Abstract:

The World Health Organisation called for research assessing the safety of electronic cigarette (e-cigarette). We evaluated the acute effect of active and passive e-cigarette and tobacco cigarette smoking on complete blood count (CBC) markers in 15 smokers and 15 never-smokers, respectively. Smokers underwent a control session, an active tobacco cigarette smoking session, and an active e-cigarette smoking session. Never-smokers underwent a control session, a passive tobacco cigarette smoking session, and a passive e-cigarette smoking session. The results demonstrated that CBC indices remained unchanged during the control session and the active and passive e-cigarette smoking sessions (P > 0.05). Active and passive tobacco cigarette smoking increased white blood cell, lymphocyte, and granulocyte counts for at least one hour in smokers and never smokers (P < 0.05).It is concluded that acute active and passive smoking using the e-cigarettes tested in the current study does not influence CBC indices in smokers and never smokers, respectively. In contrast, acute active and passive tobacco cigarette smoking increase the secondary proteins of acute inflammatory load for at least one hour. More research is needed to evaluate chemical safety issues and other areas of consumer product safety of e-cigarettes, because the nicotine content in the liquids used may vary considerably.

Peer provocation in physical education: experiences of Botswana adolescents

Abstract:

Critical incidents of peer provocation in physical education were investigated among 675 junior secondary school students in Botswana. Data were generated through a brief, open-ended questionnaire requesting the students to narrate their experiences of bad, hurtful and offensive peer behaviours during physical education classes. Six overlapping categories of peer provocation that emerged from the data were: humiliation, injustice, physical assaults, sexual harassment; dangerous play and female physicality frighteners. These categories are discussed with reference to the themes central to boys’ and girls’ experiences. To the extent that peer provocation is differentially aimed at boys and girls, it is crucial to recurrently (en)gender its analysis. This study encourages educators in general and physical education teachers in particular to take heightened interest in, and reflect more critically about proactive ways to address the multiple domains and consequences of peer provocation in physical education settings.

Abstract:

This study examined the relationship between physical self-perception and the involvement of Jamaican youths in sport and physical activity. A sample of 1052 high school students aged between 12 and 19 years completed a Background Information Questionnaire and the Physical Self-Perception Profile. Participants were involved in competitive sport and recreational physical activities, or were non-participants in sport. Results revealed that the 5-factor structure of the PSPP as proposed by Fox and Corbin (1989) was not appropriate for the data obtained. A three-factor model based on the original PSPP items was proposed, consisting of the factors of Physical Self-Worth, Physical Appearance, and Physical Competence. Significant differences between different levels of sport participation on the three factors were found amongst these factors. Practical implications and proposal for further investigation of physical self-concept measures in this culture are made.

Abstract:

This study provides information on the psychological and sociocultural correlates of motor skill development of athletes in Botswana. Seventy-three (73) student athletes were sampled on a psycho-sociocultural and motor skills development questionnaire. Results indicated a positive and moderate relationship of the psychological and sociocultural variables on the athletes' motor skill development. Also, significant gender differences were not (P>.05) apparent in mean rating with the psychological and sociocultural variables as they influenced the athlets' motor skill development.

Position sense and reaction angle after eccentric exercise: the repeated bout effect

Paschalis, V.; Nikolaidis, M.G.; Giakas, G.; Jamurtas, A.J.; Owolabi, E.O.; Koutedakis, Y. (Springer Verlag, http://www.springerlink.com, January 3, 2008)

Abstract:

The purpose of the present investigation was to examine the effects of a repeated eccentric exercise on position sense and muscle reaction angle. Fourteen healthy women underwent an isokinetic exercise session on their knee flexors, which was repeated after 4 weeks. Muscle damage indices, position sense and joint reaction angle of the knee were examined before, immediately after, as well as at 1,2,3,4 and 7 days after exercise. The second exercise bout induced significantly lesser effects in all muscle damage indices as well as lesser disturbances in position sense and reaction angle when compared to the first one. The main finding of this study is that position sense and joint reaction angle to release of the lower limbs may adapt in response to a repeated bout of eccentric exercise, leading to less disturbances in position sense and reaction angle after the second bout of exercise.
