The purpose of this qualitative case study was to explore children with disabilities’ social relationships and motivation to take part in sledge hockey. Harter’s (1978) theory of Competence Motivation was used as the conceptual framework. Ten children (1 girl and 9 boys) between ages 11–16 years, who experienced a range of disabilities, participated. Primary data were collected using semistructured interviews, participant observations, and field and reflective notes. The thematic analysis led to four themes: (a) coach feedback, (b) parental involvement, (c) skill and belonging, and (d) (dis)ability sport. The findings revealed that interactions with significant others contributed extensively to the participant’s perceptions of competence and motivation to participate, as did the sport’s competitive nature. The findings are discussed in the context of Harter’s theory and the children’s sport and adapted physical activity inclusion literature.

The aim of this study was to investigate muscle activity, kinematic, and handgrip-force pattern generation during handcycling. One able-bodied participant performed a 1-min exercise test on a handcycle at 70 revolutions per minute. This article proposes an original data collection and analysis methodology that gathers synchronized kinematics, kinetics, and electromyography. Such data, which most often appear complex, are easily summarized using this methodology. This preliminary study has an new setup and offers good indications on the biomechanical pattern for handcycling movement analysis.

Ten male recreational runners ranging in age from 20 to 32 years were filmed using 3-D cinematography while running on a treadmill at 3.8 m/s, 4.5 m/ s, and 5.4 m/s. The 3-D segment endpoint data were entered into a computer program that computed the segmental contributions to the upward and forward propulsive impulses on the body (lift and drive, respectively) and to the vertical component of angular momentum (Hz). The results of two subjects who demonstrated asymmetrical arm action are discussed in detail and compared with the mean results computed over all subjects. The results revealed that the arms possess the potential to compensate for each other and for asymmetries elsewhere in the body.

A case of tarsal tunnel syndrome in a male collegiate lacrosse player is presented. The subject reported symptoms consistent with tarsal tunnel syndrome following two incidents of medial ankle sprain in one lacrosse season. Conservative treatment was successful following the first ankle sprain but failed to relieve pain and paresthesia in his heel and medial arch following the second injury. Laboratory tests provided an inconclusive diagnosis, and the subject underwent a retinacular release 5 months after the second ankle sprain. Following a 13-week rehabilitation program, the subject returned to full participation in his sport.
