This study investigated the impact of Fundamental Motor Skills (FMS) on children’s Indigenous Games (IGs). Two hundred and three (203) children (Age: Mean=9.2; SD=1.322) from Camp and Tsiamo Primary Schools volunteered for the study. Following a pilot study, participants were assessed in koi, diphiri and dibeke indigenous games popular among Batswana children. Physical neuromotor tests measuring power, strength, speed, coordination and agility were also administered. Current findings were similar to previous studies done elsewhere. There was a weak relationship between fundamental motor skills in children’s indigenous games and the neuromotor fitness items. Key words: Indigenous games; Physical neuromotor performance; Fundamental movement skills.

The purpose of this study was to determine the influence of short-term creatine supplementation on sprint running performance (100 and 200 m) and circulating hormone [growth hormone (GH), testosterone and cortisol] concentrations. Twenty amateur male runners were randomly divided into a creatine supplementation group, or placebo group. Subjects were provided with capsules containing either creatine monohydrate or identical powdered cellulose placebo. Daily creatine monohydrate supplementation was 20 g/day parceled into three equal dosages to be consumed with each major meal. Subjects were tested for performance and resting blood hormone concentrations before and after six days. A double-blind research design was employed in this study. After this creatine loading, the mean running performance time of the creatine supplementation group decreased significantly in the 100 m, but not the 200 m. Serum GH, testosterone, and cortisol concentrations were not affected by creatine supplementation. It can therefore be concluded that although short-term creatine supplementation was found to improve sprint performance in the 100 m in amateur runners, this performance improvement did not appear to be hormonally mediated. Key words: Sprint performance; Creatine supplementation; Hormonal responses; Creatine loading.

A sample of 41 male student rugby players (mean age: 21.87 ± 1.39 years) completed the Recovery-Stress Questionnaire (Kellmann & Kallus, 2001), Athlete Burnout Questionnaire (Raedeke & Smith, 2001) and Stellenbosch Mood Scale (Terry et al., 2003) repeatedly over a five-month period. Independent t-tests, oneway analysis of variance and effect sizes were used to indicate significant differences between groups (categorised according to playing position, experience level and starting status). The group of forwards were shown to have significantly (d � 0.5) better results than the backline players for 12 of the 39 tested variables. The group of less experienced players had significantly less General and Sport-specific Stress and negative Mood State scores than their very experienced and novice counterparts, whilst the novice players showed greater General and Sport-specific Recovery scores. Differences in starting status were also observed as the reserve players were shown to have significantly higher General and Sport-specific Recovery scores and better Mood State scores than the regular starters. These results suggest that playing position, experience level and starting status should be considered in player management strategies and during the psycho-social monitoring of players aimed at reducing the onset and development of overtraining and burnout.

Football is probably the most popular game worldwide but there is still limited scientific information available concerning the physique and performance qualities of elite Indian footballers. Team games are sports where size, shape, body composition and fitness all play an important part in providing distinct advantages for specific playing positions. Hence an attempt has been made to study the various anthropometric parameters, motor ability and physiological profiles of the different Indian national club footballers and also to compare the above parameters with their international counterparts. The present study was carried out on one hundred fifty (150) male Indian footballers of six different national clubs of India including three from Kolkata (East Bengal, Mohan Bagan & Mohammedan Sporting) and other three from Goanese clubs (Salgaokar, Vasco & Dempo). The players were also sub-divided according to their specific field positions. Physical and physiological profiles including height, weight, percentage body fat (%BF), flexibility, agility, explosive power, and VO2 max were measured by standard procedures. It was noted that the mean values of age, height, weight and %BF were significantly different among footballers of different national clubs. Among the motor ability and physiological qualities only flexibility, agility and VO2 max were significantly different among the footballers of different national clubs (p<0.01). It was also observed that the mean values of height, weight, vertical jump and VO2 max of Indian national club players were found to be inferior to those of European, American and Australian footballers. However, the %body fat of Indian footballers according to their specific field positions was found to be comparable with their international counterparts. The defender, midfielder and striker of the present study were inferior in endurance (VO2 max) as compared to their international counterparts. Genetic factors may be the cause of smaller body size of the subject of the present study as compare to their international counterparts. So, it can be concluded that the differences among the footballers of present study with their international counterparts and specific playing position is probably the cause of hereditary factors and differences in activity in the game.

Perception of cohesion and imagery use among 45 elite team sport players in Botswana were assessed with the Group Environment Questionnaire (Carron et al., 1985) and the Sport Imagery Questionnaire (Hall et al., 1998) to determine whether a relationship exists between the variables, and whether imagery use will significantly predict team cohesion. Results of the correlation analysis revealed a significant (p .05) composite effect of imagery use on cohesion, while a shared variance of 6.7% was recorded for both variables. Furthermore it was revealed that Motivational Specific and Cognitive General imagery use were significant (p<.05) predictors of cohesion as perceived by the team players. Findings further suggest that the cognitive and affective elements of perceived imagery and cohesion are reciprocally related on the basis of theories concerning the relationship between cognition and affect. The implications of these findings suggest that the team cohesion and imagery relationship could be used for team building and a team intervention tool with other cognitive variables.
采用群体环境问卷(Carron et al.， 1985)和运动意象问卷(Hall et al.， 1998)对博茨瓦纳45名优秀团队运动运动员的凝聚力感知和意象使用进行了评估，以确定变量之间是否存在关系，以及意象使用是否会显著预测团队凝聚力。相关分析结果显示，图像使用对衔接的综合影响显著(p . 0.05)，而两个变量的共同方差为6.7%。此外，我们还发现，动机特定意象和认知一般意象的使用是团队成员感知凝聚力的显著预测因子(p< 0.05)。在认知和情感关系理论的基础上，研究结果进一步表明，感知意象和衔接的认知和情感因素是相互关联的。研究结果表明，团队凝聚力和意象关系可用于团队建设，并可与其他认知变量一起作为团队干预工具。

The labour market in South Africa (SA) has been characterized by very high and increasing rates of unemployment and an acute shortage of skilled workers. Consequently, finding competent people who will fit in with an organisation’s culture, vision and strategic goals has been challenging. As a result, the recruitment drives of many organisations currently focus heavily on attracting skills as well as experience. One of the ways in which the skills shortage and lack of experience could be addressed would be by including an internship in the curricula of different programmes offered at Higher Education Institutions. The current study seeks to articulate from a student’s perspective the value of internship in the professional preparation of sport management personnel and attempts to contribute to research in education by providing empirical evidence on the usefulness of internships and make recommendations thereon. A 47-item questionnaire was administered to 300 interns at three universities which offered sport management programmes with internship as a compulsory component. Analyses were performed using the Statistical Package for Social Sciences (SPSS – version 17). Principal component analysis (PCA) was conducted on the data. A final model consisting of seven factors which accounted for 77.80% of the overall variance in the scale item scores was produced. The factors were professional development (five items), personal development (five items), marketability (thee items), adaptability (thee items), relevance (thee items), opportunity for growth (two items) and networking (two items). The study found internships to be a valuable component in the sport management curriculum. Emanating from the findings several recommendations were made. Key words: Internship; Labour; Professional development; Personal development; Marketability; Relevance.
南非劳动力市场的特点是失业率非常高，而且还在不断上升，熟练工人严重短缺。因此，找到能够适应企业文化、愿景和战略目标的人才一直是一项挑战。因此，许多组织目前的招聘动机主要集中在吸引技能和经验上。解决技能短缺和经验缺乏的方法之一是在高等教育机构提供的不同课程的课程中加入实习。本研究试图从学生的角度阐述实习在体育管理人员专业准备中的价值，并试图通过提供实习有用性的经验证据，为教育研究做出贡献，并就此提出建议。向三所大学的300名实习生发放了一份包含47个项目的问卷，这三所大学提供体育管理课程，实习是必修课。使用社会科学统计软件包(SPSS - version 17)进行分析。对数据进行主成分分析(PCA)。最终模型由七个因素组成，占量表项目得分总方差的77.80%。这些因素包括专业发展(5个项目)、个人发展(5个项目)、适销性(3个项目)、适应性(3个项目)、相关性(3个项目)、成长机会(2个项目)和人脉(2个项目)。研究发现，实习是体育管理课程的重要组成部分。根据调查结果提出了几项建议。关键词:实习;劳动力;专业发展;个人发展;市场化;的相关性。

The objective of this study was to investigate the interaction between the prior experience, cognitive perceptions and psychological skills of senior rugby players in South Africa. The study population included 139 trans-national players, 106 provincial players and 95 club rugby players (N=340). A cross-sectional design was used to assess the players’ psychological skills by means of the Athletic Coping Skills Inventory-28 (ACSI-28). Players’ prior experience and cognitive perceptions were determined by means of a biographical questionnaire. Different biographical variables appeared to distinguish between the groups with respectively high and low levels of psychological skills on the different levels of rugby. The players’ perceptions regarding their own abilities to optimally prepare themselves psychologically before a game appeared to be the only common denominator differentiating between the groups with high and low levels of psychological skills. A combination of perceptions and prior experience explained 44.81% of t he variance in the psychological skills (ACSI-28 total) of the club rugby players, 9% of the variance on provincial level and 21.3% of the variance on trans-national level. There appeared to be significant interaction between prior sport experience, certain cognitive perceptions and the psychological skills of the rugby players involved in this study. Cognitive psychological intervention could therefore play an important part in the psychological preparation of senior rugby players in South Africa. Key words: Psychological skills; Cognitive perceptions; Prior experience; Rugby.

The objective of the study was to analyse age group differences among and unique to 10 to 15 year old boys of different racial groups living in the North West Province (NWP) of South Africa. Boys (N=604) between 10 and 15 years participated in the study. They were a randomized group and a proportional representation of the four different racial groups living in the NWP. The tests included the Australian Talent Search protocol, consisting of 10 parameters (four anthropometrical, one physical and five motor abilities) and four additional physical fitness parameters (abdominal, grip- and upper body strength and flexibility). The analyses were based on cross sectional data and age group comparisons for anthropometric composition, physical and motor abilities of the boys. Analysis of Variance with an age and group effect revealed growth patterns similar to other studies, although unique growth characteristics were also found in the different racial groups, suggesting population variation. Age group differences and tendencies with regard to body dimensions and physical and motor abilities were indicated. In order to achieve a distinct profile of the current and future sporting potential of a boy in his rapid growing years, it is recommended that comparison to peers from a sport talent perspective will provide a more sensitive assessment when regional or national reference data, but also racial specific growth profiles, are used. The results of this study can serve as areference base for future comparisons in order to ensure that the most talented children are identified for sport on the basis of their own growth profile.

Literature indicates that deficiencies of certain parameters such as biomechanics, anthropometry, physical and motor abilities, may influence a netball players susceptibility to injury, as well as the players physical performance during a game. The primary aim of this study was to determine the physical profile of elite netball players from the North-West University club, between 18 and 25 years old, with reference to the biomechanical, anthropometrical, physical and motor abilities (balance, agility and explosive power). The secondary aim was to identify shortcomings in the physical profile of netball payers that could contribute to musculoskeletal injuries among players. The results reveal numerous biomechanical deviations among the netball payers during the first and second testing procedures. With regard to anthropometry, the group presented an ideal body mass index, but with an above-average fat percentage. A comparison of the incidences of injury among the players indicated that players with more biomechanical stressors showed more injuries during the season. Key Words: Elite Netball Players; Biomechanical; Anthropometric; Physical; Profile; Musculoskeletal Injuries.

The aim of this study was to determine the effect of growth and maturation over a period of three years on the physical and motor abilities and rugby skills of talented young rugby players aged 15 to 18 years. Differences between early developers (ED) (n = 4), average developers (AD) (n = 13) and late developers (LD) (n = 1) were also assessed over the three-year period. Flexibility, leg and back strength, muscle endurance, speed and aerobic endurance were measured using different standardized tests. Differences over the three-year period were analysed within and between groups using descriptive statistics, repeated measurements over time and two-way Analysis of Variance. An analysis adjusting for race and playing position was also performed to evaluate the role of these characteristics in the results. Results indicated no significant differences in physical and motor abilities or rugby skills of players between ages 15 and 18 years, although significant improvement was seen in flexibility and explosive strength of early and average developers. Furthermore race showed an effect on strength measurements (especially leg strength), and player position on leg strength and aerobic endurance, while the effect of late development seems to shrink as boys grow older.
