To investigate the effect of cyclic resistance training based on traditional Chinese medicine(TCM) breathing guidance theory on various physiological parameters in young women,including maximal oxygen uptake(VO2max),ventilatory threshold(VT),heart rate(HR),and+Gz endurance after 8-week training and explore the relationship between aerobic capacity and+Gz endurance.Methods:Twenty-four young women aged 20 to 32,without prior systematic training experience,were randomly assigned to a control group and an observation group.The observation group underwent 8 weeks of moderate-intensity cyclic resistance training,three times per week for 60 min each session.Before and after the training period,both groups underwent tests to evaluate exercise cardiopulmonary function and+Gz endurance.Results:Compared to their own pre-training values and to the control group post-training,the observation group showed significant increases in VO2max(P<0.05),VT(P<0.01),and+Gz tolerance endurance time(P<0.05).The number of participants who completed+3.5 Gz was higher when VO2max was in the range of 36 to 42 mL/(min·kg).When VO2max was less than or equal to 42 mL/(min·kg),there was a significant positive correlation between+Gz tolerance endurance time and both VO2max and VT(P<0.01).Conclusion:The findings suggest that 8 weeks of cyclic resistance training based on TCM breathing guidance theory effectively enhances aerobic capacity and+Gz endurance in young women.Women with VO2max in the range of 36 to 42 mL/(min·kg) show higher+Gz tolerance endurance.VT and HR can be scientifically used as a non-invasive means of controlling exercise intensity in aerobic endurance training to enhance+Gz tolerance.
