  Figure 1. Lipid and glucose metabolism are risk factors for cardiovascular disease; (a) Change of TC; (b) change of HDLC; (c) change of LDLC; (d) change of TG; and (e) change of glucose in LFT and HFT groups according to 12 weeks intervention. p < 0.05; a, Baseline vs. 12 wks; b, time × group; wks, weeks; LFT, low-frequency training; HFT, high-frequency training; ES, effect size; T × G, time × group. TC, total cholesterol; HDLC, high-density lipoprotein cholesterol; LDLC, low-density lipoprotein cholesterol; TG, triglycerides. Blue boxplots are baselines corresponding to pre-intervention, and red boxplots are 12-wks post-interventions.

  Figure 2. Change in physical fitness; (a) Change of relative VO2 peak; (b) change of absolute VO2 peak; (c) change of anaerobic threshold; (d) change of exercise duration; (e) change of grip strength; and (f) change of knee extension strength in LFT and HFT groups according to 12 weeks intervention. p < 0.05; a, Baseline vs. 12 wks; wks, weeks; LFT, low-frequency training; HFT, high-frequency training; ES, effect size. Blue boxplots are baselines corresponding to pre-intervention, and red boxplots are 12-wks post-interventions.

  Figure 3. Change in quality of life; (a) Change of physical section; (b) change of mental section; (c) change of total score anaerobic in LFT and HFT groups according to 12 weeks intervention. p < 0.05; a, Baseline vs. 12 wks; LFT, low-frequency training; HFT, high-frequency training; ES, effect size. Blue boxplots are baselines corresponding to pre-intervention, and red boxplots are 12-wks post-interventions.
