The Relationship

An investigation was undertaken to assess the relationship between the disability classification levels of wheelchair basketball players, as used by the National Wheelchair Basketball Association (NWBA), and the skill proficiency levels of the athlete. The assessment tool consisted of seven components deemed necessary for proficiency in basketball; these items were the 20-m sprint, free-throw shooting, obstacle dribble, baskets per minute, rebounding, speed pass, and pass for accuracy. The data used for statistical analysis were based upon the results acquired from 91 subjects who were tested in 1983. These subjects represented 18 NWBA teams from 14 states and Canada. The results of the investigation indicate support for placing less of an emphasis on the disability levels of wheelchair basketball participants, and for the development of functional assessment tools to be used in judging performances of “handicapped” athletes.

Purpose: To analyze the relationship between mean propulsive velocity (MPV) of the bar and relative load (percentage of the 1-repetition maximum [%1RM]) in the bench-press (BP) exercise and to determine the relationship of power variables (ie, mean concentric power [MP], mean propulsive power [MPP], and peak power [PP]) in change-of-direction ability, linear sprint, and repeated-sprint ability. Methods: A total of 9 Spanish First Division wheelchair basketball players participated in the study. All participants performed an isoinertial BP test in free execution mode, a 505 change-of-direction ability test, linear sprint test (20 m), and repeated-sprint ability test. Results: A nearly perfect and inverse relationship was observed for the BP exercise between the %1RM and MPV (r = −.97, R2 = .945, P < .001). The maximum loads for MP, MPP, and PP were obtained between 48.1% and 59.4% of the 1RM. However, no significant correlations were observed between strength and wheelchair performance. Conclusions: Wheelchair basketball players with different functional impairments showed a nearly perfect and inverse relationship for the BP exercise between the %1RM and MPV; thus the MPV could be used to estimate the %1RM. This finding has important practical applications for velocity-based resistance training in that coaches would be able to prescribe and monitor training load. Conversely, the absence of association between BP performance and field tests might be due to other factors such as the wheelchair–user interface, trunk-muscle activity, or propulsion technique, apart from strength variables.

The Relationship

Using cadaveric instruction in a graduate-level anatomy course is an expensive and time-consuming undertaking. While this is a worthwhile endeavor, most first-year medical students and students in the health fields struggle with the independent, self-directed learning approach in the cadaveric laboratory, and going beyond rote memorization of the material. As such, effective assessment tools that maximize student learning in the cadaveric laboratory are critical, especially if no lecture component is present. Dissection quality often reflects student attention to detail and therefore may be tied to overall performance in the course. The aim of this study was to investigate the relationship between weekly table quizzes and the overall student outcomes in a graduate biomedical human dissection class as well as examining the benefits and implications of this approach. In this course, a uniquely structured weekly quiz assessed dissection quality and probed student understanding in human anatomy. Student data compiled from 5 years of dissection courses were analyzed to evaluate the relationship between performance in the weekly assessment and on the unit examinations. The results showed a statistically significant relationship between the weekly quizzes and the student examinations at the end of each dissection block in 2013, 2015, 2016, and 2017. The data suggest a potential correlation between performance on weekly quizzes and on unit examinations. The unique nature of the table quizzes provides the students with the opportunity to practice the retrieval of their knowledge, feel more guided throughout their dissection, and receive immediate feedback on their performance. This assessment tool also provides a way to predict student outcomes and an opportunity for early intervention to help at-risk students. The analysis of this research study contributes to the need for more data on the usage of assessment tools in a graduate human dissection class.

elf-efficacy is an assessment of an individual's own ability to organize and perform certain actions necessary to achieve the desired outcomes, and its development is very important. The research aimed to determine whether participation in sports and success in playing sports are associated with more pronounced self-efficacy in people with disabilities, and included two studies. The aim of the first study was to examine the differences in self-efficacy between those who play sports (goalball) and those who do not play sports on a sample of people with visual impairment, as well as whether this difference exists between goalball players of different levels of performance. The aim of the second study was to examine the existence of differences in self-efficacy between wheelchair basketball players and non-wheelchair basketball players. The Generalized Self-Efficacy Scale consisting of ten statements was used as the measuring instrument and the respondents stated how much each item refers to them on a five-point Likert-type scale (from 0 to 4). In data processing the statistical method of the t-test, univariate analysis of variance (One way ANOVA), as well as the Post-Hoc test, were used. The results show that people with disabilities who play sports have more pronounced self-efficacy compared to those who do not play sports, as well as compared to athletes without disabilities. Statistical differences in self-efficacy between athletes with disabilities of different levels of performance have not been identified.

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.

The Relationship

The aim of this experimental study was to test Wegner&rsquo;s (1994) theory of ironic processes in a basketball free throw task under pressure. More specifically, Wegner (1994) predicts that when instructed not to perform in a certain manner performers&rsquo; performance will break down where it is least desired way which is the main hypothesis of the current study. More specifically, it was hypothesized that when basketball players were instructed &ldquo;not to throw the ball&rsquo;&rsquo; into the certain zone on the backboard would decrease their performance in ironic fashion especially under manipulated high-anxiety condition. The sample of the present study comprised 37 male (Mage=22.30,&nbsp;SD=2.89) experienced university basketball players. Participants&rsquo; anxiety was measured using MRF-3 (Krane, 1994). In a basketball free-throw task; the numbers of targets, non-target non-ironic balls and ironic error balls were counted and overall performance was also calculated in order to measure participants&rsquo; performance. Based on the scoring system, participants gained +5 points for throwing into the target, scored -5 points making an ironic error and 0 points for throwing the ball to anywhere (except the target and non-target ironic error zone) on the backboard. Results revealed that when instructed not to throw in a certain zone, performers&rsquo; overall performance changed in ironic fashion across anxiety conditions. Findings&nbsp;suggest that understanding the mechanism of ironic processes of mental control theory may be a useful theoretical framework for examining the relationship between anxiety and performance in sport, physical education and motor control studies.

Three-dimensional kinematic data were obtained from 15 male wheelchair basketball players performing a successful free throw. Players were divided into two groups, according to their International Wheelchair Basketball Federation (IWBF) classification (Group 1: 2-2.5 point players and Group 2: 4-4.5 point players). The angle of release of the ball was 58 for both groups. Group 2 released the ball from a significantly greater height than Group 1 (1.57 – 0.12m v 1.78 – 0.17m; p < .05). Although nonsignificant, the following trends were found: Group 1 showed greater ball release speeds and generated greater angular velocity of the wrist at release while Group 2 generated greater shoulder flexion angular velocity at release. In conclusion, players from different IWBF classes tend to rely on different kinematic strategies to produce successful release conditions.
