Hockey for the 2021/2022 training season. , and their number is (25) players, and the researcher used (8) players from the same research community and outside the basic research sample as an exploratory sample to verify the scientific transactions, and they represent the motor abilities variables (muscular strength - speed - muscular skin - respiratory periodic skin - neuromuscular compatibility - Flexibility) as represented by aerobic fitness variables (resting pulse - pulse after exertion - oxygen pulse - vital capacity - maximum oxygen consumption cooper test run or walk 12 minutes) The most important results indicated that individual CrossFit exercises positively affect the improvement of motor abilities represented in the muscular strength of the arms, muscular strength of the legs, speed, muscular skin, respiratory periodic skin, neuromuscular compatibility, and flexibility for hockey players, the research sample with rates ranging between (-4.72%) : 32.64%), and individual CrossFit exercises positively affect the improvement of aerobic fitness represented in (resting pulse - pulse after exertion - oxygen pulse - vital capacity - maximum oxygen consumption) for hockey players in the research sample at rates ranging between (-3.24%: 3.49) %). In light of the objectives of the research and its conclusions, the researcher recommended the use of CrossFit exercises in an individual style, especially in the emergency conditions of the spread of the Covid 19 virus and its new variants for hockey players in order to improve motor abilities and aerobic fitness as physical requirements for hockey players.
