“…Although important for overall health [12–15], exercise generally falls short on the goal of weight loss (effect size is typically less than 3% of body weight, even in studies lasting more than a year) [1–4]. This is surprising, as physical activity is associated with acute increases in energy expenditure [16, 17]. One explanation for the limited effect of exercise on weight is that exercise increases hunger, and the calories burned through exercise are thus recovered by increased food intake [18].…”

Increases in Physical Activity Result in Diminishing Increments in Daily Energy Expenditure in Mice

SUMMARY Exercise is a common component of weight loss strategies, yet exercise programs are associated with surprisingly small changes in body weight [1–4]. This may be due in part to compensatory adaptations, in which calories expended during exercise are counteracted by decreases in other aspects of energy expenditure [1, 5–10]. Here, we examined the relationship between a rodent model of voluntary exercise – wheel running – and total daily energy expenditure. Use of a running wheel for 3 to 7 days increased daily energy expenditure, resulting in a caloric deficit of approximately 1 kcal/day; however, total daily energy expenditure remained stable after the first week of wheel access, despite further increases in wheel use. We hypothesized that compensatory mechanisms accounted for the lack of increase in daily energy expenditure after the first week. Supporting this idea, we observed a decrease in off-wheel ambulation when mice were using the wheels, indicating behavioral compensation. Finally, we asked whether individual variation in wheel use within a group of mice would be associated with different levels of energy expenditure. Despite large variation in wheel running, we did not observe a significant relationship between the amount of daily wheel running and total daily energy expenditure or energy intake across mice. Together, our experiments support a model in which the transition from sedentary to light activity is associated with an increase in daily energy expenditure, but further increases in physical activity produce diminishingly small increments in daily energy expenditure.

“…32, 46 Prior studies have advocated for strategies such as walking or calisthenics exercises. 47, 48 In particular, calisthenics exercises were associated with greater energy expenditure and heart rate response when compared to other light-intensity physical activities. 47 Also, moving during television commercials and while talking on the telephone can be easily incorporated into one’s lifestyle.…”

Background Limited data exist on the benefits of, barriers to, and potential strategies to break up time spent sitting in cancer survivors. Such data will be meaningful given the consequences of prolonged sitting. Objectives To conduct a mixed method research study consisting of semi-structured telephone interviews to identify recurrent themes associated with prolonged sitting in cancer survivors. Methods African American breast cancer survivors (N = 31) were recruited from a local tumor registry. Telephone interviews were conducted and group consensus processes were used to identify recurrent themes. The a priori categories were benefits, barriers, and potential strategies to breaking up prolonged periods of sitting. Results Recurrent themes contributing most to prolonged sitting were leisure time interest (45%: e.g., watching television and reading) and health challenges (27%: e.g., pain and fatigue). Most (66%) women perceived improved health as benefits to breaking up time spent sitting. Nonetheless, many (41%) survivors reported health (e.g., pain and fatigue) as the biggest challenge to breaking up time spent sitting. Engaging in light intensity activities (e.g., staying active, keep moving) was the most commonly reported strategy for breaking up prolonged sitting. Conclusions African American breast cancer survivors identified the benefits and barriers to breaking up time spent sitting as well as potential strategies to breaking up time-spent sitting. Implications for practice Clinicians are integral in promoting breaks from prolonged sitting throughout the initial phases of the cancer continuum. Successful studies will begin with early intervention in the clinical setting, following with interventions during the recovery phase.

“…Feasible strategies to reduced prolonged sitting might be focused on environmental restructuring and self-regulatory techniques such as self-monitoring [53], problem solving, or providing information on health consequences [54]. In addition, interventions focused on increasing low-energy expenditure activities (such as standing) [55] or including calisthenics as a break during prolonged sitting [56] might lead to more favourable patterns of ST. Indeed, activities of light intensity might be more feasible in these patients who often encounter difficulties in performing recommended amounts of MVPA [21,24].…”

To examine the associations of prolonged sedentary time (ST) with disease severity in women with fibromyalgia, and to analyse the combined association of total ST and prolonged ST with the disease severity in this population. Women (n = 451; 51.3 ± 7.6 years old) with fibromyalgia participated. Sedentary time and moderate-to-vigorous physical activity (MVPA) were measured using triaxial accelerometry and ST was processed into 30-and 60-min bouts. Dimensions of fibromyalgia (function, overall, symptoms) and the overall disease impact were assessed with the Revised Fibromyalgia Impact Questionnaire (FIQR). Body fat percentage was assessed using a bio-impedance analyser, and physical fitness was assessed with the Senior Fitness Tests Battery. Greater percentage of ST in 30-min bouts and 60-min bouts were associated with worse function, overall, symptoms and the overall impact of the disease (all, P < 0.05). Overall, these associations were statistically significant when additionally controlling for MVPA and overall physical fitness. Participants with low levels of total ST and prolonged ST (>60-min bouts) presented lower overall impact compared to participants with high levels of total ST and prolonged ST (mean difference = 6.56; 95% confidence interval (CI) = 1.83 to 11.29, P = 0.002). Greater percentage of ST accumulated in 30and 60-min bouts and a combination of high levels of total and prolonged ST are related to worse disease severity. Although unable to conclude on causality, results suggest it might be advisable to motivate women with fibromyalgia to break prolonged ST and reduce their total daily ST.
