摘要:Objectives: To investigate the effect of two hamstring training protocols on eccentric peaktorque before and after soccer specific fatigue.Participants: Twenty-two university male soccer players.Design: Isokinetic strength tests were performed at 60°/s pre and post fatigue, before andafter 2 different training interventions. A 45-minute soccer specific fatigue modified BEASTprotocol (M-BEAST) was used to induce fatigue. Players were randomly assigned to a 4 weekhamstrings conditioning intervention with either a maximum strength (STR) or a muscleendurance (END) emphasis.Main outcome measures: The following parameters were evaluated:– Eccentric peak torque(EccPT), angle of peak torque (APT), and angle specific torques at knee joint angles of 10°,20°, 30°, 40°, 50°, 60°, 70°, 80° and 90°.Results: There was a significant effect of the M-BEAST on the Eccentric torque angle profilebefore training as well as significant improvements in post-fatigue torque angle profilefollowing the effects of both strength and muscle endurance interventions.Conclusions: Forty-five minutes of simulated soccer activity leads to reduced eccentrichamstring torque at longer muscle lengths. Short-term conditioning programs (4-weeks) with either a maximum strength or a muscular endurance emphasis can equally reduce fatigueinduced loss of strength over this time period.
