Brief Summary:
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.

Detailed Description:

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.

Actual Enrollment : 29 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Supportive Care
Official Title: Immediate Effects of Post-isometric Relaxation and Static Stretching on Quadriceps Muscle During Vertical Jump in Volley Ball and Basketball Players
Actual Study Start Date : August 1, 2017
Actual Primary Completion Date : January 31, 2018
Actual Study Completion Date : February 28, 2018

Arm Intervention/treatment
Experimental: Muscle Energy Technique
Post isometric relaxation technique was used in experimental group
Other: Muscle Energy Technique
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

Active Comparator: Static Stretch
Static stretching was given in control group
Other: Static Stretch
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




Primary Outcome Measures :
  1. Vertical Jump - Force Plates [ Time Frame: 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

  2. Muscle Recruitment: through Electromyography [ Time Frame: Day 1 ]
    During vertical jump athletes quadriceps muscle recruitment is noted by noting the amplitude

  3. 30 Meter sprint [ Time Frame: Day 1 ]
    Athletes start its 30 meter sprint with maximum speed and it is used to check the maximum strength in seconds

  4. Ground Reaction force (flight time):- through Force plates [ Time Frame: 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
