Despite the high availability of surface electromyography (sEMG), it is not widely used for testing the effectiveness of exercises that activate intrinsic muscles of foot in people with hallux valgus. The aim of this study was to assess the effect of the toe-spread-out (TSO) exercise on the outcomes of sEMG recorded from the abductor hallucis muscle (AbdH). An additional objective was the assessment of nerve conduction in electroneurography. The study involved 21 patients with a diagnosed hallux valgus (research group A) and 20 people without the deformation (research group B) who performed a TSO exercise and were examined twice: before and after therapy. The statistical analysis showed significant differences in the third, most important phase of TSO. After the exercises, the frequency of motor units recruitment increased in both groups. There were no significant differences in electroneurography outcomes between the two examinations in both research groups. The TSO exercise helps in the better activation of the AbdH muscle and contributes to the recruitment of a larger number of motor units of this muscle. The TSO exercises did not cause changes in nerve conduction. The sEMG and ENG are good methods for assessing this exercise but a comprehensive assessment should include other tests as well.

Summary The soccer goalkeeper's reaction speed to stimulus is essential for the overall success rate of goalkeepers in soccer. Our research was aimed at finding out the impact of age and agility performance level on the length of the disjunctive reaction time of elite goalkeepers in Slovakia. The research group was comprised of 24 goalkeepers of two Slovak soccer clubs (in group A were elite players and in group B sub-elite players). To gain the research data, the disjunctive reaction time was measured using the Fitro Agility Check device. The acquired results were statistically evaluated using the Mann-Whitney U-Test and Cohen's “d”. The impact of age (n.s) and performance level (n.s) on the length of the disjunctive reaction time of goalkeepers was not statistically confirmed. However, the substantive and logical significance showed that the best goalkeepers achieved a considerably shorter time of disjunctive reaction time to the set stimulus (difference – 20 %).

We have recently carried out a study of spermiogenic differentiation in two geographically isolated populations of Aphanius dispar (freshwater teleost), with a view to ascertaining variation at the ultrastructural level. The sampling areas were the Jebel Al Akhdar in the north (Group A) and the Dhofar region (Group B) in the south. Specimens from each group were collected, the testes removed, fixed in Karnovsky solution, post fixed in OsO, en bloc stained with uranyl acetate and then routinely processed to Agar 100 resin, semi and ultrathin sections were prepared for study.
