There is sufficient evidence to support the advice that HIV-positive patients should be encouraged to undertake regular exercise. They will experience a training effect dependent on the normal parameters of frequency, intensity, duration, and mode of exercise. It appears that the first bout of exercise will not detrimentally affect their immune status. Exercise can be tailored to meet individual requirements, which may vary from aerobic training to improve work capacity, to resistance training to improve strength and to maintain or gain weight.
Objective: The purpose of this study was to examine the effects of intrasession rest interval length on the development of quadriceps torque, work and power over a 6-week period of training. Subjects. Recreationally active men (N - 10) were randomly assigned to 1 of 2 groups: group 1 had a short interset rest interval (40 seconds), and group 2 a long interset rest interval (160 seconds).
Objective: To determine the influence of probenecid on the urinary excretion of androsterone as a representative of anabolic-androgenic steroids. Design: Twenty healthy, male volunteers participated in an open, single-dose, randomised, two-way, cross-over study with a drug-free interval of 7 days between treatment phases. Each subject received either a placebo or a single dose of 2 000 mg (4 x 500 mg) probenecid tablets once in a randomised order.
Objective: To assess whether partial as opposed to complete anterior cruciate ligament (ACL), rupture causes changes in quadriceps and hamstring muscle size or, strength. Methods: Thirteen complete (COMP) and 5 partial (PART) ACL-deficient subjects, whose injuries were diagnosed by magnetic resonance imaging (MRI), completed the trial.
Objective: To determine the training habits of top age group runners in the Two Oceans 56 km race. The specific questions of the study were: (i) were there gender differences in training habits of the top runners; (ii) was there a relationship between training volume and running performance at different distances; and (iii) did the older runners train differently from the younger runners? Design: A questionnaire study where the top 10 runners (male and female) in each of the 11 age groups were selected.
