Features of Stroke Volume Changes among Wheelchair Basketball-Players During Muscular Load Performance

Abstract
ABSTRACT The reaction of the stroke volume among disabled athletes was studied in order to perform a standardized muscular stress and the peculiarities of its recovery after the load completion. The analysis of the stroke volume was carried out in two stages. During the first phase SV indicators at rest were examined among disabled athletes alone. During the second stage disabled athletes performed muscle load in the form of shuttling acceleration during one minute along a basketball court perimeter. Then the features of stroke volume recovery parameters were analyzed. It was found that during the annual cycle of muscle training the values of stroke volume among wheelchair basketballplayers do not change uniformly. The lowest SV values among disabled athletes were registered during the preparatory period, and the highest SV values were registered during the competitive period. It was found that the reaction of stroke volume for muscle load performance and SV recovery time after muscular exercise completion depends on the level of fitness. The higher the level of fitness among wheelchair basketball-players is the shorter the recovery period of stroke volume parameters. The highest SV response for muscular load performance and simultaneously a rapid recovery of stroke volume after the completion of loading is observed during a competitive period. The lowest SV response on muscular load performance and a longer stroke volume recovery is observed during the preparatory period.
