The purpose of the present study was to compare chosen physical fitness characteristics of Turkish professional basketball players in different divisions (first and second division) and playing positions. Forty-five professional male basketball players (14 guards, 15 forwards, 16 centers) participated in this study voluntarily. For each player, anthropometric measurements were performed, as well as a multi-stage 20 m shuttle run, isokinetic leg strength, squat jump (SJ), countermovement jump (CMJ), 10–30 meter single-sprint and T-drill agility tests. The differences in terms of division were evaluated by independent t-test and the differences by playing position were evaluated by one-way ANOVA with Post Hoc Tukey test. First division players’ CMJ measurements were significantly higher than those of second division players’ (p≤0.05), whereas second division players’ 10 m sprint times were significantly better than those of first division players’ (p≤0.05). In addition, forwards and centers were significantly taller than guards. Centers were significantly heavier and their T-drill test performances were inferior to those of forwards and guards (p≤0.05). Moreover, guards had a significantly higher maximal oxygen uptake (VO2 max) than centers. Guards and forwards showed significantly better performance in the 10 and 30 m sprint tests than centers (p≤0.05). Forwards and centers had significantly better left leg flexor strength at 180°.s−1(p≤0.05). In conclusion, the findings of the present study indicated that physical performance of professional basketball players differed among guards, forwards and centers, whereas there were not significant differences between first and second division players. According to the present study, court positions have different demands and physical attributes which are specific to each playing position in professional basketball players. Therefore, these results suggest that coaches should tailor fitness programs according to specific positions on the court.

The purpose of this study was to compare the blood lactate (La-), heart rate (HR) and percentage of maximum HR (%HRmax) responses among the small-sided games (SSGs) in elite young soccer players. Sixteen players (average age 15.7 6 0.4 years; height 176.8 6 4.6 cm; body mass 65.5 6 5.6 kg; VO2max 53.1 6 5.9 ml · kg(-1) · min(-1); HRmax 195.9 6 7.4 b · min(-1)) volunteered to perform the YoYo intermittent recovery test and 6 bouts of soccer drills including 1-a-side, 2-a-side, 3-a-side, and 4-a-side games without a goalkeeper in random order at 2-day intervals. The differences in La-, HR and%HRmax either among the SSGs or among the bouts were identified using 4 x 6 (games x exercise bouts) 2-way analysis of variance with repeated measures. Significant differences were found on La-, HR, and %HRmax among the bouts (p ≤ 0.05). The 3-a-side and 4-a-side games were significantly higher than 1-a-side and 2-a-side games on HR and %HRmax (p ≤ 0.05), whereas the 1-a-side game significantly resulted in higher La- responses compared to other SSGs. This study demonstrated that physiological responses during the 1-a-side and 2-a-side games were different compared to 3-a-side and 4-a-side games. Therefore, it can be concluded that a decreased number of players results in increased intensity during SSGs including 6 bouts. These results suggest that coaches should pay attention on choosing the SSG type and the number of bouts to improve desired physical conditioning of elite young soccer players in soccer training.

The purpose of this study was to compare heart rate (HR) response and frequency of technical actions between half-court and full-court 3-a-side games in female high school basketball players. Twelve young female basketball players (age 15.5 ± 0.5 years; height 165.1 ± 5.7 cm; body mass 57.3 ± 7.2 kg; training age 4.2 ± 0.7 years; HRmax 202.9 ± 5.6 b·min(-1)) participated in this study voluntarily. On the first day, anthropometric measurements (height and body mass) were taken for each player; this was followed by the Yo-Yo intermittent recovery test (YIRT) level 1 for the subjects. Then, half-court and full-court 3-a-side games were organized in random order at 2-day intervals. The HRmax for each player was determined during the YIRT, after which the HR was measured during the 3-a-side games. In addition, the frequencies of different categories of technical actions were counted manually during the 3-a-side games. A paired t-test was calculated for each dependent variable, including HR, percentage of maximum HR (%HRmax), and the frequencies of different technical actions to compare half-court and full-court 3-a-side games. The study results indicate that the full-court 3-a-side games produced significantly higher responses than the half-court 3-a-side games in terms of HR and %HRmax (p < 0.05), whereas the half-court games resulted in significantly higher frequencies of technical actions (p < 0.05). The results of this study suggest that, if coaches want to achieve greater HR responses, coaches of female high school basketball players should organize full-court 3-a-side games, whereas coaches who want to focus on technical actions should arrange half-court 3-a-side games.

Abstract.[Purpose] The aim of this study was to determine the functional level of activity and postural control after rehabilitation of anterior cruciate ligament reconstructed knees and compare them with nonoperated limbs and healthy limbs in control subjects.[Subjects] Twenty-seven patients participated in the study: 17 had undergone reconstruction with a bone-patellar tendon-bone and 10 with a semitendinosus graft technique. The same rehabilitation protocol was used for all of the patients. Besides the patients, 18 healthy volunteers participated as a control group. [Results] There were no significant differences for the eyes open static stabilometry test between operated and non-operated limbs of the patients. On the other hand, there were statistically significant differences for the closed eyes static balance test between the operated and non-operated limbs at 3 and 6 months after surgery. There were significant differences for the eyes open static balance test between the 3rd and 6th, and 6th and 12th months and for the eyes closed test of non-operated limbs between the same months as well. No statistically significant differences were noted in the dynamic balance tests between the patients and the control group. Lysholm scores of the patients obtained at 6 and 12th months after surgery were significantly better than those at 3 months after surgery. Different operation techniques revealed no significant differences in any test performed at any time.[Conclusions] Performing a postoperative sportive rehabilitation including specific proprioceptive training sessions has positive effects both on clinical status and postural control of the patients.

Errors in references still appear in current physical therapy and rehabilitation literature, but most are not severe.

Abstract.[Purpose]The purpose of this study was to examine the association between the radiographic stages of knee osteoarthritis and measurements of symptoms.[Subjects] One hundred eighty-three patients with radiographs of varying degrees of osteoarthritis of the knee and 35 healthy subjects with no osteoarthritis of the knee were assessed.[Methods] The participants were assessed using the Hospital for Special Surgery score, pain score, sit-to-stand test, manual muscle test, goniometry and the KellgrenLawrence score.[Results] While pain scores of grades I and II in the Kellgren-Lawrence score were similar to each other, they were less than the pain scores of grades III and IV. Muscle strength, function scores and range of motion of grades I and II were similar and they were also higher than the values of grades III and IV. Pain scores of grades III and IV were similar whereas muscle strength, range of motion and function scores of grade IV were lower than those of grade III. While there was no difference between the functional levels of grade II and III, they were both lower than the values of grade I but higher than the values of grade IV.[Conclusion] The radiological findings did not show very strong relationships with other symptoms and signs of the disease in osteoarthritic patients.
