TRIAL DESCRIPTION
Public title Comparing effects of plyometrics, closed kinetic chain and quadratus lumborum strengthening exercises on vertical jump.
Official scientific title Comparing effects of plyometrics, closed kinetic chain and quadratus lumborum strengthening exercises on vertical jump
Brief summary describing the background and objectives of the trial Plyometrics refers to exercises that are designed to enhance muscle, mainly through the use of jump training. Plyometric exercises constitute a natural part of most sport movements because they involve jumping, hopping, and skipping (i.e., such as high jumping, throwing, or kicking) auseexplosive leg power is a key ingredient to maximize vertical jump performance, CKC exercise refers to any exercise where the limb is trained against an immobile surface e.g. squat exercise ,there is high positive correlation between jumping and leg muscle strength for CKC compared with open kinetic chain (OKC ) and those finding is true for vertical and long jump. Essentially the quadratus lumborum controbutes to the stablization and movement of the spine and pelvic, Core stability is the ability of the lumbopelvic hip complex to prevent buckling and to return to equilibrium after perturbation. There is a clear relationship between trunk muscle activity and lower extremity movement. Current evidence suggests that decreased core stability may predispose to injury and that appropriate training may reduce injury

INTERVENTIONS
Intervention type Intervention name Dose Duration Intervention description Group size Nature of control
Experimental Group plyometrics 3times/week 6weeks • Counter Movement Jump (CMJ) — the athlete starts in a standing position, and squats down to the 90 degree leg bend position before immediately jumping up. Hands remain on hips. • It will be conducted with the use of arm swing action, performing the CMJ with an arm swing action has shown to increase performance by 10 % or more (Klavora P, 2000). 10
Experimental Group closed kinetic chain 3times/week 6 weeks For the CKC regime, two exercises will be used: 1. With their hands placed firmly on a stable surface, subjects were asked to stand fully on one leg, with the other leg flexed to 90 degree at the knee, They then have to squat down to approximately 20 degree and hold this position for four seconds. They then will return to their initial stance for a four second rest period. This will be repeated until the first signs of fatigue. They then will swap their legs and repeat the exercise (Khoshkhoo et al., 2016). 10
Experimental Group quadratus lumborum strength 3times/ week 6 weeks Concentric active resisted exercise program (low repetition high resistance) against weight will be used and modified according to the subject’ individual quadratus lumborum strength. It will be done low repetition performing 5-7 repetition maximum (RM) performed at moderate contraction velocity (1-2 second) for four sets of each exercise with three mint rest between sets and exercise , three time per week for six weeks ( Jenny et al., 2017). 10
Control Group no no no no 10 Placebo
