本研究では、発達性協調運動障害(以下、DCD)のある幼児に、運動協応性を必要とする両手でのボール転がし課題を実施して、その練習段階における学習を検討した。DCDが疑われる幼児9名(DCD群)と統制群9名(CON群)とを抽出し、対象児には、2種類の練習課題の後、新奇なテスト課題を実施した。DCD群はCON群よりも低成績だったが、両群とも練習により成績は向上しており、特にDCD群の成績は大きく変動していた。DCDのある幼児は、新奇な課題には順応が容易ではなく、以前の練習による経験が想起されるまでに時間を要するが、練習によってある程度のパフォーマンスの向上を望めることが示唆された。

The purpose of this study was to report the supporting approach for the improvement of the athletic performance of a Paralympic swimmer. The subject was a gold medalist in the 50 m breast stroke event in the 2008 Beijing Paralympic Games, and was classified in SB3 according to a congenital limb deficit. Four synchronized under-water video cameras (60 fps and 1/1000s) were used to record the maximum 50 m breast stroke swimming motion. Three-dimensional coordinates of anatomical landmarks of the swimmer were obtained using DLT procedures. Filming and analysis were executed three times every two months. Video-imaged and motion analysis results were relayed back to the athlete and coach every time. Suggestions for the athletic performance improvement derived from the motion analysis were as follows: (1) increase stroke length and decrease stroke rate, (2) conform stroke motion in non-breath stroke to the motion in on-breath stroke, and (3) decrease drag force in recovery phase, and shorten stroke length of right arm in late in-sweep phase. The filming and supporting activities based on data acquisition and analysis were continued to the 2012 London Paralympic Games for improving the athletic performance so as to achieve the best results for athletes.

Purpose. To clarify relations between physical activity levels and activity of daily living (ADL) and quality of life (QOL) scales in elderly nursing home residents. Methods. Participants were ambulatory geriatric nursing home residents without dementia symptoms. Physical function (gait velocity and step length), ADL (Barthel Index), and QOL (Life Satisfaction Index A [LSIA] and Philadelphia Geriatric Center Morale Scale [PGC]) levels were measured. Physical activity level was assessed as activity energy expenditure and duration of physical activities (low and moderate intensities) calculated by accelerometer over 7 days. Intra-class correlation analysis was conducted to examine the consistency of each measurement results by the accelerometer. Variables on QOL scales were assessed by partial correlation coefficient analyses. Results. Seven subjects were recruited. Although a consistent significant relation was noted between activity energy expenditure and duration of low-intensity physical activity (under SMETs), no significant relation was seen between energy expenditure and duration of moderate-intensity physical activity (above 3 METs). LSIA was significantly correlated with gait velocity and step length. PGC was significantly correlated with energy expenditure and duration of low-intensity physical activity. Conclusions. Physical activity levels in geriatric nursing home residents could be quantitatively analyzed by accelerometer. Longer duration of low-intensity physical activity is important for the maintenance and improvement of QOL.
