Brief Summary: Background Muscle flexibility is a fundamental physical quality for body development daily life and sports activities and also for maintaining muscle quality during aging Limited flexibility leads to an increased prevalence of musculoskeletal injury in general population and longer return to sports activities

Among the existent strategies to increase muscle flexibility in sports training and physical rehabilitation static stretching is commonly used by health and physical activity professionals Its effectiveness in increasing flexibility has been widely demonstrated however its effects on muscle strength and power remains controversial

Therefore eccentric resistance exercise has been proposed as an effective intervention for increasing muscle flexibility through structural changes on muscle architecture pennation angle and fascicle length with the additional benefit of resistance training on muscle strength and power Nonetheless its unknown if the increase in muscle flexibility through eccentric resistance exercise could be similar to what has been previously demonstrated with static stretching
Detailed Description: Hypothesis The increase in hamstring flexibility after 6 weeks of eccentric resistance training in young males would be similar compared to 6 weeks static stretching training in the same population

Goals The primary aim of the study is to compare the effectiveness of 6 weeks eccentric resistance training vs 6 weeks static stretching training on hamstring flexibility in young males

Specific Goals Determine the effect of 6 weeks excentric exercise training and 6 weeks static stretching training on unilateral maximal isometric voluntary strength between both groups

To compare the effect of 6 weeks excentric exercise training and 6 weeks static stretching training in structural changes on muscle architecture pennation angle fascicle length and muscle thickness

Methodology

Study design Forty two young males between 18 and 35 years will be divided into three groups hamstring eccentric resistance training group EEG n14 hamstring static stretching group SSG n14 and control group CG n14 Volunteers of eccentric resistance training group will be subjected to 6 weeks of Nordic hamstring exercise 3xwk while volunteers of static stretching group will be subjected to 6 weeks of hamstring passive static stretching 3xwk Control group will not attend any type of intervention Before and after 6 weeks of training Knee Extension Angle and Sit and Reach test will be performed for measuring hamstring flexibility Unilateral Hamstring Isometric Maximal Voluntary Strength will be determined by load cell force transducer and pennation angle fascicle length and muscle thickness of Long Head Biceps Femoris will be conducted through muscle ultrasonography

Study parametersendpoint

The main study endpoint is the increase in hamstring flexibility assessed with Knee Extension Angle and Sit and Reach Test

Secondary endpoints include Unilateral Hamstring Isometric Maximal Voluntary Strength IMVS and Architectural changes in Long Head Biceps Femoris muscle

Other parameters include age body weight body height body mass index BMI level of physical activity

Expected results With the proposed project the investigators expect that eccentric exercise training will increase hamstring muscle flexibility at similar level compared with static stretching training The findings will define the potential of eccentric exercise training on muscle flexibility in healthy participants These results could expand the benefits of this type of exercise training focused on being included in populations with limited mobility such as elderly and injured populations
