International Journal of Scientific and Research Publications, Volume 2, Issue 6, June <strong>2012</strong> 30 ISSN 2250-3153 The Correlational Study of the Vertical Jump Test and Wingate Cycle Test as a Method to Assess Anaerobic Power in High School Basketball Players Abstract- Basketball is a prime example of a sport that predominantly utilizes anaerobic metabolism. The Wingate cycle and vertical jump tests have been used to assess anaerobic power in athletes for the purpose of providing information of anaerobic performance in a given sports. The lack of research in the field of more sport specific tests to assess anaerobic performance has lead to the development of the present proposed investigation. Aims & Objectives: A study to correlate the vertical jump test and wingate cycle test as a method to assess anaerobic power in high school basketball players. Materials & Methods: A correlational study was conducted on 100 high school basketball players between the age group of 14- 18 years (15.6000 ± 1.14286 (SD)) was included from various sprts institutes of Rajkot. Subjects were selected by simple random sampling techniques. On the first day, anthropometric measurements and the vertical jump test were performed. Peak and mean anaerobic power were determined using equations based on each subject‘s individual vertical jump height in centimeters (cm), body mass in kilograms (kg), and height in centimeters (cm). On the second day, the subjects were performed the 30-second Wingate cycle ergometer test. Peak and mean anaerobic power over the 30-seconds, were calculated by a computer program during the test. Results: Data were analyzed by Pearson Correlation coefficient which showed significant positive correlation between average power (r = 0.970, p > 0.05) & peak power of vertical jump test and Wingate test (r = 0.263, p > 0.05), demonstrating the validity of the vertical jump as a field test of anaerobic power. Conclusion: The result suggested that vertical jump tests may be accept as field measures of anaerobic power in high school basketball players.

INTRODUCTION naerobic power, or anaerobic fitness, represents a local characteristic of a muscle that exists independent of blood and oxygen supply to that muscle. 1 It is the ability of the body‘s musculature to generate significant amounts of power is considered to be a strong predictor of athletic success. 2 Currently anaerobic power tests are implemented in both clinical and field settings and assess an athlete‘s capability to produce both power Purvi K.

Functional movements, such as jumping and sprinting, are significantly related to playing time and performance in basketball. 3,4 Therefore, it seems logical that testing procedures that incorporate anaerobic power and sports specific movements would provide a valuable tool to assess and monitor components of basketball performance. 3 To date, numerous tests have been used in an attempt to successfully measure anaerobic power and output in basketball players, however no particular test has gained acceptance as a standard measure of anaerobic power in basketball players. 3 The Wingate cycle and vertical jump tests have been commonly used tests to assess anaerobic power in athletes for the purpose of providing vital information regarding anaerobic performance of athletes in a given sports. 5,6 The Wingate anaerobic test on a cycle ergometer has been used in laboratory settings both as an assessment of anaerobic performance and as a means to analyze physiological responses to supramaximal exercise. 6 The test was designed to be simple to administer; non-invasive; intended to measure muscle performance; 6 safe to assume that peak power which is a reflection of the ability of either the arms or the legs to produce high amounts of mechanical power and mean power reflects the endurance of the muscle groups involved in the test, 3 but the major drawback of it is expensive method and require equipment which is not feasible for administration to a wide variety of population. The most common field test which is used is the vertical jump test to evaluate anaerobic fitness improvements. It has been stated the vertical jump test is a more true power test used to measure both vertical jumping distance and power output. 3 The height that is achieved on the vertical jump has a direct correlation with the amount of force that is produced by muscle fibers. 7 During the vertical jump, total jump height and peak power can be measured and the mechanical work performed to accomplish the jump could be determined by using the distance that was measured. 5 Compare to wingate cycle ergometer test, this test is inexpensive, easy to aseess and equipment is also not needed, so we can easily use it as a field test. www.ijsrp.org
