Physical activity parenting measurement and research : challenges, explanations and solutions

Physical activity (PA) parenting research has proliferated over the past decade, with findings verifying the influential role that parents play in children's emerging PA behaviors. This knowledge, however, has not translated into effective family-based PA interventions. During a preconference workshop to the 2012 International Society for Behavioral Nutrition and Physical Activity annual meeting, a PA parenting workgroup met to: (1) Discuss challenges in PA parenting research that may limit its translation, (2) identify explanations or reasons for such challenges, and (3) recommend strategies for future research. Challenges discussed by the workgroup included a proliferation of disconnected and inconsistently measured constructs, a limited understanding of the dimensions of PA parenting, and a narrow conceptualization of hypothesized moderators of the relationship between PA parenting and child PA. Potential reasons for such challenges emphasized by the group included a disinclination to employ theory when developing measures and examining predictors and outcomes of PA parenting as well as a lack of agreed-upon measurement standards. Suggested solutions focused on the need to link PA parenting research with general parenting research, define and adopt rigorous standards of measurement, and identify new methods to assess PA parenting. As an initial step toward implementing these recommendations, the workgroup developed a conceptual model that: (1) Integrates parenting dimensions from the general parenting literature into the conceptualization of PA parenting, (2) draws on behavioral and developmental theory, and (3) emphasizes areas which have been neglected to date including precursors to PA parenting and effect modifiers.

Louise Lightfoot : in search of India

 Louise Lightfoot, a trained architect by profession and an ardent balletomane, is best known for moving away from pure Western classical Ballet to a fusion of classical technique and romantic emotion in Australia through her First Australian Ballet group and school. During late 1920s, she was impressed by the performances of Anna Pavlova and Uday Shankar and to bring more appropriateness and authenticity to her own Indian classical dance style that she was trying to experiment with, virtually unknown and unseen in Australia till then in its original form, Lightfoot took a few weeks stopover in India. This short holiday eventually stretched to months and then eight years as she travelled to Tamil Nadu and Kerala’s Kalamandalam, where she began her study of the complex traditions of Kathakali and Bharata Natyam dance. Here she also became a Stage Manager cum Artistic and Publicity director for local troupes and artistes in residence. She was so thrilled by the whole experience of learning Kathakali – involving poetry, song, acting and dance – that soon she started appealing to the British in India to not only appreciate the Indian dance but also to Indian parents to allow their sons and daughters to dance. Lightfoot, as Dance Director of Shivaram, Janaki Devi, Priyagopal Singh and Lakshman Singh, supported by an ensemble of Australian dancers including Ruth Bergner, Moya Beaver, Leona Welch, Pat Martin and Betty Russell, successfully toured and promoted a range of Indian classical dance forms, like Kathakali, Manipuri, Bharatanatyam, throughout Australia, New Zealand, and Fiji. As an early image-maker, she also paved the way for many other noted Indian dancers and troupes. In spite of decades of hard work and dedication to Indian dancing and creating awareness about India in Australia her work and life is little known! Her journey is fascinating because of the workings of race relations not just in Australia but also India – existing prejudices against “Whites.” In this paper I try to chart out through Australian and Indian newspaper reports her search for India.

Interview with Louise "Lou" Trucks

In her December 2014 interview with Michelle Dubert-Bellrichard, Louise “Lou” Trucks detailed her thoughts and memories of her time at Winthrop. Trucks spoke of the time period from 1960-1964 as a music and music education double major. Trucks shared the benefits of being a music major, her involvement in campus traditions and organizations, and the rigor of her studies. Trucks concludes her interview detailing her life after Winthrop in Bloomington, IN and Rochester, NY. This interview was conducted for inclusion into the Louise Pettus Archives and Special Collections Oral History Program.

Music tempo's effect on exercise performance: comment on dyer and mckune

Dyer and McKune (2013) stated that music tempo has no influence on performance, physiological, and psychophysical variables in well-trained cyclists during high intensity endurance tasks. However, there are important limitations in the methodology of the study. The participants'music preferences and tempo change were not well measured. It is not possible to affirm that music tempo does not influence athletes'performance. Potential areas of future research include: (a) use of instruments to assess the qualities of music; (b) standardizing music of tempo according to exercise type (e.g., running, cycling, etc.); (c) considering training level of the participants (i.e., athletes and non-athletes); and (d) use of instruments to assess concentration during exercise.

Glomerular filtration rate estimates decrease during high altitude expedition but increase with Lake Louise acute mountain sickness scores

AIM: Acute mountain sickness (AMS) can result in pulmonary and cerebral oedema with overperfusion of microvascular beds, elevated hydrostatic capillary pressure, capillary leakage and consequent oedema as pathogenetic mechanisms. Data on changes in glomerular filtration rate (GFR) at altitudes above 5000 m are very limited. METHODS: Thirty-four healthy mountaineers, who were randomized to two acclimatization protocols, undertook an expedition on Muztagh Ata Mountain (7549 m) in China. Tests were performed at five altitudes: Zurich pre-expedition (PE, 450 m), base camp (BC, 4497 m), Camp 1 (C1, 5533 m), Camp 2 (C2, 6265 m) and Camp 3 (C3, 6865 m). Cystatin C- and creatinine-based (Mayo Clinic quadratic equation) GFR estimates (eGFR) were assessed together with Lake Louise AMS score and other tests. RESULTS: eGFR significantly decreased from PE to BC (P < 0.01). However, when analysing at changes between BC and C3, only cystatin C-based estimates indicated a significant decrease in GFR (P = 0.02). There was a linear decrease in eGFR from PE to C3, with a decrease of approx. 3.1 mL min(-1) 1.73 m(-2) per 1000 m increase in altitude. No differences between eGFR of the two groups with different acclimatization protocols could be observed. There was a significant association between eGFR and haematocrit (P = 0.01), whereas no significant association between eGFR and aldosterone, renin and brain natriuretic peptide could be observed. Finally, higher AMS scores were significantly associated with higher eGFR (P = 0.01). CONCLUSIONS: Renal function declines when ascending from low to high altitude. Cystatin C-based eGFR decreases during ascent in high altitude expedition but increases with AMS scores. For individuals with eGFR <40 mL min(-1) 1.73 m(-2), caution may be necessary when planning trips to high altitude above 4500 m above sea level.
