INTRODUCTION
Nowadays scientists still search for the ways of physical training optimization among students of higher educational establishments. Among them we define: the use of different kinds of sport elements, exercises with dumb-bells, interval and circular training, active games. It is a well-known fact that the base of physical training is physical qualities development. One of the most important for students are different kinds of endurance, quickness and power oriented qualities. These qualities development is possible only in terms of influence on their physiological basis and in particular on the mechanisms of muscle activity energy supply.
In most works, which are dedicated to students' physical training, there is no sufficient
information. It characterizes the peculiarities of muscle activity energy supply and their use for physical training process differentiation.
MATERIALS AND METHODS
The students of the ist-3rd course (girls and boys) from three medical groups (main, preparatory, special) took part in the research - 175 female and 175 male students from Izhevsk State Agricultural Academy in Izhevsk, Russia. As the initial results we took the reserve and functional abilities of the 1st course students.
The method of express diagnostics of the functional state and reserve abilities of an organism [4,5,6,7] was used in order to define the students' bioenergetics types [8-12]. The program analyzed
n
the height of R and S waves of electrocardiogram. It was taken in standard and group leads. As a result the indices are calculated, which characterize power, capacity, efficiency of anaerobic and aerobic systems of muscle activity energy supply:
1. ANAMC - capacity of anaerobic energy supply source, characterizes the ability to fulfill the load in the 3rd, 4th and the 5th zones of intensity.
2. ANAMC% - capacity of anaerobic utilization, characterizes propensity for anaerobic work in percentage.
3. AMC - capacity of aerobic source of energy supply, characterizes the ability to fulfill the load in the 1st and the 2nd zones of intensity.
4. AMC% - capacity of aerobic utilization, characterizes propensity for aerobic work in percentage.
5. GMC - general metabolic capacity, characterizes general working capacity of an organism.
6. PCP - power of creatine phosphate source of energy supply, characterizes speed-power oriented abilities.
7. PGS - power of glycolytic source of energy supply, characterizes speed and power oriented endurance.
8. PASES- power of aerobic source of energy supply, characterizes the ability to demonstrate general endurance and to realize rehabilitation after anaerobic work.
9. WTANM - threshold of anaerobic metabolism, characterizes the effectiveness of aerobic source of energy supply use.
RESULTS AND DISCUSSION
During the research we received positive results, presented by pictures 1-11. Let's consider the analysis according to the separate indices. Anaerobic metabolic capacity is the index.

CONCLUSION
During the research we revealed the dynamics of reserve and functional abilities of the students' organism at Izhevsk State Agricultural Academy and the differences in the students' indices at the 2nd and the3rd courses in comparison with the indices in girls and boys of the 1st course.
This research work analysis showed that the female students of the 2nd course, who belong to the main medical group, have the highest index of anaerobic, aerobic abilities and the capacity of anaerobic utilization (anaerobic genotype). The capacity of aerobic utilization (aerobic genotype) prevails among female students of the 3rd course in a special medical group. In the girls of the 2nd course in the preparatory group some indices are higher: the level of working capacity, maximum oxygen consumption, threshold of anaerobic metabolism, criterion of aerobic source use, general energetic atmosphere. Power of creatine phosphate source of energy supply (power endurance) is higher in the 3rd course female students in special medical group.
This analysis according to 9 indices among boys revealed that most boys of the main group at the 1st-3rd courses have higher values of the indices, that in the preparatory and special groups.
Boys of the 1st course in the main group have higher results, than boys of the 2nd and the 3rd course of the main group according to the following indices: anaerobic abilities, anaerobic genotype, the level of working capacity and HR TANM. In the following indices: aerobic abilities, power and speed endurance, general energetic atmosphere the values are higher among the students of the main group at the 2nd course. In the index of aerobic genotype we revealed high values among the students of the 3rd course in the main group.
