简要总结
A randomized control trial study was conducted in Islamic International University Islamabad from 1st August 2017 to 31st January 2018 according to the set criteria. A total number of 29 athletes age between 18-35 and playing as part time/ domestic level included in this study. Data were divided into experimental group (n=15) and control group (n=14) by random sampling technique. Post isometric relaxation technique was used in experimental group and static stretching was given in control group. Baseline reading was taken before intervention and post intervention reading taken immediately after application of intervention. Data analyzed through SPSS 20.
详细描述
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.

结局指标
主要结局
Vertical Jump - Force Plates
时间窗: Day 1
Athletes starting position is squat position (Which is the baseline position) on the force-plates and did jump by saying jump, then Jump and sway were noted by physical therapist in seconds
Muscle Recruitment: through Electromyography
时间窗: Day 1
During vertical jump athletes quadriceps muscle recruitment is noted by noting the amplitude
30 Meter sprint
时间窗: Day 1
Athletes start its 30 meter sprint with maximum speed and it is used to check the maximum strength in seconds
Ground Reaction force (flight time):- through Force plates
时间窗: Day 1
Athletes starting position is squat position on the force-plates and did jump by saying jump and the flight time were noted by physical therapist in newton
