Today's elite hockey players are physically bigger and have improved levels of physiological fitness when compared with their predecessors. Correspondingly, previous ice hockey studies that have become widely referenced may have little relevance to current players and the way the game is presently played. A great need exists to apply ...

A mail survey of degree of seasonal suffering was conducted in Italy using the SPAQ (Seasonal Pattern Assessment Questionnaire). Experiencing seasonal changes as a problem was reported by more than half of the 543 responders. Both mean GSS (Global Seasonality Score) and circannual profile of 'feeling worst' yielded results similar ...

As a consequence of performing plyometric type exercises, such as depth jumps, impact forces placed on the musculoskeletal system during landing can lead to a potential for injury. A reduction of impact forces upon landing could therefore contribute to reduce the risk of injury. Twenty subjects performed a series of ...

A case of pyomyositis in a healthy 13-year-old female volleyball player is presented and discussed. This case is unusual because, historically, pyomyositis has been more common in males, especially those who participate in strenuous physical activity. However, competitive sports and vigorous exercise programs are becoming more widely available to young ...

Athletes are susceptible to upper respiratory tract infection (URTI) during intense training and after major competition; high rates of URTI have also been associated with the overtraining syndrome (staleness). Secretory immunoglobulin A (IgA), the predominant immunoglobulin in mucosal secretion, is a major effector of resistance against pathogenic microorganisms causing URTI. ...

Plyometric activities, engaging the muscle in a stretch-shortening cycle, are widely used in athletic training. One such plyometric exercise is drop-jumping, where the athlete drops from a raised platform and immediately on landing performs a maximal vertical jump. These actions are also performed with the athlete externally loaded by the ...
