چکیده

Abstract In Paralympic cross-country sit skiing, athlete classification is performed by an expert panel, so it may be affected subjectivity. An evidence-based required, in which objective measures of impairment must identified. The purposes this study were: (i) to evaluate the reliability 5 trunk strength and 18 control developed for classification; (ii) rank measures, according largest effects on performance. Using a new testing device, 14 elite sit-skiers two upright seated press tests one simulated poling test strength. They were also subjected unpredictable balance perturbations measure control. Tests repeated separate days test–retest was evaluated. A cluster analysis run correlation evaluated, including all identify that contributed most clustering participants. Intraclass correlations coefficients (ICC) 0.71 < ICC 0.98 0.83 0.99 perturbations, respectively. Cluster identified three clusters with relevance measures. For strength, peak anterior pushing force without backrest (effect size = 0.77) ratio 0.72) significant. range motion forward 0.81) backward 0.75) contributed. High (− 0.76 r − 0.53) found between protocol, show promising results assessing empower classification.

Kinematics of sprint cross-country skiing

The purpose of our study was to characterise the diagonal stride locomotion during a new short sprint race in cross-country skiing. Thirty male cross-country skiers were sagittaly filmed on an uphill portion of the 1.2-km classic race of the world cup (2004) using a digital camera. The main body joints, skis and poles were digitised frame by frame. Results indicated higher SV and SR for similar...
