Relationships between Sprint Ability and Endurance Capacity in Soccer Referees

Abstract

[EN] The aim of this study was to analyze the association between sprint ability and endurance capacity in soccer referees. Twenty-three Spanish officials participated in this study. Each referee undertook, in this order, a 40 m linear straight sprinting test (40 m Sprint) and the Yo–Yo intermittent recovery level 1 test (YYIR1) interspersed with a 8 min of self-administered rest. The results in the 40m Sprint test showed that the time spent by referees was 5.56 0.27 s and achieved a maximum velocity of 31.46 2.85 km hð€€€1. Furthermore, during the YYIR1 the referees covered 1213.91 432.26 m. The distance covered at YYIR1 was moderately correlated to the velocity achieved in the 40 m Sprint test (r = ð€€€0.404, p < 0.05). These results suggest that the ability to reach high speeds is a limiting factor in YYIR1 performance.
