The development of a special sequence physical training model to increase speed, limb power, reactive agility and endurance in youth football performance

The aim of this study was to develop a special sequential physical training model to increase speed, leg power, reactive agility and endurance in youth football performance. in detail the objectives of this research 1). to develop a special sequential physical training model to form speed, reactive agility, power and endurance simultaneously. 2). To test the feasibility of the drill training model to increase speed, reactive agility, power and endurance simultaneously. 3). To test the effectiveness of this drill training model, it aims to increase speed, reactive agility, power and endurance simultaneously.The research method used in the study is research & development (R&D), Brog & Gall. using five steps without reducing their meaning (1) first assessment and information gathering (2) Forming the first product (3) Forming a Hypothetical product (4) Effectiveness testing (5) Dissemination. The research subjects for assessment were 3 academic experts and 4 trainers with a minimum C AFC License. In the field trial (feasibility test) 4 teenage soccer athletes were involved. For the effectiveness test, 30 soccer athletes were involved. The data collection technique for preparing a draft special physical training model uses a narrative literature review technique. The steps used to collect expert test data are using the Delphi technique. The steps to collect product effectiveness test data use a pre-experimental research design using a time series design, with a MANOVA test to find out whether it is effective in improving physical health simultaneously.The results of this study show that (1) this training model product can improve physical fitness simultaneously, (2) this training model is feasible, secure, and safe to use at improving football physicality simultaneously and (3) this training model is effective in improving physical abilities simultaneously has a significance value of 0.000
