In female basketball the assumed components of success include power, agility, and the proficiency at executing movements using each limb. However, the importance of these attributes in discriminating between playing levels in female basketball have yet to be determined. The purpose of this study was to compare lower body power, change of direction (COD) speed, agility, and lower-body sidedness between basketball athletes participating in Division 1 Collegiate basketball (United States), Women's National Basketball League (WNBL) (Australia), and Women's National Basketball Association (WNBA) (United States)...

This study compared two repeated-sprint ability tests in basketball players. Both tests included 10×30-m sprints, with the difference that the previously validated test (RSA2COD) featured two changes of direction (COD) per sprint, while the experimental test (RSA5COD) featured five CODs per sprint. Tests` performances and metabolic demands were specifically assessed in 20 basketball players. Firstly, RSA5COD test-retest reliability was investigated. Then RSA2COD, RSA5COD sprint times, peak speeds, oxygen uptake (VO2) and post-test blood lactate concentration [La] were measured...

This replication study re-examined the neuropsychological effects of participation in high and low contact youth sports. Modeled after a recently published investigation, two contact sport groups of participants ages 12 to 18 were formed based on the rate of concussion in their respective sport, with the assumption that more head impacts and neuropsychological effects occur in high contact sports that have a greater number of reported concussions as compared with low contact sports. The preseason baseline ImPACT neuropsychological test scores and symptom scores of non-concussed youth athletes in a High Contact Sport (football, n = 139) and a Low Contact Sport (basketball, baseball, soccer, wrestling, volleyball, paddling, and cheerleading, n = 57) were compared...

The objective of this study was to investigate the coordination of a whole-body task (basketball free-throw) in which success in performance outcome can be achieved through a manifold of combinations of postural and movement trajectory configurations. Participants were healthy men (19-24years) with a range of skill levels that were tested for the accuracy of 50 basketball free-throws with both their dominant and non-dominant hand. The trial-to-trial variance in release parameters as well as postural stability of the shooter and synchronization of postural movement and ball release were strong predictors of performance, with non-elite shooters having a higher mean and variability of center-of-mass (COM) speed at the time of ball release...

J Bangsbo
Performance in most sports is determined by the athlete's technical, tactical, physiological and psychological/social characteristics. In the present article, the physical aspect will be evaluated with a focus on what limits performance, and how training can be conducted to improve performance. Specifically how intensified training, i.e., increasing the amount of aerobic high-intensity and speed endurance training, affects physiological adaptations and performance of trained subjects. Periods of speed endurance training do improve performance in events lasting 30 s-4 min, and when combined with aerobic high-intensity sessions, also performance during longer events...

REVIEW
Clyde Williams, Ian Rollo
The common pattern of play in 'team sports' is 'stop and go', i.e. where players perform repeated bouts of brief high-intensity exercise punctuated by lower intensity activity. Sprints are generally 2-4 s long and recovery between sprints is of variable length. Energy production during brief sprints is derived from the degradation of intra-muscular phosphocreatine and glycogen (anaerobic metabolism). Prolonged periods of multiple sprints drain muscle glycogen stores, leading to a decrease in power output and a reduction in general work rate during training and competition...

BACKGROUND: Achilles tendon ruptures are one of the most commonly treated injuries by orthopaedic surgeons and general practitioners. Achilles tendon ruptures have classically been thought to affect the middle-aged "weekend warrior" participating in basketball, volleyball, soccer, or any other ground sport that requires speed and agility; however, with a more active elderly population, these tears are becoming more common in older patients. PURPOSE: To report trends in nonoperative and operative treatment of Achilles tendon tears in the United States from 2005 to 2011 in patients registered with a large Medicare database...
