Functional near-infrared spectroscopy (fNIRS) serves as a promising tool to examine hemodynamic response alterations in a sports-scientific context. The present study aimed to investigate how brain activity within the human motor system changes its processing in dependency of different barbell load conditions while executing a barbell squat (BS). Additionally, we used different fNIRS probe conf...

We read with great interest the article of Athanassiadi et al. [1] ‘Muscle-sparing versus posterolateral thoracotomy: a prospective study’ which elegantly compares the two approaches for thoracic surgery. Based on the results of their prospective study Athanassiadi et al. concluded that the rates of occurrence of acute and chronic pain and morbidity are equivalent after lateral muscle-sparing t...

The purpose of the current study was two-fold: (1) To examine the variation in velocity and power with increasing intensity in the back squat among subjects; and (2) To explore individual subject characteristics as possible explanations for variations of velocity in the back squat. Fourteen recreationally trained male subjects with experience in the back squat agreed to participate in the study...

This study examined the effects of two equal-volume resistance-training protocols upon strength, body composition and salivary hormones in male rugby union players. Using a crossover design, 24 male rugby players completed a 4-week full-body (FB) and split-body (SB) training protocol of equal volume during the competitive season. One repetition maximum (1RM) strength, body composition via skinf...

To investigate the effect of heavy resistance exercise on IGF-1 system, 19 healthy trained men and 15 healthy untrained men volunteered to participate in this study. The subjects were randomly divided into experimental and control groups. Subjects of experimental groups were forced to perform a heavy resistance exercise with the intensity of 70-80% of 1RM in selected movements. The blood sample...

this study aimed to investigate the effects of different doses of sulfadiazine on embryonic chicken pectoral muscles. in total, 100 fertile eggs were obtained and divided into five groups of control (no injection) and sulfadiazine injection at doses of 2, 10, 30, and 70 mg/kg. after hatching, pectoral muscle tissues were harvested from the newly hatched chickens for histopathological examinatio...

BACKGROUND Cytokines play an important role in modulating the muscle's metabolic and immunological responses to exercise. OBJECTIVES In the present study, we investigated changes in the serum levels of Interleukin (IL)-15 as well as tumor necrosis factor (TNF)-α and high sensitivity C-reactive protein (hs-CRP), as markers of inflammation, in athlete and non-athlete young men following eccentr...

BACKGROUND Muscle power diminishes with increasing age and inactivity. The capacity for older adults to increase muscle power with resistance exercise has not been examined; therefore, we examined the influence of progressive resistance training (PRT) on muscle power output in 17 men and women aged 56-66 years, and compared their responses to 15 men and women aged 21-30 years. METHODS All sub...

Objective: Standard compression stockings are used to create elastic pressure in correcting and maintaining the hemodynamics of deep vein thrombosis (DVT) and prevent limb swelling in patients with DVT. This study aimed to compare the effect of aerobic exercise with lower extremity elastic pressure on some hematological features of obese patients with DVT. Materials and Methods: For this purpo...
