Effects Of NUTREND Sports Drink And Aerobic Resistance Training On Physical And Mental Health Of College Students

Objective: To explore the effect of NUTREND L-carnitine exercise supplement combined with aerobic resistance training on the physical and mental health of healthy college students through a randomized controlled trial.Methods: 60 healthy college students were randomly divided into two groups: aerobic resistance training combined with L-carnitine sports drink,and aerobic resistance training combined with placebo,30 in each group.Each group had eight weeks of exercise training,three times a week,and about 40 minutes each time.Take NUTREND drink(mainly L-carnitine)and placebo within 10～30 days before exercise.Physical and mental health related indicators were tested before and 8 weeks after the intervention.The main indicators were physical fitness indicators(maximum oxygen uptake,muscle strength,flexibility),mental health indicators(Symptom Checklist 90(SCL-90),Pittsburgh Sleep Quality Index(PSQI),and Chinese College Students’ Adaptation Scale(CCSAS)),Secondary indicators were body composition indicators(height,weight,BMI,body fat rate,lean weight,body moisture,waist hip ratio).Results: Among the physical fitness indexes,after 8 weeks of intervention,the maximum oxygen uptake,back muscle strength and grip strength of the experimental group and the control group were significantly improved compared with those before intervention(P<0.05).There was no significant change in flexibility indexes between the two groups.The results of inter group covariance showed that after 8 weeks of intervention,the maximum oxygen uptake(improvement value: 3.81 ± 3.32,P<0.05)and grip strength(improvement value: 1.76 ± 1.31,P<0.01)of the experimental group were better than those of the control group.In the mental health indicators,compared with those before intervention,after 8 weeks of intervention,the experimental group and the control group have significantly improved in terms of SCL-90 total score,obsessivecompulsive disorder,interpersonal sensitivity,paranoia,psychotic and other(sleep disorders and poor diet),PSQI total score,CCSAS total score,interpersonal applicability,school applicability,emotional applicability,and satisfaction(P < 0.01 or P < 0.05).In addition,the experimental group has significantly improved in terms of somatization,depression,and terror,There was significant improvement in learning applicability and self applicability(all P<0.05),and there was significant improvement in anxiety and job selection applicability in the control group(all P<0.05).Covariance results showed that after 8 weeks of intervention,the experimental group had better improvement in somatization(improvement value:-1.17 ± 1.14,P < 0.01),total PSQI score(improvement value:-2.14 ± 1.90,P < 0.05),learning applicability(improvement value: 3.14 ±4.51,P < 0.05)and emotional applicability(improvement value: 1.07 ± 3.70,P < 0.01).In the body composition indicators,compared with those before intervention,after 8 weeks of intervention,the experimental group and the control group had significant improvement in BMI,body fat rate,fat volume and waist hip ratio(P<0.05),but there was no statistical difference between the groups.Conclusion: Aerobic resistance training can promote the development of college students’ physical and mental health.However,the combination of L-carnitine and aerobic resistance training has a more significant effect on the physical and mental health of college students than the simple aerobic resistance training,mainly reflected in the maximum oxygen uptake,muscle strength,psychological condition,sleep status,and adaptation status.
