One-dimensional V-Scope analysis of habituation to simulated cross-country skiing

Abstract

Responses to simulated cross-country skiing were measured using the V-Scope, a new telemetric ultrasound motion monitor. Ten young male adults performed a total of 45 minutes of distributed practice on a Nordic-Track ski simulator. Over a period of three 15-minute sessions cadence and velocity were unchanged. Step and stride lengths decreased significantly (p < 0.05) after the first 15-minute session and then remained unchanged. There were no left-right limb differences across all sessions indicating a normal gait. Response variability in velocity, step lengths and stride length was dramatically reduced after the first exposure period. This study demonstrates that the V-Scope system is a useful motion analysing device and, on the basis of the data presented in this preliminary investigation, at least two 15-minute habituation sessions are required for initial habituation to simulated cross-country skiing.

Video analysis of gait for diagnosing movement disorders

“…Quantitative gait analysis is an important clinical tool for quantifying normal and pathological patterns of locomotion and has been shown to be useful for prescription of treatment as well as in the evaluation of the results of such treatment. 2,10,28 Apart from being used in the field of medicine, quantitative gait analysis is also widely used in other areas, such as sports 6 and research of work-related occupational hazards. 32 Current quantitative video analysis techniques require patients to be video taped while wearing joint markers in a highly structured laboratory environment with extensive setup procedures.…”
