A recently developed social psychological and biographical approach to the study of lives, life positioning analysis (LPA), is applied to the early life experiences of Canadian basketball player Steve Nash for the purpose of identifying sources of his athletic creativity and work ethic. The analysis focuses on Nash’s childhood and adolescence, especially his interactions with his father, brother, coaches, friends, and teammates. The interpretations, results, and conclusions offered describe specific types of interaction with these other individuals as likely influences on the development of important psychological aspects of the team oriented creativity that came to characterize Nash’s unique athletic style. The article concludes with a brief description of the unique yields and possible contributions of this type of biographical case study as a methodological approach in sport psychology.

Twenty spinal-cord-injured subjects (4 quadriplegics and 16 paraplegics) were maximally stress tested on the Arizona State University wheelchair ergometer. Physiological data for each individual were collected as follows: (a) blood flow in the left leg by a photoelectric plethysmograph before exercise, during exercise, and postexercise, and (b) blood lactates before exercise and post-exercise. Eleven subjects had increased leg blood flow and vasodilation during exercise, but vasoconstriction postexercise. The lactate readings, in comparison to able-bodied individuals, were higher at rest but lower at maximal exercise.

The purpose of this study was to assess the difference in maximal physiological responses between an acute bout of deep-water running (DWR) and treadmill running (TMR) in young and older adults. Participants were 9 young and 9 older women who performed maximal DWR and TMR tests. Maximal measures included oxygen consumption (VO2max), heart rate (HRmax), ventilation (VE), respiratory-exchange ratio (RER), and blood lactate (BLac). The young women exhibited higher VO2max, HRmax, VE, and BLac than did the older women for both exercise conditions (p < .05). Lower VO2max and HRmax values were observed with DWR for both age groups (p < .05). No significant differences were found for VE, RER, and BLac in either group between exercise conditions, nor a significant interaction between exercise conditions or ages for any of the variables measured. The data suggest that although older adults exhibit lower maximal metabolic responses, differences between DWR and TMR responses occur irrespective of age.

Recent research has suggested that the Social Physique Anxiety Scale (SPAS) is a multidimensional rather than a unidimensional measure. The present study challenged this position on both conceptual and empirical grounds. After deleting three questionable items from the SPAS, a series of confirmatory factor analyses were conducted across four samples of women who had completed the scale. Across all samples, the model fit indices (i.e., all > .90) suggested that a nine-item, single factor model of the SPAS is more parsimonious and conceptually clear than a two-factor model. It is recommended that researchers of social physique anxiety begin to use the nine-item version of the SPAS described in this paper.
