We report the case of a 31 year old female elite athlete. During a routine check-up including a search for hereditary hemostatic risk factors for thrombosis, resistance to activated protein C was detected. Molecular analysis of the factor V gene revealed homozygosity for the factor V Leiden mutation. This is the first documented case of an elite athlete who is a homozygous carrier of factor V Leiden. Elite athletes may be exposed to several circumstantial thrombogenic risk factors and, therefore, special preventive measures in carriers of a congenital risk factor such as APC resistance are indicated. Essential measures are early anticoagulation during periods of immobilisation e.g. after sports-related injuries, a single dose of low-molecular-weight heparin specially for individuals with several thrombotic risk factors and/or leg muscle exercises for long-distance (air) travels and avoiding haemoconcentration with a sufficient oral fluid intake.

The effects of flywheel (FW) training on jump performance, muscle function, and muscle mass in athletes have not been fully clarified. The purpose of the present study was to evaluate the effects of an 8-week FW training program on jump performance, stretch-shortening cycle (SSC) function, muscle strength, peak power and muscle thickness in collegiate basketball players. Twenty male college basketball players (mean age: 19.

Objective: Guardian Caps (GCs) have been widely implemented at all levels of American football participation based on laboratory evidence that they may reduce head impact forces. The purpose of this study was to determine if GC use during practice was associated with a lower risk of sport-related concussion (SRC) during practices and games among high school football players.
Methods: Data were collected on 2610 athletes from 41 Wisconsin schools that self-selected into GC or Non-GC cohorts.
