Background

There are many factor that contribute or detract from performance -- physiology ,psychology,

skills, tactics, equipment, and environment. Balance ,a motor skill, is the of ability to maintain

center of gravity over the base of support. Factor that influence balance include sensory

information obtained from the somato-sensory , visual, and vestibular system and motor response

that affect coordination , joint range of motion(ROM) , and strength. Each sport likely requires

different level of sensori-motor processes to perform skills and protect the neuromuscular system

from injury.

RESEARCH QUESTION

Does the influence of plyometrics combined with CKC on balance more effective than

PROPERIO with CKC, and CKC training ?

AIM OF THE STUDY

1. To see the effect of combination of plyometrics with CKC, proprioception with CKC and

only CKC on static and dynamic balance of lower limb.

2. To find out which exercise is the best in improving balance.

HYPOTHESIS

Experimental hypothesis

Plyometrics training is more effective than proprioception and CKC training in

improving static and dynamic balance of lower limb







88

Null hypothesis

Plyometrics training is not more effective than proprioception and CKC training in

improving static and dynamic balance of lower limb.

NEED FOR THE STUDY

Balance is a skill which is an essential element for participation in sports. An athlete’s

performance depends on good balance. Different types of exercises are used to improve the

balance. It is known that exercises like Plyometrics, Proprio and CKC, individually & in

combination, are used to improve balance but it is not known which combination is most

effective for improving balance. Therefore, this study aims to compare the combinations of

exercises.

METHODOLOGY

SAMPLE

30 female were initially recruited, out of which 9 were withdrawn due to various reasons. 21

hostlers females with mean age 22±1.97.

SELECTION CRITERIA

INCLUSION CRITERIA

1. Subject of age 19 – 25 year are taken as subject.

2. Subject who have not been involved in the any kind of drills during course of period.

3. Subject who could not qualify single leg stance test

EXCLUSION CRITERIA

1. Any present history of trauma of ankle, hip and knee for last 6 month.

2. History of any dizziness or consciousness.

3. History of any visual, auditory or systemic deficit.

4. Subject not willing to participate in training program

5. Any nervous system problem.

6. History of any marked muscle pain.

DESIGN

DATA ANALYSIS

The one way annova has been done for comparing the pre-treatment (0 sessions) of static

and dynamic balance. Than comparison between the three groups A, B and C for the

post value of the 8 direction of SEBT and SLST.

Post hoc Scheffe’s test has been done for comparing of (0-8) session mean difference

for Group between A and B, A and C and B and C.

Paired t test- has been performed to compare within the pre and post value of A , B

and C GROUP.

Significance level has been selected as 0.05.

They are most active in the end of range of motion (Arnhem and prentice, 2000)

b) According to prentice 1999, plyometrics is defined as a quick, powerful movement involving

pre-stretching the muscle and activating the stretch the stretch- shortening cycle to produce a

subsequently strong concentering contraction.

The main purpose of plyometric training is to heighten the excitability of the nervous system for

improved reactive ability of the neuromuscular system.

c) The proprioceptive stretch reflex is another mechanism by which force can be produced

during the stretch – shortening cycle.

Mechanoreceptor located with in the muscle provide information about the degree of muscular

stretch.

This information is transmitted to the central nervous system and become capable of influencing

muscle tone, motor execution program and kinesthesia awareness.

LIMITATION OF THE STUDY

1. This study utilized a relatively young sample and only girls. Therefore, results and conclusion

from this study are most applicable to a similar age group and sex.

2. In this study, the individual specificity of leg length is not taken which can affect the reach

distance of the subject.

3. Athletes are not included in study. Including athletes in the study would have made it possible

to generalize the results in sports population.

SCOPE OF FUTURE RESERCH

1. Future research should examine the effect of the other type of combination exercises on the

other age group.

2. It can be done on top level athlete in different sports and different age groups to see the

result.

3. This can be done with male athletes and compare with female athletes.

4. Duration of the study can be increased.

CLINICAL SIGNIFICANCE OF THE STUDY

1. Balance is a skill which is used to improving athletic performance.

2. It will be also decrease the risk of re-injury.

3. Balance is used in the rehabilitation of the patients.

Conclusion

This result show that combination of Plyometrics + Closed Kinetic Chain Exercise (Group A)

prove to be most effective in improving static and dynamic balance than combination of

Proprioception + Closed Kinetic Chain Exercise (Group B) and only Closed Kinetic Chain

Exercise (Group C).
