The purpose of this study was to determine whether there are differences between racial groups for body mass, stature and body mass index (BMI) in South African elite U18 rugby players and whether there were significant changes in these measurements between 2002 and 2012. Self-reported body mass and stature were obtained from U18 players (n = 4007) who attended the national tournament during this period. BMI was calculated for each player.White players were 9.8 kg heavier than black players, who were 2.3 kg heavier than coloured players (P < 0.0001). The body mass of all groups increased from 2002 to 2012 (P < 0.0001). White players were 7.0 cm taller than black players who were 0.5 cm taller than coloured players (P < 0.0001). Players’ stature measurements did not change significantly during the study period. The average BMI of white players was 0.9 kg·m^?2 greater than black players who were on average 0.7 kg·m^?2 greater than coloured players (P < 0.0001). The BMI of all groups changed similarly over the study period. The body mass, stature and BMI of elite under-18 rugby players in South Africa were significantly different between racial groups. This has implications for transforming the game to make it representative of the South African population.  相似文献

Running intensity as determined by heart rate is the same in fast and slow runners in both the 10‐ and 21‐km races     

E.A. Selley  T. Kolbe  C.G. Van Zyl  T.D. Noakes  M.I. Lambert 《Journal of sports sciences》2013,31(5):405-410

The aims of this study were to determine (1) whether running speed is directly proportional to heart rate (HR) during field testing and during 10‐ and 21‐km races, and (2) whether running intensity, as estimated from HR measurements, differs in 10‐ and 21‐km races and between slow and fast runners at those running distances. Male runners were divided into a fast (65–80 min for 21 km; n = 8) or slow (85–110 min for 21 km; n = 8) group. They then competed in 10‐ and 21‐km races while wearing HR monitors. All subjects also ran in a field test in which HR was measured while they ran at predetermined speeds. The 10‐km time was significantly less in the fast compared with the slow group (33:15 ± 1:42 vs 40:07 ± 3:01 min:s; x ± s.d.), as was 21‐km time (74:19 ± 4:30 vs 94:13 ± 9:54 min:s) (P < 0.01). Despite the differences in running speed, the average running intensity (%HR_max) for the fast and slow groups in the 10‐km race was 90 ± 1 vs 89 ± 3% and in the 21‐km race 91 ± 1 vs 89 ± 2%, respectively. In addition, %HR_max was consistently lower in the field test at the comparative average running speeds sustained in the 10‐km (P < 0.01) and 21‐km (P < 0.001) races. Hence, factors in addition to work rate or running speed influence the HR response during competitive racing. This finding must be considered when running intensity for competitive events is prescribed on the basis of field testing performed under non‐competitive conditions in fast and slow runners.  相似文献   

Muscle Fiber Type Composition and Knee Extension Isometric Strength Fatigue Patterns in Power- and Endurance-Trained Males

Abstract

Muscle fiber type composition in the vastus lateralis and knee extension isometric strength fatigue patterns were assessed in eight endurance-trained and eight power-trained males. Two different 25-trial isometric contraction exercise regimens were administered: a 10-second contraction, 5-second intertrial rest condition designed to induce a fast rate of fatigue and a 10-second contraction, 20-second intertrial rest condition designed to induce a slower rate of fatigue. The power group fatigued almost four times faster than the endurance group in the 10:5 exercise condition. In the 10:20 exercise condition, the endurance group showed no fatigue pattern while the power group had a significant strength decrement of 32%. In both exercise conditions, the power group exhibited more complex fatigue patterns in terms of statistically significant trend components. Maximum isometric strength correlated positively with slow twitch (ST) percent number in power (r = .80) and endurance (r = .48) groups, but negatively with linear trend coefficients in endurance (r = -.62) and power (r = -.80) groups. Maximum isometric strength also correlated higher with fatigue curve trend coefficients than did muscle fiber type composition. Thus, a faster rate of fatigue was associated with higher maximum isometric strength and with higher ST percent number and area. Since maximum isometric strength correlated with body weight (r = .86 for groups combined), both maximum isometric strength and muscle mass appear to be more important determinants of knee extension isometric strength fatigue patterns than muscle fiber type composition.  相似文献   

Children's drawing and painting from a cognitive perspective: a longitudinal study     

E. Beverley Lambert 《Early Years: An International Journal of Research and Development》2005,25(3):249-269

This paper describes a longitudinal study undertaken with 40 pre‐schoolers during their last six months in an early childhood centre and their first six months at school. The study presents an investigation of the pathways that child drawers and painters make towards representational depictions. As such its primary focus is on cognitive processes. Monthly samples of 40 children's drawings and paintings were collected over a 12‐month period that included the children's transition into formal schooling. CrossTabs analysis showed that the relevant cognitive abilities tended to present in clusters and that patterning may be a serious component both in its own right, as well as in facilitating representational depictions, as previously claimed by Booth.  相似文献   

Quality of Life of Higher Education Students with Learning Disability Studying Online     

David C. Lambert 《International Journal of Disability, Development & Education》2018,65(4):393-407

This study examined how learning challenges encountered within online learning environments affected the quality of life of students with learning disability. A qualitative content analysis of semi-structured interviews conducted with eight students (mean _age = 33.75 years; SD = 8.15), revealed that learning challenges had consequences on students quality of life with regards to levels of stress/anxiety, self-esteem, time available for other activities, personal relationships and financial pressures. A notable finding was that these quality of life concerns were frequently associated with the extra time and effort students invested in their studies as a way of managing the learning challenges encountered. The findings of this study provide valuable insights into the higher levels of anxiety and lower levels of self-esteem previously reported for students with learning disability; and underscore the importance of minimising learning barriers, providing study accommodations, and providing multifaceted support programmes that address both academic and emotional/personal concerns.  相似文献

The effect of a prophylactic dose of flurbiprofen on muscle soreness and sprinting performance in trained subjects.   总被引：5，自引：0，他引：5

The aim of this study was to examine the effects of a prophylactic dose of a local, transcutaneously administered, non-steroidal anti-inflammatory drug on muscle soreness, muscle damage and sprinting performance in young trained males. Twenty-five subjects aged 19+/-3 years, actively participating in rugby union and field hockey, were familiarized with the test procedure and then divided at random into an experimental group (n = 13) and a control group (n = 12). The experimental group received two patches, each containing 40 mg flurbiprofen (TransAct LAT), 12 h before an exercise bout designed to produce delayed-onset soreness (DOMS). The control group received identical non-medicated placebo patches at the same time. Delayed-onset muscle soreness was induced by an exercise protocol consisting of drop jumps (seven sets of 10 repetitions). Serum creatine kinase activity, muscle soreness, muscle girth and acceleration in a maximal sprint over 30 m were measured before the induction of DOMS and at 12, 24, 48 and 72 h thereafter. Plasma lactate concentration was measured 3 min after the 30-m sprint tests. Subjects in both groups had significantly more pain at 24 and 48 h compared with at 12 and 72 h (P < 0.05; Friedman two-way analysis of variance). Thigh girth and serum creatine kinase did not change throughout the experiment. Although plasma lactate concentrations were elevated after the 30-m sprint, there were no differences between groups or as a result of DOMS. The greatest acceleration occurred between 5 and 10 m. This was not affected by the anti-inflammatory drug or DOMS. In conclusion, the aetiology of the DOMS induced in the trained subjects in this study seems to be independent of inflammatory processes or, more specifically, of increases in prostaglandin synthesis in the muscles.  相似文献
