Bandiniu serija DM ir D1 istyrus ultragarso impulso greicio tyrimo metodu nustatyta, kad i Dysnos radimvietes moli pridejus 20 % MVCF atlieku, ultragarso impulso greicio verte padideja nuo 3338 m/s iki 4043 m/s.
Rentgenografiniais tyrimo metodais istirti bandiniai, kuriuose naudota liesinanciu priedu--20 % MVCF atlieku (sudetis D1) ir 20 % smelio (sudetis D2).

There were significant decreases in Pt, P20 and P100, as well as in P20/P100 (p < 0.05, compared with the value immediately after SSE) at 60 min after SSE, but changes in MVCF or height of DJ were not significant (Figure 1, 2 and 3).
We have established, that there was a significant relationship between decrease in height of DJs and MVCF at 24 h and 48 h after SSE on the one hand, and muscle soreness (r = 0.72-0.94) and CK (r = -0.6-0.7) on the other hand.
Among the more detailed and interesting findings of this study the following might be mentioned: a) electrically evoked muscle force during SSE decreased significantly more than voluntary performance (height of DJs and MVCF); b) at the beginning of exercise (after 10 DJs) Pt, P20 and P100 changed significantly more than during the second part of SSE (at low frequency stimulation in particular); c) both during and after SSE MVCF decreased more significantly than height of DJ; d) there was a significant increase in Pt, P20 and P100 from 8 h to 48 h after SSE, whereas height of DJ, as well as MVCF, decreased significantly; f) the secondary decrease in height of DJ as well as MVCF significantly correlated with muscle soreness within 24-48 h.
After performing SSE indirect symptoms of muscle damage manifested themselves within 24 h -72 h after the load: the rise of muscle soreness (Figure 5) and the increased CK activity (Figure 6), prolonged impairment of neuromuscular performance (MVCF and height of DJ) (Figue 1), as well as the muscle force evoked by low and high electrostimulation frequencies (Figure 1).
Since after the exercise bringing about muscle damage the muscles are subjected to processes that, undoubtedly, should call forth decrease in MVCF we supposed that, likewise in the case with MVCF and height of DJ, there should also be a decrease in the force evoked by all stimulation frequencies during recovery after SSE.
The results of our study indicated that SSE affected more significantly stretch-shortening cycle performance (height of DJ) than MVCF (Figure 1).
We have established, that there is a significant correlation between decrease in height of DJ and MVCF at 24 h and 48 h after SSE on the one hand and muscle soreness and CK on the other hand.
