Strengthening Effect on Hamstring's Passive Mechanical Properties

Effects Of Different Strengthening Methods On Hamstring Muscle Group's Passive Mechanical Properties in Healthy Individuals

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.

Inclusion Criteria:

• being sedentary

Exclusion Criteria:

• Having knee, hip and/or back pain
• Having a cardiovascular condition/disease
• History of previous knee and/or hip surgery
• Having a diagnose of any systemic disease
• History of previous hamstring injury
• Being physically active within last year ( Regular activity at least 3 days a week and continuity of at least 2 months was accepted as being physically active)
