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”.

    Combined aerobic and resistance training lowers body fat percentage in rural black South African women
    2021
     | Brieflands
    Background Obesity is currently one of the most dominating diseases affecting younger adults in South Africa. This is commonly caused by a poor lifestyle, which may lead to an increased risk of non-communicable diseases. Objectives The aim of the study was to examine if a six-week concurrent resistance and aerobic training program could elicit body composition and cardiorespiratory changes in rural black college women. Methods Forty sedentary black females (aged 18 - 25 years) were randomly assigned to a combined resistance and aerobic training (COM) group (n = 20) or a control group (n = 20). The COM group participated in four times weekly aerobic and resistance training. Aerobic training consisted of 30 minutes a session (week 1 - 3: cycling for 3 minutes at 60% heart rate reserve (HRR), followed by 2 minutes at 50% HRR; week 4 - 6: 3 minutes at 70% HRR, followed by 2 minutes at 60% HRR). Resistance training consisted of participants training at 50% of their one-repetition maximum (1-RM) for week 1 - 3, doing 3 sets of 15 repetitions; for week 4 - 6 at 60% 1-RM, doing 3 sets of 15 repetitions. Results Following the intervention, the COM group significantly (P ≤ 0.05) decreased their body fat percentage when compared to the control group (P = 0.006; d = 0.9), while no significant changes were observed in waist-to-hip ratio (P = 0.223) and cardiorespiratory endurance (P = 0.260) in either group. Conclusions Although body composition (especially waist circumference and body fat percentage) and cardiorespiratory fitness are recommended as the main targets of physical activity programs aimed at preventing CVD in college students, this study demonstrated that a six-week concurrent program improved body fat percentage, and not WHR and cardiorespiratory fitness, in sedentary rural college-aged females. Further, these findings suggest that one method of program design does not fit all populations and that exercise prescription should be targeted and not generalized.
