Doping cases have in the recent past (second decade of 21st century) tainted the Kenyan athletes' dominance in long distance running. The purpose of this study was to examine the knowledge, attitudes and perceptions (KAP) on doping among university students pursuing sport related courses. It was postulated that KAP on doping will be mediated by year of study, age, gender, sporting experience and degree programme. Data were collected through self-administered questionnaires from university students (n=179) drawn from four universities that offer sport-related courses in Kenya. Results revealed that there were significant differences between year of study (first vs fourth) in knowledge on performance enhancing substance (PES) (Mean Ranks; 68.16 vs 94.22, p=.013) and perceptions about doping (109.98 vs 86.14, p=.023). Sport Science and Health Promotion students showed significantly higher scores on attitudes towards doping (p=.003) than those in Physical Education courses. There were significant differences (p < .05) in KAP on doping in favour of those students who had previous participation in sport competitions. It is concluded that KAP of university students on doping is differentiated based on the selected variables of year and programme of study, and previous participation in sport competitions. It is recommended that the unpacking of doping education should take these variables into consideration. Universities need to partner with anti-doping agencies to expose students to both theoretical and practical applications of doping knowledge. Further investigation in needed on the possible factors that contribute to less negative perceptions with higher knowledge on doping among university students.

.3 yr) were instrumented with a radial artery catheter, an esophageal balloon-tipped catheter, and an esophageal temperature probe for the determination of blood gases, the work of breathing and core temperature, respectively. Testing occurred at 1545 m above sea level. Results There were significant decreases in the arterial partial pressure of O2 and oxyhemoglobin saturation and a widening of the alveolar-to-arterial difference in O2 from rest to peak exercise. The mechanical work of breathing increased with increasing minute ventilation and was commensurate with values expected for treadmill running in elite athletes. During heavy exercise, significant expiratory flow limitation was present in half of the subjects while the remaining subjects demonstrated impending flow limitation. Conclusions Pulmonary system limitations were present in Kenyan runners in the form of exercise-induced arterial hypoxemia, expiratory flow limitation, and high levels of respiratory muscle work. It appears that Kenyan runners do not posses a pulmonary system that confers a physiological advantage....

Mental toughness is a psychological construct related to successful performance in academics, management, and sports among other sectors. However, studies on the determinants of mental toughness with respect to different human endeavours have remained inconclusive. This study explored mental toughness characteristics of male university athletes in selected sports in relation to contextual factors of athletes’ age, playing experience, year of study, and the type of sport. The Mental Toughness Questionnaire (MTQ48) was used to collect data from male university athletes (n = 140). Results of this study showed significant difference in the following components of MT: lower scores in challenge (p = .015), emotional control (p = .005), and life control (p = .002) among athletes with shorter playing experience, and higher scores in life control (p < .001), emotional control (p = .021), and confidence in abilities (p = .009) in handball as compared to soccer players. Soccer players had significantly higher scores in the challenge component (p = .038) of mental toughness as compared to handball players. It was concluded that playing experience and the type of sport influenced characteristics of mental toughness among university athletes. Coaches, trainers, and sports psychologists need to consider these contextual factors to optimize mental toughness of athletes. Future studies should explore how specific contextual factors influence training environments and outcomes, as well as how stakeholders can leverage on the relationships between playing experience, the type of sport and mental toughness to augment athletes’ mental toughness and sports performance.

Health benefits of physical activity are well known, yet available physical activity data is limited from children living in African and Asian countries. The purpose of the cross-sectional study was to evaluate and compare physical activity and sedentary behavior patterns, particularly hourly variations, among children in Kenya and Japan. Participants included 298 primary school students (122 Kenyan, 176 Japanese) aged 9–12 years. Physical activity and sedentary behavior were measured with accelerometers. Domain-specific physical activity, screen time, and proportion of children using active transport to school were measured by questionnaire. A two-way ANOVA (countries × time) was used to examine the differences in the activity patterns between Kenyan and Japanese children. The results from the present study demonstrated that Kenyan children spent more time in moderate-to-vigorous physical activity compared to Japanese children (p < 0.05) with the greatest differences found for weekday evenings (for boys and girls) and weekend afternoons (for girls). This suggests that these were ‘critical periods’ to differentiate the physical activity levels between Kenyan and Japanese children. However, a higher proportion of the children from Japan used active transport to school and spent less time in television viewing and computer gaming. The results suggest that both countries have successes and challenges that can aid in developing effective and country-specific intervention strategies for promoting physical activity.

Children’s physical activity (CPA) in low- and middle-income regions has received increasing attention, but research is still very limited. This study explores the CPA in contemporary pastoralist Maasai society in rural Kenya by considering its sociocultural dimensions. The physical activity of 25 children (15 girls and 10 boys) was documented with mixed methods, including an epidemiological assessment of the CPA and semi-structured interviews with the targeted children regarding their daily activities. These methods were integrated with the ethnographic data on children’s socialization in the same area. Results showed a very high level of moderate-to-vigorous physical activity (MVPA) of these children with significant gender differences especially outside school. Children reported their continued social participation in local gender–age labor divisions outside of school. As their activities outside school strongly contributed to their empirical learning of local knowledge and skills, a high MVPA plays an active role in enhancing the children’s ability to access and manage livestock and different natural resources. Findings from this study first show that the CPA is not merely physical, but also has significant sociocultural meanings in the process of in situ learning of local wisdom. We call more attention to children’s social roles in future investigations of CPA among less examined populations.
