Sports training methods have evolved tremendously over the past years, so that they become suitable for players, and the coach has been constantly following up on everything new in the field of training in order to be able to provide the best and best thing in this field and raise the level and performance of his players. From this standpoint, sports training can be viewed as a process in which different training methods and means are developed and used with the aim of changing the trainee's condition according to a pre-determined goal.
Research objective: The research aims to identify the proposed training program and its effect on muscle strength responses and some physiological variables for Junior volleyball.
Research hypotheses: There are statistically significant differences between the pre and post measurement of the experimental group in some responses to muscle strength and some physiological variables in favor of the post measurement. There are statistically significant differences between the two dimensions of the experimental and control groups in some muscle strength responses and some physiological variables in favor of the experimental group
The research sample: The research sample was deliberately chosen from among the volleyball juniors registered with the Egyptian Volleyball Federation, and the total number of the research sample reached (25) volleyball juniors. The main research sample (20) youngsters were divided into two equal groups, one experimental and the other controlling, each of them (10) juniors, and the two researchers conducted homogeneity in height, weight, chronological age and training age
Conclusions: In light of the objectives and hypotheses of the research, within the limits of the sample, and based on the results of the statistical treatments, it was possible to conclude that:
The simultaneous training program has proven effective in improving right-hand grip strength, left-hand grip strength, leg muscle strength, back muscle strength, and oblique prone, arm bending and shuttle running 5 x 55 meters
The simultaneous training program has proven effective in improving the volume of exhaled air per minute during exertion, the number of breaths per minute during exertion, the volume of inhalation air at one time, the percentage of oxygen in the air of oxygen in the exhalation, the percentage of carbon dioxide in the exhalation, the maximum absolute oxygen consumption and the maximum oxygen consumption Relative volume of CO2 produced per minute, respiration factor, heart rate, oxygen pressure, pulmonary ventilation, and respiratory fitness factor.
