Brief Summary  

INTRODUCTION

Volleyball is a sport where two teams face each other on a pitch separated by a central net, trying to pass the ball over the net to the ground of the opposing field. Each team has a limited number of touches to return the ball to the opposite field. (1)Usually, the ball is hit with hands and arms, but also with any other part of the body according to the game situations. Each of the players must rotate their positions as they get points. It is a complex discipline sport with high technical, tactical, and athletic demands on the players. Serving, passing, and setting the ball are accompanied with spiking or attacking actions. Jump rope training was previously reported to be effective in increasing fitness and muscular function of the involved extremities; and improving cardiovascular functions and physical fitness. This training requires the coordination of several muscle groups to sustain precisely timed and rhythmic plyometric movements, in order to be able to involve a high-intensity concentric contraction immediately after a rapid and powerful eccentric contraction. Since the rope has been considered a safe, inexpensive and portable tool, jump rope training has been preferred for adolescent population (2)

The jump rope has been a major training tool for many sports such as boxing, wrestling, tennis, and martial arts. Lately, it has also become popular with volleyball players among many training options. (3)Jumping rope requires the coordination of several muscle groups to sustain the precisely timed and rhythmic movements that are integral to the exercise. The coordination of these muscle groups increases an athlete’s capacity for dynamic balance. Jumping rope can also be used to develop the coordination of neuromuscular skills, muscle strength, and cardiovascular endurance. It burns calories and builds strength in the upper and lower body. Movements that occur during regular rope jumping primarily include movements of the ankle, knee, hip, and shoulder joints. Upper extremity conditioning might be as important as lower extremity conditioning in jumping rope. (1)Jumping rope involves a ballistic “catapult” or “slingshot” action of the upper extremities encountered in throwing events and also involves grasping relatively light implements for long periods of time, under isometric or static conditions of a submaximal nature. During a whole cycle of jumping, the shoulder undergoes rotational movement with elevation. By the time of the preparatory phase, the shoulders hyperextend and the elbows are in full extension. (4)During the propulsive phase the opposite motions occur, and the shoulders rotate at about 90° to 100° elevation with slightly flexed elbows, and then the arms go down toward the ground and around in circles placing larger loads on the shoulder muscles. Furthermore, using weighted ropes may have additional advantages that are typically associated with core plyometrics. (5)The effects of rope training on shoulder strength are not yet well known. It is also unknown whether a weighted jump rope has any additional effects in comparison with unweighted ones and controls with no jump-rope training.Weighted jump rope training has been suggested to be another choice, since using weighted ropes allow combining the loading principle of exercise with standard jump rope training (6). Also, the use of weighted ropes may also have additional advantages that are typically associated with plyometrics, such as improving upper-body strength and coordination for lower-body (7). A recent systematic review and meta-analysis revealed that plyometric training programs have only small to medium-sized effects to improve measures of physical fitness and athletic performance, whereas complex training programs have predominantly larger effects.

NEED FOR STUDY

 It is desirable to have a strong offense, smash, or spike to achieve success in this sport.Starting with an approach followed by a vertical jump, one of the objectives in volleyball is to spike, aiming to hit the ball at the highest possible speed.Jumping rope requires the coordination of several muscle groups to sustain the precisely timed and rhythmic movements that are integral to the exercise. The coordination of these muscle groups increases an athlete’s capacity for dynamic balance. Movements that occur during regular rope jumping primarily include movements of the ankle, knee, hip, and shoulder joints. Upper extremity conditioning might be as important as lower extremity conditioning in jumping rope.Thus, need for the present study is to evaluate effect of resisted jump rope training programme on shoulder explosive power & vertical jump height in amateur volleyball players.

RESEARCH QUESTION

 Will there will be any effect of resisted jump rope training programme on shoulder explosive power and vertical jump height in amateur volleyball players?

 Study Design:  Randomized controlled trial

 Sample size: 40 (Open EPI)

  Sampling Method: Simple random sampling

 Study Duration: 2 years

•        Equipment’s to be used

       Resisted Rope

•        Materials to be used:

       Consent form

         Assessment sheet

            PAR Q+

        Amateur Males and female volleyball players

         Age group 18 to 25 years.

Participants who are willing to participate.

Participants fulfilling PAR Q+

 

Exclusion Criteria

 Any type of systemic illness.

 Psychological unstable player

 Any recent surgical and medical history.

PROCEDURE

Protocol is prepared and Ethical Clearance will be obtained from IEC at Dr. APJ Abdul Kalam College of Physiotherapy.

The participants will be selected on the basis of eligibility criteria.

Informed consent will be obtained from the participants and demographic data will be recorded. Participants will be given PAR Q+ questionnaire to fill, to determine the safety and possible risk of exercising based on the history of the health.

Participants will be allocated into 2 groups. Group A (experimental group n= 20) and Group B (control group n=20).

Prior assessment of the participants will be done using Vertical Jump Test for Vertical Jump Height ,and Medicine Ball Throw Test for Shoulder Explosive Power.

For 6 weeks participants will be given intervention thrice a week.

Statistical analysis will be done and result will be calculated.
