Psychosocial correlates of cardiorespiratory fitness and muscle strength in overweight and obese post-menopausal women: a MONET study

The purpose of this study was to examine the psychosocial correlates of cardiorespiratory fitness (VO2peak) and muscle strength in overweight and obese sedentary post-menopausal women. The study population consisted of 137 non-diabetic, sedentary overweight and obese post-menopausal women (mean age 57.7 years, s = 4.8; body mass index 32.4 kg.m(-2), s = 4.6). At baseline we measured: (1) body composition using dual-energy X-ray absorptiometry; (2) visceral fat using computed tomography; (3) insulin sensitivity using the hyperinsulinaemic-euglycaemic clamp; (4) cardiorespiratory fitness; (5) muscle strength using the leg press exercise; and (6) psychosocial profile (quality of life, perceived stress, self-esteem, body-esteem, and perceived risk for developing chronic diseases) using validated questionnaires. Both VO2peak and muscle strength were significantly correlated with quality of life (r = 0.29, P < 0.01 and r = 0.30, P < 0.01, respectively), and quality of life subscales for: physical functioning (r = 0.28, P < 0.01 and r = 0.22, P < 0.05, respectively), pain (r = 0.18, P < 0.05 and r = 0.23, P < 0.05, respectively), role functioning (r = 0.20, P < 0.05 and r = 0.24, P < 0.05, respectively), and perceived risks (r = -0.24, P < 0.01 and r = -0.30, P < 0.01, respectively). In addition, VO2peak was significantly associated with positive health perceptions, greater body esteem, and less time watching television/video. Stepwise regression analysis showed that quality of life for health perceptions and for role functioning were independent predictors of VO2peak and muscle strength, respectively. In conclusion, higher VO2peak and muscle strength are associated with a favourable psychosocial profile, and the psychosocial correlates of VO2peak were different from those of muscle strength. Furthermore, psychosocial factors could be predictors of VO2peak and muscle strength in our cohort of overweight and obese sedentary post-menopausal women.     

Exploring coaching actions based on developed values: a case study of a female hockey coach

There are few empirical studies that demonstrate how values are developed and how they are linked to coaching actions. There can be a discrepancy between the statement of coaches’ values and their actual coaching actions. In order to examine how coaching actions are influenced by values that are developed over a lifetime, the purpose of this article is to first describe a female hockey coach’s approach to coaching using five key coaching actions, then identify the underlying values that influenced those actions, and then explore how these values were developed in different experiences throughout her life. A time-oriented network analysis was conducted based on four semi-structured, in-depth interviews with the coach. The results present five key coaching actions: (a) organizing coach education programmes for athletes, (b) creating groups to help athletes bond, (c) bringing in experts from various domains, (d) asking athletes to reflect on attitudes and goals, and (e) giving athletes playing time based on hard work and effort. We identify the core values guiding these actions as: (a) equity, (b) connectedness, (c) holistic development, (d) respect, and (e) effort. Finally, we present a number of the coach’s experiences that demonstrate the complexity of developing these values throughout her life. The importance of reflecting on and discussing coaching actions, experiences, and the underlying learned values may help coaches develop coaching actions that are guided more explicitly by those values.     

如何成为思考型教练员

为扮演好各种角色,不同级别的教练员都必须掌握和使用越来越复杂的专业化知识。因此,世界上许多国家都提供大型的综合项目,来帮助教练员实现这一目标,教练员教育得到迅猛发展,教练员教育国际委员会应运而生。然而,在教练员看来,与正式的教育相比,他们在训练指导实践中所获得的知识更有利于其职业发展。研究显示,美国高校的教练员用于教练员培训机构的平均时间为每年25h,     

Analysis of coaching science research published from 1970-2001

The study followed a four-phase design. In Phase I an exhaustive search was conducted for all English language coaching research published in journals from 1970 to 2001. In Phase II, copies of the research were obtained. An expert panel conducted a manual search and a review in Phase III to address validity. Analysis of the research was completed in Phase IV (Culver Gilbert, & Trudel, 2003; Silverman & Skonie, 1997). Over 1,100 articles were reviewed, and 610 met the inclusion criteria. Selected findings include: (a) a relatively low mean spread across many journals, (b) a focus on coaching behavior using quantitative methodologies, and (c) a primary emphasis on team sports in school contexts.
