Footedness and Mounting—Short Review and Two Case Studies

Footedness is a personal quality like handedness. Footedness may be associated with moving ability during mounting, dismounting, and jumping movements. Occupational accidents have occurred during movement at different working levels, during the use of access and exit systems, and during the mounting of vehicles. Aging can also affect accident risk and body laterality. For example, falling accidents on stairs are common among the elderly. One reason for accidents may be that the structure of the access system or stair system is unsuitable for individual moving patterns depending partly on body laterality. Footedness and the way the feet are used may be contradictory to the demands of the moving situation, especially during uncommon or rapid situations. This contradiction may trigger disturbance during moving. The aims of this pilot study were (a) to review the literature briefly and (b) to describe the use of the dominant and nondominant foot by farmers and the elderly when mounting a tractor and stairs, respectively. The study also gives ideas for future studies based on both (a) and (b).     

Force-Velocity Characteristics of Individual Human Skeletal Muscles: TBCIat and TBCIong. Outline of the Method

The aim of the work is to outline a procedure of finding force-velocity (F–V) characteristics (F = f(V)) of individual skeletal muscles of the human locomotor system. The presentation is based on an example concerning extensors of the elbow joint: the lateral and long heads of triceps brachii (TBCIat and TBCIong). The experimental part of the procedure involves a natural movement of using the upper extremity to push an external object of variable, adjustable load, engaging both the elbow and shoulder joint.

Five men aged 23 took part in the experiment. Their task was to push the handle of a physical pendulum whose moment of inertia could be adjusted within the range of 58 kg m²-450 kg m², so as to give it maximum angular velocity. During each trial the movement of the trunk, of the upper extremity and of the pendulum was video recorded and the force applied with the hand to the handle of the pendulum was measured.

In order to find the F–V characteristics a simulation model SHOULDER was used, which is capable of solving the synergy problem for muscles of the arm and the shoulder girdle.

It was found that despite considerable dispersion of experimental points the respective regression lines revealed a clear tendency of decreasing muscle force for increased shortening velocity of the monoarticular head (TBCIat) and of increasing muscle force for increased lengthening velocity of the biarticular head (TBCIong) of the triceps brachii muscle.     

The Moderating Role of Hardiness and Social Support in the Relation Between Job Stressors and Well-Being. A Lesson From a Clerical Women Sample

The study concerns the moderating role of two variables—hardiness and social support—in the relation between job stressors and well-being. It was checked if there is a connection between hardiness and social support, and if these variables are directly related to the level of well-being. It was also hypothesized that hardiness and social support buffer the negative influence of stressors on well-being. The fact that social support and well-being are multidimensional variables was taken into account.

The cross-sectional study was conducted on a group of 200 women employed as office workers. The results showed that hardiness correlates with the indexes of emotional support as well as practical support coming from supervisors. The connection, however, was not strong. Hardiness and social support were directly connected with the level of well-being. Interaction of these two independent variables played a marginal role. As far as the buffering role of these variables was concerned, the results have shown that hardiness did not play a buffering role and social support did to a limited degree only.

The results of the study proved that it is justifiable to treat social support and well-being as multidimensional variables.
