Influence of a pre-shot dynamic stretching routine on free throw performance

Summary Study aim: The aim of the present study was to examine a single movement of dynamic stretching (SMDS) of the shooting arm as a pre-shot routine for free throw performance (FTP). Material and methods: The sample consisted of 60 junior and senior basketball players from the youth league of Bosnia and Herzegovina (B&H), and the national level – the First Division of B&H. The authors found that some players during a game and training sessions apply an SMDS of the shooting arm as a pre-shot routine for FTP. Since previous literature suggests that length of the routine and pre-performance behaviors are quite different among players of all levels, the sample was divided based on the number of training hours per week (lower/higher number of training hours) and basketball experience (experienced/less experienced). The procedure involves every player performing five free throws (FTs) without prior stretching, five FTs immediately after SMDS of the triceps muscle and five FTs after SMDS of the m. flexor carpi radialis. Results: After the first SMDS (m. triceps brachii) the percentage of FT slightly decreased in the first following attempt. After the second stretching (m. flexor carpi radialis), a significant FT percentage drop was noted in the first following FT for the whole sample. Players with more experience and more training hours per week had poorer results after the stretching. Conclusions: The SMDS routine did not enhance the FTP and it had a rather harmful effect on FTP, especially SMDS of the flexor carpi radialis muscle, and the authors do not recommend SMDS before the FTP.

The Relationship

AbstractThis study attempts to analyze the relationship between free-throw efficiency and the time of arm muscle activation in players from 3 basketball teams with different levels of experience was investigated. During the experiment each player made 20 free throws during which the activation time of his right and left biceps and triceps brachii muscles were measured with the use of surface electromyography and high-speed cameras. Significant differences in muscle activation time (t) during a free throw were found between the groups of basketball players (p = 0.038) (novices: t = 0.664 ± 0.225 s, intermediate-level players: t = 1.15 ± 0.146 s, experts: t = 1.01 ± 0.388 s). In the right triceps brachii muscle in expert basketball players the coefficient of variation (CV) amounted to 44.60% at 81% efficiency, and in novices to 27.12% at 53% efficiency. The time of arm muscle activation during a free throw and its fluctuations vary along with the training experience of basketball players. In all studied groups of players, the variability of muscle activation time in accurate free throws is greater than in inaccurate free throws. Free-throw speed is irrelevant for free-throw efficiency.

And Training

University basketball players (Team A) received quiet eye (QE) training over two seasons of league play, compared to two control teams (Team B and Team C), who competed at the top of the same league but did not receive similar training. QE was defined as the player’s final fixation on the hoop or backboard prior to the shooting action. In Season 1, Team A improved significantly, Pre to Post, in experimental accuracy, QE duration, and relative shot timing but did not transfer these improvements to league play during the season. At the conclusion of Season 2, Team A improved their free throw shooting accuracy by 22.62% to 76.66%, more than Team A (66.18%) or B (74.05%). The results highlight the importance of training a sustained duration of QE on a single location on the hoop prior to the execution of the shooting action. Theoretical and applied implications of training QE are discussed, and recommendations are made for future research and training.

Mobile health encompasses remote and wireless applications to provide health services. Despite the advantages of applying mobile-based monitoring systems, there are challenges and limitations; understanding the challenges may assist in identifying available solutions and optimising decision-making to apply mHealth technologies more practically. This study aimed to investigate the main challenges related to mHealth-based systems for health monitoring purposes. This review was carried out through investigation of English evidence from four databases, including Scopus, PubMed, Embase, and Web of Science, using a defined search strategy from 2013 to 2017. Two independent researchers reviewed the results based on PRISMA guidelines, and data was categorised using a bottom-up approach to reach a framework for the most general challenges. Among the 105 papers obtained, eight works were selected. The revealed challenges were categorised into six main branches across a tree (with 55 nodes, four levels) including user-related, infrastructure, process, management, resource and training challenges. Identifying the resolvable and preventable challenges, such as those related to training, design might play a crucial role in preventing loss of resources and in growing the success rate of a project, particularly if considered in national level projects.

Objectives: This study aimed to examine the proportion of needle stick and sharp injuries (NSSIs) among healthcare workers at King Hussein Medical Center (KHMC), Amman, Jordan. Methods: All NSSI reports referred from departments at KHMC to the Preventive Medicine Department between 2013–2018 were retrospectively reviewed. Proportion of NSSIs were calculated and stratified according to age, gender, job title, place and site of injury and the procedure/task during which the injury occurred. Results: There were a total of 393 NSSIs. A significant association was found between the proportion of NSSIs and all tested variables (P <0.001). The reported proportion of NSSIs was highest among nurses (39.7%) followed by cleaners (36.3%), physicians (10.4%), other workers (7.4%) and lab technicians (5.9%) during the study’s six-year period. Hospital wards were the most common locations (46.1%) where injuries took place. Injuries also occurred most frequently during medical waste collection (38.2%). Conclusion: The proportion of NSSIs was highest among nurses and cleaners. Safety policies and training among high-risk groups should be reviewed to reduce the risk of NSSIs. Multicentre studies at a national level should be conducted to examine whether this study’s findings reflect national trends.Keywords: Needlestick Injuries; Safety; Self Report; Nurses; Accident Prevention; Jordan.
