Comparison of Muscle Energy Technique vs Static Stretch in Vertical Jump of Basketball and Volleyball Player
Immediate Effects of Post-isometric Relaxation and Static Stretching on Quadriceps Muscle During Vertical Jump in Volley Ball and Basketball Players
調査の概要
詳細な説明
Vertical jump is defined as the ability of athlete to elevate off the ground from standstill.There are two types of vertical jump which re squat vertical jump and vertical stop jump. There was a strong correlation between maximal strength in half squats and sprint performance and jumping height.
Muscle energy technique(METS) is the procedure which involves voluntary contraction of muscle in specific direction with different angles against a counterforce applied by clincian.METS is used to enhance strength of group of muscle, increase afferent input to facilitate reflexive stabilization and increase endurance in coordinated movement patterns.
Athletes perform dynamic stretching before sports involvement. Study shows that three 30 seconds stretch enhance muscle length immediatley after stretching.
A study conducted in 2003 to see the effects of muscle energy technique on hamstring extensibility, the conclusion of this study that muscle energy technique produced an immediate increase in passive knee extension.
A study conducted on immediate effect of two muscle energy techniques on quadriceps muscle during vertical jump. The study suggests concentric muscle energy technique on quadriceps muscle is the most appropriate technique to potentiate height jump performance and stretch-shorten cycle function in counter-movement jump.
Athletes ususully perfrom stretching exercises in warm up before involvement to sports.Study suggest that dynamic stretching is more suitable for use as part of warmup in young athletes. Athletes invlve in high intensity exercise demand stretch shorten cycle, stretching may be important for injury prevention. Stretching also reduce the peak torque and mean power output.

実験的：Muscle Energy Technique
Post isometric relaxation technique was used in experimental group
|
In experimental group, post-isometric relaxation technique has given to the athletes.
The position of athlete was prone and the involved group of muscle was quadriceps.
Firstly end range of the quadriceps muscle group assess and guide the athlete to put 20% of their maximum voluntary contraction and physiotherapist resist the athlete and isometric contraction of quadriceps remain for 6-10 seconds

アクティブコンパレータ：Static Stretch
Static stretching was given in control group
|
Control group has treated with static stretching after the pre-assessment that includes three repetitions with duration of fifteen seconds with twenty second rest intervals on lower extremities
