Abstract

Introduction: In team sports with short repeated sprints and changes of direction, it is important to know how the anaerobic capacity level of his players is and develops during the season. To test this ability the 15m Modified Shuttle Run Test (15m MSRT), based on the Wingate Cycle Test principles, was developed. Method: Two groups of five female soccer players from Germany (GER) (average age 19.2 years; range 18–21) and the United States of America (US), (average age 18.8 years; range 17–21) performed a 15m MSRT on two occasions to test the reliability. Maximum (Highest Lap Velocity (HLV)), minimum (Lowest Lap Velocity (LLV)) and average speed (Mean (Individual) Velocity (M(I)V)) of the individual player and average lap speed (Mean Lap Velocity (M(L)V)), the Fitness Index (FiI), Fatigue Index (FaI) and Speed–Endurance– Index (SEI) was calculated for the individual player as well as for the whole team. Results: The ICC and CV for the MLV was 0.95 and 1.41% resp (GER) and 0.72 and 3.24% (US), the Fitness Index (GER: 0.93 and 2.90%; USA: 0.78 and 4%) and Speed– Endurance–Index (GER: 0.95and 3.30%; US: 0.94 and 4.40%) Conclusion and recommendation: The 15m MSRT is a reliable tool to assess and monitor both individual and team running speed. The MIV is useful to individualize anaerobic capacity training
