Abstract
This study aimed to evaluate how high- (3x10) versus low-repetition (3x2) resistance training affects (1) muscular strength-endurance and (2) immediate recovery after a high-intensity exercise effort (HIEE). Fourteen college-aged participants (10 males: 24.5 ± 4.9 yrs, 1.76 ± 0.05 m, 86.56 ± 6.90 kg; 4 females: 23.0 ± 2.8 yrs, 1.58 ± 0.09 m, 62.19 ± 5.96 kg) completed a 4-week training program and were divided into two groups: G2 (3x2; 5 males, 2 females) and G10 (3x10; 5 males, 2 females). All subjects performed back squats to failure at 67.5% of baseline 1RM. Repetitions (REPS) and volume load with displacement (VLd) were measured pre- and post-training to assess changes in HIEE performance. Heart rate (HR), blood lactate (BL), and muscle oxygenation (SMO2) were assessed at baseline (PRE), immediately post-exercise (IP), and during recovery at 5 minutes (5P) and 10 minutes (10P). Recovery time data and Pearson’s r correlations between changes in 1RM variables, VLd, scaled VLd, and SMO2 recovery were analyzed using linear mixed effects models. REPS significantly increased in both groups (p > 0.001; g = 1.86 [0.90, 2.79]), but no significant group or time effects were observed for VLd. G10 demonstrated stronger correlations (r = 0.33–0.61) between changes in 1RM and VLd (including scaled VLd) compared to G2 (r = –0.13 to 0.26). No significant group, time, or interaction effects were found for HR, BL, or SMO2 recovery. However, G10 showed a non-significant trend toward greater lactate clearance between 5P and 10P (p = 0.29; g = 0.29 [–0.01, 0.58]). Although both protocols produced similar improvements in strength-endurance, the stronger correlations in G10 suggest potentially different adaptation mechanisms. Additionally, the trend toward improved lactate clearance in G10 may indicate that higher-repetition training facilitates faster recovery following maximal effort exercise.
