Influence of Weight Bearing Dorsiflexion (WBDF) on Ankle Injury History Among Semi-professional Recreational Basketball Players

Ankle injuries are one of the most common occurrences in the field of sports. Weight bearing dorsiflexion range can be an effecting factor in ankle injuries. Weight bearing lunge test is used to assess weight bearing dorsiflexion. By using this test as a standard testing protocol, it is possible to minimize development of further sport related ankle injuries. But this test for basketball players with ankle injuries has not been studied yet. The current study will aim to examine the weight bearing dorsiflexion of basketball players related to their gender, ankle injury history and leg dominance. A quasi-experimental design study was conducted. Thirty-four (34) participants were recruited and initially and two (2) were excluded. 18 participants were male and 14 were female basketball players in Colombo Blues and Kotelawala Defence University basketball teams. The average of age of the sample was 21.8 years. Demographic data, information about training time, injury history of the participants was obtained using an interview administered assessment form. The Weight Bearing Dorsiflexion was measured using digital inclinometer. Findings indicated that the weight bearing dorsiflexion range is smaller than that of males (p>0.05). There was a significant difference in weight bearing dorsiflexion and ankle injury history (p<0.01) among players. Significant differences were seen in influence in leg dominance to weight bearing dorsiflexion (p<0.05). This is the first study that is investigated weight bearing dorsiflexion among basketball players in Sri Lanka. No significant difference was found between gender and weight bearing dorsiflexion. A significant difference was determined between ankle injury history and weight bearing dorsiflexion. Furthermore, a significant difference was found in leg dominance and weight bearing dorsiflexion.

Aerobic capacity and respiratory patterns are better in recreational basketball-engaged university students than age-matched untrained males

Study aim: To asses and compare the aerobic capacity and respiratory parameters in recreational basketball-engaged university students with age-matched untrained young adults. Material and methods: A total of 30 subjects were selected to took part in the study based on recreational-basketball activity level and were assigned to a basketball (BG: n = 15, age 22.86 ± 1.35 yrs., body height 185.07 ± 5.95 cm, body weight 81.21 ± 6.15 kg) and untrained group (UG: n = 15, age 22.60 ± 1.50 yrs., body height 181.53 ± 6.11 cm, body weight 76.89 ± 7.30 kg). Inspiratory vital capacity (IVC), forced expiration volume (FEV1), FEV1/IVC ratio, maximal oxygen consumption (VO2max), ventilatory threshold (VO2VT) and time to exhaustion, were measured in all subjects. Student T-test for independent Sample and Cohen’s d as the measure of the effect size were calculated. Results: Recreational basketball-engaged students (EG) reached significantly greater IVC (t = 7.240, p < 0.001, d = 1.854), FEV1 (t = 10.852, p < 0.001, d = 2.834), FEV1/IVC ratio (t = 6.370, p < 0.001, d = 3.920), maximal oxygen consumption (t = 9.039, p < 0.001, d = 3.310), ventilatory threshold (t = 9.859, p < 0.001, d = 3.607) and time to exhaustion (t = 12.361, p < 0.001, d = 4.515) compared to UG. Conclusions: Long-term exposure to recreational basketball leads to adaptive changes in aerobic and respiratory parameters in male university students.

Plantar Pressure Profiles and Possible Foot Syndromes of the Taiwanese College Elite Basketball Players

Background: Plantar pressure assessment are useful for understanding the functions of the foot and lower limb and predicting injury incidence rates. Musculoskeletal fatigues are likely to affect the results of plantar pressure profiles. This study aimed at characterizing college elite basketball players' plantar pressure profiles and pain profiles during static standing and walking. Methods: Fifty-one male elite basketball players and eighty-five male recreational basketball players participated in this study. An optical plantar pressure measurement system was used for collecting the arch index (AI), regional plantar pressure distributions (PPDs), and footprint characteristics during static and dynamic activities. Elite basketball players' pain profiles were examined for evaluating their common musculoskeletal pain areas.Results: The AI values in recreational basketball players fell in the normal range, whereas was considerably lower in elite basketball players. Elite basketball players' static PPDs of both feet were mainly exerted on the lateral longitudinal arch and the lateral heel, and relatively lower on the medial longitudinal arch, the medial and lateral metatarsal bones. The PPDs mainly transferred to the lateral metatarsal bone and lateral longitudinal arch, and decreased at the medial heel during the midstance phase of walking. The footprint characteristics of elite basketball players illustrated the features of the calcaneal varus (supinated foot) of high arches and the dropped cuboid foot. The lateral ankle joints and anterior cruciate ligaments were the common musculoskeletal pain areas. Conclusions: Elite basketball players' AI values was found to be high arches, and their PPDs tended to parallel the features of the high-arched supinated and dropped cuboid foot. Their pain profiles not only resonated with the common basketball injuries, but also reflected the features of the Jones fracture and cuboid syndrome. The potential links among high-arched supinated foot, Jones fracture and cuboid syndrome are worth further studies.

Effects of Attentional and Motivational Priming on Athletic Performance

The effect of motivational and attentional primes on athletic performance was assessed. Thirty-four male, recreational basketball players shot 10 free throws after completing a word scrambled sentence task that primed either autonomous motivation, fluency, or nothing (control). Results revealed that neither prime significantly increased free throw scores more than the control, but fluency primed participants scored significantly more free throws than autonomous motivation primed participants. Results provide support that athletes should try to relax during high pressure situations that require precision. Focusing on the task at hand will hinder performance, while naturally going through the motions will enhance performance. Results also provided support that there is an optimal level of arousal for performing one’s best. Too low or too high of arousal actually hinders an athlete’s performance.

Playing Through Pain and Injury: Psychosocial Considerations

The purpose of the present investigation was to assess the influence of gender and athletic identity on recreational basketball players’ attitudes and behaviors with regard to playing through pain and injury. Participants included 130 male and female intramural basketball players who completed the Athletic Identity Measurement Scale (AIMS), the Risk Pain and Injury Questionnaire (RPIQ), and a scale to measure behavioral tendencies toward playing with injury. Results from MANOVA and hierarchical regression analyses revealed that gender was not a factor in regard to either injury-related attitudes or behavioral tendencies. In contrast, athletic identity was a significant factor. Specifically, athletes who were higher in athletic identity exhibited more positive attitudes toward playing with injury as well as higher behavioral tendencies to do so. Study results are discussed in terms of the sport culture and sport ethic surrounding injury.
