Ng, Zi Ru (2022) Comparison between effect of lower limb cyclic stretching and ballistic stretching in jumping distance among undergraduate students: a comparative study. Final Year Project, UTAR.
Abstract
Background and Objective: The horizontal jump distance is a useful tool for evaluating an athlete's sports performance and leg strength, and it is used in the training of several sports that call on the ability to jump horizontally. Studies have shown that stretching before exercise can improve power, which is a crucial component of many sorts of physical activities, including jumping. Thus, this research will be studying the effect of lower limb stretching on sports performance using horizontal jump. This research is aimed to compare the effect of lower limb cyclic stretching (CS) and ballistic stretching (BS) in sports performance by comparing the effect of lower limb cyclic stretching and ballistic stretching in the jumping distance among undergraduate students using the standing broad jump test. Methods: This was a randomized, two-armed, parallel-group quasiexperimental study. The targeted population was undergraduate students in UTAR, Sungai Long Campus and the sample size was calculated to be 42 students. Eligible participants were allocated into two intervention groups randomly which were CS and BS. Each participant visited the physiotherapy center to complete the pre-test, intervention and post-test. Each participant was assessed in one day from pre-test to post-test. Both stretching protocols consisted of three lower limb stretches which are mainly for the iliopsoas, hamstring muscles, and gastrocnemius. Results: The total participants recruited were 44 students which consisted of 22 participants in the CS group and 22 participants in the BS group. The mean age is 20.55±1.06 in the CS group and 19.73±1.20 in the BS group. No significant difference was detected between the pre-stretching and post-stretching jumping distance in the CS group with MD=-1.22cm, p>0.05. Moreover, there was also no significant difference between the pre-stretching and post-stretching jumping distance in the BS group with MD=-0.06cm, p>0.05. When comparing the significant difference between the effect of lower limb CS and BS in jumping distance, the results showed MD= -1.16cm, p>0.05. Conclusion: The lower limb CS has no significant effect in the jumping distance among undergraduate students using the standing broad jump test; the lower limb BS has no significant effect in the jumping distance among undergraduate students using the standing broad jump test. There is no significant difference between the effect of lower limb CS and BS in jumping distance.
