Aim.Establishing the effects of low intensity cycling (LC), moderate intensity cycling (MC), and standing at a simulated office workstation on pain modulation, work performance, and metabolic expenditure.Methods.36 healthy adults (21 females), mean age 26.8 (SD 7.6) years, partook in this randomized3×3crossover trial with 75 minutes of LC on 20% of maximum aerobic power (MAP) output, 30 minutes of MC on 50% of MAP, and standing 30 minutes with 48-hour wash-out periods. Outcome measures were pain modulation (pressure pain threshold (PPT) and thermal pain threshold)), work performance (transcription, mouse pointing, and cognitive performance), and metabolic expenditure.Results.PPTs increased in all conditions. PPT trapezius showed the highest increase after LC, 39.3 kilopascals (kPa) (15.6; 78.6), compared to MC, 17.0 kPa (2.8; 49.9), and standing, 16.8 kPa (−5.6; 39.4),p=0.015. Transcription was reduced during LC and MC. Mouse pointing precision was best during standing and worst and slowest during MC. Cognitive performance did not differ between conditions. Metabolic expenditure rates were 1.4 (1.3; 1.7), 3.3 (2.3; 3.7), and 7.5 (5.8; 8.7) kcal/minute during standing, LC, and MC, respectively(p<0.001).Conclusions.LC seems to be the preferred option; it raised PPTs, more than doubled metabolic expenditure, whilst minimally influencing work performance.

Treadmill Protocol

Accelerometers are designed to measure physical activity (PA) objectively. The MyWellness Key (MWK) accelerometer has been validated primarily in younger, normal-weight populations. The aims of this study were to examine the accuracy of the MWK against directly measured lab-based exercise and free-living PA in people with type 2 diabetes, many of whom are older and overweight or obese. Thirty-five participants with type 2 diabetes completed the protocol, which included a laboratory-based session and a free-living phase. In the laboratory visit, participants completed a structured treadmill protocol wearing MWKs on each hip (all subjects) and bra cup (women only). The speed where each MWK switched from recording light- to moderate-intensity activity was determined for each MWK worn. In the free-living phase, participants wore the MWK for all waking hours for 2 weeks, and recorded exercise in PA diaries immediately after each exercise session. The mean cut-points between low (“Free”) and moderate (“Play”) intensity for the right and left waist-worn MWKs were 4.1 ± 0.5 km/h and 5.0 ± 0.9 km/h for the bra-mounted MWK; ideal cut-point would be 4.0 km/h. In the free-living phase, the Spearman correlation between PA according to PA diary and the waist-worn MWK was 0.81 (95% confidence interval (CI): 0.76, 0.85; P < 0.001), but only 0.66 (95% CI: 0.53, 0.77; P < 0.001) when on the bra. In conclusion, the waist-worn MWK measured PA volume accurately, and was acceptably accurate at discriminating between low- and moderate-intensity PA in people with type 2 diabetes. The MWK underestimated PA volume and intensity when worn on a bra.

Background:It is currently not known how much walking should be advocated for good health in adolescent girls. The aim of this study was therefore to recommend health referenced standards for step defined physical activity relating to appropriate health criterion/indicators in a group of adolescent girls.Method:Two hundred and thirty adolescent girls aged between 12 to 15 years volunteered to take part in the study. Each participant undertook measurements (BMI, waist circumference, % body fat, and blood pressure) to define health status. Activity data were collected by pedometer and used to assess daily step counts and accumulated daily activity time over 7 consecutive days.Results:Individuals classified as ‘healthy’ did not take significantly more steps·day–1 nor spend more time in moderate intensity activity than individuals classified as at health risk or with poor health profiles.Conclusion:‘Healthy’ adolescent girls do not walk significantly more in term of steps·day–1 or time spent in activity than girls classified as ‘unhealthy.’ This could suggest that adolescent girls may not walk enough to stratify health and health related outcomes and as a result the data could not be used to inform an appropriate step guideline for this population.

The Impact

Recent reviews of the literature have demonstrated that exercise has a positive impact on cognitive performance. The purpose of this study was to assess the impact of an acute bout of aerobic exercise on executive functioning in college-age adults. For the experimental intervention, the effects of 20 min of self-paced moderate-intensity exercise on a treadmill were compared to the effects of a 20-min sedentary control period. Executive functioning was assessed using Stroop color-word interference and negative priming tests. Results indicated that the bout of exercise led to improved performance on the Stroop color-word interference task but no change in performance on the negative priming task. This finding suggests that exercise may facilitate cognitive performance by improving the maintenance of goal-oriented processing in the brain.

Background: Physical activity in the elderly is recommended by international guidelines to protect against cognitive decline and functional impairment. Objective: This Randomized Controlled Trial (RCT) was set up to verify whether medium-intensity physical activity in elderly people living in the community is effective in improving cognitive performance. Design: RCT with parallel and balanced large groups. Setting: Academic university hospital and Olympic gyms. Subjects: People aged 65 years old and older of both genders living at home holding a medical certificate for suitability in non-competitive physical activity. Methods: Participants were randomized to a 12-week, 3 sessions per week moderate physical activity program or to a control condition focused on cultural and recreational activities in groups of the same size and timing as the active intervention group. The active phase integrated a mixture of aerobic and anaerobic exercises, including drills of “life movements”, strength and balance. The primary outcome was: any change in Addenbrooke's Cognitive Examination Revised (ACE-R) and its subscales. Results: At the end of the trial, 52 people completed the active intervention, and 53 people completed the control condition. People in the active intervention improved on the ACE-R (ANOVA: F(1;102)=4.32, p=0.040), and also showed better performances on the memory (F(1;102)=5.40 p=0.022) and visual-space skills subscales of the ACE-R (F(1;102)=4.09 p=0.046). Conclusion: A moderate-intensity exercise administered for a relatively short period of 12 weeks is capable of improving cognitive performance in a sample of elderly people who live independently in their homes.

AbstractParticipating in singing is considered to have a range of social and psychological benefits. However, the physiological demands of singing, whether it can be considered exercise, and its intensity as a physical activity are not well understood. We therefore compared cardiorespiratory parameters while completing components of Singing for Lung Health (SLH) sessions, with treadmill walking at differing speeds (2, 4, and 6km/hr). Eight healthy adults were included, none of whom reported regular participation in formal singing activities. Singing induced physiological responses that were consistent with moderate intensity activity (METS: median 4.12, IQR 2.72 - 4.78), with oxygen consumption, heart rate, and volume per breath above those seen walking at 4km/hr. Minute ventilation was higher during singing (median 22.42L/min, IQR 16.83 - 30.54) than at rest (11L/min, 9 - 13), lower than 6km/hr walking (30.35L/min, 26.94 - 41.11), but not statistically different from 2km/hr (18.77L/min, 16.89 - 21.35) or 4km/hr (23.27L/min, 20.09 - 26.37) walking. Our findings suggest the metabolic demands of singing may contribute to the health and wellbeing benefits attributed to participation. However, if physical training benefits result remains uncertain. Further research including different singing styles, singers, and physical performance impacts when used as a training modality is encouraged.

Non Communicable Diseases are the biggest cause of death worldwide. There are eight major risk factors, out of which four of them are behavioral risk factors (tobacco use, harmful alcohol consumption, unhealthy diets and physical inactivity) and four of them are biological risk factors. The general objective of this study is to assess prevalence of behavioral risk factors of non-communicable diseases among adolescents. The study was conducted on students of higher secondary schools of Lalitpur. A descriptive cross-sectional study was conducted with the sample size 396. Structured questionnaire developed by STEPS SURVEY Nepal 2013 was used for data collection. Data management, analysis and interpretation were done using SPSS 20 version by calculating frequency and percentage. The prevalence of current tobacco (smoking) consumption was 17.2% and the prevalence of smokeless tobacco consumption was 8.1%. Current alcohol consumption was 14.4%. The prevalence of inadequate vigorous intensity activity was 58.3% and moderate intensity activity was 50.5%. The prevalence of fruit and vegetables consumption was 21.2% and 60.4% respectively. On the basis of findings of study it is concluded that use of tobacco products and alcohol was higher in male than female. All of the students consumed fruits and vegetables at least once a day but none of adolescents follow the consumption of fruits and vegetables as recommended by WHO. The adolescents were active as they involved in both vigorous and moderate intensity activity. The private schools students were less involved in physical activity as compared to public schools.

Abstract Background The feasibility of wrist-worn accelerometers, and the patterns and determinants of physical activity, among people on dialysis are uncertain. Methods People on maintenance dialysis were fitted with a wrist-worn AxivityAX3 accelerometer. Subsets also wore a 14-day electrocardiograph patch (Zio®PatchXT) and wearable cameras. Age-, sex- and season-matched UK Biobank control groups were derived for comparison. Results Median (interquartile range) accelerometer wear time for the 101 recruits was 12.5 (10.4–13.5) days, of which 73 participants (mean age 66.5 years) had excellent wear on both dialysis and non-dialysis days. Mean (standard error) overall physical activity levels were 15.5 (0.7) milligravity units (mg), 14.8 (0.7) mg on dialysis days versus 16.2 (0.8) mg on non-dialysis days. This compared with 28.1 (0.5) mg for apparently healthy controls, 23.4 (0.4) mg for controls with prior cardiovascular disease (CVD) and/or diabetes mellitus and 22.9 (0.6) mg for heart failure controls. Each day, we estimated that those on dialysis spent an average of about 1 hour (h/day) walking, 0.6 h/day engaging in moderate-intensity activity, 0.7 h/day on light tasks, 13.2 h/day sedentary and 8.6 h/day asleep. Older age and self-reported leg weakness were associated with decreased levels of physical activity, but the presence of prior CVD, arrhythmias and listing for transplantation were not. Conclusions Wrist-worn accelerometers are an acceptable and reliable method to measure physical activity in people on dialysis and may also be used to estimate functional behaviours. Among people on dialysis, who are broadly half as active as general population controls, age and leg weakness appear to be more important determinants of low activity levels than CVD.

This study examined the utility of motivation as advanced by self-determination theory (Deci & Ryan, 2000) in predicting objectively assessed bouts of moderate-intensity exercise behavior. Participants provided data pertaining to their exercise motivation. One week later, participants wore a combined accelerometer and heart rate monitor (Actiheart; Cambridge Neurotechnology Ltd) and 24-hr energy expenditure was estimated for 7 days. After controlling for gender and a combined marker of BMI and waist circumference, results showed autonomous motivation to positively predict moderate-intensity exercise bouts of ≥10 min, ≥20 min, and an accumulation needed to meet public health recommendations for moderate-intensity activity (i.e., ACSM/AHA guidelines). The present findings add bouts of objectively assessed exercise behavior to the growing body of literature that documents the adaptive consequences of engaging in exercise for autonomous reasons. Implications for practice and future work are discussed.
