Background:Compared with structured/organized activities, unstructured, self-selected physical activity (PA) may be more appealing for children in particular obese (OB) children. We examined whether both healthy-weight (HW) and OB children would engage in moderate to vigorous intensity PA during an unstructured PA program and compared heart rate (HR) and rate of perceived exertion (RPE) between the children.Methods:Twenty-one children [9 OB (≥95th BMI percentile, 12 HW (5th – <85th), 8.6 ± 0.8 years; 9 males, 12 females] participated in before-school (7:30 AM to 8:15 AM) PA for 18 weeks, 3 consecutive days/week. Each child wore a Polar E600 HR monitor and was provided a vigorous, age-targeted heart rate (THR) of 70%.Results:Mean HR ≥ vigorous THR for all children in 65.3% of the sessions and exceeded moderate intensity in 100%. Over the 18-weeks, no significant difference was observed in the overall mean HR between the HW (171.4 ± 12.0) and OB (169.3 ± 13.0), however the OB reported significantly lower RPEs than the HW (16.9 ± 2.6 vs. 17.6 ± 1.5, respectively; P < .05).Conclusions:Both the HW and OB children consistently sustained PA of moderate and vigorous intensity. The current study provides insight regarding the physiological capabilities and perceptual responses of HW and OB children participating in PA programs.

Background: Glucose concentrations in a fasted and during a glucose challenged state rely on different mechanisms for regulation. In a fasted state, hepatic regulation of glucose is important; while in a glucose challenged state, muscle glucose disposal becomes more important. Evidence suggests that physical activity of moderate or higher intensities can increase muscle glucose disposal during an insulin-stimulated state, but has less effect on hepatic insulin sensitivity. The purpose of this study was to examine the associations between glucose concentrations (fasting and after an oral glucose ingestion) and minutes of physical activity at moderate- and vigorous-intensity in a large population. Methods: The sample included 2,807 adults (47.4% male and 52.6% female) aged 18-80 years who participated in the National Health and Nutritional Examination Surveys (NHANES) from 2013-2014 and who did not take any diabetic medications. Minutes being physically active at moderate- and vigorous-intensities during work, and recreationally, were collected using the Physical Activity Questionnaire, which was based on the Global Physical Activity Questionnaire. Moderate-intensity physical activity was defined as any activity that caused a small increase in breathing or heart rate, while vigorous-intensity physical activity was defined as large increases in breathing or heart rate. Both intensities had to be performed for a minimum of 10 continuous minutes. Plasma glucose concentrations at fasting and 2 hours after consumption of a drink containing 75g glucose (2-hour glucose) were determined. Pearson product correlations were performed for analysis. Results: The population had 141±133 (mean±SD) minutes of moderate-intensity physical activity during work and 63±56 minutes recreationally, as well as 174±156 minutes of vigorous-intensity physical activity during work and 77±56 minutes recreationally. Minutes of vigorous-intensity physical activity performed during work was associated with 2-hour plasma glucose concentrations (r=0.15; p=0.045); this association was not affected after adjusting for age, race, and sex (p=0.049), but was no longer significant after BMI was also adjusted (p=0.059). Recreational or total minutes of vigorous-intensity physical activity, and moderate-intensity physical activity was not associated with 2-hour glucose (p>0.20). Additionally, none of the physical activity minutes was associated with fasting glucose (p>0.27). Conclusion: Self-reported vigorous-intensity physical activity during work was positively associated with 2-hour glucose, but not fasting glucose. The results are surprising. Further studies with objective physical activity measures are needed to examine the associations with fasting and 2-hour glucose.

Background:Maternal physical activity declines across gestation, possibly due to changing perception of physical activity intensity. Our purpose was to a) determine whether rating of perceived exertion (RPE) during a treadmill exercise changes at a given energy expenditure, and b) identify the influence of prepregnancy physical activity behavior on this relationship.Methods:Fifty-one subjects were classified as either exercisers (N = 26) or sedentary (N = 25). Participants visited our laboratory at 20 and 32 weeks gestation and at 12 weeks postpartum. At each visit, women performed 5 minutes of moderate and vigorous treadmill exercise; speed was self-selected. Heart rate (HR), oxygen consumption (VO2), and RPE were measured during the last minute at each treadmill intensity.Results:At moderate intensity, postpartum VO2 was higher compared with 20- or 32-week VO2, but there was no difference for HR or RPE. For vigorous intensity, postpartum HR and VO2 were higher than at 32 weeks, but RPE was not different at any time points.Conclusions:RPE does not differ by pregnancy time point at either moderate or vigorous intensity. However, relative to energy cost, physical activity was perceived to be more difficult at 32 weeks compared with other time points. Pregnant women, then, may compensate for physiological changes during gestation by decreasing walking/running speeds.

Background:This study validated the short- and long-form New Zealand Physical Activity Questionnaires (NZPAQ-SF and NZPAQ-LF) against heart-rate monitoring (HRM) with individual calibration.Methods:A multiethnic sample (N = 180), age 19 to 86 y, underwent HRM for 3 consecutive days while simultaneously completing physical activity (PA) logs.Results:Both NZPAQs showed significant (p < .001) correlations to HRM data for brisk walking (r = .27–.43), vigorous-intensity PA (r = .27–.35), and total PA (r = .25; 95% CI, 0.10-0.40), whereas moderate-intensity PA was substantially overreported (mean = 157-199 min). Although the NZPAQ-LF performed better for brisk walking and vigorous-intensity PA, the NZPAQs were strongly correlated (r = .61 and r = .52, respectively, p < .0001). European/Other participants demonstrated the most accurate PA recall of total PA on both NZPAQs (r = .36−.41, p < .01).Conclusions:The NZPAQs are acceptable instruments for measuring adult PA levels and produce similar results. Substituting culturally specific examples of PAs on the NZPAQs and their accompanying show cards could potentially improve PA recall for Maori and Pacific people.

The temporary closure of learning institutions during the COVID-19 pandemic has dramatically reduced the physical activity of students across all ages. Therefore, this study aimed to investigate the prevalence of physical inactivity and the patterns of physical activity among university students in confinement. This cross-sectional study involved 147 Malaysian students and 107 Indonesian students. Body weight before the pandemic and during the pandemic was self-reported by the respondents, and the International Physical Activity Questionnaire-Short Form (IPAQ-SF) was used to assess the physical activity and sedentary behavior of the respondents. The findings revealed that 79.6% of Malaysians and 77.6% of Indonesians were physically active during the confinement. There was no significant difference (p < 0.05) in the duration devoted to vigorous-intensity activity (MMalaysian = 0.00 MET minutes/week and MIndonesian = 480.00 MET minutes/week) and moderate-intensity activity (MMalaysian = 0.00 MET minutes/week and MIndonesian = 0.00 MET minutes/week) among the studied population. During the pandemic, Malaysian students (M = 1386.00 MET minutes/week) devoted a significantly higher duration to walking (M = 1386.00 MET minutes/week) and sedentary behavior (9.16 ± 4.47 h/day) than Indonesian students (M = 990.00 MET minutes/week and sedentary behavior = 7.85 ± 4.27 h/day). Overall, no significant difference was noted in the total physical activity of Malaysian and Indonesian students during the pandemic (MMalaysian = 2826.00 MET minutes/week and MIndonesian = 1782.00 MET minutes/week). Findings from Spearman’s rank correlation test suggested that there was a weak inverse correlation between the duration engaged in vigorous-intensity activity and weight change among the Malaysian students (rs = −0.199, p = 0.016), after adjusting for gender and age. Overall, the closure of learning institutions and exercise facilities has further prevented individuals from complying with the WHO recommendation of moderate-to-vigorous physical activity during the period of home confinement.

The purpose of the study was to assess the intensity of aerobic physical activity during exergame training sessions with a moderate (MLD) and high (HLD) level of difficulty of the interactive program “Your Shape Fitness Evolved 2012” for Xbox 360 Kinect in the context of health benefits. The study involved 30 healthy and physically fit students. During the game, the HR of the participants was monitored using the Polar M400 heart rate monitor. The average percentage of maximum heart rate (%HRmax) and heart rate reserve (%HRR) during the game was calculated and referred to the criterion of intensity of aerobic physical activity of American College of Sports Medicine and World Health Organization health recommendations. During the MLD training, the participants achieved on average 69.6 ± 8.7%  HRmax and 57.0 ± 11.9% HRR (moderate intensity), while performing HLD exercises, they achieved 78.9 ± 8.1%  HRmax and 70.2 ± 11.3% HRR (vigorous intensity). The time spent in recommended moderate-to-vigorous intensity during 15-min exergame session was 14.6 min (97,1%) for MLD and 14.8 min (99%) for HLD. The intensity of aerobic PA during exergame “Your Shape Fitness Evolved 2012” both medium and high level of difficulty almost all the training sessions was at the level recommended for health benefits. Active video games, especially exergames, containing an element of physical activity, can be used to increase the weekly dose of PA in the direction recommended for health benefits.

Background: The Physical Activity Scale (PAS2) was developed to measure physical activity (PA) during work, transportation and leisure time, in the Danish adult population. The objective of this study was to assess the criterion validity of PAS2 against a combined accelerometer and heart rate monitor in Danish adults and to investigate if the criterion validity differed by socio-demographic factors and body mass index. Method: A total of 330 Danish adults (mean age = 46.7 years, 38.5% men) participating in the Health2008 study completed the PAS2 questionnaire and wore a combined accelerometer and heart rate sensor for seven days. Average daily estimates from PAS2 were categorised into time spent in sedentary behaviour, light PA, moderate PA and vigorous PA and were compared to the objective measures. Results: PAS2 accounted for 19.5 hours/day on average. Time spent in sedentary behaviour, light and moderate-intensity PA was weakly correlated with objective data (polychoric correlation coefficients (PCC): 0.18–0.20), whereas vigorous intensity PA was moderately correlated (PCC: 0.54, p = 0.04). Mean bias was −2.3 hours/day (95% limits of agreement (LoA): −9.04 to 4.34) for sedentary behaviour, 1.68 hours/day (LoA: 8.02 to −4.62) for light activity, 0.55 hours/day (LoA: 3.37 to −2.26) for moderate activity and 0.12 hours/day (LoA: 0.57 to 0.33) for vigorous activity. Criterion validity was lower in women, in participants who were above 40 years, overweight, had short education and were unemployed. Conclusions: PAS2 overestimated time spent on light, moderate and vigorous intensity PA and underestimated time spent on sedentary behaviour. Validity differed by key socio-demographic characteristics.

Identifying alternative exercise modalities in an effort to stimulate and promote participation in physical activity, especially among older adults, is a critical health consideration. The purpose of this study was to compare physiological and psychological responses to medical qigong with self-paced brisk walking. Older women (55–79 years) performed 22 min of either qigong or walking on two separate days. During exercise performance, heart rate and ratings of perceived exertion were assessed. Psychological affect, blood pressure, and pulse rate were assessed before and after the exercise bouts. Heart-rate data indicated that both forms of exercise were at a moderate level of intensity. In addition, similar values were found for the physiological and psychological variables as a function of the two forms of exercise. Therefore, it was concluded that this form of medical qigong can be considered a moderate-intensity physical activity that should have both physiological and psychological benefits for older women.

This study validated the International Physical Activity Questionnaire (IPAQ) and the Context-specific Sedentary Behavior Questionnaire (CSBQ) against accelerometry among parents-to-be. Sex-differences in potential misreporting of physical activity (PA) and sedentary behavior (SB) were also investigated. Self-reported total PA (TPA), light-intensity PA (LPA), moderate-intensity PA (MPA), vigorous-intensity PA (VPA), moderate-to-vigorous-intensity PA (MVPA), and SB of 91 parents-to-be (41 men and 50 women) were compared with Actigraph data according to sex. Furthermore, the extent of misreporting was compared between sexes. Strong correlations for TPA and weak-to-moderate correlations for LPA, MPA, VPA, MVPA, and SB were observed. Participants underestimated TPA by 1068 min/week (=17.8 h/week; −50%), LPA by 1593 min/week (=26.6 h/week; −83%), and SB by 428 min/week (=7.1 h/week; −11%) and overestimated MPA by 384 min/week (=6.4 h/week; +176%) and MVPA by 525 min/week (=8.8 h/week; +224%). Males overreported VPA more than females in absolute minutes per week (238 min/week, i.e., 4.0 h/week vs. 62 min/week, i.e., 1.0 h/week), whereas, in relative terms, the opposite (+850% vs. +1033%) was true. The IPAQ and CSBQ can be used with caution to estimate TPA and SB among parents-to-be considering a strong correlation but low agreement for TPA and a weak-to-moderate correlation but acceptable agreement for SB. We disadvise using these self-reports to estimate PA on the distinct intensity levels.

The objective of the present cross-sectional study was to examine the associations of physical activity and the adherence to the Mediterranean dietary pattern (MDP) with bone mineral content (BMC) and density (BMD) in children with overweight and obesity. A total of 177 (n = 80 girls) children with overweight and obesity aged 8 to 12 years old participated in the study. Both BMC and BMD were assessed by Dual-Energy X-ray absorptiometry. Dietary patterns were assessed by the KIDMED questionnaire and two 24-hour recalls. Physical activity was assessed by accelerometers for 7 consecutive days (24 hours/day). Low adherence to the MDP was observed in 82.4% of participants. Higher physical activity levels (of at least moderate intensity) and lower sedentary time were significantly associated with BMC and BMD in children with low adherence to the MDP (all p < 0.05). No associations were observed between physical activity and BMC and BMD in children with high adherence to the MDP. In conclusion, engaging in moderate to vigorous physical activity and reducing the time spent in sedentary behavior might be particularly beneficial for improving bone health in overweight or obese children with poor adherence to the Mediterranean dietary pattern.
