Modular Technology

The authors of the article based on the systematization of data from scientific and methodological literature and analysis of training young biathletes practice developed a block-modular technology of complex strength training in the snow-free period, and also modified scandinavsky walking as a type of active activity to running exercises with Scandinavian sticks in order to develop strength endurance of the shoulder girdle muscles. Based on the conducted pedagogical experiment, the authors came to the conclusion that it is advisable to reduce cross-country training by 30-40% in the snow-free period due to the use of running exercises with Scandinavian sticks. The combination of block-modular complex strength training with Scandinavian sticks exercises allows us to most effectively increase the indicators of the shoulder girdle muscles power endurance and functional readiness of biathletes aged 13-16 years.

The Impact

Strength training is an important part of the preparation of competitive athletes. The subject of interest of the scientists connected of sports swimming was the level of strength ability of the competitors practising this sport and the influence of this ability on the final sports result. The purpose of this review is to describe and consider the impact of strength training of the shoulder muscles in sports swimming. A literature review was conducted in Embase, Medline PubMed, DOAJ, EBSCO and Google databases. Basic search terms are: training in sports swimming, strength tests, evaluation of muscle properties, rotation of the arm, strength measurement methods. Results: 235 results were found and 148 professional publications were selected and analysed. A thorough review of scientific publications indicates that strength parameters of the shoulder girdle muscles played a very important role on the sports performance of swimmers. The programmes combining swim training with 'on land' strength improvement or electrical stimulation are more effective than swim training alone. Significant fatigue of the rotator muscles can impair shoulder stability and result in injury. Increased strength in the internal rotation movement may result pathological conditions of the shoulder.

Duchenne's Muscular Dystrophy

AbstractMuscular dystrophies are a heterogeneous group of inherited diseases. The natural history of these disorders along with their management have changed mainly due to a better understanding of their pathophysiology, the evolution of standards of care, and new treatment options. Dystrophinopathies include both Duchenne's and Becker's muscular dystrophies, but in reality they are a spectrum of muscle diseases caused by mutations in the gene that encodes the protein dystrophin. Duchenne's muscular dystrophy is the most common form of inherited muscle disease of childhood. The current standards of care considerably prolong independent ambulation and survival. Several therapeutic options either aiming at substituting/correcting the primary protein defect or limiting the progression of the dystrophic process are currently being explored in clinical trials.Limb-girdle muscular dystrophies (LGMDs) are rare and heterogeneous conditions, characterized by weakness and wasting of the pelvic and shoulder girdle muscles. Originally classified into dominant and recessive, > 30 genetic forms of LGMDs are currently recognized. Further understanding of the pathogenic mechanisms of LGMD will help identifying novel therapeutic approaches that can be tested in clinical trials.

The goal of our study was to examine the muscle activity of the shoulder girdle after isokinetic fatigue, which may simulate muscle activities commonly occurring during specific sport-related activities in recreational overhead asymptomatic athletes. We hypothesized that exercise-induced fatigue, reported after isokinetic protocols, may cause a decrease in the median frequency (MF) of the upper trapezius (UT), infraspinatus (IS), and deltoid muscles. Twenty-four male overhead volleyball (n = 8), handball (n = 8), and tennis (n = 8) athletes participated in this study. All subjects were without shoulder injury history. The surface electromyography (SEMG) was collected on the right (dominant) side of the shoulder girdle muscles in the following order: UT, IS and anterior (DA), and posterior deltoideus (DP). The fatigue protocol consisted of three sets of 32 maximum isokinetic concentric contractions while performing shoulder internal and external rotation at an isokinetic speed of 120 o/s. The resultant difference in median frequency (ΔMF) values consistently dropped after the fatiguing tasks across all recorded muscles, in terms of the initial MF (MFINI = 65.1 ± 1.1 Hz) and final MF (MFFIN = 57.9 ± 0.9 Hz), and the main effect of time was significant (F(1,22) = 43.15, p < 0.001). MF values decreased mostly for IS (ΔMFIS = −9.9 ± 1.6 Hz) and DP (ΔMFPD = −9.5 ± 1.9 Hz) muscles, while DA and UT showed smaller changes (ΔMFDA = −6.9 ± 1.5 Hz) and (ΔMFUT = −3.2 ± 1.3 Hz). The results of our study show a meaningful contribution in determining increased fatigue of the shoulder girdle muscles during repeated isokinetic internal-external rotation protocols. We have also demonstrated a significant decrease in MF in all examined muscles, especially IS and DA.
