Governments have restricted public life during the COVID-19 pandemic, inter alia closing sports facilities and gyms. As regular exercise is essential for health, this study examined effect of pandemic-related confinements on physical activity (PA) levels. A multinational survey was performed in 14 countries. Times spent moderate-to-vigorous (MVPA) as well vigorous only (VPA) were assessed using Nordic Physical Activity Questionnaire (short form). Data obtained leisure occupational PA pre-...
Confinement measures during the COVID-19 pandemic have caused substantial reductions in global physical activity (PA) levels. In view of manifold health benefits PA, development interventions counteracting this trend is paramount. Our survey with 15,261 participants (38 ± 15 years, 58.5% females) examined preferences towards digital home exercise programs 14 countries affected by COVID-19. More than two-thirds sample (68.4%, n = 10,433) indicated being interested exercise, and most were...
Background Over the last 30 years, South Africa has experienced four ‘colliding epidemics’ of HIV and tuberculosis, chronic illness mental health, injury violence, maternal, neonatal, child mortality, which have had substantial effects on health well-being. Using data from 2019 Global Burden Diseases, Injuries Risk Factors Study (GBD 2019), we evaluated national provincial trends progress towards important Sustainable Development Goal targets 1990 to 2019. Methods We analysed GBD estimates...
Most countries affected by the COVID-19 pandemic have repeatedly restricted public life to control contagion. However, health impact of confinement measures is hitherto unclear. We performed a multinational survey investigating changes in mental and physical well-being (MWB/PWB) during first wave pandemic. A total 14,975 individuals from 14 provided valid responses. Compared pre-restrictions, MWB, as measured WHO-5 questionnaire, decreased considerably restrictions (68.1 ± 16.9 51.9 21.0...
Public life restrictions associated with the COVID-19 pandemic caused reductions in physical activity (PA) and decreases mental somatic health. Considering interplay between these factors, we investigated effects of digital home exercise (DHE) during government-enforced lockdowns.A multicentre randomised controlled trial was performed allocating healthy individuals from nine countries (N=763; 523 female) to a DHE or an inactive control group. During 4-week main intervention, members engaged...
The COVID-19 pandemic led to a rapid shift remote working, which affected ergonomic conditions and increased the risk of upper body musculoskeletal pain (MSP). This study assessed prevalence impact MSP (affecting head, neck, shoulders, back) among academic staff at University Technology during pandemic. Data were collected from 110 participants through an online, descriptive, cross-sectional survey adapted Dutch Musculoskeletal Questionnaire, Standardized Nordic McCaffrey Initial Pain...
Walking is recognized as an easily accessible mode of physical activity and therefore supported a strategy to promote health well-being. To complement walking, pedometers have been identified useful tool for monitoring ambulatory activity, typically measuring total steps/day. There is, however, little information concerning dose-response outcomes in relation intensity or duration sustained steps. We aimed examine this relationship, along with factors that mediate it, among employed adults.
Pedometer-based recommendations for accumulating steps/d largely focus on volume, with less emphasis intensity and fitness/health outcomes. We aim to examine this relationship.A convenience sample (N = 70, 35 men, 32 ± 8yrs) wore a pedometer (4 days). The classified steps as "aerobic" (≥ 60 steps/minute, minimum duration of 1 minute) or "non-aerobic" (< steps/minute and/or < minute). Estimated maximal oxygen uptake (VO2max), derived from 12-minute submaximal step-test, health outcomes: blood...
Insufficient PA has been shown to cluster with other CVD risk factors including insufficient fruit and vegetable intake, overweight, increased serum cholesterol concentrations elevated blood pressure. This paper describes the development of Working on Wellness (WOW), a worksite intervention program incorporating motivational interviewing by wellness specialists, targeting employees at risk. In addition, we describe evaluation effectiveness among for cardiovascular disease. The mapping (IM)...
Brisk walking is recommended as a form of health-enhancing physical activity. This study determines the steps/minute rate corresponding to self-paced brisk (SPBW); predicted for moderate activity (MPA) and comparison 2 findings.A convenience sample (N = 58: 34 men, 24 women, 31.7 ± 7.7 yrs), wearing pedometers heart (HR) monitor, performed SPBW 10 minutes 5 indoor sessions, regulated by metronome (ranging from 60-120 steps/minute). Using HR data trials, MPA was predicted. Adjustments were...
In March 2020, the SARS-CoV2 pandemic emerged in South Africa (SA). Due to highly contagious nature of this virus, government employed lockdown restrictions decrease rate infections and deaths. These prohibited use shared exercise facilities, which inadvertently decreased opportunity for physical activity (PA). This article provides a sub-analysis SA dataset within worldwide ASAP study, specifically focusing on compliance with guidelines World Health Organisation (WHO) SA. The study utilised...
Physical activity (PA) has been identified as a central component in the promotion of health. PA programs can provide low cost intervention opportunity, encouraging behavioral change while worksites have shown to be an appropriate setting for implementing such health programs. Along with these trends, there emergence use pedometers self-monitoring and motivational aid PA. This study determines effectiveness worksite program comprising 10-week, pedometer-based ("Steps that Count!"),...
Background: Many governments have restricted public life during the COVID-19 pandemic. Related measures, among others, include closures of sports facilities and gyms. As regular movement is essential for immune function, bodily health mental wellbeing, this study examined effect pandemic-related confinements on global physical activity (PA) levels.Methods: A multinational survey was performed in 14 countries. To quantify self-reported PA, times spent moderate vigorous activities (MVPA) as...
Background. The emergence of the pedometer as a useful motivational aid for increasing physical activity (PA) has supported its use in PA interventions. Objectives. To examine feasibility 10-week pedometer-based intervention complemented by regular messages, to increase ambulatory PA; and determine minimum sample size required randomised, controlled trial (RCT). Methods. Participants, sourced convenience sampling employees from an academic institution, were randomly assigned either group...
Background. The administration of intravenous contrast media (IVCM) is one the key areas currently under investigation for inclusion in South African (SA) radiographers’ scope practice. However, radiographers to legally administer IVCM, training guidelines must first be identified, developed and accredited by Health Professions Council SA. Objective. To investigate radiologists’ perspective knowledge, skills medicolegal required IVCM provide input development national guidelines. Methods. A...
Background:Wheelchair basketball has gained worldwide popularity over recent years. Several studies have demonstrated a high prevalence of injuries amongst wheelchair players. Few studies, however, investigated musculoskeletal pain in the context different point classifications – an integral part wheelchairsport. Objectives:The aim this study was to determine players South Africaand provide information on patterns distribution relation classification. Methods:Forty-eight players,...
Antenatal care (ANC) is crucial to reducing maternal and neonatal deaths, but few studies examined adolescent girls' young women's ANC utilisation knowledge in Ghana.
Background: Online home exercises represent opportunities to increase physical activity levels. However, high dropout rates are commonly reported in such programmes. This study aimed investigate the predictors of dropping out from an online exercise programme. Methods: A total 760 individuals nine countries participated this 8-week prospective cohort derived a randomised controlled trial. The participants were into "4-week live-streamed –>4-week recorded exercise" or no intervention...
