Rest during the NBA regular season does not improve playoff performance The purpose of this study was to determine if there is a correlation. The purpose of the study was to identify the relationship between pre–NBA career statistical variables and career longevity, measured as the. Research Paper Competition. Presented by: A quantitative look at the relationship between offensive rebounding and transition defense in the NBA.
Vitamin D is believed to play a role in influencing fracture risk and athletic performance. Insufficiency of vitamin D affects an estimated three-quarters of the United States population. Hypovitaminosis D has also been demonstrated to be quite common among professional basketball players in the National Basketball Association NBA.
To determine whether a relationship exists between vitamin D levels and fracture risk and athletic performance as measured by NBA draft status among elite basketball players. Data were obtained from the NBA regarding combine participants from through This information included vitamin D level, demographic information, fracture history, and NBA draft status. The data were analyzed to determine associations between vitamin D level and fracture risk and NBA draft status.
A total of players had a history of at least 1 fracture. Vitamin D level was not predictive of fracture risk. Contrary to our hypothesis, players with a history of stress fracture had a significantly greater mean vitamin D level than those without such history While no significant relationship was found between vitamin D level and fracture history, patients with a history of stress fracture had significantly greater mean vitamin D levels.
Additionally, participants with greater vitamin D levels were more likely to be drafted into the NBA. This information supports the potential role of vitamin D in influencing athletic performance. Vitamin D has proposed roles in bone health, the inflammatory response, immunity, neuromuscular function, carcinoma risk, and overall mortality risk.
In addition to mediating bone health and inflammation, vitamin D may also influence neuromuscular function and athletic performance.
Vitamin D has been shown to influence calcium storage in the sarcoplasmic reticulum, phosphate homeostasis, protein synthesis, and the morphologic features of type II muscle fibers. Myon and colleagues 11 assessed the influence of vitamin D supplementation on the athletic performance of elite ballet dancers. The authors found an These authors found that hypovitaminosis D was present in The clinical significance of hypovitaminosis D in professional basketball players is unknown and requires investigation.
It is possible that low levels of vitamin D may be associated with an increased risk of musculoskeletal injury and stress fracture. Insufficient levels of vitamin D may also affect athletic performance on a neuromuscular level. The purpose of this study was to determine the relationship between vitamin D levels and fracture risk and athletic performance as measured by National Basketball Association [NBA] draft status among professional basketball players.
We hypothesized that players with hypovitaminosis D would have a greater risk of stress fracture and a lower incidence of being drafted into the NBA. The purpose of this study was to determine if there is a correlation between the amount of regular-season rest among NBA players and playoff performance and injury risk in the same season.
We hypothesized that players who rested more frequently during the regular season would perform at a higher level in the playoffs and would miss fewer playoff games because of injury when compared to players who rested less frequently or not at all.
Methods A retrospective cohort analysis was performed by searching the Basketball Reference archives http: Basketball Reference is a credible database that provides NBA player, team, and game statistics, and the data found from this source were cross-checked with the ESPN and Pro Sports Transactions archives http: The following inclusion criteria were applied: When box scores were not available, game and player information was found by searching the Pro Sports Transactions archives for NBA players.
New players were added each season based on these criteria. Thus, some players were included multiple times over the study period.
Based on these inclusion and exclusion criteria, 2 groups were formed: This study was exempt from institutional review board approval. Among all eligible players, matched pairs were formed between players in group A and group B based on the following criteria: The following data were collected and analyzed for each matched pair during the playoffs: In addition to the statistics collected for all matched pairs, steals were also collected for all PGs and SGs, and blocks were recorded for all FCs.
Statistical Analysis The Student t test was used to compare age between all eligible players in group A and group B. Matched-pair t tests were used to compare playoff statistics between the groups. Results A total of NBA players fit the inclusion and exclusion criteria, including players in group A and 67 players in group B Figure 1.
