Lateral epicondylitis represents a common overuse injury caused by repetitive gestures through sports activity, industrial work and hobby activities. In spite of many conservative treatment procedures, prolonged symptoms and relapse are frequently reported. The goal of our study was to compare the outcome of patients performing an adapted isokinetic eccentric training with that of patients receiving a non-strengthening classical rehabilitation. Results, dealing with pain score evaluation, disability questionnaire, muscle strength measurement and ultrasonographic examination, highlight the relevance of implementing isokinetic adapted eccentric training in the management of lateral epicondylitis.

Undoubtedly, hamstring strains have close connections with the eccentric mode of contraction. Several authors have confirmed the discriminating character of the eccentric isokinetic assessment, in particular using a mixed eccentric hamstrings / concentric quadriceps ratio. Low-intensity eccentric contractions promoting healing of good quality are recommended in the early phase of rehabilitation. Subsequently, strengthening exercises at high intensity contractions will be implemented. Tools to be used and specific modalities of the protocols are discussed in this paper. [less ▲]

Muscles play a key role in active knee stability. ACL reconstruction induces muscle weakness which justifies strength measurements after surgery. Thigh muscle performances under isokinetic conditions can be measured very accurately. Eccentric measurements could implement classical concentric protocols after ACL reconstruction. In order to protect the graft against excessive loads, we avoid post-operative eccentric testing of the quadriceps in our clinical practice. By contrast, hamstring eccentric evaluation is recommended and shows a discriminant character, in particular in the form of a hamstring ecc / quadriceps conc mixed ratio. [less ▲]

This study analyzed sex-specific injury patterns and risk factors in young athletes (n=256) from 12 sport disciplines practicing at the national or the international level in the Grand-Duchy of Luxembourg. Injury occurrence as a result of sport practice was analyzed retrospectively over the year 2006 using a standardized self-administered questionnaire. Overall incidence was not different between girls and boys (1.20 and 1.21 injuries/1000 athlete-hours, respectively), but in the context of team sport competition girls tended to be at a greater risk (rate ratio 2.05, P=0.053). Girls had a higher proportion of injuries in the ankle/foot region compared with boys (34.8% vs 16.8%). No sex-related differences were found regarding injury severity. Multivariate logistic regression (controlling for age and practice volume) revealed that girls' team sports were associated with a greater injury risk compared with individual sports [odds ratio (OR) of 4.76], while in boys this was observed for racket sports (OR=3.31). Furthermore, physical or emotional stress tended to be a specific risk factor in girls. There was a tendency for injury outside sports to be coupled to a higher injury risk in girls and boys. Consideration of sex-specific injury patterns and risk factors could be of importance for effective injury prevention. [less ▲]

In this study, we have investigated the influence of the installation on the dynamometer and of the mode of contraction used during a rotator cuff muscle training. 24 subjects were divided into 3 groups. Two groups of 8 subjects performed a training of the Internal Rotators (IR) in concentric mode (60°/s and 240°/s) and of the External Rotators in eccentric mode (60°/s). The first group was trained at 45° of abduction; the second was trained at 90° of abduction. The third group did not perform any shoulder training. All patients were assessed thanks to the isokinetic device ((3) x 60°/s concentric – (5) x 240°/s concentric – (4) x 60°/s eccentric) before and after training. Only the group trained at 45° of abduction increased the isokinetic maximal peak torque (+ p) in concentric mode during the second isokinetic assessment. No subject showed improvement through the eccentric exercise. They also improved the throw of the ball (+ 8.5 %). Possible feeling of discomfort and signs of subacromial conflict explained that no progression was recorded after training at 90° of abduction. Likewise, the eccentric mode would major the inhibition limiting the strength increase. Even if 90° of abduction seems more specific for assessment, 45° of abduction is more suitable for training.

Besides the concentric classical ratios, the eccentric isokinetic assessment of the muscle shoulder allows us to build some specific ratios. The mixed ratio combines the eccentric maximal contraction of the external rotators (ER) and the concentric maximal strength of the internal rotators (IR). The mixed ratio is frequently decreased among overhead athletes. This imbalance could rise to shoulder tendinopathy, but seemed to be linked with field performance. The functional ratio corresponds to the balance between the ER in concentric mode and the IR in eccentric contraction. The unstable shoulder shows a trend to lower functional ratios, highlighting the weakness of the eccentric IR in that pathology. [less ▲]

The purpose of this study was to compare pure concentric and eccentric isokinetic training with respect to their possible specificity in the progression of strength of the knee flexor and extensor muscles. Subjects were divided into 2 groups (eccentric or concentric training) and performed a specific training of dominant leg. Before and after the training session, isokinetic performances of trained leg and non-trained leg (cross-education) were evaluated. We observed a greater increase of muscle performances after eccentric training. A cross-education effect was measured exclusively after eccentric training session. We showed an increase of maximal eccentric performances after the pure concentric training. No significant progression of maximal concentric performance was measured after eccentric training.

Muscle strength and anaerobic power of the lower extremities are neuromuscular variables that influence performance in many sports activities, including soccer. Despite frequent contradictions in the literature, it may be assumed that muscle strength and balance play a key role in targeted acute muscle injuries. The purpose of the present study was to provide and compare pre-season muscular strength and power profiles in professional and junior elite soccer players throughout the developmental years of 15-21. One original aspect of our study was that isokinetic data were considered alongside the past history of injury in these players. Fifty-seven elite and junior elite male soccer players were assigned to three groups: PRO, n=19; U-21, n=20 and U-17, n=18. Players benefited from knee flexor and extensor isokinetic testing consisting of concentric and eccentric exercises. A context of lingering muscle disorder was defined using statistically selected cut-offs. Functional performance was evaluated throughout a squat jump and 10 m sprint. The PRO group ran faster and jumped higher than the U-17 group (P<0.05). No significant difference in isokinetic muscle strength performance was observed between the three groups when considering normalized body mass parameters. Individual isokinetic profiles enabled the identification of 32/57 (56%) subjects presenting lower limb muscular imbalance. Thirty-six out of 57 players were identified as having sustained a previous major lower limb injury. Of these 36 players, 23 still showed significant muscular imbalance (64%). New trends in rational training could focus more on the risk of imbalance and implement antagonist strengthening aimed at injury prevention. Such an intervention would benefit not only athletes recovering from injury, but also uninjured players. An interdisciplinary approach involving trainers, a physical coach, and medical staff would be of interest to consider in implementing a prevention programme. [less ▲]

CONTEXT: Despite the high rate of lower limb injuries in basketball players, studies of the dominant-limb effect in elite athletes often neglect injury history. OBJECTIVE: To determine lower limb explosive-strength asymmetries in professional basketball players compared with junior basketball players and control participants. DESIGN: Cohort study. SETTING: Academic medical institution. PATIENTS OR OTHER PARTICIPANTS: 15 professional basketball players, 10 junior basketball players, and 20 healthy men. MAIN OUTCOME MEASURE(S): We performed an isokinetic examination to evaluate the knee extensor (Ext) and flexor (Fl) concentric peak torque at 60 degrees .s(-1) and 240 degrees .s(-1) and (Fl only) eccentric peak torque at 30 degrees .s(-1) and 120 degrees .s(-1). Functional evaluation included countermovement jump, countermovement jump with arms, 10-m sprint, single-leg drop jump, and single-leg, 10-second continuous jumping. Variables were compared among groups using analysis of variance or a generalized linear mixed model for bilateral variables. RESULTS: The 2 groups of basketball players demonstrated better isokinetic and functional performances than the control group did. No differences in functional or relative isokinetic variables were noted between professional and junior basketball players. Professional players with a history of knee injury failed to reach normal knee extensor strength at 60 degrees .s(-1). Knee Ext (60 degrees .s(-1)) and Fl (eccentric 120 degrees .s(-1)) torque values as well as 10-second continuous jumping scores were higher in those professional players without a history of knee injury than those with such a history. Compared with the group without a history of knee injury, the group with a history of knee injury maintained leg asymmetry ratios greater than 10% for almost all isokinetic variables and more than 15% for unilateral functional variables. CONCLUSIONS: The relative isokinetic and functional performances of professional basketball players were similar to those of junior players, with no dominant-side effect. A history of knee injury in the professional athlete, however, was reflected in bilateral isokinetic and functional asymmetries and should be considered in future studies of explosive strength.

Objectives: To investigate the cardiovascular responses to standard static assessments of strength and endurance of trunk extensor muscles. Methods: Trunk extensor performances of ten healthy men, 48.2±5.6 years, and 10 healthy women, 49±5.7 years, were assessed by means of a maximum static strength test [consisting in maximal voluntary contractions [MVC] performed with a specific dynamometer], and two static endurance tests [the Sorensen test, and a 50 percent MVC test]. Heart rate [HR], auscultatory systolic [SBP], and diastolic blood pressure [DBP] were recorded throughout the tests. Results: The MVCs induced significant increases of HR and SBP [mean peak values averaging 90 [female] to 95 [male] beats per minute and 133 [female] to 141 [male] mmHg]. The HR, SBP, and DBP values increased significantly across time throughout both endurance static tests. At the end of these tests, mean HR, SBP, and DBP reached 114 to 122 beats per minute, 172 to 185 mmHg, and 112 to 120 mmHg. Genders differed significantly with regard to holding times [longer in females], but a gender effect was only found on SBP [higher in males]. Heart rate and SBP increases were significantly higher in males than in female subjects. Conclusions: The strength test seems less demanding than expected, though our results need to be confirmed. Standard static endurance tests yield sizeable functional stress on the cardiovascular system. Our study emphasizes the need to exclude subjects with cardiac trouble from such efforts and suggests the relevance of monitoring cardiovascular parameters if tests are performed until exhaustion.
