EFFECT OF AEROBIC AND COMPLEX TRAINING ON PHYSIOLOGICAL VARIABLES OF FOOTBALL PLAYERS *Mr. D.N. Rayar Rozario., Research Scholar, Department of Physical Education Bharathiar University, Coimbatore *Dr. V. Vallimurugan, Ph.D., Assistant Professor, Department of Physical Education Bharathiar University, Coimbatore Abstract The purpose of the study was to find out effect of Aerobic and Complex training on selected physiological variables of Resting heart rate and Vital capacity of football players. It was hypothesized that aerobic and complex training may have significant effect on selected physiological variables of football players. The subject for this study were selected by purposive sampling of 45 male football players from Madurai Kamaraj University, their ages ranged between 18-22 yrs. Out of 45 subjects 30 subjects had been kept in experimental groups i.e. aerobic training composed of 15 subjects, complex training having 15 subjects and rest of i.e. 15 subject were kept in control group. For the study pre-test, post test randomized group design was used in which the pretest was taken prior to the Aerobic and Complex training (football specific) and post test was taken after twelve weeks aerobic and complex training (football specific). The data were analyzed by applying descriptive statistical and analysis of co-variance (ANCOVA). The level of significance was set at 0.05. In the light of the findings, it is concluded that, there is significant difference in the Vital capacity of foot ball players due to the twelve weeks Aerobic and Complex Training. Further, there is significant difference in the Resting heart rate foot ball players due to the twelve weeks Aerobic and complex Training. KEY WORD- Aerobic, Complex, Vital capacity, resting heart rate INTRODUCTION Heart rate monitor with a wrist receiver heart rate is measured by finding the pulse of the heart. This pulse rate can be found at any point on the body where the artery's pulsation is transmitted to the surface by pressuring it with the index and middle fingers; often it is compressed against an underlying structure like bone. The thumb should not be used for measuring another person's heart rate, as its strong pulse may interfere with the correct perception of the target pulse. The radial artery is the easiest to use to check the heart rate. However, in emergency situations the most reliable arteries to measure heart rate are carotid arteries. This is important mainly in patients with atrial fibrillation, in whom heart beats are irregular and stroke volume is largely different from one beat to another. In those beats following a shorter diastolic interval left ventricle doesn't fill properly, stroke volume is lower and pulse wave is not strong enough to be detected by palpation on a distal artery like the radial artery. It can be detected, however, by doppler. The International journal of analytical and experimental modal analysis Volume XII, Issue V, May/ 2020 ISSN NO:0886-9367 Page No:404
