This study assessed the effects of eight (8) weeks Cardio Exercise on forced expiratory volume (FEV1) of overweight male adolescents in Yadin Garun Kurama, Kaduna State, Nigeria. Twenty eight (28) male adolescents were selected from the total population of 87 students. The participants were selected based on the inclusion and exclusion criteria 2 2 which included BMI between 25.0 kg/m and 29.9kg/m , male adolescents whose ages were between 10 and 13 years old and had no underlying health risk factors that will aggravate their participation in the training programme. Anthropometric and pulmonaryth measurements were taken at baseline and after the 8 week of training that is post-test. Quasi-experimental research design was used for this study. The Spiro bank G device by MIR, Roma, Italy was used to measure the force expiratory volume. Borg's rating scale was used to monitor the perceived intensity of the training programme. Data were analysed using SPSS software (version 21). The descriptive statistics of means, standard deviation, and standard error of means were used to analyze the physical characteristics (age, weight, height, and BMI) and raw data of the variables. t-test was used to analyze the effect of the training programme on the variables. An alpha level of 0.05 was used for all statistical analyses. The results of the study showed significant improvement in forced expiratory volume in one second (FEV1) (19.01%) following eight weeks of jogging. It was recommended that adolescents should be encouraged to participate in regular jogging to improve and maintain a normal forced expiratory volume in one-second function.
