HOW IMPORTANT IS STRENGTH TRAINING FOR BASKETBALL PLAYERS?
Full text linkIt is well known that strength training can induce notable improvements in muscle force and power production, body composition, and motor control, ultimately leading to en-hancement in sports performance. Previous research has revealed a strong relationship between maximal upper- and lower-body strength and playing time on various levels of basketball competition (e.g, youth, collegiate). Also, greater levels of lower-body strength and power were shown to be positively associated with the players’ ability to compete at higher levels of play (e.g., EuroLeague, NBA). Similarly, greater concentric, eccentric, and isometrics strength were found to be strongly correlated with athletes’ performance on change-of-direction tests (e.g., 505 and T-test). Moreover, the findings of a recently published research report indicat-ed that both male and female basketball players needed to possess adequate levels of upper- and lower-body strength to attain satisfactory free-throw, two-point, and three-point shooting efficiency. Thus, it is of critical importance for sports practitioners to focus on developing and implementing ad-equately periodized strength training programs throughout the full competitive season span to help athletes improve on-court basketball performance
BASKETBALL SHOOTING FUNDAMENTALS: AN IN-DEPTH BIOMECHANICAL ANALYSIS
Full text linkIn the game of basketball, shooting efficiency has a large impact on securing the winning game outcome. However, despite its importance, there is a notable gap in the sci-entific literature focused on examining the biomechanical characteristics of proficient shooters. Thus, a series of re-cently published research reports by Cabarkapa et al. have attempted to address this issue and compare the shooting mechanics between non-proficient and proficient basket-ball shooters
Relationship Between Breakfast and Basketball Shooting Accuracy
No full textPurpose: The purpose of this study was to determine if collegiate and recreational basketball player’s shooting accuracy improved after consumption of breakfast (BF) compared to no-breakfast (No-BF).
Methods: 24 male and female collegiate and recreational basketball players completed a three-week intervention study with a cross-over design. Subjects were randomly assigned to a four-day BF or No-BF treatment and completed testing that included a free-throw drill and timed 2-point and 3-point drills on day four. Treatment switched the following Monday. Food intake records were collected during each treatment phase.
Results: There were no difference between BF and No-BF treatments in amount of shots taken and percentage of shots made during the free-throw, 2-point and 3-point drills. In addition, no difference was observed between BF and No-BF treatment when the number of shots taken during 2-point and 3-point drill was combined. However, there was a significant difference observed between BF and No-BF in mean percentage of shots made during the free throw, 2-point and 3-point drill combined, (BF= 59.2 ± 6.8, No-BF= 48.3±5.4, p-value= 0.000).
Conclusion: Despite the finding that mean shooting percentage was improved when the free-throw, 2-point and 3-point drill were combined, the main finding of the study was that breakfast consumption did not show significant improvement in basketball shooting accuracy when free throw, 2-point and 3-point basketball shooting drills were observed separately

BUILDING BETTER ATHLETES: STRENGTH TRAINING & BASKETBALL PERFORMANCE
No full textBasketball is one of the most popular sports played on various levels of international competition. The fast pace of play resulting in scoring opportunities every few ball possessions, rapid changes in score, and highly athletic motions make this sport appealing to a large audience. In order to properly respond to on-court playing demands (e.g., jumping, sprinting, change-of-direction, shuffling), basketball players need to possess a unique blend of physiological performance attributes, including strength, power, speed, agility, and anaerobic and aerobic capacity. Thus, the aim of this presentation is to: a) provide a brief summary of existing scientific evidence supporting the importance of strength training for optimizing on-court basketball performance, b) present findings from our recently conducted research studies focused on examining the relationship between maximal upper and lower body strength and basketball shooting performance, and c) provide directions for future research pertaining to bridging a gap in scientific literature and advancing training regimens directed towards optimizing on-court basketball performance
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Ground reaction forces during a basketball dunk
No full textBasketball is one of the most popularsports worldwide. The basketball dunkuses a very powerful jumping motion toforcefully push a basketball through a goalpositioned at a height of 10 feet (3.05m). Inthe modern game of basketball, the dunk isvery popular due to its very high field goalpercentage. Due to lack of research on thisevent, the purpose of this study was toexamine the kinetic variables of peak force,peak power, rate of force development,impulse and time during the concentricphase of the five most commonly usedvariations of a basketball dunk: one-leg left(1LL), one-leg right (1LR), two-leg left-right(2LLR), two-leg right-left (2LRL) and two legstationary (2LS). Ten healthy recreationallyactive men (X±SD, age=22.4±2.5,weight=89±6.3kg, height=192.8±4.9cm,vertical jump=73.7±12.4cm) who werecapable of dunking a basketballvolunteered to participate in this researchstudy. Kinetic variables measured in thisstudy were obtained from a force plate anddata acquisition system sampling at1000Hz. Based on our data we concludethat the basketball dunk is a very powerfulactivity that requires high levels of strengthand power. Our data suggest that the mosttime consuming dunk approach was a 2LS(0.820±0.116sec) while the fastest dunkapproach was 1LL (0.311±0.039sec), whichcan serve as a guideline for which dunkshould be utilized at certain times duringan on-court game performance. Thehighest peak power output was observedfor 2LS (6261.9±1104.1W) which also hadthe lowest rate of force development(5851.3±3069.5N/sec) and impulse(408.2±41.1N/sec). The highest peak forceswere observed for 2LLR (3158.4±376.3N)and 2LRL (3206.8±518.2N) dunkapproaches. Knowing the specificbiomechanical characteristics of a motioncan help target optimal training for eachindividual and lead to enhanced basketballperformance, specifically the basketballdunk in this case. In conclusion, this studyserves as a foundation and guideline forfurther research by presenting the previously unexplored kinetic andkinematic variables of a basketball dunk
