The aim: The article examines the health-saving competencies of fitness technologies usage during physical education classes. Materials and methods: Experimental work was carried out in three stages, each of which was characterized by certain goals and objectives, corresponding forms and methods of research organization. To determine the formation of each of the studied components, we used complex of valid diagnostic techniques. Results: Implementation of the methodological system significantly influenced on general level of motivational, cognitive, activity and reflexive component formation, which significantly improved, compared with the students of control groups who studied under the traditional system. Evaluation of students’ competence in applying fitness technologies showed a high efficiency of the introduced methodological system. Conclusions: The introduced methodical system of fitness technologies application contributed to increase of the level of students’ preparedness by criteria of organizational, communicative, perceptual, speech abilities to fitness technologies, general cultural level, social activity and their involvement in healthy lifestyle. At the same time, the formation of competences in fitness technology usage contributed to the creation of new content of the main components of the methodological system.

The kinetic energy dependence of ions trapped in a radio-frequency (RF) hexapole ion trap has been calculated as a function of space charge, mean free path, mass, RF potential and charge. The average kinetic energy of the ions was found to increase with increasing space charge, mean free path and the ion charge state. For a trapped ion in a given coulombic field, the mass of the ion and the amplitude of the applied RF potential did not affect the average kinetic energy. The consequences for multipole-storage-assisted dissociation (MSAD), in which ions are accumulated for prolonged periods of time in the multipole ion trap of an electrospray ion source, are discussed. As a result of radial stratification inside the ion trap, MSAD can lead to the preferential excitation of ions with larger m/z values. Such discrimination would have negative consequences for the detection of labile non-covalent adducts, which are normally detected at higher m/z values than their constituent species.
