Background. SIRT3 is one of the members of the Sirtuin deacetylase protein family which is linked to the longevity of human being and is used as an important therapeutic and diagnostic marker in illness and aging. Objectives. The aim of this study was studying the effect of continuous swimming training on some biomarkers of longevity in slowtwitch (SOL) and fast-twitch (EDL) muscles of adult m...

BACKGROUND Exercise has been found to either reduce or increase arterial stiffness. Land-based exercise modalities have been documented as effective physical therapies to decrease arterial stiffness. However, these land-based exercise modalities may not be suitable for overweight individuals, in terms of risks of joint injury. The purpose of this study was to determine the effects of 8-week swi...

PURPOSE The aim of this study was to analyse changes taking place within selected kinematic parameters of the swimming start, after completing a six-week plyometric training, assuming that the take-off power training improves its effectiveness. METHODS The experiment included nine male swimmers. In the pre-test the swimmers performed three starts focusing on the best performance. Next, a plyo...

After running training, which increased GLUT-4 protein content in rat skeletal muscle by <40% compared with control rats, the training effect on insulin-stimulated maximal glucose transport (insulin responsiveness) in skeletal muscle was short lived (24 h). A recent study reported that GLUT-4 protein content in rat epitrochlearis muscle increased dramatically ( approximately 2-fold) after swimm...

Competitive swimming events consist of different distances from 50m to 1500m. Since the exercise intensity and the relative importance of aerobic and anaerobic energy processes vary depending on the exercise time (and thus swimming distance), training regimen should be developed in accordance to time dependent metabolic profile. To understand the time dependent metabolic profile of arm stroke (...

Chronic swimming training and phytotherapeutic supplementation are assumed to alleviate oxidative damage, and support cell survival in the brain. The effect of forced, chronic swimming training, and enriched lab chow containing 1% (w/w) dried nettle (Urtica dioica) leaf were investigated for oxidative stress, inflammation and neurotrophic markers in Wistar rat brains. The rats were divided into...

1. The differentiation of myotomal muscles in the brook trout (Salvelinus fontinalis Mitchill) has been investigated using p-phenylene diamine stained semi-thin sections and cytochemical and quantitative determinations of enzyme activities. 2. Evidence is presented that the range of fibre size in white muscle represents stages in growth rather than distinct fibre types. 3. Electromyography show...

ABSTRACT Introduction: Synchronized swimming is a sport of artistic expression, skill, and physical fitness. Explosive, high-intensity movements rely mainly on the athlete’s good basal strength. Although China attaches great importance to training synchronized athletes, there no theoretical achievement in consolidating specific training. Objective: To analyze impact CORE strengthening athletes....
