Abstract EN

The research significance lies in laying down correct scientific foundations when choosing exercises according to the physiological aspect that depends on the critical ability associated with the oxygen deficit and the successful and effective training methods that make a serious contribution to the development of achievement by running short distances through the development of physical and physiological capabilities.

Physiological exercises assist the critical ability to reach the goal that the researcher intends to reach to contribute to the development of the level of achievement of these runners.

The research aims to: 1.Preparing critical endurance exercises in developing some physical abilities, lactic acid concentration and heart rate for short-distance runners.

2.Identifying the effect of critical endurance exercises in developing some physical abilities, lactic acid concentration and heart rate for short-distance runners.

The sample included short-distance runners for the (Peshmerga Sports Club) and the homogeneity and parity of the sample were conducted, pre and posttests and reconnaissance experiments were conducted.

Critical ability exercises were placed in the main section of the coach’s training units.

In light of the tests and measurements, a set of conclusions and recommendations were reached : The most important conclusions were : Critical power exercises are important and essential for the development of some physical abilities, lactic acid concentration and heart rate for short-distance runners.

The researcher recommended Adopting critical ability exercises in the training program because they are important and essential for the development of some physical abilities, lactic acid concentration and heart rate for short-distance runners.
