The aim of this experimental study was to test Wegner’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’ 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 “not to throw the ball’’ 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, SD=2.89) experienced university basketball players. Participants’ 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’ 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’ overall performance changed in ironic fashion across anxiety conditions. Findings 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.

AbstractWheelchair basketball players are classified in four classes based on the International Wheelchair Basketball Federation (IWBF) system of competition. Thus, the aim of the study was to ascertain if the IWBF classification, the type of injury and the wheelchair experience were related to different performance field-based tests. Thirteen basketball players undertook anthropometric measurements and performance tests (hand dynamometry, 5 m and 20 m sprints, 5 m and 20 m sprints with a ball, a T-test, a Pick-up test, a modified 10 m Yo-Yo intermittent recovery test, a maximal pass and a medicine ball throw). The IWBF class was correlated (p<0.05) to the hand dynamometry (r= 0.84), the maximal pass (r=0.67) and the medicine ball throw (r= 0.67). Whereas the years of dependence on the wheelchair were correlated to the velocity (p<0.01): 5 m (r= −0.80) and 20 m (r= −0.77) and agility tests (r= −0.77, p<0.01). Also, the 20 m sprint with a ball (r= 0.68) and the T-test (r= −0.57) correlated (p<0.05) with the experience in playing wheelchair basketball. Therefore, in this team the correlations of the performance variables differed when they were related to the disability class, the years of dependence on the wheelchair and the experience in playing wheelchair basketball. These results should be taken into account by the technical staff and coaches of the teams when assessing performance of wheelchair basketball players.

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.

Physical condition and an optimized diet are relevant to enhance performance and recovery. The diet composition and meal frequency of eleven elite wheelchair basketball players were estimated using a 3-day food-weighing diary in two months during the precompetitive-period. Performance was determined through a 20 m sprint test. The players consumed 4.2 ± 0.8 meals/day in May and 4.5 ± 0.9 meals/day in June, resulting in total energy intakes of 2492 ± 362 kcal/d and 2470 ± 497 kcal/d, respectively. The macronutrient distribution was 3.8 ± 1.3 g/kg carbohydrates, 1.7 ± 0.6 g/kg protein, and 36 ± 5% of energy derived from fat in May, and 4.2 ± 1.9 g/kg carbohydrates, 1.5 ± 0.5 g/kg protein and 32 ± 5% of energy derived from fat in June. The maximum velocity of the sprint test improved from 4.77 ± 0.31 m/s in May to 5.19 ± 0.23 m/s in June. Our results revealed carbohydrate intake below and fat intake above recommendations, but improvements of dietary patterns. Further nutritional advice is necessary to ensure health and performance improvements.

A study was made to initially evaluate whether the age category directly could influence anthropometric measurements, functional movement tests, linear sprint (30 m) and strength. Moreover, and as the main purpose, this study aimed to examine the relationship between the time execution and angles in different changes of direction (COD) test with the analyzed sport performance variables. A total sample of 23 basketball players (age: 17.5 ± 2.42 years; height: 184.6 ± 6.68 cm; body weight: 78.09 ± 11.9 kg). Between-groups’ comparison explored the differences between basketball categories (Junior, n = 12; Senior, n = 11). The COD variables were divided by the time execution into low responders (LR) and high responders (HR) to establish comparisons between groups related to COD time execution. Pearson’s correlation coefficient was used to establish correlations between different CODs and sport performance variables. The results showed a greater influence of age category upon COD performance, especially when the cutting angle was sharper (7.05% [Confidence limits (CL) 90%: 2.33; 11.99]; Quantitative chances (QC) 0/2/98), in which athletes need greater application of strength. Moreover, the sharper the angle or the larger the number of cuts made, the greater the relationship with the vertical force–velocity profile (−42.39 [CL 90%: −57.37; −22.16]; QC 100/0/0%). Thus, the usefulness of the f–v profile to implement training programs that optimize the f–v imbalance and the improvement of the COD performance in basketball players is suggested.
