Summary

The purpose of this study was to investigate effects of different strengthening methods on hamstring muscle group's passive mechanical properties and to investigate this effect's relation with performance changes in healthy individuals. 42 healthy sedentary male participated in this study. Passive mechanical properties and strength of hamstring and quadriceps muscles, flexibility of hamstring muscles, anaerobic explosive strength, reaction time, agility were measured. Participants randomized evenly into one of three groups; eccentric, concentric and neuromuscular electrical stimulation (NMES). After 8 weeks training period, participants were measured again.

Interventions

OTHER

Concentric Exercise

Leg Curl Machine: 1st week - 1st day is 10 maximum repeat test. 2nd week - 2 days of training - 2 sets of 6 repeats. %60 percent of maximum load. 3rd week - 3 days of training - 3 sets of 6-8 repeats. %60-80 of maximum load. 4th-8th week - 3 days of training - 3 sets of 8-12 repeats. when 3 sets of 12 achieved, load was increased with 2.5kg.

OTHER

Nordic Eccentric exercise

1. st week - 1 day - 2 sets of 5 repeats. 2. nd week - 2 days - 2 sets of 6 repeats. 3. rd week - 3 days - 3 sets of 6-8 repeats. 4. th week - 3 days - 3 sets of 8-10 repeats. 5-8th weeks - 3 days - 3 sets of 12-8 repeats. When achieved 3 sets of 12 repeats with full range, speed was increased.

OTHER
