Abstract

The aims of this study were to investigate the impact of high-intensity, low-volume (HRT) vs. moderate-intensity, high-volume resistance training (MRT) vs. soccer training only (CON) on changes in strength, power, and speed, and to compare delayed onset muscle soreness (DOMS) between groups in male academy soccer players (ASP). Twenty-two ASP (age: 18±1 years) were assigned to either HRT (n=8), MRT (n=7) or CON (n=7). HRT completed 2 sets of 4 repetitions parallel back squat (PBS) repetitions at 90% 1RM, while MRT performed 3 sets of 8 repetitions PBS repetitions at 80% 1RM, both once a week for six-weeks in-season, alongside regular soccer training. All groups completed the following pre- and post-training assessments: 3RM PBS; bilateral vertical and horizontal countermovement jumps (CMJ); squat jump (SJ); 30m sprint. DOMS was assessed via visual analogue scale throughout training. HRT and MRT experienced similar increases compared to CON in absolute PBS 3RM (+16±8% vs. +27±16% vs. +2±3%, p<0.001), SJ height (+6±6% vs. +11±7% vs. -7±6%, p=0.001), CMJ height (+8±3% vs. +10±6% vs. -4±10%, p=0.008) following training. There was a greater increase in PBS 3RM relative to body mass following HRT than MRT and CON (+23±8% vs. +16±14% vs. +3±4%, p=0.001) and horizontal CMJ distance improved in HRT but not in MRT or CON (+11±5%, +7±7% and +2±4%, respectively, p =0.011). There was no change in 10m, 20m or 30m sprint performance in any group. HRT volume was 58±15% lower than that of MRT (p<0.001) and DOMS measured throughout training did not differ between groups (p=0.487). These findings suggest that one HRT session a week may be an efficient method for improving strength and power in ASP in-season with minimal DOMS.
