The context of the COVID-19 pandemic has caused educational institutions and sports clubs to change their management strategy. Due to the modernization of computer technology, physical education and sports (PES) teachers decided to include this technology in their teaching activity to help students and athletes to acquire PES-specific transversal skills and digital skills, and also to increase the attractiveness of the lessons. The present research aims at assessing the challenges and opportunities of technology and adopting an Agile Management style to improve the teaching, learning, and practice of PES. Therefore, a survey was conducted on PES teachers and trainers, as they have a clear perspective on the field and their views are therefore very important and relevant to our study, even if they do not have solutions for all the challenges facing them. They were asked to share their professional opinions regarding the implementation of digital methods and applications on the sportive results of performance sportsmen, athletes, and students. The survey, conducted on 144 respondents, contained mostly multiple-choice questions rated on a Likert scale and open-ended questions allowing respondents to offer solutions and express their opinion freely. This article demonstrates the positive influence of Agile Management in the choice and implementation of technology dedicated to PES.

Problem: Puberty age is considered the age of the first performances. Due to the mobility of cortical nerve processes and their functional ability, the rapid alternation of excitation and inhibition occurs in the motor areas of the cortex, which ensures synchronised contraction and relaxation of the muscle groups with contradicting actions, the right responses to excitations. So, physical training must be adapted to different age categories applying methods and means proper for these categories. Purpose: The research purpose is to optimise the training process of volleyball players in order to improve specific and general resistance. Premises: By using methods, techniques and specific means adapted to particularities of junior II players, the intended goals will be accomplished and consequently the quality of motor resistance specific to volleyball game will be improved. Research methods: bibliographic documentation; observation; motor testing; statistical and mathematical method; graphical method. Discussion and conclusions: By the end of this period, after the age of 15, special attention can be paid to the development of general resistance and specific speed resistance, based on the individualised training for settersspeed resistance, and for spikers -jump resistance. Specific training is done relying on general training. In the volleyball game, for each training period, complex methods have also to be set. Their percentage depends on the training period, players' particularities, main goals, etc. The selected ways for accomplishing the goals have been efficient, well dosed, which is highlighted by the progress obtained and the quality of executing the technical procedures.
