Risk Of Injury

The benefits of physical activity cross all domains of health. Unfortunately, many children are not meeting the current American College of Sports Medicine recommendations of 60 minutes of moderate to vigorous physical activity (MVPA) 7 days a week. This is especially deleterious since physical activity patterns during childhood may carryover to adulthood. Research has also shown that participating in one sport may increase the risk of injury. The purpose of this study was to examine self-reported exercise levels in children reporting to a tertiary sports medicine clinic over a three year period. Subjects were asked “How many minutes of moderate to vigorous physical activity per day?” and “How many days per week do you participate in moderate to vigorous physical activity”. Minutes per week of MVPA was calculated. Age, sex, and current sports and recreational activities were recorded. There were 7427 unique patients (53% female) with an average age of 13.8±2.6. The average minutes per day of exercise was reported as 85.6±44.4, average days per week was 4.4±1.6 and minutes per week was 410.8±266.9. Females reported less minutes per day (83.5 vs. 87.8, p<.001), less days per week (4.2 vs 4.7, p<.001) and less minutes per week (384.1 vs 440.2, p<.001) than males. On average, females reported 56 minutes less activity per week than their male counterparts. There were 3618 participants who only reported one activity and were categorized as specialized in a single physical activity. Those that specialized in a single activity were significantly older (14.1 vs 13.4, p<.001). There were no significant differences between reported minutes per day between specialized and unspecialized athletes (85.8 vs 85.2, p=.57). Those who specialized in one activity reported more days per week (4.6 vs 4.2. p<.001) and more minutes per week (423.8 vs 397.0, p=.001) than unspecialized athletes. Research has consistently shown that females are less active than males. Those who specialized in one activity participated in more minutes per week of activity, mainly through participating in more days of physical activity. Children should be encouraged to participate in a variety of activities on a daily basis to ensure they receive the benefits of physical activity.

Peak cardiorespiratory responses, physical activity patterns, and the association of VO2peak and physical activity were examined in 16 elementary (ES) and 16 high school (HS) females. Peak responses were assessed during treadmill running, and physical activity patterns were examined over two 12-hour weekdays. Results indicated similar relative VO2peak responses between groups (ES: M = 46.8 ml · kg−1 · min−1;HS:M = 46.6 ml · kg−1 · min−1). No statistical differences (p ≤ .05) were noted when moderate to vigorous physical activity (MVPA) and vigorous physical activity (VPA) were compared. Also, a three-way (Group × HR level × Sustained minutes) ANOVA revealed no statistical differences. A median correlation (r = .27) was found from 8 independent correlations of habitual physical activity and VO2peak. ES and HS appeared similar in regard to VO2peak, accumulative and sustained MVPA and VPA. Low levels of sustained MVPA and VPA (≥ 10 min) were evident in both groups.

Children’S Physical Activity

39 3- to 5-year-old children wore heart-rate monitors for 12 hr. on three consecutive days to examine physical activity patterns. Parent logs supplied additional information on type and location of activity. The highest number of accumulated minutes of moderate to vigorous physical activity was recorded during the weekday (38.6 min.) and weekend (31.4 min.) afternoons, a time period when more activity occurred outdoors. Sustained activity was mostly short in duration, but many children (71%) accumulated recommended amounts of activity on the weekday, fewer (46%) on the weekend. Spearman rank correlations for weekday ( r = .50, p = .004) and weekend ( r = .58, p = .004) activity were significant. Considering health risk factors associated with physical inactivity, early educators must look to the essence of young children's physical activity patterns in designing programs. Large motor activity that is intense and that occurs outdoors is a good place to start.

Objective In this study, we aimed to examine the association between physical activity patterns and sarcopenia in Arab men. Methods This cross-sectional study included 363 men (47.7 ± 15.4 years). We analyzed appendicular lean mass (ALM), handgrip strength test, and physical activity levels. ALM divided by height (meters) squared was calculated (ALM/Ht 2 ), and participants with −1 and −2 standard deviations below the sex-specific mean for Saudi young adults were considered to have sarcopenia class I and class II, respectively. Independent t-tests, analysis of variance, and Mann–Whitney U tests were performed to determine mean and median differences. Results We observed a significant difference between participants with and without sarcopenia in moderate-to-vigorous physical activity (MVPA); the correlation between ALM/H2 and MVPA was borderline significant. With a 1-hour/week increase in MVPA, ALM/Ht 2 increased by 0.30 kg/m2. Total and ALM, handgrip strength, and MVPA were significantly lower in participants age >60 years; fat mass and waist circumference were unchanged as compared with middle-aged participants. Conclusions We identified an association between time spent in recreational MVPA and lean muscle mass among Arab men. Future studies should examine the role of MVPA training programs on muscle mass and strength in older men.

The Impact

Abstract Background The primary objective of this study is twofold: (1) to examine the effect of COVID-19 safety measures, enacted to prevent transmission of SARS-nCOV-2, on total physical activity in the adult general population (≥ 18 years) and (2) to analyze the impact of the factor “severity of safety measures” on potential changes in physical activity. The secondary objective is to investigate the effects of safety measures on the respective PA intensities, i.e., sedentary behavior, light, moderate, and vigorous physical activity. Methods A systematic literature search will be performed in the following online databases: Medline (on Ovid), Web of Science, Scopus, L.OVE Coronavirus disease by Epistemonikos, and ProQuest Dissertations & Theses A&I. All obtained citations will undergo title and abstract as well as full-text screening by two independent reviewers. Observational studies investigating the effects of safety measures on physical activity patterns in the adult general population will be included. The standardized mean difference in total physical activity per time unit between pre- and during COVID-19 or between normative data and during COVID-19 will be the primary outcome. The standardized mean difference in sedentary time, light, moderate, and vigorous physical activity will be assessed as secondary outcomes. Eligible studies will be divided between the reviewers for data extraction using a pilot-tested data form. Risk of bias assessment will be performed using a standard assessment tool. If suitable, a random-effects meta-analysis and meta-regression with a unit of safety measure severity as the independent variable will be performed. Discussion This study will synthesize available data reporting the effect of COVID-19 safety measures on physical activity patterns in adults. Furthermore, we will incorporate a unit for the severity of safety measures for better generalizability of the results. These findings will be of great value for public health policymaking and estimating future health consequences. Systematic review registration PROSPERO CRD42021231039.

Abstract The purpose of this study was to examine the physical activity patterns of children with Down syndrome. A cross-sectional approach and accelerometry were used to measure the time children with Down syndrome (N  =  104) spent in sedentary, light, and moderate-to-vigorous physical activity. Results indicated that adolescents from ages 14 to 15 years were the most sedentary and spent the least amount of time in light and moderate-to-vigorous physical activity. A general trend of decreasing physical activity as children increase in age was found. This trend is similar to that found among typically developing youth. Participants in this study were found to spend a majority of their day engaged in sedentary activities. Results indicate that most participants were not accumulating the recommended 60 minutes of moderate or vigorous physical activity.

Background:Little is known about the physical activity patterns of Somali adolescents. This study compared time spent in moderate-to-vigorous physical activity (MVPA) and participation in specific physical activities among Somali, other Non-Hispanic black and white adolescents.Methods:A subsample of 1,268 adolescents (mean age= 14.6) who completed surveys as part of the EAT 2010 (Eating and Activity in Teens) study was included in analyses. Gender-stratified linear and logistic regressions, controlling for body mass index and demographic characteristics, were conducted to estimate mean weekly hours of self-reported MVPA and mean weekly hours and prevalence of engagement in each of 26 physical activities assessed by ethnic/racial group.Results:Somali girls had lower mean MVPA hours than their peers; however, no differences were found for Somali boys. Involvement in most activities was similar for Somali and other groups, but some differences were observed. For example, Somali youth were more likely to play soccer than their same-sex other black peers (boys: 52.4% vs. 20.4%; girls: 34.6% vs. 14.6%; P < .05). Somali girls also engaged in more hours per week of soccer than their black or white peers.Conclusions:Activities for which Somali youth indicated higher involvement may be particularly relevant for culturally-tailored physical activity programming.

Background:Childhood obesity has become a modern epidemic with escalating rates. The aim of our study was to identify physical activity patterns among Greek schoolchildren and to examine their relationship with obesity.Methods:700 adolescents age 10 to 12 years were evaluated through a standardized questionnaire. Several demographic, socioeconomic, and physical activity characteristics were recorded. Physical activity was assessed and adolescents were characterized as active and nonactive. Body height and weight were measured and body mass index was calculated in order to to classify subjects as overweight or obese (IOTF classification). Multiple logistic regression and multivariate techniques (principal components analysis) were performed.Results:Eight physical activity patterns were identified, including increased physical activity in weekdays and weekends, sports physical activity, vigorous, moderate, and low physical activity. Increased physical activity on weekends and vigorous physical activity in boys were negatively associated with being overweight or obese (OR: 0.65; 95% CI: 0.48−0.90 and OR: 0.66; 95% CI: 0.49−0.88, correspondingly) and moderate physical activity was marginally positively associated in girls (OR: 1.28; 95% CI: 0.97−1.69), after adjusting for several confounders.Conclusions:Our findings demonstrate the important role of vigorous physical activity in the maintenance of normal weight of adolescents
