Key result
Aerobic exercise was associated with significantly lower heart rate (P=0.002) and systolic blood pressure (P=0.021) compared to resistance exercise and sedentary controls.
Why the study?
Does aerobic or resistance exercise improve cardio-metabolic profiles in young healthy nonobese subjects?

Does aerobic or resistance exercise improve cardio-metabolic profiles in young healthy nonobese subjects?
Aerobic exercise provides superior cardio-metabolic benefits compared to resistance exercise or a sedentary lifestyle in healthy nonobese individuals, though it may be associated with benign elevations in serum creatinine.
May favor aerobic exercise for hemodynamics in healthy youth; extends observational data but leaves open causality and practice change.
Background and Aim: Exercise is considered the best preventive measure for cardiovascular (CV) morbidity. But, it is of paramount importance to know the type of exercise that provides maximum benefits. This study was planned to compare various CV and biochemical parameters in subjects performing different types of exercise. Methods: The study was performed on young healthy nonobese volunteers divided into three groups: Sedentary controls, resistance exercise and aerobic exercise groups. In all the groups, CV parameters viz., heart rate (HR) and blood pressure (systolic and diastolic) were measured and the blood sample were analyzed for fasting blood glucose (FBG), lipid profile, serum creatinine, blood urea, uric acid and C‑reactive protein (CRP) using standard procedures. This was followed by comparison of these parameters among the three groups. Results: HR (P = 0.002), systolic blood pressure (P = 0.021) and rate pressure product (P = 0.003) were significantly low in aerobic group in comparison to the sedentary controls as well as in resistance group. FBG (P = 0.010), total cholesterol (P < 0.001), low density lipoprotein (P < 0.001), triglyceride (P = 0.012) and lipid risk factors (P < 0.001) were significantly lower in subjects performing aerobic exercises than in subjects performing resistance exercises and in sedentary controls. Serum high‑density lipoprotein (HDL) (P < 0.001) was significantly higher in resistance and aerobic groups than in the control group. Serum creatinine was found to be significantly higher in the aerobic group with no significant dif ference in CRP level among the three groups. Conclusion: Aerobic exercises might have extra benefits due to less myocardial oxygen consumption and load, and increasing HDL. However, as creatinine level gets altered due to aerobic exercise in the absence of any renal damage, this should be taken into consideration while assessing renal functions in these individuals.

Bhandari et al. (2014) conducted a cross-sectional in Healthy nonobese. Aerobic exercise vs. Resistance exercise and sedentary controls was evaluated on Cardiovascular and biochemical parameters. Aerobic exercise was associated with significantly lower heart rate (P=0.002) and systolic blood pressure (P=0.021) compared to resistance exercise and sedentary controls.
