AbstractWe investigated the effects of sling-based, suspended push-up training on muscle size and function of upper limb and abdominal muscles. Eight men conducted suspended push-ups to failure 3 sets/session, 3 sessions/week, for 8 weeks. The maximum number of push-ups during training gradually and significantly increased from the first to last training session (+92%), suggesting improved muscle endurance. After the training, muscle thickness of the elbow extensors (+16%) and flexors (+3%), as well as abdominal muscles (rectus abdominis: RA,+27%; external oblique: EO,+14%) significantly increased. No changes occurred in maximum isometric strength of elbow extension or flexion, nor in 1-repetition maximum bench press. In a follow-up experiment, electromyograms (EMGs) of RA, EO and internal oblique (IO) during suspended push-ups to failure were measured and normalized to those during maximum voluntary contraction of each muscle (% EMGmvc) in six men. EMG significantly increased when reaching failure in all muscles (RA: 46–88%, EO: 32–50%, IO: 19–52%, start-end), and was particularly high in RA. These results suggest that suspended push-up training can augment size of not only upper limb but also abdominal muscles, likely attributable to high muscle activities during exercise; however, this does not necessarily improve maximum strength after training thus warrants careful interpretation/application.

Introduction: Breast cancer is the most common type of cancer among women in Brazil and in the worl. The surgical treatment procedure may cause severe morbidity in the upper limb homolateral to surgery, including the reduction of the range of motion, with consequent impairment of function. A physiotherapeutic approach has an important role in the recover range of motion and the functionality of these women, guaranteeing the occupational, domestestic, familiar and conjugated activities, and, in this way, also improving the quality of life. Objectives: To analyse chances in the shoulder's range of motion and the functional capacity of the upper limbs, promoted by the deep running procedure in women with late postoperative mastectomy. Methods: All the patients were submitted to an evaluation in the beginning and end of the treatment, including: goniometry of flexion, extension, abduction, adduction, internal and external rotation of the shoulder joint; and function capacity analysis in activities that involve the upper members by DASH questionnaire. The treatment protocol includes twelve sessions of deep running, realized twice a week, in deep pool, for 20-minute during six weeks. Results: Were submitted to treatment a total of 4 patients. Despite the improvement in the numerical values, statistically significant differences were not found on the range of movements and in the functional capacity of upper members before and after the deep running sessions in post-mastectomy women. Conclusion: Deep running had effects on the numerical values of range of movement and upper limb functionality in women in the late postoperative period of the mastectomy procedure, but without statistically significant differences.

The orbicularis oculi muscle is the sphincter muscle of the eyelids that blinks and closes the eyes. In this review, our aim was threefold: (1) to introduce the performance characteristics of blinking activity in young and older adults, (2) to discuss the influence of aging on the orbicularis oculi muscle in healthy adults, and (3) to provide information about the effect of facial exercise training on the orbicularis oculi muscle. To achieve the purpose of this review, a search using two electronic databases (PubMed and Scopus) and a search engine (Google Scholar) was conducted. The amplitude and peak velocity of spontaneously blinking behavior, which is an index of muscle function of the orbicularis oculi, appear to be affected by aging. The muscle thickness of the orbicularis oculi tends to be low in older adults, but there are issues that need to be examined further, such as differences in sex and measurement positions. There was no study on the effect of exercise training; however, the results of a highly trained man indicate that the orbicularis oculi muscles might elicit muscle hypertrophy through non-traditional resistance exercise.

Context: Knowing the possible association between the isometric strength of the shoulder rotators, scapular muscles, and the Y-balance test upper quarter (YBT-UQ) performance could help identify which indicators of shoulder stability should be considered in this field test. This study aimed to determine whether the isometric strength of the shoulder rotators and scapular muscles is associated with the YBT-UQ performance of the dominant upper limb in amateur volleyball players. Design: Cross-sectional study. Methods: A convenience sample of 22 male and 18 female volleyball players (≥12 h of training/week) between 18 and 26 years of age. The isometric strength of the middle trapezius, lower trapezius, serratus anterior, internal, and external rotator muscles was assessed with a handheld dynamometer. Participants performed the YBT-UQ in the superolateral, medial, and inferolateral directions. The absolute isometric peak force (in Newtons) was normalized to body weight (in Newtons per kilogram) for each muscle test. For each YBT-UQ direction, the distance (in centimeters) was normalized for upper limb length (in percentage). A backward multiple linear regression analysis was used to determine the associations between variables. Results: The analysis revealed that the isometric strength of the lower trapezius (β = 26.82; 95% confidence interval, 21.24–32.40) is associated with inferolateral YBT-UQ performance (adjusted R2 = .706; P < .001). This factor explains 70% of the variability of the YBT-UQ in the inferolateral direction. Conclusions: Lower trapezius isometric strength is associated with inferolateral YBT-UQ performance of the dominant upper limb in amateur volleyball players. These findings could help in the development of more specific training programs and rehabilitation goals according to the performance of the athletes in the test.

Cardiomyopathies represent a group of diseases of the myocardium of the heart and include diseases both primarily of the cardiac muscle and systemic diseases leading to adverse effects on the heart muscle size, shape, and function. Traditionally cardiomyopathies were defined according to phenotypical appearance. Now, as our understanding of the pathophysiology of the different entities classified under each of the different phenotypes improves and our knowledge of the molecular and genetic basis for these entities progresses, the traditional classifications seem oversimplistic and do not reflect current understanding of this myriad of diseases and disease processes. Although our knowledge of the exact basis of many of the disease processes of cardiomyopathies is still in its infancy, it is important to have a classification system that has the ability to incorporate the coming tide of molecular and genetic information. This paper discusses how the traditional classification of cardiomyopathies based on morphology has evolved due to rapid advances in our understanding of the genetic and molecular basis for many of these clinical entities.

Review Current

The lower extremities of the human body are more commonly known as the human legs, incorporating: the foot, the lower or anatomical leg, the thigh and the hip or gluteal region.The human lower limb plays a simpler role than that of the upper limb. Whereas the arm allows interaction of the surrounding environment, the legs’ primary goals are support and to allow upright ambulation. Essentially, this means that reconstruction of the leg is less complex than that required in restoring functionality of the upper limb. In terms of reconstruction, the primary goals are based on the preservation of life and limb, and the restoration of form and function. This paper aims to review current and past thoughts on reconstruction of the lower limb, discussing in particular the options in terms of soft tissue coverage.This paper does not aim to review the emergency management of open fractures, or the therapy alternatives to chronic wounds or malignancies of the lower limb, but purely assess the requirements that should be reviewed on reconstructing a defect of the lower limb.A summary of flap options are considered, with literature support, in regard to donor and recipient region, particularly as flap coverage is regarded as the cornerstone of soft tissue coverage of the lower limb.
