EFFECT OF ASSISTED TRAINING ON THE SPECIAL RUNNING PREPARATION OF JUNIOR SPRINTERS FOR 100 AND 200 m

Aim. To test the effect of the assisted training tools on the most important indicators affecting speed development and the results in 100 and 200 min junior sprinters. Particular tasks were chosen to test the effect of assisted training on the development of speed, maximum speed, and speed endurance. Materials and methods. The study included a group of 8 junior athletes and lasted seven weeks (the pre-competition mesocycle – 4 weeks; competition mesocycle – 3 weeks). The study focused on the assisted training tools having crucial importance for the results in 100 and 200 m. The effect of these tools on the development of speed, sprint, and speed endurance was tested by establishing the correlations between them. Results. The study revealed that using the 30 m series with assisted training promotedthe maximum speed and start acceleration. There was also a strong correlation between 30 m assisted speed and the result in 100 m, which indicated that this training tool improved both the starting acceleration and maximum speed deve­lopment. Also, it was found out that the 200 m result depended on 30 m AST run and the 100 m time. Conclusion. The results showed that using assisted training tools promoted speed deve­lopment by the improvement of the nervous and muscular capacity in young sprinters.

Whole-body Vibration Training as a Supportive Therapy During Allogeneic Haematopoietic Stem Cell Transplantation – A Randomised Controlled Trial

Effects of whole-body vibration (WBV) training in patients undergoing allogeneic haematopoietic stem cell transplantation (HSCT) remain unknown. We examined whether additional WBV training during hospitalisation may stabilise the physical capacity of patients undergoing allogeneic HSCT, improve health-related quality of life (HRQOL) and fatigue status of these patients. In this randomised controlled trial, 26 subjects were randomly allocated 1:1 in an intervention group (INT; n=13) or a control group (CON; n=13). Patients in the CON received conventional physical therapy and patients in the INT completed further WBV training every other day. Isokinetic measurement of the muscular capacity of the lower extremities, functional endurance capacity and HRQOL were evaluated before and after the intervention period. No unwanted side effects were observed. We found a significant positive effect of the intervention on the maximum relative peak torque in extension in the INT compared to the CON (p=0.019) and patients in the INT experienced less pain (p=0.05). WBV training can be successfully implemented as a supportive therapy for patients undergoing allogeneic HSCT. Furthermore, WBV training represents a safe and effective option in the maintenance of muscular capacity of the musculature of the lower extremities and may contribute to pain release.
