Investigations were conducted on three groups of subjects table tennis players at the Olympic Center - Bistrita (n = 5/group, age = 20.1 ± 0.5 years, G = 69.98 ± 0.3 kg, I = 173.5 ± 5.4 cm). Program effort, with the consent of the subjects, covered, for all lots: two weeks of specific training for 1 hour robot (machine throwing balls) with a frequency of 60 balls/min., with permanent change of directions of throw; robot is used for specific training in table tennis. Loads were studied: group I - control; group II - preload daily glucose, 250 ml of an aqueous solution with a concentration of 30% glucose, 2 hours prior to training; group III - day post-load glucose, 300 ml of an aqueous solution at a concentration of 40% glucose in 2 doses of 150 ml, 30 minutes and 60 minutes after the end of training. Determinations: indirect determination of aerobic capacity, pre- and post-training, 2 weeks after Astrand-Ryhming method; indirect determination of anaerobic exercise capacity, pre- and post-training, 2 weeks after the method used by the Center for Sports Medicine, Bucharest. Conclusions: Administration of glucose supplements to table tennis players train daily causes significant increases in aerobic and anaerobic exercise capacity, which can contribute to increased performance. Glucose supplementation pre- and post-effort, determined to improve predominant aerobic capacity. [ABSTRACT FROM AUTHOR]

This research paper studies the physical improvement of human operators for the increasing of physical potential and health. The main goal is that on the basis of scientific research, the progress of miners must be highlighted, through the implementation of the program that should increase health through a better functioning of the loco motor apparatus and the improvement of individual physical performance for each individual. In this research, we aimed to analyze the following aspects: the initial physical state of a group of 20 human operators, the performance of human operators individually and in groups, carrying out a program of activities driving health. Specifically, we investigated the following sub-themes: perception operators, human to sports, objectives and motivation of human operators to perform sports activities, ability to objective comparison with other similar groups, attitude towards their performance and attitude towards group performance. Research feasibility study for increasing the capacity of service of underground mining by improving the physical condition consists of three stages: stage adaptation of the body to physical activity to improve fitness stage and stage personalizre preparation and maintenance of fitness.
