Three-dimensional kinematics of the lower limbs during forward ice hockey skating

The objectives of the study were to describe lower limb kinematics in three dimensions during the forward skating stride in hockey players and to contrast skating techniques between low- and high-calibre skaters. Participant motions were recorded with four synchronized digital video cameras while wearing reflective marker triads on the thighs, shanks, and skates. Participants skated on a specialized treadmill with a polyethylene slat bed at a self-selected speed for 1 min. Each participant completed three 1-min skating trials separated by 5 min of rest. Joint and limb segment angles were calculated within the local (anatomical) and global reference planes. Similar gross movement patterns and stride rates were observed; however, high-calibre participants showed a greater range and rate of joint motion in both the sagittal and frontal planes, contributing to greater stride length for high-calibre players. Furthermore, consequent postural differences led to greater lateral excursion during the power stroke in high-calibre skaters. In conclusion, specific kinematic differences in both joint and limb segment angle movement patterns were observed between low- and high-calibre skaters.     

Mood responses to athletic performance in extreme environments

Competition at elite level can require athletes to perform optimally in extreme environmental conditions. This review focuses on mood responses in such conditions and proposes practical guidelines for those working with athletes. Different environments are considered, including altitude and extreme heat and cold. Performing in extreme heat, cold or at altitude can produce a stress response characterized by increased negative mood and relatively poor performance. Positive adaptations to extreme conditions can be accelerated, but the rate of adaptation appears to be highly individualized. Monitoring mood responses to training under normal conditions provides a basis for identifying the psychological effects of extreme conditions. It is suggested that practitioners carefully monitor the interplay between vigour, fatigue and depressed mood. Reductions in vigour and increases in fatigue are normal responses to hard training, but other aspects of mood disturbance, especially symptoms of depressed mood - however small - may be indicative of a maladaptive response, and practitioners should consider intervening when such symptoms first appear.

The Impact of Modularity and Credit Accumulation on Undergraduate Art and Design Education

Credit Accumulation and modular structures now account for the majority of undergraduate provision in art and design in the UK. This shift away from traditional structures has gained momentum during the past three years and is part of a national move towards credit accumulation and modularity from GCSE through to Masters level work in all subjects. The origins and rationale for these structures are outlined and their advantages are discussed with particular reference to art and design in Higher Education, together with their implications for teaching methods, for student learning, and for assessment. These points are illustrated with examples of new developments in the sector. The author responds to some of the reservations voiced by critics of CATS and Modularity and argues that these structures are more appropriate to the needs and ambitions of students in the 1990s.
