| Popis: | The aim of this study was to investigate the relationship between aerobic endurance and linear speed on repeat sprint ability performance in female international footballers. Twenty-five female international football players completed 10-m, 20-m, 30-m linear speed, repeat sprint ability (RSA) and yo-yo intermittent recovery, level 1 tests. Pearson's product correlation (r) was used to assess the relationship between 10-m, 20-m and 30-m sprint times (S10-m, S20-m, S30-m) sprint time on the first trial of the repeated sprint test (RST1) and yo – yo intermittent recovery test, level 1 (YYIR1) with total repeated sprint time (RSTT). Linear regressions were used to describe the relationship between the dependent variable (RSTT) and independent variables (S10-m, S20-m, S30-m, RST1 and YYIR1). Pearson's correlation analysis indicated a large negative correlation between RSTT and YYIR1 performance (r = -0.58, P = .002), a very large significant relationship was established between S10-m and S20-m whilst an almost perfect relationship was present for S30-m and RST1. The results of the linear regression proved the independent variable RST1 explained 85% (adjusted R2) of the variation in RSTT scores. S10-m, S20-m and S30-m performance accounted for 62 – 83% of the variation in RSTT scores whilst YYIR1 performance only accounted for 33.6%. The results of this study indicate that fast linear speed can positively impact on RSTT performance whilst reduced aerobic endurance capabilities may negatively influence RSTT performance in female international footballers. |
