Unlabelled: The objective of this study was to evaluate the electromyographic activity of the muscles of the leg and spine associated with different types of shoes and barefoot, in the various plans of locomotion, in the situations before and after fatigue.
Methods: Is a cross-sectional study, which was used a sample of convenience with 15 young women, aged between 18 and 35 years, sedentary. The examined muscles were tibialis anterior, gastrocnemius medialis and lateralis and erector spinae. The muscular activity was assessed during locomotion on flat surface, up and down stairs and in an inclined surface. The shoes were a high-heeled, small heeled, tennis, slipper and barefoot.
Results: The results of electromyographic analysis showed that the muscles of the leg had greater electromyographic activity in the position of pre-fatigue of the lower limbs and erector spinae in the postfatigue of the lower limbs, in most of the conditions and situations.
Discussion: Adaptive conditions associated with regular use of high shoes, has been widely questioned in relation to the incidence of injuries.
Conclusion: In post-fatigue of the lower limbs, there was a decline in the activities of the muscles of the leg and increased recruitment of the erector muscles justified by the need for greater stability of the spine and pelvis during the locomotion of young women.

Background: Isokinetic dynamometry is a common tool for evaluating muscle function and is used across various disciplines. Technical advancements have shifted focus towards multi-joint exercises such as the leg press, offering insights into practical human movement dynamics. However, previous reproducibility studies have focused predominantly on single-joint exercises, warranting investigations into the reliability of multi-joint exercises.

Purpose: Blood lactate concentration is commonly used to assess metabolic demand and skeletal muscle training response. The objective of the pilot study was to investigate if a change in blood lactate was detectable in an anaerobically designed vocal demand task vocal capacity anaerobic task (VCAT) and determine if the developed vocal demand task may assess the anaerobic capacity of the voice musculature, like anaerobic power tests commonly used in applied exercise science.
Methods: A prospective repeated measures study quantified blood lactate concentration preVCAT and postVCAT in vocally healthy adults.

We sought to clarify the interface pressure (IP) and its variation by applying Biflex16, a calibrated bandage, to the lower leg. In Study I, 50 participants applied a bandage to the lower leg of a single subject in two ways: first, with 50% overlap, while the calibration rectangle became a square (Application 1), and then with 50% overlap without intentional stretch (Application 2) which served as a control. In Study II, another 51 participants applied the bandage to their lower leg via Application 1.

Hoffmann syndrome, a rare manifestation of hypothyroid myopathy in adults, is characterised by muscle weakness, stiffness and pseudohypertrophy. Here, we report the case of a middle-aged man who presented with progressive weakness in proximal muscles (in the form of difficulty in climbing stairs, rising from a seated position, combing hair and lifting objects) and leg swelling for 6 months. Physical examination revealed pseudohypertrophy of calf muscles with pronounced symmetric weakness in proximal upper and lower limbs.
