The aim of the present study was to determine the effect of 4 weeks high intensity intermittent Taekwondo (TKD) training program on body composition, physical fitness and performance of South African TKD athletes of Zulu ancestry. Thirty four (n=34) active TKD athletes aged 20–26 years volunteered for this study. The athletes were divided into control and experimental groups. The control participants (10 males and 7 females) were holders of green and lower belts with provincial exposure. The experimental group (10 males and 7 females) had blue or senior belts who qualified to represent the provincial club and to compete in International championships. Both groups were subjected to a 4 week of TKD and strength training. The experimental group performing high intensity intermittent (85–95%VO2max) training and control group performing interval TKD training of lower intensity (70–75% VO2max). All subject were pre and post-tested on body composition [body mass, BMI, body fat percentage (%BF), sum of 6 skinfolds (SS)], flexibility (sit & reach), leg power (standing broad jump), muscle strength and endurance (sit-ups and push-ups), and agility (T-test) and VO2max (20 m bleep test). Resting heart rate (RHR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured. Data was analyzed using paired t-test for independent samples and Z-score individual radar plots statistics. After 4 weeks of training, athletes in the experimental group showed a reduction in body weight (p<0.05), BMI (p<0.001), SBP (p<0.05), RHR (p<0.05), SS (p<0.05), and fat % (p<0.001) and improvement (p<0.001) in flexibility, muscle strength, power, agility and VO2max. In male controls, fat % was decreased (p<0.05), flexibility and VO2max were increased (p<0.05). In female controls, only flexibility was improved (p<0.05). The findings of this study support the effectiveness of 4 weeks high intensity intermittent training in Taekwondo athletes of Zulu ancestry improves body composition, cardiorespiratory response and physical performance that could contribute to health and enhanced combat skills.
The female condom is the only current method for female partners to simultaneously prevent both pregnancy and sexually transmitted infections. Studies of various contraceptive methods suggest that providers’ acceptance and endorsement may be a key factor in their clients’ uptake and continued use of a method. Our aim in this study was to assess the relationship between nurses’ knowledge of and their willingness to promote female condom use in 18 public healthcare facilities within the Johannesburg District. The mean score of correct answers of 398 nurses completing an anonymous, self-administered, six-item questionnaire was 4 out of a maximum of 6. Data analysis included the use of descriptive statistics and a chi-square test. It was found that 79% of participants were knowledgeable but only 59% were willing to promote female condom use. There was no association between knowledge of and willingness to promote female condom use. The following significant associations with knowledge and willingness to promote female condom use were found: family planning experience, being employed by a local government authority, working in a primary care clinic and having had informal training on female condom use. Informal training of nurses within the family planning unit in the clinics has the potential to improve nurses’ knowledge and willingness to promote female condom use. Significance: • This is the first study conducted in South Africa on the knowledge of and willingness of healthcare providers to promote female condom use. • An effective strategy is needed to motivate healthcare workers to promote female condom use with their patients. • Informal training of nurses within the family planning unit has the potential to improve nurses’ knowledge of and willingness to promote female condom use.
ance (60-second sit-ups and 2 minutes push ups), explosive leg power (vertical jump), agility (T-test), aerobic power (20 m bleep test) converted to maximum oxygen uptake (VO 2max) were measured. Data were analysed with t-test for independent samples and Z-score individual radar plot statistics for each athlete. Results: There was no significant difference in agility between juniors (10.9 ±0.4s) and seniors (12.6 ± 1.2s) (p>0.05). The seniors showed significant (p<0.05) higher values in sit ups (
sit-ups and 2minutes push ups), explosive leg power (vertical jump), agility (t-test), aerobic power (20 m bleep test) converted to maximum oxygen uptake (VO 2max) were measured. Data were analysed using t-test for independent samples and Z-score individual radar plots statistics for each athlete. Results: There was no significant difference in agility between juniors (10.9 ±0.4s) and seniors (12.6 ± 1.2s) (p>0.05). The seniors showed significant of (p<0.05) higher values in sit ups (
Considering the global health threat posed by kidney disease burden, a search for new nephroprotective drugs from our local flora could prove a powerful strategy to respond to this health threat. In this study we investigated the antihyperuricemic and nephroprotective potential of RA-3, a plant-derived lanosteryl triterpene. The antihyperuricemic and nephroprotective effect of RA-3 was investigated using the adenine and gentamicin induced hyperuricemic and nephrotoxicity rat model. Following the induction of hyperuricemia and nephrotoxicity, the experimental model rats (Sprague Dawley) were orally administered with RA-3 at 50 and 100 mg/kg body weight, respectively, daily for 14 days. Treatment of the experimental rats with RA-3, especially at 100 mg/kg, effectively lowered the serum renal dysfunction (blood urea nitrogen and creatinine) and hyperuricemic (uric acid and xanthine oxidase) biomarkers. These were accompanied by increased antioxidant status with decrease in malondialdehyde content. A much improved histomorphological structure of the kidney tissues was also observed in the triterpene treated groups when compared to the model control group. It is evident that RA-3 possesses the antihyperuricemic and nephroprotective properties, which could be vital for prevention and amelioration of kidney disease.
