Segmented sedentary time and physical activity patterns throughout the week from wrist-worn ActiGraph GT3X+ accelerometers among children 7-12 years old

Background:This study examined the volume and patterns of physical activity(PA) and sedentary time(ST) across different segments of the week among boys and girls.Methods:A total of 188 children aged 7-12 years wore a wrist-mounted ActiGraph GT3 X+accelerometer for 7 days.Time spent in PA and ST was calculated using ActiLife software.The mean number of minutes of light PA,moderate PA,vigorous PA,moderate-to-vigorous PA(MVPA),and ST were calculated per weekday(before school,during school,and after school) and per weekend day(morning and afternoon-evening).Results:After school represented the greatest accumulation of ST compared with before school and during school segments.Boys engaged in225.4 min/day of ST(95% confidence interval(CI):216-235),and girls engaged in 222.2 min/day of ST(95%CI:213-231).During school,boys engaged in significantly more MVPA than girls(46.1 min/day(95%CI:44-48) vs.40.7 min/day(95%CI:39-43)).Across the whole weekday,boys participated in significantly more MVPA than girls(103.9 min/day(95%CI:99-109) vs.95.7 min/day(95%CI:90-101)).The weekend afternoon—evening segment represented the larger accumulation of ST,where boys were significantly more sedentary than girls(367.5 min/day(95%CI:353-382) vs.339.8 min/day(95%CI:325-355),respectively).Conclusion:Our findings suggest that children are highly sedentary and spend little of their time in school in MVPA,especially girls.Routine breaks in school elicit increases in light PA and MVPA.Future work should consider the use of more active breaks within school time to encourage PA and reduce ST.     

Twenty-four-hour movement guidelines during middle adolescence and their association with glucose outcomes and type 2 diabetes mellitus in adulthood

Purpose:The aim of the present study was to determine the association between adherence to the 24-h movement guidelines during middle adolescence and glucose outcomes(glycated hemoglobin and fasting glucose) and type 2 diabetes mellitus(T2DM) in adulthood,14 and 22 years later.Methods:We analyzed data from apparently healthy adolescents aged 12-18 years who participated in Waves Ⅰ and Ⅱ(1994-1996,n=14,738),Wave Ⅳ(2008-2009,n=8913),and Wave V(2016-2018,n=3457) of the National Longitudinal Study o...

Caution needed when interpreting muscle activity patterns during extremely low pedaling cadence

Dear editor,We noticed recent research that has just been published in Journal of Sport and Health Science(JSHS),comparing the muscular activity patterns in 1-and 2-legged cycling by Park and Caldwell.1 The authors reported that changes in muscle activities with 1-legged pedaling are due to a variety of changes in mechanical aspects of the pedaling motion,including altered crank torque patterns within the crank cycle,decreased pelvis stability,and the need for increased knee and ankle stiffness during the upstroke.The experiment was welldesigned and the discussion was fascinating.However,the testing protocol does not support the significance of the project,as stated in the first sentence of the abstract,“One-legged pedaling is of interest to elite cyclists and clinicians.”Their testing was conducted at 30 revolutions per min(rpm)and 30 watts(W),and both are too low for any kind of mechanical demand for cycling,either competitive sports or rehabilitation.The preferred cadences of experienced cyclists are approximately 85-95 rpm,whereas the most economic cadences are approximately 55-60 rpm.     

Incidence of injuries in professional snow sports: A systematic review and meta-analysis

Purpose:The study aimed to conduct a comprehensive systematic review and meta-analysis of injury incidence in professional skiers and snowboarders.Methods:We systematically searched PubMed,Web of Science,and MEDLINE for studies on injury incidence published from inception to April 2020.Injury data were extracted,alongside information on injury location,severity,type,cause,and sport discipline.Incidence of injuries was presented per 1000 athlete-days,with 95%confidence intervals(95%CIs).Results:The search identified 462 articles,and 22 were included in our review.The overall incidence of injuries among professional skiers and snowboarders was 3.49 per 1000 athlete-days(95%CI:2.97-4.01).Lower extremity had the highest injury incidence(1.54 per 1000 athletedays,95%CI:1.24-1.84).Incidence rates of slight,mild,moderate,and severe injuries were 0.26,0.31,0.57,and 0.59 per 1000 athlete-days,respectively.Contusion had the highest incidence rate(1.82 per 1000 athlete-days,95%CI:1.01-2.63).The most common cause of injury was contact trauma(3.20 per 1000 athlete-days,95%CI:1.32-5.08).Freestyle skiing had the highest incidence rate(6.83 per 1000 athlete-days,95%CI:4.00-9.66),and Nordic skiing had the lowest rate(2.70 per 1000 athlete-days,95%CI:1.94-3.46).Conclusion:Professional skiers and snowboarders have a substantial risk of sustaining injuries.Our findings can be used to inform the planning and provision of healthcare for elite participants in different snow sports.

Exercise interventions for older adults: A systematic review of meta-analyses

Background:The evidence concerning which physical exercise characteristics are most effective for older adults is fragmented.We aimed to characterize the extent of this diversity and inconsistency and identify future directions for research by undertaking a systematic review of metaanalyses of exercise interventions in older adults.Methods:We searched the Cochrane Database of Systematic Reviews,PsycInfo,MEDLINE,Embase,CINAHL,AMED,SPORTDiscus,and Web of Science for articles that met the following criteria:(1)meta-analyses that synthesized measures of improvement(e.g.,effect sizes)on any outcome identified in studies of exercise interventions;(2)participants in the studies meta-analyzed were adults aged 65+or had a mean age of 70+;(3)meta-analyses that included studies of any type of exercise,including its duration,frequency,intensity,and mode of delivery;(4)interventions that included multiple components(e.g.,exercise and cognitive stimulation),with effect sizes that were computed separately for the exercise component;and(5)meta-analyses that were published in any year or language.The characteristics of the reviews,of the interventions,and of the parameters improved through exercise were reported through narrative synthesis.Identification of the interventions linked to the largest improvements was carried out by identifying the highest values for improvement recorded across the reviews.The study included 56 meta-analyses that were heterogeneous in relation to population,sample size,settings,outcomes,and intervention characteristics.Results:The largest effect sizes for improvement were found for resistance training,meditative movement interventions,and exercise-based active videogames.Conclusion:The review identified important gaps in research,including a lack of studies investigating the benefits of group interventions,the characteristics of professionals delivering the interventions associated with better outcomes,and the impact of motivational strategies and of significant others(e.g.,carers)on intervention delivery and outcomes.     

Association of physical activity with risk of chronic kidney disease in China:A population-based cohort study

Background:Information on the association between physical activity(PA) and the risk of chronic kidney disease(CKD) is limited.We aimed to explore the associations of total,domain-specific,and intensity-specific PA with CKD and its subtypes in China.Methods:The study included 475,376 adults from the China Kadoorie Biobank aged 30-79 years during 2004-2008 at baseline.An interviewer-administered questionnaire was used to collect the information about PA,which was quantified as metabolic equivalen...     

Physical activity levels in American and Japanese men from the ERA-JUMP Study and associations with metabolic syndrome

Background:Metabolic syndrome(MetS) is a global health problem.Physical activity(PA) is a known modifiable risk factor for MetS and individual MetS components.However,the role of PA could differ between sub-populations due to differences in the variability of PA and other MetS risk factors.To examine these differences,multi-country studies with standardized outcome measurement methods across cohorts are needed.Methods:Cross-sectional PA levels(total and domain specific) in healthy middle-aged(44-56 years) men in the Risk Factor Assessment among Japanese and U.S.Men in the Post-World War Ⅱ Birth Cohort(ERA-JUMP) Study(n=730;American:n=417;Japanese:n=313;from population-representative samples in Pittsburgh,Pennsylvania,USA,and Kusatsu,Shiga,Japan) were compared.The relationships between PA levels and MetS(overall and specific components) in/across the American and Japanese sub-cohorts(adjusting for age,smoking,and alcohol consumption)were also assessed using the same instruments(pedometer and validated questionnaire) to measure PA in both cohorts.Results:A total of 510 individuals provided complete data on PA(American:n=265;Japanese:n=245).The American cohort had significantly lower mean±SD steps/day(7878±3399 steps/day) vs.the Japanese cohort(9055±3797 steps/day)(p <0.001) but had significantly higher self-reported moderate-vigorous leisure PA(American:15.9(7.4-30.3) metabolic task equivalent hours per week(MET-b/week) vs.Japanese:4.0(0-11.3) METh/week,p <0.0001).In both sub-cohorts,each 1000 steps/day increase was associated with lower odds of having MetS(American:OR=0.90,95%CI:0.83-0.98;Japanese:OR=0.87,95%CI:0.79-0.95) and the individual MetS component of high waist circumference(American:OR=0.86,95%CI:0.79-0.94;Japanese:OR=0.87,95%CI:0.80-0.95).In the American cohort only,higher self-reported leisure PA(Met-b/week) was associated with lower odds of MetS and high waist circumference(OR=0.98,95%CI:0.97-0.99 for MetS and waist circumference,respectively).Conclusion:Higher total step counts/day had an important protective effect on MetS prevalence in both the Japanese and American cohorts,despite differences in PA levels and other MetS risk factors.The effect of steps/day(across all intensity levels) was much greater than domainspecific moderate-vigorous PA captured by questionnaire,suggesting the need for measurement tools that can best capture total movement when examining the effects of PA on MetS development.     

The effects of resistance training on muscular strength and hypertrophy in elderly cancer patients: A systematic review and meta-analysis

Background:One of the most life-threatening comorbidities in elderly cancer patients is cancer cachexia,which is characterized by the ongoing loss of skeletal muscular strength and mass and is also associated with aging.There is a lack of recommendations for optimal resistance training(RT) for those patients.The purpose of this study was to systematically review and quantify the effects of RT on muscular strength and hypertrophy in elderly cancer patients.Methods: Five electronic databases were searched(until January 2020) for studies that met the following criteria:(i) cancer patients aged>60 years;(ii) structured and supervised RT intervention for>6 weeks;and(iii) measured muscular strength and/or hypertrophy.Results:Thirteen studies(717 participants,average age=66 years) met the inclusion criteria.RT significantly increased muscular strength(mean effect size=0.87,95% confidence interval(95%CI):0.43-1.32,p <0.001) and did not significantly induce muscle hypertrophy(mean effect size=0.09,95%CI:-0.14 to 0.31,p=0.45).In subgroup analyses for muscle strength,higher weekly frequency was significantly associated with larger effect size.Egger’ s test showed no significant publication bias for the 2 outcomes.Conclusion:The results suggest that RT improves muscular strength but does not significantly induce muscle hypertrophy in elderly cancer patients.

Neurophysiological correlates of interference control and response inhibition processes in children and adolescents engaging in open- and closed-skill sports

Background:Accumulating evidence suggests that sports participation promotes the development of inhibitory control,but the influences of the sports category and inhibition type still remain unclear.The categorization of sports based on the open-skill(externally paced)and closed-skill(self-paced)continuum allows for the integration of the environment as a factor contributing to sports-related benefits for inhibitory control.Methods:Cross-sectional data from different studies were combined(n=184)to examine the association between open-and closed-skill sports and cognitive control processes related to interference control and response inhibition.Participants(aged 9-14 years)filled in 7-day physical activity recall protocols and completed a Stroop Color-Word or a Go/NoGo task.The N200,N450,and P300 components of event-related potentials elicited by these tasks were recorded using electroencephalography.Results:Partial correlations supported the belief that time spent in open-skill sports was related to higher performance on inhibition trials.Additionally,path analyses revealed an association between this sports type and a greater negativity in the N200 and N450 amplitudes in both the full sample and group-level analyses.In contrast,no relation was found between sports type and P300 amplitude.Conclusion:The findings suggest that only the engagement in open-skill sports is associated with more effective conflict monitoring and higher performance on tasks demanding inhibitory control.     

The diagnostic and prognostic utility of the dual-task tandem gait test for pediatric concussion

Background:The tandem gait test has gained interest recently for assessment of concussion recovery.The purpose of our study was to determine the prognostic and diagnostic use of the single-and dual-task tandem gait test,alongside other clinical measures,within 10 days of pediatric concussion.Methods:We assessed 126 patients post-concussion(6.3§2.3 days post-injury,mean§SD)at a pediatric sports medicine clinic and compared them to 58 healthy controls(age:15.6§1.3 years;43%female).We also compared the 31 patients with concussion who developed persistent post-concussion symptoms(PPCS)(age=14.9§2.0 years;48%female)to the 81 patients with concussion who did not develop PPCS following the initial assessment(age:14.1§3.0 years;41%female).All subjects completed a test battery,and concussion patients were monitored until they experienced concussion-symptom resolution.The test battery included tandem gait(single-task,dual-task(performing tandem gait while concurrently completing a cognitive test)conditions),modified Balance Error Scoring System(mBESS),and concussion symptom assessment(Health and Behavior Inventory).We defined PPCS as symptom resolution time>28 days post-concussion for the concussion group.Measurement outcomes included tandem gait time(single-and dual-task),dual-task cognitive accuracy,mBESS errors(single/double/tandem stances),and symptom severity.Results:The concussion group completed the single-task(mean difference=9.1 s,95%confidential interval(95%CI):6.1-12.1)and dual-task(mean difference=12.7 s,95%CI:8.7
16.8)tandem gait test more slowly than the control group.Compared to those who recovered within 28 days of concussion,the PPCS group had slower dual-task tandem gait test times(mean difference=7.9 s,95%CI:2.0-13.9),made more tandem-stance mBESS errors(mean difference=1.3 errors,95%CI:0.2-2.3),and reported more severe symptoms(mean difference=26.6 Health and Behavior Inventory rating,95%CI:21.1-32.6).Conclusion:Worse dual-task tandem gait test time and mBESS tandem stance performance predicted PPCS in pediatric patients evaluated within 10 days of concussion.Tandem gait assessments may provide valuable information augmenting common clinical practices for concussion management.
