The effect of physical abilities material, Vo2max index, and achievement of 400-meter freestyle youth

The aim of the research is to prepare special skill physical exercises using resistances such as swimming pockets and drag pockets that are the central axis of the body, with the aim of developing the special physical abilities of 400 m swimmers (such as special speed, special endurance, strength endurance and endurance performance within the competition time). The talent for swimming in Baghdad, and the special tests were determined (swimming 25 m from the start, swimming 50 m from stability, swimming 450 m, the RAST test (fatigue index) and the indirect Vo2max index test), and pre-tests were conducted, and resistance exercises were applied for a period of time. (8) weeks, at a rate of two units per week, after which the post-tests were conducted, and the results of the research showed clear superiority of the experimental group members in all special physical abilities and the development of fatigue index and VO2 max capacity index.
