“…Finally, a study in adolescent girls demonstrated that RPE was significantly lower during a self-selected exercise session compared to a prescribed session of matched intensity (72% VO 2peak ) (25). These are just three examples of many possible strategies (39) to examine in the future to determine whether increasing enjoyment or decreasing perceived exertion of exercise is effective in reducing the likelihood of a compensatory response in post-exercise food intake.…”

PURPOSE To examine the individual-level factors that predict energy intake (EI) following imposed exercise (EX) and sedentary time (SED) in children. METHODS Healthy-weight children ages 9-12 years (n = 20) reported to the laboratory for 1 baseline and 2 experimental visits (EX and SED) each separated by 1 week in a randomized crossover design. Percent body fat, weight (kg), and height (m) were used to calculate fat-mass index (FM index) and fat-free mass index (FFM index; kg/m2). On the EX day, children exercised at 70% estimated VO2peak for 30 minutes on a cycle ergometer while cardiovascular responses and ratings of perceived exertion (RPE) were measured. Objective EI (kcal) was measured at identical meals (breakfast, lunch, snack, and dinner) on the EX and SED days. RESULTS Total EI was not statistically different between the EX and SED days (t = 1.8, p = 0.09). FFM index was positively associated with EI on the EX day (r = 0.54, p < 0.05). RPE was also positively associated with EI on the EX day (r = 0.82, p < 0.001). Together, FFM index and RPE explained 77% of the variability in EX day EI (F(2,17) = 26.4, p < 0.001). For each unit increase in RPE, children consumed ~270 more calories on the EX day. A similar pattern of associations was observed on the SED day. CONCLUSION FFM index was positively associated with EI on the EX day. Despite experiencing the same 70% relative exercise intensity, increased perceived difficulty predicted greater EI on both the EX and SED day. These findings demonstrate a role for both FFM and RPE in explaining EI variability in children.

“…In this context, leg cycling in the range of low power output is a non‐weight‐bearing movement that can easily be performed by most people (trained or untrained) and well tolerated (Thivel et al. ). It is easier to standardize than other modes of physical activity and provides an accurate measurement of the external work performed.…”

Standardized approaches to assess human energy expenditure (EE) are well defined at rest and at moderate to high‐intensity exercise, but not at light intensity physical activities energetically comparable with those of daily life (i.e., 1.5–4 times the resting EE, i.e., 1.5–4 METs). Our aim was to validate a graded exercise test for assessing the energy cost of low‐intensity dynamic work in physically inactive humans, that is, those who habitually do not meet the guidelines for moderate‐to‐vigorous aerobic physical activity levels. In healthy and inactive young men and women (n = 55; aged 18–32 years), EE was assessed in the overnight‐fasted state by indirect calorimetry at rest and during graded cycling between 5 and 50W for 5 min at each power output on a bicycle ergometer. Repeatability was investigated on three separate days, and the effect of cadence was investigated in the range of 40–90 rpm. Within the low power range of cycling, all subjects perceived the exercise test as “light” on the Borg scale, the preferred cadence being 60 rpm. A strong linearity of the EE‐power relationship was observed between 10 and 50 W for each individual (r > 0.98), and the calculation of delta efficiency (DE) from the regression slope indicated that DE was similar in men and women (~29%). DE showed modest inter‐individual variability with a coefficient of variation (CV) of 11%, and a low intra‐individual variability with a CV of ~ 5%. No habituation or learning effect was observed in DE across days. In conclusion, the assessment of the efficiency of low power cycling by linear regression – and conducted within the range of EE observed for low‐intensity movements of everyday life (1.5–4 METs) – extends the capacity for metabolic phenotyping in the inactive population.

Objective:The aim of this study was to determine the effects of active video games and music-accompanied aerobic and callisthenic exercises on body mass index (BMI), body fat ratio, physical performance tests, psychosocial status, and self-respect in overweight and obese adolescents.Methods:Fifty (21 males and 29 females) slightly overweight and obese participants with no chronic disorder and of an average age of 12.16±0.99 years were included in the study. The percentile values for BMI, triceps skinfold thickness, waist circumference measurements, and physical performance tests were evaluated. The effects of obesity on psychological wellness were evaluated using the depression scale for children (DSC) and the Piers-Harris Children’s Self-Concept Scale for self-esteem. Following these evaluations, the participants were subjected to an exercise program in five groups of 10 people, 3 days a week for a duration of 8 weeks. Each exercise session lasted 45 minutes. Participants were re-evaluated at the end of the exercise program. The data collected both before and after the exercise program were analyzed using the SPSS 18.0 program.Results:According to BMI reference values, 28% of the 50 participants (n=14; 6 males and 8 females) were assessed to be overweight and 72% to be obese (n=36; 15 males and 21 females). Following the exercise program, 14% of the participants (n=7; 3 males and 4 females) were assessed as normal, 46% (n=23; 14 males and 9 female) as slightly overweight, and 40% (n=20; 4 male and 16 female) as obese. It was determined that the decrease in BMI values (p<0.05) was higher in male participants than in female participants and that the frequency of obesity was higher in the females. A statistically significant decrease in BMI values was found after the exercise program (p<0.01). Following the exercise program, statistically significant differences have also been observed in the self-esteem (p<0.01), psychological wellness (p=0.025), triceps skinfold thickness, as well as in waist circumference and BMI values of the participants compared to the pre-exercise phase (p<0.01).Conclusion:An exercise program applied with active video games was found to have positive effects on the obese state as well as on the psychosocial status and self-esteem of obese individuals, indicating that exercise and physical activity have an important role in improvement of the obese state in childhood as well as having positive contributions to self-esteem and psychological wellness state.
