| Abstract | Purpose: Low-carbohydrate diets (LCs) seems to be effective on weight reduction and maintenance. However, the affect and enjoyment responses of exercise during LCs are not clear. The purpose of the present study was to compare the psychological responses to high-intensity interval training defined as sprint interval training (SIT) with moderate-intensity continuous training (MICT) on the consumption of a 4-week low carbohydrate diet (LC) diet in inactive young women. Methods: 68 sedentary young healthy women, aged 18-30 years, were recruited to participate in this study. They were randomly allocated them into a control group on a normal diet (CON), LC with moderate-intensity continuous exercise (MICT), and LC with high-intensity interval exercise (SIT) groups for a 4-week intervention study. The LC diet for both exercise groups was 10% carbohydrates, 70% fat, and 20% protein. The exercise regimen for the MICT group was 30 minutes of moderate-intensity cycling with 50-60% peak oxygen uptake (VO2peak), whereas the SIT group performed 10 sets of 6-second high-intensity interval cycling with 9-second passive rest each day. The exercise frequency was 5 times per week for the MICT and SIT. We collected Feeling Scale (FAS), Feeling Scale for Physical Activity (FS), Exercise Enjoyment Scale (EES), and Physical Activity Enjoyment Scale (PACES) before and after each exercise session throughout the study. We also measured anthropometric indicators and VO2peak before and after the intervention. Results: Compared to the CON group, both intervention groups lost about 4.0% of their body weight (p <0.01), and VO2peak improved by 10% (p <0.01). In the first week of the intervention, the EES of the SIT group was lower in the latter half of the week than the first half (p < 0.05), while the MICT group showed no significant changes. The acute psychological responses to exercise did not differ significantly between the two exercise groups (p >0.05). During the four-week intervention period, both exercise groups reported higher FAS and FS scores after exercise, but the SIT and MICT groups had similar FAS, FS, and EES responses. The PACES scores after exercise were more positive in the SIT group than the MICT group (p = 0.079, d = 0.56), but EES was similar. Conclusion: Short-term low-carbohydrate diets in conjunction with HIIT and MICT exercises can effectively reduce weight and improve cardiovascular fitness. Both exercise plans have similar emotional valence and arousal levels, as well as comparable exercise enjoyment responses among sedentary young women participants. Although SIT is more efficient in improving cardiovascular fitness under low-carbohydrate diets, MICT exercise is more enjoyable. |
