Ankle sprain injuries in amateur soccer players are primarily contact injuries, occurring mainly in defenders and during both games and practice. It appears that more injuries occur in players with previous ankle injury. Injury rates are higher toward the end of a game and chiefly occur during the first 2 months of the season.

Relatively little research drawing from self-determination theory has examined the links between controlling teaching environments and student motivation. To this end, two longitudinal studies were conducted to explore how students’ perceptions of controlling teaching behavior and experiences of psychological need frustration were associated with a number of motivation-related outcomes over a school year. Multilevel growth modelling indicated that changes in perceptions of controlling teaching positively related to changes in need frustration across the school year (Studies 1 & 2) which, in turn, negatively related to autonomous motivation and positively related to controlled motivation and amotivation in Study 1 (N = 419); and positively related to fear of failure, contingent self-worth, and challenge avoidance in Study 2 (N = 447). Significant indirect effects also supported the mediating role of need frustration. These findings reinforce the need for research on the negative motivational pathways which link controlling teaching to poor quality student motivation. Implications for teacher training are discussed

The present study examined the link between motivation profiles among adult sports participants and the consequences of enjoyment, effort, positive and negative affect, attitude toward sport participation, intention to continue sport participation, satisfaction, and frequency of attendance in sport. Two samples of participants (n = 590 and n = 555) completed the Sport Motivation Scale and a range of self-report measures to assess the outcome variables. Exploratory cluster analyses applied to Sample 1 and confirmatory cluster analysis applied to Sample 2 identified two clusters of sport participants. The first comprised participants with high scores on both nonself-determined and self-determined motives. The second comprised participants with high scores on self-determined motives but low scores on nonself-determined motives. Participants in the first cluster scored higher on all outcome variables. The results are discussed with reference to a more in-depth understanding of the motivation dynamics of sport participation based on Self-Determination Theory.
