The aim of this study was to compare the effects of two anaerobic training regimes on highintensity intermittent exercise performance evaluated by the Yo -Yo Intermittent Recovery Test level 1 (YYIR1) and 2 (YYIR2). During a 8-12-wks in-season period, nineteen sub-elite soccer players (age 24±5 years, height 177±7 cm, body mass 75±5 kg) performed either repeated sprint (RS; n=9) or speed endurance production (SEP; n=10) training twice a wk. RS training consisted of 2-4 sets of 6x5-s sprints followed by 10-15 s of passive recovery, whereas SEP training was characterized by 6-8x20-s all-out efforts interspersed with 120 s of passive recovery. After the training period, both RS and SEP group improved significantly YYIR1 (RS: 2236 vs 2480 m; SEP: 2248 vs 2580 m; p<0.001) and YYIR2 (RS: 911 vs 1078 m; SEP: 904 vs 976 m; p<0.01) performance. According to a statistical approach based on the magnitude of change, RS induced possibly greater changes in YYIR2 performance than SEP, whereas differences in YYIR1 changes were unclear. Thus, the present results show that high-intensity intermittent performance was improved after both RS and SEP training.

Abstract

The aim of this study was to compare the effects of two anaerobic training regimes on highintensity intermittent exercise performance evaluated by the Yo -Yo Intermittent Recovery Test level 1 (YYIR1) and 2 (YYIR2). During a 8-12-wks in-season period, nineteen sub-elite soccer players (age 24±5 years, height 177±7 cm, body mass 75±5 kg) performed either repeated sprint (RS; n=9) or speed endurance production (SEP; n=10) training twice a wk. RS training consisted of 2-4 sets of 6x5-s sprints followed by 10-15 s of passive recovery, whereas SEP training was characterized by 6-8x20-s all-out efforts interspersed with 120 s of passive recovery. After the training period, both RS and SEP group improved significantly YYIR1 (RS: 2236 vs 2480 m; SEP: 2248 vs 2580 m; p<0.001) and YYIR2 (RS: 911 vs 1078 m; SEP: 904 vs 976 m; p<0.01) performance. According to a statistical approach based on the magnitude of change, RS induced possibly greater changes in YYIR2 performance than SEP, whereas differences in YYIR1 changes were unclear. Thus, the present results show that high-intensity intermittent performance was improved after both RS and SEP training. However, in contrast to the YYIR1, where no differences were observed between the groups, in YYIR2, the RS training-induced changes seem to be possibly greater compared to SEP. A plausible explanation could be that the RS protocol induced a higher improvement in the anaerobic energy system, which is taxed to a larger extent during the YYIR2.
