Sudden death is defined as unexpected death as a result of natural causes (non traumatic, nonviolent) in which a loss of all functions occurred instantaneously or within 1 hour of the onset of collapse symptoms. Sudden death was considered to be cardiovascular (SCD) in origin when at postmortem the primary cause leading to cardiac arrest was found in the heart or great vessels and other non-cardiac causes were excluded.
The American Heart Association
currently recommends a physical exam and family history questionnaire as a first-line screening, with further examination based on the results of those initial steps.
It is difficult to give an accurate answer to this question since there are many factors that affect on this such as: age, gender, height, playing position, muscle mass and bone mass.
Recovery is a major challenge for the elite athlete, who undertakes two or even three workouts each day during certain phases of the training cycle, with 4 to 24 hr between each session. Recovery involves a complex range of processes of restoration and adaptation to physiological stress of exercise, including these:
"Female Athlete Issues for the Team Physician," published in the American College of Sports Medicine publication, "Medicine & Science & Sports and Exercise," in 2003, provides an overview of select musculoskeletal and medical issues that are important to team physicians who are responsible for the medical care of female athletes.
Although some may perceive sports-related injuries to be unavoidable and simply a part of the game, these occur in predictable patterns and many are preventable through the implementation of targeted interventions. As detailed previously, the two most problematic injuries in basketball are related to the ankle and knee. As a result, numerous studies had been conducted to evaluate different intervention strategies and different protective equipment in preventing injuries of these body parts.
Basketball is one of the most popular sports, and it is also one of the highest contributors to sport and recreation-related injuries.  As the sport grows, in terms of number of participants and intensity, so does the number of injuries. In 2006 FIBA (Fédération Internationale du Basketball Association) has estimated that 11% of the world´s population plays basketball.
It has been reported that approximately half of all basketball injuries occur in the key, where crowding, jumping, and body contact are common. It was found that injuries in this region accounted for 44.7% of reportable injuries. 
More injuries are sustained during competition than during training sessions. In a 16-year review of men's and women's college basketball in the USA, it was found that the rate of injuries in games was two times greater than in practice.
A three-years study by the EuroSafe -Safety in Sports Task Force confirms that it is possible to anchor injury prevention more strongly into the education and training of coaches as well as players and thus to increase the health benefits of playing basketball by decreasing injury risks.
Coaches play a decisive role in translating the prevention evidence into practice and are the most important mediators for integrating safety aspects within current training and practices. The study report on the pilot has been launched in collaboration with FIBA Europe.
In this study we evaluated the level of stress in basketball referees and their performance in the court in terms of how much time they spent in running, walking and standing during the games. We used these parameters to evaluate correlation between performance during the game and level of stress and burnout syndrome among referees.
According to the International Olympic Committee's recommendations from the last XIII Olympic congress regarding organization of educational programmes for athletes, we conducted surveillance about knowledge and attitudes of the basketball players in 3 important topics: doping, nutrition and injuries. Since 2003 there is almost tripled number of doping controls in basketball and decreased number of positive doping cases, but basketball players are still in the group of risky sports.
Many study results suggest that inadequate hydration is influencing sports performance by: impairing mental/cognitive performance, decreasing the motivation to exercise, increasing the rating of perceived exertion and decreasing the time to exhaustion. In basketball dehydration is correlated with overall basketball performance, jumps, shooting and number of shots that were attempted and made. The aim of our study was to analyze the influence of hydration on basketball performance.
Hydration is the condition of having adequate fluid in the body tissues. Field research suggests that approximately 50% of individual and team athletes are hypohydrated. Thus, the aim of this study was to analyze the hydration status of male basketball players.
The amount and type of substances that basketball players use is mainly unknown. A benefit of supplementation and medication use in sport is still controversial. Although some supplements could improve athletic performance and prescribed drugs are necessary in treatment of sports injury, inappropriate and excessive use could increase the number of adverse drug events and interactions.
