Quality of life is an ambiguous concept with a medical, sociological and economic dimension, as well as psychological, the most subjective one. Physical activity is considered one of the most important elements of a healthy lifestyle and a factor that determines the physical and mental health of an individual. The article presents the issue of physical activity in the aspect of quality of life management. It was found that respondents notice a very large relationship between sport and quality of life. The authors showed that it is very important in the quality of life management aspect not only to promote physical culture, but also to develop the habit of practicing it.

Purpose: The aim of this study was to determine how minimalist running shoes (MRS), conventional running shoes (CRS) and the dominance of lower limbs influence the running gait. Methods: Trained recreational runners (N = 13) who have been engaged in regulary running for more than one year were participants in this study. They were experienced with using MRS and CRS for more than half year and they used both types of shoes. An in-shoe pressure measuring system (Pedar-X®, Novel, Munich, Germany) was used to monitor plantar pressure and vertical force and the temporal parameters when running in MRS and CRS during the stance phase, the swing phase and over one stride. Results: Running in CRS significantly prolonged stance, swing and stride phases by 2–11% compared to MRS. In contrast, when running in MRS significantly larger values of maximum pressure (9–14%) and maximum vertical force (3–7%) than in CRS were found. Conclusions: For this reason, running in MRS could be recommended to recreational runners only with care. The effect of limb dominance on temporal characteristics was detected when running in CRS. Significantly longer stance phase for dominant limb is associated with a shorter swing. The kinematics variables were significantly higher for dominant limb than for non-dominat limb when running in MRS and CRS (by 12–23%).

This paper presents an experimental and theoretical implementation of the influence of the run-walk treatment in the presence of an electro-magnetic field on energy burn increments in the human body, its metabolism, and finally on the decrements of the human body weight. The experimental research presented in this paper was performed using the following devices: a magnetic induction field produced by a new Polish MT-24 Apparatus, a new German Magcell Arthro magneto electronic device, and a Segmental Body Composition Analyzer Tanita MC 780MA. The author's experience was gained in German research institutes, and practical results were confirmed after measurements and information from students and patients. Up to now, theoretical solutions have not been considered. The theoretical and numerical model presented was implemented by using the Mathcad 15 Professional Program. The main conclusion obtained in this paper can be formulated in the following sentence: The run-walk training implemented by an electro-magnetic magnetic field using tight sportswear leads to the increments of the dynamic viscosity of synovial fluid, changes the internal energy contained in the human body, increases the muscle weight, and the percentage of water in the human body; therefore, it accelerates the slimming process connected with the body weight decrements.

The purpose of the study was to investigate how novice runners adjust their lower extremities in heel-toe running while they wear dress shoes and running shoes. Ten novice male runners repeatedly ran across a force plate at 4 m/s in each type of shoes. Joint kinematics and kinetics, vertical ground reaction force, and utilized coefficient of friction during the stance phase were quantified. The results obtained showed no differences in impact peaks, stance time, stride length and joint kinematics. However, dorsiflexion moment was significantly greater with dress shoes (407 Nm) compared to that with running shoes (304 Nm; p < 0.05). Compared to the runners in running shoes (0.23), the runners in dress shoes (0.20) achieved a significantly lower utilized coefficient of friction ( p < 0.05). When running in dress shoes, novice runners tended to use better a dorsiflexion moment than when running in running shoes. This adaptation appears to minimize the chances of slipping at the moment of heel strike.

The work presents analyze of vertical acceleration curve of the body mass center (VACM characteristic) obtained by eleven athletes during on treadmill running with gradual rise velocity. The measurements are made by uniaxial accelerometer placed in loins part of trunk near the center of body mass. The chosen value of characteristics was calculated for every single run with applied velocity of treadmill The velocity of treadmill of every run was significantly correlated to mean values of VACM characteristics calculated for all subjects. For every athletes analyzed mean values of characteristics calculated separately for left and right steps were significantly different.
