Daniel Anderson, James Nunn, Christopher J Tyler
The purpose was to compare 14°C (CWI14°C) and 5°C (CWI5°C) cold water immersion following intermittent running. On three occasions, nine male team-sport players undertook 12 min of CWI14°C, CWI5°C or non-immersed seated recovery (CON) following 45 min of intermittent running exercise. Maximal cycling performance and markers of recovery were measured before and in the 0 - 72 h after exercise. Peak power output (PPO) was immediately reduced following all interventions (d = 1.8). CWI5°C was more effective at restoring PPO than CWI14°C (d = 0...

BACKGROUND: The health outcomes of men continue to be poorer than women globally. Challenges in addressing this problem include difficulties engaging men in weight loss programs as they tend to view these programs as contrary to the masculine narrative of independence and self-reliance. Researchers have been turning towards sports fans to engage men in health promotion programs as sports fans are typically male, and tend to have poor health habits. METHODS: Developed from the highly successful gender-sensitized Football Fans in Training program, Hockey Fans in Training (Hockey FIT) recruited 80 male hockey fans of the London Knights and Sarnia Sting who were overweight or obese into a weekly, 90-minute classroom education and group exercise program held over 12 weeks; a 40-week minimally-supported phase followed...

The perception that children and adolescents have of injuries may be influenced by their depiction in sport-related films. The objective of this study was to determine the depiction of injuries in a select number of sport-related films. Forty-four films were analyzed. Injury category, on-the-field management, and long-term management were determined for each injury. Major injuries were defined as injuries requiring prompt intervention and immediate discontinuation of sport participation. A total of 49 injuries were depicted, categorized as fracture (n = 11), contusion (n = 10), brain concussion (n = 8), muscle cramps (n = 5), laceration/abrasion (n = 4), ligamentous knee injury (n = 4), shoulder dislocation (n = 2), rotator cuff injury (n = 2), ankle sprain (n = 2), and unspecified injury (n = 1)...

Background: The term "swimmer's shoulder" was first introduced in 1974 by Kennedy and Hawkins to describe a common condition among competitive swimmers characterized by pain and dysfunction of the shoulder complex. Currently, the term does not define a specific clinical diagnosis and its etiology is considered to be multifactorial. In the literature shoulder pain prevalence varies according to the adopted definitions (from 3% to 91%); however, in the Italian environment there is no prevalence study regarding swimmer shoulder...

We tested Petrie and Greenleaf's psychosocial model in relation to male athletes' bulimic symptomatology. Through structural equation modeling, we cross-sectionally examined the direct and indirect effects of general and sport-specific appearance pressures, internalization, body satisfaction, drive for muscularity, negative affect, and dietary restraint on bulimic symptomatology. Participants were U.S. male collegiate athletes (N = 698; Mage = 19.87 years) representing 17 sports. With minor respecifications, the model had acceptable fit, and the psychosocial variables explained 48% of the bulimic symptomatology variance...

REVIEW
Anthony J Shield, Matthew N Bourne
Hamstring strain injuries are endemic in running-based sports. Given the economic and performance implications of these injuries, a significant body of research has emerged in recent years in an attempt to identify risk factors and develop or optimise injury prevention strategies. Surveys of injury prevention practices among medical and conditioning staff in elite sport suggest that many sporting clubs invest significant efforts in eccentric hamstring conditioning and lumbo-pelvic or trunk stability programmes...
