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.

Introduction: Non-traumatic neuromuscular lesions of only one muscular portion of the quadriceps are rare and poorly described in literature. Aim: The goal of our study was to investigate the possible causes of this pathology and to objectively quantify the functional consequences of this isolated atrophy from the rectus femoris on the total muscular performances of the quadriceps. Patient and Method: A male patient, 44 years old, presented an isolated atrophy of the right rectus femoris without pain nor history of previous traumatic event. He reported occasional paraesthesias on anterior right thigh. Electromyographic exploration of the lower limbs, imagery (echography and MRI) and isokinetic test were undertaken by the patient. Results: Imagery explorations showed the atrophy of the right rectus femoris combined with fatty degeneration but this exam did not allow determining the actual etiology. Therefore, a precise diagnosis was not allowed, even if the EMG confirmed the presence of important signs of specific and isolated denervation only in the right rectus femoris. The isokinetic test, performed in the classical sitting position, highlighted symmetrical performances for flexors of the knee and a moderately decrease in the right concentric quadriceps torque (-10%). A complementary isokinetic assessment, in a lying supine position, demonstrated a more marked deficit of this right quadriceps (higher than -30%). Conclusion: No precise etiology was shown for this isolated atrophy of the right rectus femoris. Nevertheless, we brought back the importance to lay the patient in a lying supine position in order to preferentially investigate the rectus femoris performances through an isokinetic test. [less ▲]

AIM: The aim of this study was to investigate the ability of isoinertial assessment to monitor training effects. Both parametric and curve analysis of the results were used to underline the specificity of maximal strength and maximal velocity resistance training methods. METHODS: Twenty-four untrained subjects were randomly assigned into three groups: a maximal strength-training group (heavy loads: 80% to 98% of the one repetition maximum [1-RM]), a maximal velocity-training group (light loads: 25% to 50% of 1-RM) and a control group. All the subjects were tested in bench press exercises before and after the 6-week training period. An isoinertial dynamometer was used to assess velocity and power at four increasing loads: 35%, 50%, 70% and 95% of the 1-RM load. Post-test protocol also included a trial at 105% of the 1-RM load. RESULTS: Isoinertial assessment demonstrated for both training groups significant gains at each load. Some specific adaptations appeared: strength training presented a greater increase for average power (+49%, P<0.001) and average velocity (+48%, P<0.001) at 95% of 1-RM, while velocity training emerged as a more effective way to improve performance at 35% and 50% of 1-RM (+11 to 22%) in comparison with strength training (+7 to 12%). The analysis of power and velocity curves specified that strength training enhanced performance earlier in the movement, while velocity training extended the propulsive action at the end of movement. CONCLUSION: The original combination of parametric and curve isoinertial assessment appears to be a relevant method for monitoring specific training effects. The complementarity of both strength and velocity training programmes underlined in this study could lead to practical applications in profiling training programmes. [less ▲]

BACKGROUND: The relationship between muscle injury and strength disorders remains a matter of controversy. PURPOSE: Professional soccer players performed a preseason isokinetic testing aimed at determining whether (1) strength variables could be predictors of subsequent hamstring strain and (2) normalization of strength imbalances could reduce the incidence of hamstring injury. STUDY DESIGN: Cohort study (prognosis); Level of evidence, 1. METHODS: A standardized concentric and eccentric isokinetic assessment was used to identify soccer players with strength imbalances. Subjects were classified among 4 subsets according to the imbalance management content. Recording subsequent hamstring injuries allowed us to define injury frequencies and relative risks between groups. RESULTS: Of 687 players isokinetically tested in preseason, a complete follow-up was obtained in 462 players, for whom 35 hamstring injuries were recorded. The rate of muscle injury was significantly increased in subjects with untreated strength imbalances in comparison with players showing no imbalance in preseason (relative risk = 4.66; 95% confidence interval: 2.01-10.8). The risk of injury remained significantly higher in players with strength imbalances who had subsequent compensating training but no final isokinetic control test than in players without imbalances (relative risk = 2.89; 95% confidence interval: 1.00-8.32). Conversely, normalizing the isokinetic parameters reduced the risk factor for injury to that observed in players without imbalances (relative risk = 1.43; 95% confidence interval: 0.44-4.71). CONCLUSION: The outcomes showed that isokinetic intervention gives rise to the preseason detection of strength imbalances, a factor that increases the risk of hamstring injury. Restoring a normal strength profile decreases the muscle injury incidence. [less ▲]

Despite the essential role played by the scapula in shoulder function, current concepts in shoulder training and treatment regularly neglect its contribution. The 'scapular dyskinesis' is an alteration of the normal scapular kinematics as part of scapulohumeral rhythm, which has been shown to be a nonspecific response to a host of proximal and distal shoulder injuries. The dyskinesis can react in many ways with shoulder motion and function to increase the dysfunction. Thoracic kyphosis, acromio-clavicular joint disorders, subacromial or internal impingement, instability or labral pathology can alter scapular kinematics. Indeed, alteration of scapular stabilizing muscle activation, inflexibility of the muscles and capsule-ligamentous complex around the shoulder may affect the resting position and motion of the scapula. Given the interest in the scapular positioning and patterns of motion, this article aims to give a detailed overview of the literature focusing on the role of the scapula within the shoulder complex through the sports context. Such an examination of the role of the scapula requires the description of the normal pattern of scapula motion during shoulder movement; this also implies the study of possible scapular adaptations with sports practice and scapular dyskinesis concomitant to fatigue, impingement and instability. Different methods of scapular positioning evaluation are gathered from the literature in order to offer to the therapist the possibility of detecting scapular asymmetries through clinical examinations. Furthermore, current concepts of rehabilitation dealing with relieving symptoms associated with inflexibility, weakness or activation imbalance of the muscles are described. Repeating clinical assessments throughout the rehabilitation process highlights improvements and allows the therapist to actualize rationally his or her intervention. The return to the field must be accompanied by a transitory phase, which is conducive to integrating new instructions during sports gestures. On the basis of the possible scapular disturbance entailed in sports practice, a preventive approach that could be incorporated into training management is encouraged. [less ▲]

The isokinetic testing has been found to be useful for quantifying the recovery of shoulder strength after repair of the rotator cuff. Measurements focus in particular on bilateral asymmetry and agonist / antagonist imbalance. Frequently, more than one year is needed for the recovery of muscle strength performances. The dynamometer may also be used as a rehabilitative device, even if the isokinetic training conditions remain sparse in literature. [less ▲]
