromuscular performance in elite female boxers over 10 weeks, finding weekly fluctuations aligned with performance changes.

## Contribution

The study demonstrates the practical use of sRPE-derived internal-load indices to monitor weekly training responses in elite female boxers.

## Key findings

- Weekly sRPE-derived training load, monotony, and strain showed statistically significant fluctuations.
- Neuromuscular performance improved, declined, and partially recovered across the 10-week period.
- Internal-load indices were temporally aligned with neuromuscular performance changes.

## Abstract

This study examined weekly internal load and neuromuscular performance in elite junior female boxers over 10 weeks. Internal load was quantified using session rating of perceived exertion (sRPE), from which weekly monotony and strain were derived. Neuromuscular performance was assessed weekly using wall-sit endurance and a repetitive jump test. Twenty elite junior female boxers (Mean ± SD: 18.9 ± 1.2) were monitored during regular training without experimental manipulation. Weekly sRPE-derived training load, monotony, and strain showed statistically significant week-to-week fluctuations (p < 0.001). Neuromuscular performance improved in week 2, declined during weeks 3–5, and partially recovered in week 6. The findings demonstrated consistent temporal alignment between internal-load indices and week-to-week neuromuscular performance changes within an observational monitoring framework. Inter-individual variability was observed across athletes. Overall, sRPE-derived indices reflected training stress patterns and were aligned with neuromuscular performance changes in elite female boxers, supporting their use for contextual monitoring of weekly training responses. These findings support the practical integration of internal-load and performance monitoring in elite female combat-sport settings. Future research incorporating boxing-specific external-load metrics, physiological markers, and longer monitoring periods may further refine individualized load-management strategies.
