| Objective: To investigate the combined effects of resistance training combined with early morning fasted aerobic exercise and resistance training followed by immediate aerobic exercise on the differences in body composition and changes in the two exercise modes of the average male college student.Methods: Thirty two male non-physical major students from Shenyang Normal University were included in this study as experimental subjects and randomly divided into experimental and control groups(hereafter referred to as EG and CG).Both groups underwent a 6-week exercise intervention with resistance training combined with early morning fasted aerobic exercise in the EG and resistance training combined with immediate aerobic exercise after resistance training in the CG.Body composition indexes such as body weight,body fat mass,body fat percentage and skeletal muscle content were measured before and after the intervention with the In Body 220 Bioimpedance Body Composition Analyzer,while the two groups were rated weekly on four dimensions,namely,sense of mental exhilaration,sense of physical and psychological well-being,sense of physical fatigue and training motivation,by the Exercise-Induced Feeling Inventory(EFI).Paired-samples T-tests were conducted using SPSS 26.0 for the body composition indexes before and after the intervention in the group,and independent-samples T-tests were conducted for the variable of body composition indexes in each group after the intervention and the weekly scores of the Exercise-Induced Feeling Inventory(EFI)during the intervention.Results:(1)There was no significant change in body weight and skeletal muscle content,a significant increase in fat free mass or lean body mass(hereafter referred to as lean body mass)(P<0.05),and a significant decrease in body fat mass and body fat percentage(P<0.01)in EG after the intervention.Body weight,skeletal muscle content and lean body mass were significantly reduced(P<0.01)and body fat mass was significantly reduced(P<0.05)in CG after the intervention,with no significant change in body fat percentage.(2)CG reduced more body weight(P<0.05),skeletal muscle content and lean body mass(P<0.01)than EG after the intervention,whereas EG reduced more body fat mass(P<0.05)and body fat percentage(P<0.01)than CG.(3)During the intervention,EG scores were significantly higher than CG on feelings of mental exhilaration(P<0.05)and significantly lower than CG on feelings of physical fatigue(P<0.05)from the fourth week onwards.EG scored significantly higher than CG on training motivation from the fifth week onwards(p<0.05).Conclusion:(1)Resistance training combined with aerobic exercise through6 weeks,4 times a week in both exercise modes significantly reduces body fat mass in the average male student in college.(2)The traditional model is more conducive to weight loss,but is accompanied by a loss of skeletal muscle mass and lean body mass.(3)The new exercise pattern of resistance training combined with early morning fasted aerobic exercise is more conducive to reducing body fat mass and lowering body fat percentage while increasing lean body mass than the traditional pattern,in addition to ensuring a certain trend of growth in skeletal muscle mass.(4)The new exercise pattern of resistance training combined with early morning fasted aerobic exercise helps practitioner to maintain a good feeling of exercise,ensuring a sense of mental invigoration and motivation while generating less physiological fatigue,which helps practitioner to persevere.(5)Pain during and after training caused by postural problems can seriously affect the quality of resistance training,reduce gains in skeletal muscle content,in the meantime prevent positive changes in body composition from occurring. |
