The subjects underwent assessments of energy intake (by a 3-day weighted dietary record), body weight (by a digital scale), body composition (by whole-body dual-energy X-ray absorptiometry), VO2max (by a cycling ergometer), muscle strength (by a Biodex System 3 dynamometer) and blood analysis.Results: There were no significant interactions (P = 0.100&sim; 0.730) among energy intake variables. RE led to decreased fat mass (− 4.39%, P < 0.05) and improved cardiorespiratory capacity (+11.66%, P < 0.05), as well as increases in lean mass (+2.12%, P < 0.01) and muscle strength variables (+8.41&sim;+11.00%, P < 0.01 for all), without significant weight change. Although AE induced decreases in fat mass (− 5.91%, P < 0.05) and weight (− 2.28%, P < 0.05) and improved cardiorespiratory capacity (+19.07%, P < 0.01), lean mass and muscle strength variables remained unchanged. RE showed a stronger positive influence than AE on lean mass (P = 0.003) and muscle strength variables (P = 0.001&sim; 0.015), and RE and AE had similar influences on weight, fat mass, cardiorespiratory capacity and blood markers.Conclusion: It may be an efficient exercise regimen to perform RE first and then utilize AE to maintain the changes that occur in response to RE.Keywords: aerobic exercise, body composition, blood marker, cardiorespiratory capacity, obesity, muscle strength, resistance exercise, weightKim BKim SDove Medical Pressarticleaerobic exercisebody compositionblood markercardiorespiratory capacityobesitymuscle strengthresistance exerciseweightSpecialties of internal medicineRC581-951ENDiabetes, Metabolic Syndrome and Obesity: Targets and Therapy, Vol Volume 13, Pp 267-276 (2020)
