Blood metabolic response to a long-term wheelchair rugby training

Abstract

A voluntary participation in a long-term WR training program has several health promoting outcomes for individuals with chronic SCI. Among the most important are enhancement of the blood antioxidant defense capacity evidenced by lower MDA and higher EAP levels, as well as WR training-induced activation of BDNF signaling.

Sixty days of head-down tilt bed rest with or without artificial gravity do not affect the neuromuscular secretome

“…Additional artificial gravity to bed rest did not result in any change in BDNF serum concentrations. This corresponds with the observation that wheelchair rugby training did not induce an increase in BDNF in otherwise sedentary chronic cervical spinal cord injury participants [57] and suggests that exercise does not have an effect on BDNF serum levels during periods of disuse.…”

Comparison of Designated Coefficients and their Predictors in Functional Evaluation of Wheelchair Rugby Athletes

“…Previous studies have shown that long-term wheelchair rugby training elicits favorable changes in the lipid profile and antioxidant status ( Sadowska-Krępa et al, 2015 ). However, there were no statistically significant differences between the evaluated variables in the LP and HP groups.…”

“…Samples of heparinized blood were centrifuged for 10 min at 1.000 g at 4°C to separate plasma and erythrocytes, that were then washed three times with cold (4°C) saline and kept frozen at −80°C for further analysis. Activities of superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) glutathione reductase (GR), concentrations of reduced gluthatione (GSH), uric acid, glucose, insulin, total cholesterol (TC), HDL-cholesterol (HDL-C) and triglycerides (TG) were assessed as previously described ( Sadowska-Krępa et al, 2015 ).…”

“…The complex pathophysiology of spinal cord injury (SCI) involves two mechanisms of injury: the primary one which is due to initial mechanical damage, and the secondary mechanism which is related to vascular, cellular and biochemical events. As a consequence of the primary mechanism of SCI, many organs, including these of the cardiovascular (CV) system, cease to be controlled by the autonomic nervous system (ANS) ( Sadowska-Krępa et al, 2015 ). Response to physical activity fails to meet the needs of the body and typically results in low blood pressure (BP), what leads to reduced endurance and a decrease in sports performance.…”

Quality of Life and Associated Factors Among Male Wheelchair Handball Athletes

“…Regarding the origins of disability, we observed a significant QOL difference among participants in different classifications groups. For example, we observed a higher frequency of higher QOL among athletes with physical disabilities due to cerebral palsy (CP), a non-progressive disorder affecting the developing brain (Rosenbaum et al, 2007). As this neurodevelopmental disorder arises at birth or in the first years of a child's life, CP may place a different burden on these participants than might other origins of disability for other WH athletes.…”
