Effects Of Selected Aerobic Exercises On The Improvement Of Cardiorespiratory Parameters Of Male Middle Distance Athletes: The Case Of Ambo University Youth Athletics Project

Abstract

Cardiorespiratory endurance refers to the ability of the coronary heart and lungs to deliver oxygen to working muscle tissue during continuous physical activity, which is an important indicator of physical fitness. Many research studies show the effect of aerobic exercises on the improvement of male middle-distance athletes' cardiorespiratory parameters or Vo2 max, resting heart rate, and ventilator anaerobic threshold. These days, aerobic exercise is a good treatment to improve athletes' Vo2 max, resting heart rate and ventilator anaerobic threshold around the world. But now a day's there are no studies were done specifically in the area of aerobic exercise programs on cardiorespiratory parameters of male middle distance athletes of the Ambo University youth Athletics project. Based on the above reality, a researcher conducted a current study for improving the cardiorespiratory parameters of male middle distance athletes of the Ambo University youth athletics project. The primary purpose of this study was to examine the effects of selected aerobic exercise on the improvement of cardiorespiratory parameters of male middle-distance athletes. The study design was an experimental method, consisting of one experimental group, to improve cardiorespiratory parameters of the twelve (12) male middle-distance athletes of Ambo University youth athletics project, having age rank between 16-17 years old. Experimental subjects were participating in selected aerobic exercises for eight (8) weeks i.e., three (3) days per week and forty-five (45) minutes duration per day. Pre-test and post-tests were conducted on cardiorespiratory parameters such as Vo2 max, Resting Heart Rate, and BMI, test. The data collected from subjects was analyzed by paired sample t test and Pearson product-moment correlation coefficient to determine the differences between the pre-test and post-test mean value results of the subjects of the study. The study was designed in such a way that ethical issues have properly been addressed. Therefore, the results obtained from the study indicate that there were significant improvements in Athletes' Vo2 max (pretest 44.69,±4.944) and (posttest 49.83, ± 3.243) t (11) = -4.929, p = .000” or P < .001), RHR (pretest 69.17, ± 8.310)and (posttest of 62.08, ± 4.660) t (11) = 3.976, p = .002”), and BMI (pretest 18.1200, ± 1.43664) and (posttest 18.5833, ±1.56428)t (11) = -3.252, p = .008”). So, the findings of the study reveal different responsible bodies like coaches, Ambo University sports science department, and the Ambo city sports office should take considerable action for the improvement of Athletes' cardiorespiratory parameters for the University youth athletics projec
