Biokinetics, Exercise and Leisure Sciences Team at National Conference
Five studies conducted by a team of four academics and students from UKZN’s Discipline of Biokinetics, Exercise and Leisure Sciences (BELS) were presented at this year’s South African Sports Medicine Association (SASMA) Congress in Johannesburg.
Senior Lecturer, Dr Jeanne Grace, presented her study which analysed the electrocardiographic patterns in South African students of Zulu descent who represented UKZN in boxing (endurance modality) and body building (resistance modality) at a regional level.
‘Similar to findings in other ethnic Africans, a large proportion of the Zulu study population displayed ECG criteria indicative of left ventricular hypertrophy on the evidence of a marked increase of R5/S1-wave voltage and ST/T-segment changes with no differences in relation to whether they participate in strength or endurance related sport,’ said Grace.
Lecturer Dr Takshita Sookan presented two studies on the effect of a progressive resistance training programme and on whey protein intake on the quality of life in human immunodeficiency virus-infected individuals receiving antiretroviral therapy. One of these was a poster presentation and the other presented orally. Sookan commented that exercise training was an inexpensive and effective strategy for improving the quality of life in this population which could impact other facets of their lives.
A study by masters candidate, Ms Jaymie Donaldsons, investigated the effect on athletes of protein supplementation taken before sleep, post a bout of resistance exercise. The study aimed to measure performance and recovery the following day in athletes. Donaldsons reported that Casein supplementation – a milk protein extract recognised for its excellent amino acid profile, slow digestion, and interesting peptides – consumed 30 minutes prior to sleep enhanced the perception of recovery the next morning from a bout of strenuous resistance training in athletes.
Ms Jessica Köhne said: ‘Exercise-induced muscle damage can result in reduced muscle force, increased muscle soreness, increased intramuscular proteins in the blood, and reduced performance.’ Her study investigated the potential effects of the ingestion of a multi-ingredient supplement on markers of muscle damage and inflammation following a single 60-minute bout of downhill running in trained female runners.
‘Multi-ingredient supplementation did not reduce muscle damage and inflammation compared with an isocaloric placebo, although the bout of DHR did elicit changes in muscle damage and inflammatory markers in trained female runners that were returned to baseline by 72 hours,’ Köhne reported.
Another masters student, Ms Samantha Joe Ballington, won the conference lucky draw to attend the 2016 American College of Sports Medicine Conference in Boston.
The BELS team said the SASMA Conference was always a highlight for both staff and students in the field. ‘This year’s conference was no exception. There were high calibre national and international speakers and it is a great opportunity to network and learn about first-hand innovative research within our field.’
