Biography: Dr Erasmus has been lecturing full time at the University of Zululand since 2017. He integrates his experience as biokineticist in the private sector (14 years) and sport coach (24 years) into his teaching philosophy to show students the relevance of theoretical knowledge in practical job-related situations. He holds a PhD, MSc, Hons. BSc and BSc degree from the University of North-West (formerly PU for CHE). His research interests are in the field of developing sport talent, while correcting biomechanical deficiencies and preventing injuries, as well as method to advance further education in sport and exercised related professions. He thus creates a conducive environment to apply his Teaching philosophy through: practical demonstrations, case study scenarios and work integrated learning. He strives to develop a global competent graduates: “our students should be informed of current local and international trends in the medical and physical education field so that they can develop into entrepreneurs who can adapt to the South African environment as well as the “digital world”.

    Associations between arterial stiffness and cardiovascular disease risk factors among black South African children
    2021
     | Health and Medical P...
    Background A limited number of studies have researched the associations between conventional cardiovascular disease (CVD) risk factors and arterial stiffness in children. Objectives To explore the associations between specific conventional CVD risk factors and arterial stiffness in black South African (SA) children. Methods This cross-sectional study included 59 children (male:17; female:42). The mean age (and associated standard deviation) of the participants was 11.15 (1.40) years. Conventional CVD risk factors included body mass index (BMI), waist circumference (WC), hip circumference, systolic blood pressure (SBP), resting heart rate (RHR), peak oxygen consumption (VO2peak) and physical activity. Pearson’s correlation was used to measure associations between arterial stiffness, expressed as the stiffness index (SI), and CVD risk factors. Hierarchical multiple regression analysis adjusting for age was performed to identify associations between the independent variables (VO2peak, SBP, BMI, physical activity, RHR and WC) and the dependent variable (SI). Results Arterial stiffness was found to be significantly positively correlated with age (r=0.52; p=0.03) and significantly negatively correlated with VO2 peak (r= –0.53; p=0.03) in male participants. Following regression analysis, the association with age (r2=0.27; p=0.03) and SI remained significantly independent. When means were combined across the two gender groups, age (r=0.27; p=0.04) and RHR (r=0.26; p=0.05) were found to be significantly positively correlated with SI. Following regression analysis, both age (r2=0.07; p=0.04) and RHR (r2=0.15; p=0.02) remained significantly independently associated with SI. Conclusion Age and RHR appear to be strong predictors of arterial stiffness in black SA children.
