Abstract	The present study investigated the effects of circuit training, resistance training, and combined training on selected biochemical variables among school boys. A total of 60 school boys aged 15–17 years from R.S. Government Higher Secondary School, Paramakudi, Tamil Nadu, were selected and randomly assigned into four equal groups: circuit training group, resistance training group, combined training group, and control group, with 15 participants in each group. The experimental groups underwent their respective training programmes for 12 weeks, while the control group continued routine activities without any special training. The selected biochemical variables were low-density lipoprotein and high-density lipoprotein. Blood samples were collected before and after the training period, and the values were recorded in mg/dl. The data were analysed using analysis of covariance, and Scheffe’s post hoc test was applied wherever significant differences were observed. The results revealed significant differences among the groups in both low-density lipoprotein and high-density lipoprotein after the intervention. The combined training group showed the most favourable biochemical response by reducing low-density lipoprotein and increasing high-density lipoprotein levels more effectively than circuit training and resistance training alone. These findings indicate that a structured combination of circuit and resistance training may provide a stronger metabolic stimulus for improving lipid-profile markers among adolescent boys. Therefore, combined training can be recommended as an effective school-based training method for promoting better biochemical health and reducing cardiovascular risk factors among school boys.
