Cardiovascular and ventilatory responses during formalized T'ai Chi Chuan exercise

T'ai Chi Chuan (TCC) is a widely practiced Chinese martial art said to physically develop balance and coordination as well as enhance emotional and mental health. TCC consists of a series of postures combined into a sequential movement providing a smooth, continuous, low-intensity activity. The purpose of this study was to examine the ventilatory and cardiovascular responses to the Long Form of Yang's style TCC. In addition, the subjects' TCC responses were compared to their ventilatory and cardiovascular responses during cycle ergometry at an oxygen consumption (VO2) equivalent to the mean TCC VO2. Six experienced (M = 8.3 yrs) male TCC practitioners served as subjects with data collected during the Cloud H and movement of the TCC exercise. Significantly (p less than .05) lower responses for ventilatory frequency (Vf) (11.3 and 15.7 breaths.min-1), ventilatory equivalent (VE/VO2) (23.47 and 27.41), and the ratio of dead space ventilation to tidal volume (VD/VT) (20 and 27%) were found in TCC in comparison to cycle ergometry. The percentage of minute ventilation used for alveolar ventilation was significantly higher during TCC (p less than .03) than cycle ergometry, with mean values of 81.1% and 73.1%, respectively. Cardiac output, stroke volume, and heart rate were not significantly different between TCC exercise and cycle ergometry at the same oxygen consumption. We concluded that, during TCC, expert practitioners show significantly different ventilatory responses leading to more efficient use of the ventilatory volume than would be expected from comparable levels of exertion on a cycle ergometer.     

‘If you miss the ball,you look like a total muppet!’ Boys investing in their bodies in physical education and sport

Connections have been drawn between masculinity, muscularity and physical or social status in sport. Not only are sporting bodies often related to masculinity but also to whiteness, leading to the devaluing of Asian boys' bodies and sporting experiences. This paper draws on three British Asian teenage boys' visual and verbal narratives to enquire how they negotiate these connections in their physical education and recreational sport experiences. Bourdieu's notion of capital is used to make sense of boys' ways of investing in their bodies to manage their status in school. Drawing from focus-group interviews which used participant-driven photography and photo elicitation techniques, the research indicates how three boys invested in their bodies by doing particular types of physical activity that would enable them to develop muscularity, fitness and/or motor competence, to attain or retain physical and social capital in school. Along the way, they add pertinent comments on the intersections of masculinity and ethnicity in constructing and performing a sporting body.     

Yer Doin’ it Wrong: How NOT to Interact with Vendors,Publishers, or Librarians

Three librarians who have extensive experience working in libraries or for publishers, vendors, or consortia presented an informal discussion on librarian–vendor relationships. The audience was encouraged to participate. Problems were articulated; speakers and audience members contributed suggestions for better approaches or behaviors when handling difficult situations.     

#MeToo,sexual harassment: an article,a forum,and a dream for the future

#MeToo has breathed new life into the women’s movement and especially into understanding and rectifying sexual harassment, abuse and assault. It has galvanized activists around the globe. And it has placed thousands of stories of the harassed in full view of the public. Sexual harassment, abuse and assault may occur within the organizational context or beyond; but sexual harassment, in particular has been legally labeled an organizational phenomenon. With this in mind, Robin Clair frames the early part of this article around the most recent organizational communication theories (see the appendix for an overview of these theories). Following the essay is a forum, in which invited scholars address questions related to the #MeToo movement.     

Girls’ active identities: navigating othering discourses of femininity,bodies and physical education

Within physical education and sport, girls must navigate discourses of valued athletic and gendered bodies that marginalise or ‘other’ non-normative performances through systems of surveillance and punishment. The purpose of this paper is to share girls’ perspectives on how these discourses affected their gender performances and activity engagement. Students aged 13–14 in one ethnically diverse UK secondary school were invited to create a photo diary of the physical activities they engaged in. Photo-elicitation interviews in small groups followed. The girls positioned themselves as physically active but had to carefully manage their activity choices and gender performances in a single-sex physical education environment that regulated deviation from the fit, slender, girly-girl. Although the girls demonstrate the difficulty of resisting, they indicate moments of positioning themselves against norms that suggest the possibilities of shifting gendering processes. The paper points out the importance of listening to ‘other’ girls’ narratives in building positive physical education engagements.
