Zeroing of six-component handrim dynamometer for biomechanical studies of manual wheelchair locomotion.

A six-component handrim dynamometer (HRD) is a dynamometer that rotates around the wheel axle during measurements. For this kind of dynamometer, static zero level calibration is insufficient because the proportion of the forces (i.e.

The effect of feet position on orthostatic posture in a female sample group.

Until now, the feet position effect on orthostatic posture has been investigated only in male or mixed sample groups. However, literature reports gender differences on orthostatic equilibrium. In order to study the effect of feet position on females and to complete the previous works, we tested a homogenous female sample group with 16 feet positions.

The 5 min running field test: test and retest reliability on trained men and women.

The repeatability of the maximal aerobic velocity ( v(amax)) estimated using the 5 min running field test (5(RFT)) has been examined in an heterogeneous population of 132 subjects distributed in five groups considering their sporting activities, their competition levels and their physical fitness levels: among them were national and local runners, rugby players, and multi-sport women and men. To establish the test and retest reliability, all the subjects took part in the 5(RFT) twice within 3 weeks. After the normality of distributions had been assessed using a Kolmogorov-Smirnov's test, a Student's paired t-test showed no difference between the two trials in all groups except that of the national runners.
