Introduction: Different series emphasized the necessity of rehabilitation program after infiltration of platelet-rich plasma (PRP) in case of tendinopathy. However, most of them describe only briefly the reeducation protocol and these programs vary. Our aim was to extensively describe a specific standardized rehabilitation program. Methods: After a review of literature of post-PRP infiltration protocols, we had developed a standardized rehabilitation protocol. This protocol was evaluated by 30 subjects with chronic jumper’s knee who. A a standardised progressive sub-maximal eccentric program supervised by a physical therapist for 6 weeks was started 1 week post-infiltration. The patient benefited also from electromyostimulation, isometric strengthening and stretching of the quadriceps, cycloergometer and cryotherapy. After the supervised program, the patient had to make an auto-reeducation added to the reathletisation protocol for 6 more weeks which was followed by maintenance exercises up to 1 year. The assessments were made using a VAS, IKDC and VISA-P scores. Results: The VAS , IKDC and VISA-P scores decreased very significantly with time. The compliance to auto-reeducation was good. Conclusion: We proposed a simple and efficient protocol based on sub-maximal eccentric reeducation to add to PRP infiltrations in case of patellar tendinopathy. [less ▲]

The aim of this study was to examine absolute and relative reliability of fatigue measures calculated from peak torque or total work during 20, 30, 40 and 50 reciprocal maximal concentric contractions performed on an isokinetic dynamometer at 180 ° · s " 1 . Eighteen moderately active men performed 50 reciprocal maximal concentric contractions on three occasions with one 7 – 10 days recovery between each session. Peak torque and total work were computed for each contraction and subsequently summed to compute cumulated performance after respectively 20, 30, 40 and 50 repetitions. Muscle fatigue was determined after 20, 30, 40 and 50 repetitions by the fatigue index, the percent decrease in performance and the slope. Reliability of average peak torque or average total work was similar and was not a! ected by the lengthening of the protocol, although a learning e! ect was evident for knee flexors. Reliability of fatigue measures calculated from peak torque or total work was similar, improved with the lengthening of the protocol and was better for knee extensors. Measuring average peak torque or average total work and the slope during a protocol involving 30 maximal reciprocal concentric contractions appear to represent a better compromise between reliability and physiological interpretability of the data.

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.

Objectif Mettre au point une épreuve de quantification de l'activité physique journalière de la population générale en vue, d'une part, d'envisager des mesures préventives en matière de promotion de la santé et, d'autre part, d'établir des données normatives confrontables à celles de populations souffrant d'affections diverses (ostéo-articulatoires, rhumatologiques, chroniques, … ). Patients et Méthodes La population étudiée comporte 84 sujets volontaires sains, âgés de 20 à 80 ans et répartis en classe d'âge par décade. Le monitoring d'activité physique est réalisé durant 24 heures à partir du Sense Wear® Armband (composé d'un accéléromètre et de capteurs thermiques) porté au niveau du bras en l'absence de toute gêne particulière. Ce dispositif enregistre sur une période de 24 heures la dépense énergétique totale (Kcal), le nombre de pas, l'intensité moyenne d'effort en équivalent métabolique (MET), ainsi que la dépense énergétique réalisée à différents niveaux d'intensité d'activités physiques : 0 à 1 MET, 1 à 2 MET, 2 à 3 MET, > à 3 MET, > à 6 MET, … Les sujets sont en outre soumis au « Minnesota Leisure Time Physical Activity Questionnaire » (MLTPAQ). Résultats Nous observons une réduction significative de la dépense énergétique enregistrée durant 24 heures avec l'augmentation de l'âge. La classe d'âge 31-40 ans semble la plus dynamique comme en atteste l'intensité moyenne d'effort sur 24 h (1,7 MET), la dépense énergétique enregistrée lors d'activités supérieures à 6 MET et le nombre de pas parcourus sur 24 h. De façon originale, nous constatons que la dépense énergétique pour des activités comprises entre 0 et 1 MET augmente significativement avec l'âge alors que le phénomène inverse apparaît pour les activités supérieures à 6 MET. Un constat alarmant concerne le manque d'activités physiques actives (supérieures à 3 MET) constaté au sein de la population générale. Des corrélations significatives s'observent entre les différents paramètres enregistrés à partir du Sense Wear® Armband et diverses données issues du questionnaire MLTPAQ. Discussion L'établissement de données normatives en termes d'activités physiques journalières à partir de ce protocole original s'avère particulièrement pertinent dans le cadre du suivi fonctionnel de la population générale mais aussi de multiples populations pathologiques. Conclusion La poursuite de ces recherches dégage des perspectives en vue de la mise en place de mesures préventives en matière de promotion de la santé mais aussi dans la caractérisation du statut fonctionnel ou encore le suivi longitudinal d'un patient souffrant d'affections diverses.
