Physical exercise is helpful in treatment of mental disorders. Many researches have addressed what effects can exercise generate to psychological health, yet no researches have compared the efficacies of different types of exercises. Consequently, this study compared how different types of exercises, including aerobic, anaerobic and combined exercises independently affect psychological health. In this study, 184 participants were recruited to fill in a questionnaire via an online survey platform (www.qualtrics.com). Generally, participants were asked to report their exercise habit (Aerobic, anaerobic, combined and none) and their psychological health was assessed by DASS-21 and GHQ-12. The data is analyzed by SPSS 21 and ANOVA was used. Chi square analysis was also conducted to measure the relationship among characteristics of exercise including frequency, intensity and enjoyment of exercise. According to the results, no significant difference between groups was found in the scores in DASS-21. However, the three exercise groups revealed significantly better psychological health than the sedentary group in the GHQ-21 (p = .045). In addition, the relationship between intensity and enjoyment of exercise was approaching significance (p = .10). The current findings were not totally consistent to the existing literature. Limitation in the study design was discussed to explain the disparity between the recent study and the existing literature. Lastly, the main conclusion of this study was that exercise is generally beneficial in the psychological aspect; nonetheless the combined exercise may be a more time efficient and sustainable alternative.

His current work is on “It is time to exercise smart rather than exercise hard. A comparison of high intensity interval training and circuit training to traditional aerobic and anaerobic exercises”

The literature shows that physical exercise has numerous advantages on bodily health and psychological health including cardiovascular health improvement and alleviation of depression (Bartlett et al., 2011; Jayakody, Gunadasa, & Hosker, 2014; Winters-Stone et al., 2013). While exercise can be generally categorised as aerobic and anaerobic, high intensity interval training (HIIT) or high intensity circuit training (HICT) is introduced as a novel exercise technique which incorporates both aerobic and anaerobic function(Cheema & Gaul, 2006) . A wealth of scientific evidence supported that the benefits of HIIT and HICT on bodily health is even beyond traditional aerobic or anaerobic exercise alone (Gremeaux et al., 2011; Rognmo et al., 2004; Tjønna et al., 2008). Furthermore, a few clinical studies established that HIIT and HICT reduces psychological symptoms (Gerber et al., 2014;rnLaforgia, Withers, & Gore, 2006). Nevertheless, concurrently there is no research that compares therneffects of high intensity exercise to aerobic or anaerobic exercise on the psychological health domain. Thernpresent study makes an attempt to investigate whether HIIT and HICT is a more efficacious intervention for psychological health improvement in contrast to aerobic or anaerobic exercise.
