Eight-week strength training program.
Fig 1.
The figure shows the total duration of daily training sessions during the intervention period. Endurance sessions occurred on Mondays, Wednesdays, and Fridays, while combined strength-endurance sessions were conducted on Tuesdays, Thursdays, and Saturdays. Sundays were used for active recovery. Training time was maintained at approximately 5.5 hours per day.

Overview of TRIMP in 8 weeks intervention training and 8 weeks pre-intervention training.

Comparison of weekly average TRIMP between pre-experiment and experiment.
This figure compares the average Training Impulse (TRIMP) values per week between the pre-intervention phase and the intervention phase. While total TRIMP remained stable, strength training TRIMP increased significantly, indicating an intentional redistribution of training load.

Overview of physiological and psychology indicators.
Fig 4.
Indicators change at 0, 4 and 8 weeks of follow-up period (mean±sd) (O:2000m running; P:Peak Power; Q:SJ).
(O) 2000-meter running time (s) measured at 0, 4, and 8 weeks post-intervention, showing no significant performance decline. (P) SJ height (cm) across the same time points, indicating stable lower-body explosive strength. (Q) Absolute peak power (W) from Wingate test results, demonstrating sustained anaerobic performance levels. Each data point represents the group mean ± SD. No statistically significant regression was observed in any variable over the 8-week follow-up period, suggesting that performance adaptations achieved through concurrent training were maintained even after returning to a traditional training regimen.
