Objective. The aim of this study was to describe the body composition, strength and speed characteristics of elite junior South African rugby players. Design. Cross-sectional. Setting. Field study. Subjects. Rugby players (16 and 18 years old, N = 174) selected for the South African Rugby Union National Green Squad. Outcome measures. Body composition, 10 m and 40 m speed, agility, 1RM bench press, underhand pull-ups, push-ups, multistage shuttle run. Results. The under-16 players were on average shorter (175.6 ± 5.7 v. 179.2 ± 6.7 cm), weighed less (76.5 ± 8.2 v. 84.8 ± 8.3 kg) had less upper body absolute strength (77.1 ± 11.8 kg v. 95.3 ± 16.7 kg) and muscular endurance (41 ± 12 v. 52 ± 15 push-ups) and aerobic fitness (87.1 ± 19.4 v. 93.5 ± 15.3 shuttles) than the under-18 players. There were no differences in body fat, sprinting speed (10 m and 40 m) or agility between the two age groups. There were differences between playing positions, with the props having the most body fat, strongest upper bodies, slowest sprinting speed, least agility and lowest aerobic capacity compared with players in the other positions. Conclusion. This study provides data for elite junior rugby players and can be used to monitor the progression of players after intervention while also assisting with talent identification for the different playing positions.

Records kept by the Bauchi Meat Company, on 2,264 cattle slaughtered for meat, form 1982, were analysed to study the influence of season and year on the weight of the body, carcass, bone, wholesale and retail cuts, and dressing percentage. Bothe season and year showed significant (P < 0.01) influence on triats measured. Body weight was lowest during the rains (345.39 ± 3.00kg) increasing steadily thereafter to attain its highest peak (397.87 ± 3.30kg) in the hot-dry season. Body weight were similar in 1982 (370.63 ± 3.91kg) and 1984 (365.24 ± 2.39kg) but superior (P < 0.01) to that of 1983 (357.63 ± 2.61kg) Warm carcass weight was highest in the hot-dry season (217.11 ± 2.05kg) and lowest in the cod-dry season (181.64 ± 1.96kg). The annual values were similar for 1982 and 1984 but superior (P < 0.01) to that of 1983 (183.80 ± 1.43kg). The wholesale and retail cuts were heaviest in the hot-dry season. The dressing percentage was highest in the rainy season (56.13 ± 0.12%) and lowest (49.81 ± 0.21%) in the cold-dry season (P < 0.01). On annual basis carcasses dressed best in 1984. (55.26 ± 0.07%) and least (53.17 ± 0.12) in 1982. Studies such as this conducted through many season, years and even decades are valuable in functional planning.

Objective. We sought to determine the validity and reliability of a self-report physical activity questionnaire (PAQ) measuring physical activity/inactivity in South African schoolgirls of different ethnic origins. Methods. Construct validity of the PAQ was tested against physical activity energy expenditure estimated from an ACTIVITYGRAM and inactivity from reported television programme viewing in 332 girls (ages 9 - 12 yrs, grades 4 - 5). Body composition (WHO BMI percentiles and percentage body fat) was used as an indirect measure of validity for the PAQ. Test-retest reliability of the PAQ was assessed in a convenience sample of 14 girls. Results. Weak but significant associations were found between the body composition and PAQ-derived total energy expenditure (r=-0.18; p
