Bovine muscle biopsies were analysed for fiber type and capillary density by the acid ATP-ase and amylase-PAS methods respectively. Samples obtained from Belgian blue double muscled (DM) calves were compared for their fibre type, size and vascularization with samples from Friesian (F) calves. The animals were sampled both at 2 and 7 months of age. Changes in histochemical composition occurring with ageing, independently of the breed, and differences related to the muscle sampled by comparing biopsies obtained from the longissimus dorsi (LD) and gluteobiceps (GB) muscles in animals of both breed were also investigated. Independently of age and muscle, fibre type I percentage and area were significantly higher in F than in DM muscles. Type IIa area was significantly larger in F than in DM, while fibre type IIb percentage and area were higher in DM. The number of capillaries/mm2 was significantly higher in F than in DM. Fibre type IIa and IIb percentage as well as the diameter of the three fibre types was significantly higher in the oldest animals. Finally, independently of age and breed, fibre type I and IIb percentages were significantly higher in LD but lower in GB. The results mainly demonstrated that Belgian blue DM muscles present a higher proportion of IIb fibres and a lower capillary supply than F muscles. [less ▲]

Objectives. To compare muscle performance in women with fibromyalgia and in healthy women. Patients and methods. Sixteen women with fibromyalgia syndrome (FMS) and 85 healthy women who were physically inactive or engaged in recreational sports underwent measurements of four parameters: maximal concentric isokinetic muscle strength of the knee extensors and flexors in the dominant limb, isometric grip strength on a Colin dynamometer, muscle fatigue resistance during 30 maximal concentric isokinetic contractions of the dominant knee flexors and extensors at 180° angular velocity, and static endurance during posture maintenance. Results. All muscle variables were decreased in the FMS patients as compared to the controls.The decreases were more marked during aerobic than during anaerobic exercise.Mean decreases were 39% (P<0.001) for muscle strength, 40% (P<0.0001) for fatigue resistance, and 81% (P<0.0001) for static endurance. Pain during exercise as evaluated using a visual analog scale was more marked in the FMS patients. Conclusion. This study of the three pathways supplying energy to muscle confirms that muscle function is globally impaired in FMS patients.The results suggest that the impairment predominates on aerobic processes.

The use of muscle relaxants, considered until recently as common practice in current neurosurgical anaesthesia protocols, becomes increasingly more questionable today. The reasons rely on the evolution of neurosurgery including the advent of new surgical techniques, the evolution of anaesthesia having the benefit of new drugs and devices, and the rationale for using muscle relaxants balanced against their potential side-effects and possible pharmacodynamic alterations in neurosurgical patients.

Bone repair failure is a major complication of open fracture, leading to non-union of broken bone extremities and movement at the fracture site. This results in a serious disability for patients. The role played by the periosteum and bone marrow progenitors in bone repair is now well documented. In contrast, limited information is available on the role played by myogenic progenitor cells in bone repair. In a recent article published in BMC Musculoskeletal Disorders, Liu et al. compared the presence of myogenic progenitor (MyoD lineage cells) in closed and open fractures. They showed that myogenic progenitors are present in open, but not closed fractures, suggesting that muscle satellite cells may colonize the fracture site in the absence of intact periosteum. Interestingly, these progenitors sequentially expressed a chondrogenic and, thereafter, an osteoblastic phenotype, suggestive of a functional role in the repair process. This finding opens up new perspectives for the research of orthopedic surgical methods, which could maximize myogenic progenitor access and mobilization to augment bone repair.

Investigating factors associated with muscle strains highlight the multifactorial origin of the injury and the difficulty of identifying isolated or combined factors that caused the injury. Among the numerous causes reported in the literature, only a few have been scientifically associated with injury occurrence, while others have been empirically suggested. Contradictions in articles dealing with muscle strength and imbalance are frequent, and are probably the result of differences in methodology and criteria for patient inclusion. Imbalance in muscle strength commonly refers to abnormal bilateral asymmetry (between homologous groups) and a disruption of the agonist-antagonist ratio. Some authors who focus on a history of hamstring or adductor strains have demonstrated the frequent abnormality of muscle strength and balance by means of isokinetic assessment. Mixed ratios, combining the eccentric performance of “decelerating” muscles (such as the hamstrings) and the concentric performance of “mobiliser” muscles (such as the quadriceps) are suggested and seem relevant. An increased emphasis on eccentric strengthening exercises, particularly for the hamstrings, and ratio correction on the basis of statistically selected cut-offs, significantly reduces the recurrence rate of the injury and lingering complaints upon return-to-sport. Similarly, isokinetic interventions, as a preseason screening tool in sports where there is a high rate of muscle strain injuries, could detect imbalances early and thus promote a preventive strategy.

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 ▲]
