The main aim of our study was to determinate whether a repeated bout (RB) (vs. first bout [FB]) of sprint interval cycling exercise (SIE) is sufficient to mitigate SIE-induced psychological and physiological biomarker kinetics within 48 h after the exercise. Ten physically active men (age, 22.6 ± 5.2 years; VO2max, 44.3 ± 5.7 ml/kg/min) performed the FB of sprint interval cycling exercise (12 repeats of 5 s each) on one day and the RB 2 weeks later. The following parameters were (...) measured: motor performance (voluntary, electrically induced and isokinetic skeletal muscle contraction torque, and central activation ratio [CAR]); stress markers (BDNF, cortisol, norepinephrine, and epinephrine); inflammatory markers (IL-6, IL-10, and TNF-); metabolic markers (glucose and lactate); muscle and rectal temperature; cycling power output; and psychological perceptions. The average cycling power output and neuromuscular fatigue after exercise did not differ between the FB and RB. There were significant decreases in cortisol and BDNF concentration at 12 h (P < 0.05) and 24 h (P < 0.001) after the FB, respectively. The decrease in cortisol concentration observed 12 h after exercise was significantly greater after the RB (P < 0.05) than after the FB. The immune-metabolic response to the RB (vs. FB) SIE was suppressed and accompanied by lower psychological exertion. Most of the changes in psychological and physiological biomarkers in the FB and RB were closely related to the response kinetics of changes in BDNF concentration. (shrink)

Rural community organisations (RCOs) are part of a non-governmental organisations network, an effective tool for tackling local problems and reducing growing territorial exclusion. Despite their significance, it is not fully clear how many of these organisations exist in Lithuania. This is due to several reasons: the typology of settlements in the national law (more specifically, the definition of rural areas) no longer reflects the demographic reality, and the definitions contained in the sub-legislation are ‘manipulated’. In the context of the activities (...) of RCO, this is a flawed practice as it slows down the empowerment of the existing potential of organisations. The article presents the issue of the RCO network as well as addresses the problem of the typology of the settlement system itself. Adapting the research practice opens a scientific debate to launch a search for answers to emerging problems. (shrink)
