“…By assessing the maximal pronation behavior formed by the subtalar joint, through the 2-point method (5) , no significant differences were found between assessed individuals' right and left foot, in both genders. The same result was found by Wit, Clercq and Lenoir (9) where similar behaviors on maximal pronation values were found between assessed individuals' right and left foot.…”

“…On the subsequent week, after determining submaximal running speeds, a running-saving test was prepared, in which sample participants had to run during five (5) minutes within their respective gender speeds (11 and 13 km.h-1 for women, and 14 and 16 km.h-1 for men), bringing up to a total of 10 minutes of running for each individual. During the running-saving test, a tape was recorded at 120 Hz, in a frontal plane, behind the runner (Figures 2 and 3).…”

SUMMARYThe objective was to describe the behavior of the maximum pronation (MP), of the maximum pronation speed (PS) and of the linear crossover (LC) of the right and left feet of 23 distance runners during treadmill running, at speeds ranging from 11 to 13 km . h -1 for female athletes and from 14 to 16 km . h -1 for male athletes, related to an average of 70% -75% of the maximumComparison of the subtalar joint angle during submaximal running speeds aerobic power (VO 2max ). The statistical analysis (Student's T-Test for dependent and independent samples, p<0.05) showed that, by increasing submaximal running power, there was a significant increase on MP, and by increasing running linear speed, the PS was significantly higher. Regarding LC, we believe that this is biased by the running technique used by each runner.

“…Biomechanical studies of sport shoes have in general focused on kinematic (Bates et al, 1978;Stacoþ and Kaelin, 1983;Ferrandis et al, 1994) and kinetic (Frederick et al, 1984;Cook et al, 1985;Gheluwe and Deporte, 1992) variables, which aþ ect performance and injury in all sports. Most used force plates or cinematography, as these allow the variables of interest to be recorded objectively and reliably.…”

Subjective tests based on information gathered using 'discomfort questionnaires' have been used widely in ergonomics. In this study, we used a similar method to examine the discomfort associated with the footwear worn in tennis matches. A sample of 146 tennis players from a population of approximately 4000 completed the questionnaire. We performed a descriptive analysis of the study variables. The associations between discomfort and pain and between discomfort and design errors were evaluated using cross-tabulation and chi-squared tests. We found that 9% of players considered their footwear to be uncomfortable, 23% considered it to be acceptable and 68% regarded it as comfortable. Six design errors were identified and five body areas were reported as experiencing discomfort due to the footwear. Factor analysis identified four factors related to discomfort and six design errors. Subsequent correlation analysis identified several relationships among these factors. There was a strong correlation (r = 0.187, P = 0.022) between plantar discomfort and incorrect arch support.

Within the sport shoe area torsion is described as the twisting and decoupling of the rear-, mid- and forefoot along the longitudinal axis of the foot. Studies have shown that running shoes restrict the torsion of the foot and thus they increase the pronation of the foot. Based on the findings, it is recommended to design running shoes, which allow the natural freedom of movement of the foot. The market introduction of the first torsion concept through adidas(R) took place in 1989. Independently of the first market introduction, only one epidemiological study was conducted in the running shoe area. The study should investigate the occurrence of Achilles tendon problems of the athletes running in the new "adidas Torsion(R) shoes". However, further studies quantifying the optimal region of torsionability concerning the reduction of injury incidence are still missing. Newer studies reveal that the criterion torsion only plays a secondary roll regarding the buying decision. Moreover, athletes are not able to perceive torsionability as a discrete functional parameter. It is to register, that several workgroups are dealing intensively with the detailed analysis of the foot movement based on kinematic multi-segment-models. However, scientific as well as popular scientific contributions display that the original idea of the torsion concept is still not completely understood. Hence, the "inverse" characteristic is postulated. The present literature review leads to the deduction that the functional characteristics of the torsion concept are not fully implemented within the running shoe area. This implies the necessity of scientific studies, which investigate the relevance of a functional torsion concept regarding injury prevention based on basic and applied research. Besides, biomechanical studies should analyse systematically the mechanism and the effects of torsion relevant technologies and systems.
