The Relationship

Patellar tendinopathy is characterized by tendon pain which may reduce the level of performance. This study’s main aim was to compare isokinetic knee strength and jump performances at the start of the sport season between players with patellar tendinopathy and those without. Secondary aims were to assess the relationship between knee strength and jump function. Sixty-two professional basketball players were enrolled (mean age: 25.0 ± 4.0). All players performed knee isokinetic measurements, single leg countermovement jumps, and one leg hop tests. Correlations between knee strength and jump performances were examined. Twenty-four players declared a patellar tendinopathy and were compared to the 38 players without tendinopathy. The isokinetic quadriceps strength was lower in cases of patellar tendinopathy, and a camel’s back curve was observed in 58% of the cases of patellar tendinopathy. However, jump performances were preserved. No link was found between quadriceps and hamstring limb symmetry indexes at 60 and 180°/s with jumps. This preseason screening enabled us to identify the absence of consequences of patellar tendinopathy in professional basketball players. Jump performances were not altered, possibly due to compensatory strategies.

The Relationship Between Muscle Strength, Anaerobic Performance, Agility, Sprint Ability and Vertical Jump Performance in Professional Basketball PlayersThe purpose of this study was to investigate the relationship between isokinetic knee strength, anaerobic performance, sprinting ability, agility and vertical jump performance in first division basketball players. Twelve male first division basketball players participated in this study. The mean age was 25.1 ± 1.7 yrs; mean body height 194.8 ± 5.7 cm; mean body mass 92.3± 9.8 kg; mean PBF 10.1± 5.1; and mean VO2max50.55 ± 6.7 ml/kg/min. Quadriceps and hamstrings were measured at 60° and 180°/s, anaerobic performance was evaluated using the Wingate anaerobic power test, sprint ability was determined by single sprint performance (10-30 m), jump performance was evaluated by countermovement (CMJ) and squat jump (SJ) tests and agility performance was measured using the T drill agility test. Quadriceps strength was significantly correlated with peak power at all contraction velocities. However, for mean power, significant correlation was only found between the 60° left and 180° right knee quadriceps measurements. No measure of strength was significantly related to the measurements from/results of field tests. Moreover, strong relations were found between the performance of athletes in different field tests (p< 0.05). The use of correlation analysis is the limitation of the this study.

Insight Into

Overuse injuries are common in basketball. To gain insight into their etiology and relationship to mechanics, researchers and clinicians need an understanding of the normal biomechanics of the sport. This study was undertaken with this goal in mind. Lower extremity joint kinematics and structural parameters were collected from 24 players from five professional basketball teams as they performed maneuvers typical of their sport. The results indicated that certain common moves such as the layup landing resulted in knee flexion velocities almost double those seen during the landing phase of running. Lateral movements such as cutting and shuffling placed the foot in extreme positions of supination. Both of these findings have implications for injuries common to basketball such as patellar tendinitis and ankle sprains. It is hoped that this information will initiate a database for normal lower extremity kinematics during basketball and lead to a greater understanding of the relationship of lower extremity movement patterns and injury.

Introduction Palpation tenderness is one of the clinical signs used in the diagnosis of patellar tendinopathy (PT). Despite the widespread use of pain pressure thresholds (PPTs) for assessment purposes, it is unknown whether other variables may influence the results of this test and its precision to discriminate between knees with and without PT. Objective To identify the discriminative accuracy of PPTs as a diagnostic test of PT in professional basketball players, used both in an isolated manner and in combination with other tests. Material and Methods An observational study with professional basketball players in which the main variable measured was the PPT, and the secondary variables were the Victorian Institute of Sport Assessment, Patellar tendon (VISA-P) questionnaire and the visual analogue scale (VAS). Age, weight and height were gathered as potential covariates. The receiver operating characteristic (ROC) curve was constructed with the data of the area under the ROC curve (AUC), used to determine the precision of the PPT applied on its own or combined with other secondary variables and covariates. Results In total, 146 patellar tendons of 73 players were analyzed. When analyzing the differences between the PPT of healthy tendons and those with PT, differences were found between the dominant leg and the non-dominant leg. Regarding the cut-off points, the most precise discrimination of a tendon with PT was 8.8 kg/cm2 for an isolated PPT test and 14% for its combination with the VAS. Conclusions This study shows the effectiveness of combining the data from the PPT and the VAS scores. Therefore, both tests should be used for the assessment of PT in professional basketball players, as this combination increases the discriminatory accuracy. Furthermore, these tests are easily applied in clinical practice.
