Abstract
AIMS: Restrictions during the COVID-19 crisis will have impacted on opportunities to be active. We aimed to (a) quantify the impact of COVID-19 restrictions on accelerometer-assessed physical activity and sleep in people with type 2 diabetes and (b) identify predictors of physical activity during COVID-19 restrictions. METHODS Participants were from the UK Chronotype of Patients with type 2 diabetes and Effect on Glycaemic Control (CODEC) observational study. Participants wore an accelerometer on their wrist for 8 days before and during COVID-19 restrictions. Accelerometer outcomes included the following: overall physical activity, moderate-to-vigorous physical activity (MVPA), time spent inactive, days/week with ≥30-minute continuous MVPA and sleep. Predictors of change in physical activity taken pre-COVID included the following: age, sex, ethnicity, body mass index (BMI), socio-economic status and medical history. RESULTS In all, 165 participants (age (mean±S.D = 64.2 ± 8.3 years, BMI=31.4 ± 5.4 kg/m2 , 45% women) were included. During restrictions, overall physical activity was lower by 1.7 mg (~800 steps/day) and inactive time 21.9 minutes/day higher, but time in MVPA and sleep did not statistically significantly change. In contrast, the percentage of people with ≥1 day/week with ≥30-minute continuous MVPA was higher (34% cf. 24%). Consistent predictors of lower physical activity and/or higher inactive time were higher BMI and/or being a woman. Being older and/or from ethnic minorities groups was associated with higher inactive time. CONCLUSIONS Overall physical activity, but not MVPA, was lower in adults with type 2 diabetes during COVID-19 restrictions. Women and individuals who were heavier, older, inactive and/or from ethnic minority groups were most at risk of lower physical activity during restrictions.

Abstract
OBJECTIVES Homocysteine (Hcy) has emerged as a risk factor for cardiovascular diseases (CVD). However the relationship of physical activity (PA) with Hcy levels in the elderly is controversial. Accordingly, the current study examined the effect of low and high participation in PA on serum Hcy in young (n = 77; 18-50 years) and old (n = 207; > 65 years) males (n = 141) and females (n = 142). METHODS Level of PA was obtained in a 1-to-1 interview and participants divided into low and high groups. Serum Hcy, folate, and vitamin B12 were obtained after 12 hour fast drawn by venipuncture. RESULTS Levels of Hcy correlated with folate (r = -0. 5; p = 0.000) and vitamin B12 (r = -0.3; p = 0.000). The ANOVA revealed a main effect of PA for Hcy (p = 0.04) but not for folate (p = 0.2) and vitamin B12 (p = 0.2). Main effects were found also of age for Hcy (p = 0.000) and folate (p = 0.005) as well as of gender for Hcy (p = 0.000) and vitamin B12 (p = 0.000). Subsequent ANCOVA showed lower levels of Hcy in the participants with greater versus lower PA even after controlling for B12 vitamin. CONCLUSION These results confirm the importance of the vitamins for regulating Hcy levels. Additionally, the data suggests that PA affects Hcy levels without affecting and independent of B vitamins in the elderly.

Abstract
The specific movement demands of soccer that are linked to post-match recovery and readiness to train are unclear. Therefore, we examined the relationship between Global Positioning System (GPS) variables and the change (Δ; from baseline) in Creatine Kinase (CK) concentrations and peak power output (PPO; during the countermovement jump) at 24h and 48h post-match. Fifteen English Premier League reserve team players were examined over 1-4 matches. Measurements of CK and PPO were taken before (24h prior to match-play) and after (+24h and +48h) each game during which movement demands were quantified using 10Hz GPS data. High intensity distance covered (r=0.386, p=0.029; r=-0.349; p=0.050), high intensity distance covered⋅min(-1) (r=0.365, p=0.040; r=-0.364, p=0.040), high speed running distance (r=0.363, p=0.041; r=-0.360, p=0.043) and the number of sprints⋅min(-1) (r=0.410, p=0.020; r=-0.368, p=0.038) were significantly related to ΔCK and ΔPPO at +24h post-match, respectively. No relationships were observed between any match variables and ΔCK and ΔPPO after +48h of recovery. These findings highlight that high intensity match activities are related to ΔCK and ΔPPO in the 24h, but not 48h, following soccer match-play. Such information is likely of interest to those responsible for the design of soccer player's training schedules in the days following a match.

PM & R : the journal of injury, function, and rehabilitation. 2016;(1):28-34
Abstract
BACKGROUND Ratings of perceived exertion (RPE) are used to monitor and prescribe exercise intensity for a variety of patient populations. It is important to understand RPE in different patient populations to ensure appropriate prescriptions and maximize the likelihood of adherence. Chronic liver diseases (CLDs) are a constellation of diseases that are associated frequently with fatigue, metabolic abnormalities, and cardiovascular disease, all targets for prescription of exercise. However, there have been no investigations of the correlates of RPE in those with CLD. OBJECTIVE To correlate RPE during a 6-minute walk test (6MWT) with biological/physiological measures in subjects with chronic hepatitis C (CH-C) and non-alcoholic fatty liver disease (NAFLD). DESIGN Observational analytical study. SETTING Specialty clinic. PARTICIPANTS A convenience sample of 51 subjects with NAFLD or CH-C (age: 51.1 ± 8.8 years, 35% female) was enrolled. Subjects receiving antiviral therapies or those with recent myocardial infarction, cardiovascular, or musculoskeletal comorbidities affecting exertion were excluded. METHODS Participants underwent fasting morning venipuncture, and resting cardiorespiratory data were collected. Then the participants completed a 6MWT. At the conclusion of the 6MWT, participants reported their RPE, and cardiorespiratory data were reassessed. MAIN OUTCOME MEASUREMENTS RPE, 6MWT, resting/postexertion cardiorespiratory data (eg, heart rate, cardiac output), Human Activity Profile (HAP), fasting morning glucose (GLU), total cholesterol (TC), lipids, and interleukin-8 (IL-8) were determined. RESULTS For the entire group, RPE was significantly correlated to serum IL-8 and GLU but not to the other factors. When we controlled for age and triglycerides, RPE remained significantly related to GLU (rs = 0.54; P = .04), maximal activity level (HAP) (rs = 0.58; P = .03), and distance walked (rs = 0.61; P = .03) in those with NAFLD. In those with CH-C, only IL-8 remained a strong correlate of RPE (rs = 0.54; P = .01). CONCLUSIONS In individuals with CH-C, RPE was related to an inflammatory factor, whereas in individuals with NAFLD, RPE was related to a metabolic and a lifestyle factor.

Abstract
BACKGROUND Physical activity (PA) is associated with health enhancement. The aim of this study was to assess: 1) levels and patterns of PA in university students by using accelerometers; and 2) the percentage of fulfilment of PA recommendations for adults, according to different public health guidelines. METHODS Observational cross-sectional study (Cuenca's Adults Study) involving 296 (206 women) healthy Spanish university students aged 18-25 years old. Participants wore the ActiGraph GT1M accelerometer for seven consecutive days. Total PA, steps and time spent in sedentary time, light, moderate, vigorous, and moderate to vigorous PA (MVPA) was assessed, and the prevalence of sufficient PA was calculated according to various public health guidelines. RESULTS No sex differences in total PA were found. University students were more sedentary during weekend days than weekdays (p<0.05). Only 30.3% of participants accumulated 30 min/day at least five days a week of MVPA. A total of 5.4% of students met the recommendation of 150 min/week of MVPA or 75 min/week of vigorous PA, in PA bouts of at least 10 min. using the same definition, but on five or more days a week, only 0.5% students were found to meet the recommendation. In addition, only 0.5% of students met the recommendation of 30 min/day of MVPA, at least five days a week and in bouts of at least 10 min. Finally, 28.1% of the students met the recommendation of 10,000 steps/day. CONCLUSIONS Our study shows a high incidence of sedentary time in university students. The number of students meeting PA recommendations significantly differed depending on the recommendation proposed. Specific strategies to promote PA in this population are necessary as well as an agreement as to which PA guidelines should be used.

Abstract
PURPOSE Physical activity (PA) is an important outcome in lung cancer; however, there is lack of consensus as to the best method for assessment. The Physical Activity Scale for the Elderly (PASE) is a commonly used questionnaire. The aim of this study was to assess the clinimetric properties of the PASE in lung cancer, specifically validity, predictive utility and clinical applicability (floor/ceiling effects, responsiveness and minimal important difference [MID]). METHODS This is a prospective observational study. Sixty-nine participants (62 % male, median [IQR] age 68 years [61-74]) with lung cancer completed the PASE at diagnosis at 2, 4 and 6 months. Additional measures included movement sensors (steps/day), physical function, health-related quality of life, functional capacity (6-min walk distance [6MWD]), and muscle strength. Spearman's rank correlation coefficient was used to assess relationships. Linear regression analyses were conducted to determine predictive utility of the PASE for health status at 6 months. Responsiveness (effect size) and MID (distribution-based estimation) were calculated. RESULTS The PASE was administered on 176 occasions. The PASE had moderate convergent validity with movement sensors (rho = 0.50 [95 %CI = 0.29-0.66], p < 0.005) and discriminated between participants classed as sedentary/insufficient/sufficient according to PA guidelines (p < 0.005). The PASE had fair-moderate construct validity with measures of physical function (rho = 0.57 [95 %CI = 0.46-0.66], p < 0.005), 6MWD (rho = 0.40 [95 %CI = 0.23-0.55], p < 0.005), and strength (rho = 0.37 [95 %CI = 0.18-0.54], p < 0.005). The PASE (at diagnosis) exhibited predictive utility for physical function (Bcoef = 0.35, p = 0.008) and quality of life (Bcoef = 0.35, p = 0.023) at 6 months. A small floor effect was observed (3 %); however, there was no ceiling effect. There was a small responsiveness to change (effect size = 0.23) and MID between 17 and 25 points. CONCLUSIONS The PASE is a valid measure of self-reported PA in lung cancer.

Abstract
SUMMARY Young adulthood is characterized by profound life-style changes. This study suggests that reduction of sport or exercise, induced by alteration of the occupational situation, negatively impacts generation/maintenance of peak bone mass. In order to compensate occupational-related reductions of physical activity, workplace exercise programs will be helpful. INTRODUCTION Only few studies have determined the effect of physical activity or physical exercise on bone mineral density (BMD) in the period of late skeletal maturation, i.e. around peak bone mass. The aim of this article was to determine the long-term effect of different levels of physical activity and exercise directly and indirectly derived by occupation during young adulthood. METHODS Sixty-one male and female dental students (DES) and 53 male and female sport students (SPS) 21±2 years old were accompanied over the course (4.8±0.5 years) of their study program. BMD at the lumbar spine (LS), hip, and whole body (WB) were determined using dual-energy X-ray absorptiometry. RESULTS Parameters of physical activity increased non-significantly in both groups with no relevant differences between the groups. Indices of exercise, however, increased significantly in the SPS group while a significant decrease was assessed for the DES group. Independent of gender, BMD of the SPS increased significantly (p≤0.007) at all skeletal sites (LS, 2.4±3.9%; hip, 1.6±3.5%; WB, 1.8±2.8%) while BMD of the DES remained unchanged at LS (-0.6±4.4%, p=0.432) and WB (0.5±1.9%, p=0.092) but decreased significantly at the hip (-1.9±4.3%, p=0.010). BMD-changes at LS, hip, and WB differ significantly between SPS and DES (p≤0.017). Results remained unchanged after adjusting for baseline BMD-values that differed (p=0.030 to p=0.082) in favor of the SPS group. CONCLUSION Changes of exercise levels directly or indirectly caused by occupational factors during young adulthood significantly affected generation and/or maintenance of peak bone mass. Compensatory exercise is thus highly relevant for bone health of young adults.

The international journal of behavioral nutrition and physical activity. 2015;:123
Abstract
BACKGROUND Young children are thought to be inactive in childcare, but little is known about location-specific activity levels. This observational study sought to describe the in-care and out-of-care activity patterns of preschool-aged children and explore differences in physical activity level by childcare attendance. METHODS Three to four-year-old children were recruited from 30 preschool and nursery 'settings' in Cambridgeshire, UK. Average minutes per hour (min/h) spent sedentary (SED), in light physical activity (LPA) and in moderate-to-vigorous PA (MVPA) were measured by accelerometry for up to 7 days (mean: 6.7 ± 1.1). Weekly childcare attendance patterns were reported by parents. The within-child association between childcare attendance and outcomes was assessed using two- and three-level hierarchical regression; sex by care (in/out) interactions were considered. RESULTS Two hundred and two children (51% female) had valid activity data for ≥2 days. Children, and particularly boys, were less sedentary and more active when in care compared to at home (SED: Boys: β (SE): -6.4 (0.5) min/h, Girls: -4.8 (0.5); LPA: Boys: 0.6 (0.4), Girls: 1.8 (0.4); MVPA Boys: 5.7 (0.5); Girls: 3.0 (0.4)). Differences between in-care and at-home activity were largest in the (early) mornings and early evenings for boys; no compensation in at-home activity occurred later in the day. On days when children were in care part-time (1-5 h) or full-time (>5 h), they were significantly less sedentary and more active compared with non-care days. CONCLUSIONS Young children, and particularly boys, accumulate more MVPA in care compared to at home. Future research should identify factors accounting for this difference and consider targeting non-care time in intervention efforts to increase higher-intensity activity and decrease sedentary time in preschoolers.

Abstract
INTRODUCTION Parks provide opportunities for physical activity for children. This study examined sex differences in correlates of park-based physical activity because differences may indicate that a standard environmental intervention to increase activity among children may not equally benefit boys and girls. METHODS The System for Observation Play and Recreation in Communities was used to measure physical activity among 2,712 children and adolescents in 20 neighborhood parks in Durham, North Carolina, in 2007. Sedentary activity, walking, vigorous park activity, and energy expenditure were the primary outcome variables. Hierarchical logit regression models of physical activity were estimated separately for boys and girls. RESULTS Type of activity area and presence of other active children were positively associated with boys' and girls' physical activity, and presence of a parent was negatively associated. A significant interaction involving number of recreation facilities in combination with formal activities was positively associated with girls' activity. A significant interaction involving formal park activity and young boys (aged 0-5 y) was negatively associated with park-based physical activity. CONCLUSION Activity area and social correlates of park-based physical activity were similar for boys and girls; findings for formal park programming, age, and number of facilities were mixed. Results show that girls' physical activity was more strongly affected by social effects (eg, presence of other active children) whereas boys' physical activity was more strongly influenced by the availability of park facilities. These results can inform park planning and design. Additional studies are necessary to clarify sex differences in correlates of park-based physical activity.

Micronutrient Deficiencies in Patients With Heart Failure: Relationships With Body Mass Index and Age.
Shetty, PM, Hauptman, PJ, Landfried, LK, Patel, K, Weiss, EP
Journal of cardiac failure. 2015;(12):968-72
Abstract
BACKGROUND It is conceivable that lean patients (body mass index 18.5-24.9 kg/m(2)) with heart failure (HF) have low body weight due to low food consumption and that this may contribute to micronutrient deficiencies and to their poorer prognosis compared with overweight/obese patients. We hypothesized that lean patients have a greater number of inadequate micronutrient intakes (<50% of recommendations) than overweight/obese patients and that this also depends on age. METHODS AND RESULTS Lean (n = 15) and overweight/obese (n = 49) patients underwent 24-hour diet and physical activity recall interviews. Inadequate essential micronutrient intakes were ubiquitous (intakes of 13 ± 1 of 27 micronutrients were inadequate) and did not depend on race, status, or access to supermarkets. Younger (40-64 y) lean patients had inadequate intakes of 20 ± 2 micronutrients, which was more than the other weight/age subgroups (all P < .01). Physical activity levels did not differ across weight and age groups. CONCLUSIONS Patients with HF may be at risk of malnutrition due to numerous inadequate micronutrient intakes; younger lean patients may have an especially high risk. Future studies are needed to confirm these preliminary findings and to investigate the possibility that incorporating a micronutrient-dense meal plan will improve patient outcomes.
