W pracy przeprowadzono badania związane z pomiarami biomechanicznymi pływaków. Opracowano metodykę prowadzenia pomiarów oraz przeprowadzono wstępne badania, w ramach których dokonano pomiaru czasów przepłynięcia dystansu 100m stylem klasycznym wraz z międzyczasami oraz pomiarów momentów sił mięśniowych w warunkach izokinetycznych na stanowisku Biodex. Wyniki porównano i określono zależności pomiędzy wynikami osiągniętymi na basenie i podczas pomiarów w laboratorium.

In these thesis did a review based on different literature sources about biomechanical research among sportsmen. After that an author did a measurement of muscle torques on a Biodex chair. The author summarized the results which the swimmers got on a 100 meters distance with the results that they got by using biomechanical devices. The comparison showed that the swimmers which got the better results have less muscle fatigue and achieve greater muscle torques for the bending and straightening of the knee.

Purpose: The main purpose of this study to analyze the coordination, propulsion and non-propulsion phases in the 100 meters breaststroke race. Methods: Twenty-seven male swimmers (15.7±1.98 years old) with the total body length (TBL) of 247.0±10.60 [cm] performed an all-out 100m breaststroke bout. The bouts were recorded with an underwater camera installed on a portable trolley. The swimming kinematic parameters, stroke rate (SR) and stroke length (SL), as well as the coordination indices based on propulsive or non-propulsive movement phases of the arms and legs were distinguished. Results: Swimming speed (V 100surface breast ) was associated with SL (R=0.41, p<0.05) and with TBL tending towards statistical significance (R=0.36, p<0.07), all relationships between the selected variables in the study were measured using partial correlations with controlled age. SL interplayed negatively with the limbs propulsive phase Overlap indicator (R=-0.46, p<0.05), but has no significant relationship to the non-propulsion Glide indicator. Conclusions: The propulsion in-sweep (AP3) phase of arms and their non-propulsion partial air recovery (ARair) phase interplayed with V 100surface breast (R=0.51, p<0.05 and 0.48 p<0.05) respectively, displaying the importance of proper execution of this phase (AP3) and in reducing the resistance recovery phases in consecutive ones.
