Effect of Supervised Circuit Resistant Training (CRT) Program on Cardiorespiratory Endurance of Adolescents

The focus of the study was to apply for the supervised circuit resistant training (CRT) Program on cardiorespiratory functions of an adolescent having the same age, gender, and exercise schedule from the Department of Sports Sciences and Physical Education, Dera Ismail Khan. The subjects of the study were accordingly divided into two equal groups, where a was labeled as the Experimental Group (EG) and group B was named as the Control Group (CG). For this purpose, 20 subjects as an experimental group (EG) and subjects as a control group (CG) were selected. The experimental group was given a CRT protocol of eight-week to check the influence of exercise upon functions of cardiorespiratory, whereas the control group was given no treatment. The desired parameters were tested before and after the prescribed exercise protocol for the overall assessment of cardiorespiratory fitness. For this purpose, the researcher used the sphygmomanometer and spirometer to get the readings. The researcher collected the data from all the participants under the guidance of the research supervisor used for further evaluation. According to the analyzed data, the participants of an experimental group showed statistical significant differences in Hip Circumference (HP), Waist-hip ratio (WHR) and Body Mass Index (MBI), Furthermore, results of the test revealed a significant increase in the cardiorespiratory indices (CO, SV, IRV, ERV) among the participants' experimental group.
