The personal health behaviours, including physical activity, of healthcare professionals influence their counselling practices as they relate to non-communicable diseases (NCDs). However, despite the importance of producing healthy, physically active graduates, there are limited data on the physical fitness of future healthcare professionals. This cross-sectional observational study determined the prevalence of below-average fitness in the four components of fitness in first-year university medical students. 152 participants (46 male, 106 female, 20.16 ± 2.69 years) completed cardiorespiratory fitness tests (submaximal step test), flexibility (sit-and-reach test), muscle strength (handgrip), and muscle endurance tests (sit-ups, push-ups). Sex differences were reported using one-way ANOVA or Chi square test and significance was set at p < 0.05. The prevalence (%) of below-average fitness was 69.54% for cardiorespiratory, 25.66% for handgrip strength, 65.79% for sit-ups, 23.03% for push-ups and 7.24% for flexibility. Physical fitness parameters (mean±standard deviation (SD)) were compared between sexes, where it was found that females were more flexible than males (40.61 ± 8.40 cm vs 36.70 ± 9.31 cm, p = 0.012). Males had better handgrip strength (88.96 ± 12.04 kg vs 59.34 ± 10.36 kg, p < 0.001), muscle endurance sit-ups (33.46 ± 9.04 vs 24.48 ± 12.18, p < 0.001) and push-ups (30.28 ± 13.95 vs 24.27 ± 12.35, p = 0.009). First-year medical students have poor physical fitness, notably cardiorespiratory fitness and muscle strength, which are important markers for NCD risk assessment. Tertiary institutions training healthcare professionals should consider developing interventions to improve students' physical fitness thereby influencing their health, wellbeing, academic performance and future counselling practices.

Currently, there are five international screening tools that are recommended to identify individuals who require pre-exercise medical clearance to reduce the risk of medical encounters during exercise. Therefore, the aim was to determine the percentage of race entrants who are advised to obtain pre-exercise medical clearance and the observed agreement between these five different international pre-exercise medical screening tools. In all, 76,654 race entrants from the Two Oceans Marathon (2012–2015) that completed an online pre-race screening questionnaire. Five pre-exercise medical screening tools (American Heart Association (AHA), pre-2015 American College of Sport Medicine (ACSM), post-2015 ACSM, Physical Activity Readiness Questionnaire (PAR-Q), and the European Association of Cardiovascular Prevention and Rehabilitation (EACPR)) were retrospectively applied to all participants. The % (95%CI) race entrants requiring medical clearance identified by each tool and the observed agreement between tools (%) was determined. The % entrants requiring medical clearance varied from 6.7% to 33.9% between the five tools: EACPR (33.9%; 33.5–34.3); pre-2015 ACSM (33.9%; 33.5–34.3); PAR-Q (23.2%; 22.9–23.6); AHA (10.0%; 9.7–10.2); post-2015 ACSM (6.7%; 6.5–6.9). The observed agreement was highest between the pre-2015 ACSM and EACPR (35.4%), for pre-2015 ACSM and PAR-Q (24.8%), PAR-Q and EACPR (24.8%), and lowest between the post-2015 ACSM and AHA (4.1%). The percentage of race entrants identified to seek medical clearance (and observed agreement) varied considerably between pre-exercise medical screening tools. Further research should determine which tool has the best predictive ability in identifying those at higher risk of medical encounters during exercise. [ABSTRACT FROM AUTHOR]

The prevalence of childhood obesity is increasing in South Africa and can be linked to decreased physical activity (PA). It is important to be able to accurately measure children's PA levels as part of a holistic strategy for maintaining healthy body weight. The primary aim of this study was to determine whether children in grades two and three can self-report PA by means of a questionnaire. Fifty-eight participants (girls=28; boys=30) from a primary school in Gauteng were recruited for the study. The participants had to wear a pedometer (Omron HJ-720) for seven days after which they completed the Physical Activity Questionnaire for older Children (PAQ-C). The average steps per day were 9289, with weekday steps (10,219) being more than weekend steps (6,795). The mean score for the PAQ-C was 3.14±0.47. There was a significant moderate correlation (r=0.49; p<0.01) between the overall PAQ-C score and average steps per day. The PAQ-C can be an effective way to gain insight into the PA levels in children but should not replace objective measures of PA. The participants in this study appear to be accumulating insufficient PA over the course of the week. [ABSTRACT FROM AUTHOR]
