The objective of the study reported in this paper involved identifying the fencing attack (flèche versus lunge) that provides greater effectiveness in a real competition. Two hypotheses are presented in the study. The first hypothesis involves the greater effectiveness of the flèche with regard to bioelectric muscular tension, and the second hypothesis involves the reduction of movement time of the flèche. Therefore, analyses were conducted by the application of EMG (electromyography) signal, ground reaction forces, and parameters representing sensorimotor responses (RT—reaction time and MT—movement time). This study included six world-leading female épée fencers (mean age: 24.6 ± 6.2 years). Throughout the procedure, the subjects performed flèche and lunge touches at the command of the coach based on visual stimuli. The experimental results indicated the greater effectiveness of the flèche compared with the lunge with regard to increases in EMG values (p = 0.027) in the lateral and medial gastrocnemius muscles and decreases in the duration of the movement phase (p = 0.049) and vertical force of the rear leg (p = 0.028). In conclusion, higher levels of EMG and ground reaction forces were generated during the flèche compared with the lunge, which promotes an improvement in the explosive force and contributes to a reduction in the movement phase of the entire offensive action.

Background. The function of the central nervous system in adolescents reflects the complex influence of climatic and social conditions, as well as morphofunctional lability characteristic of puberty. Studying the functional state of the central nervous system in adolescents living at high latitudes is important for forming a region-dependent norm of the functional state of the body. Aim. The paper aims to reveal the features of sensorimotor integration as an indicator of the functional state of the central nervous system in 11–14-year-old students living in the North. Materials and methods. 88 schoolchildren from Surgut (46 males and 42 females) aged 11–12 years (1 group, n = 33) and 13–14 years (2 group, n = 55) were examined. Psychophysiological testing was carried out with the help of the NS-Psychotest hardware and software (Neurosoft, Ivanovo). The following methods were used: simple visual and motor reaction, complex visual and motor reaction – choice reaction. Mathematical and statistical processing was carried out in Microsoft Excel and Statistica 10.0. Results. Sex-related differences in neurodynamic data were revealed: average parameters of boys of both groups in comparison with girls are characteristic of a more active and mobile central nervous system. The functional state of the central nervous system in males is higher than that of females in both age groups, though, sensorimotor responses of females are more stable. Age-related improvements in sensorimotor integration were noted due to improved cerebral processing of sensory information by reducing latency time of sensorimotor responses. In males, depending on age, there was a tendency to negative changes in the functional state of the central nervous system. Conclusions. The results obtained describe the average level of activation and a high level of functional mobility of nervous processes in all adolescents. The average level of the functional state of the central nervous system reflects the optimal functional capabilities of the participants, which is the basis for effective psychophysiological adaptation to living conditions and educational activities.

Sensorimotor Responses

The drastic increase in hallucinogenic compounds in illicit drug markets of new psychoactive substances (NPS) is a worldwide threat. Among these, 2, 5-dimetoxy-4-bromo-amphetamine (DOB) and paramethoxyamphetamine (PMA; marketed as “ecstasy”) are frequently purchased on the dark web and consumed for recreational purposes during rave/dance parties. In fact, these two substances seem to induce the same effects as MDMA, which could be due to their structural similarities. According to users, DOB and PMA share the same euphoric effects: increasing of the mental state, increasing sociability and empathy. Users also experienced loss of memory, temporal distortion, and paranoia following the repetition of the same thought. The aim of this study was to investigate the effect of the acute systemic administration of DOB and PMA (0.01–30 mg/kg; i.p.) on motor, sensorimotor (visual, acoustic, and tactile), and startle/PPI responses in CD-1 male mice. Moreover, the pro-psychedelic effect of DOB (0.075–2 mg/kg) and PMA (0.0005–0.5 mg/kg) was investigated by using zebrafish as a model. DOB and PMA administration affected spontaneous locomotion and impaired behaviors and startle/PPI responses in mice. In addition, the two compounds promoted hallucinatory states in zebrafish by reducing the hallucinatory score and swimming activity in hallucinogen-like states.
