Effect of Exercise on Aerobic Fitness of Young Male Adult

ABSTRACT The main aim of this study was to determine the effect of exercise on aerobic fitness of young male adult. Twenty (20) subjects were used for this study comprising ten (10) experimental and ten (10) control, with age range of 18-25 years. They were undergraduate of Ladoke Akintola Univerty of Technology who were randomly selected to participate in the study. None of them smoke cigarette nor ingest caffeine. They were free from cardiovascular and respiratory diseases. All the subjects signed an informed consent prior to the study to determine eligibility to participate in the research study. Upon arrival of the subject in the laboratory they were made to sit down for 10 minutes, so that their heart rate and blood pressure will come back to the resting level Pretest measurement were made on heart rate, blood pressure, max VO, and age, weight, height were determine and recorded in all the subjects. Maximal oxygen uptake was measured by heart rate method using the formula 111.33- (0.42 Heart rate) (America College of Sport Medicines, 2014). The subjects were divided into experimental and control group. The experimental group subjects were exercised for eight (8) weeks, three (3) times a week at an intensity of exercise of about 60% maxVO2. The control subjects did not exercise at all. At the end of eight (8) weeks, post-test similar to pretest were conducted on them. v The result of the test were used to compare both experimental and control group. The study revealed that exercise increase maximal oxygen uptake and lower heart rate at rest which signify maximal aerobic power in the experimental subject compared with control. The implication of this study shows that regular and intense exercise of about 60% maxVO2, prevent respiratory abnormality like asthma, dyspnoea, hunting behavior of the respiratory control, and hyperpnoea. More reseach is needed in this area of study using greater number of subject at an intensity of about 70% max vo2, three (3) times a week, for a duration of about six (6) month or more to allow for generalization of result
