The Effect of (Crossfit) Exercises in some types of endurance, pulse, and Lactic acid concentration ratio by students.

Abstract

The aim of the research is preparing crossfit exercises for the sample of research, and identifying the differences between (pre and post) tests in investigated variables by experimental and controlled groups of research, the researchers used experimental curriculum, the community of the research has been selected by intentional way from first year students of Basic Physical Education department, Physical Education and Sport Sciences / Sulaimani University for Academic year (2019-2020) they have divided into (3) groups ( A,B,C) they are (59) students, as for the sample of the research they were randomly selected represented by group (A) they are (21) students by that the number of sample became (16) students (%27.11) of all community, the sample divided randomly into two groups experimental and controlled by lottery way (8) students for each group, and duration of training curriculum (6) weeks (3) training units per week as for total training units became (18) units the researches reached the following conclusion the importance of using crossfit exercises in giving them adaption and raising the level of fitness of individuals training curriculum by crossfit way which carried out by experimental group occurred significant progress by investigated variables and represented by (Endurance Speed, Endurance Strength for (legs, arms, and core), the pulse effort, lactic acid)
