In other words, explosive force is the ability to manifest large quantities of force in the shortest possible time.
Under the power endurance refers to such power abilities, in which the athlete can for a long time to maintain the appropriate power tension when performing technical actions.
All the listed strength abilities are of great importance for achieving high sports results in javelin throwing.
The strength of muscle contraction is primarily determined by the physiological diameter of the working muscle and the number of capillaries in its substance. Of particular importance is the cypionat 250 volume of myofibrils and sustanon 250 injectable steroids the number of high-threshold (large) motor units (MU) in the muscle tissue.

The manifestation of power abilities in a specific motor activity depends on the biomechanical structure of technical actions (length of arms of levers, interposition of body links, the possibility of involving large muscle groups in the work, stress values of individual muscle groups and their mutual combination, functional state of the neuromuscular system, and energy efficiency of relevant work and other factors).
Power abilities are determined by controlling, or regulating (central-nervous), and controlled, or executive (muscular), factors combined in the body by direct and inverse connections in the neuromuscular system, which, interacting with other systems of the body, contributes to the achievement of certain sports results .
The control systems include the corresponding sections of the cerebral hemispheres and the motor neurons of the anterior horns of the spinal cord, as well as the body’s analyzer systems that regulate the executive muscle factors.
Nervous regulation is determined by:
– the number of “included” in the work of;
– the frequency of nerve impulses entering the muscle along the nerve paths from the central how to use sustanon 250 nervous system (CNS);
– the degree of synchronization of the activities of those involved in muscle tension;
– trophic effects of the central nervous system, carried out through the activities of the sympathoadrenal system.
The efficiency of movement performance is controlled by analyzer systems (proprioceptor and articular sensitivity). Information on the sensory (afferent) nerve paths enters the spinal cord and brain, which corrects muscle tension.
The cipro 250 mg oral tablet manifestation of power abilities largely depends on the so-called reactivity of the muscle itself, i.e. from the strength with which she responds to a certain impulse.

The muscle reactivity is primarily determined by:
– physiological diameter (sectional area);
– macromorphological and histological structure;
– the length of the moment.
In those cases where muscle tension reaches the limit of activity, its regulation is based on the synchronization of the work of the DE.
When muscle tension, when they cypionat 250 do not reach the limit values, the regulation of muscle strength occurs due to changes in a different number of EH, included in the work.
Training muscle strength is aimed at improving both central and muscular factors.
The first factors are associated with an increase in the excitability and lability of the central nervous system, its motor sphere, ensuring the mobilization of the maximum possible amount of CU and the maximum use of their power capabilities (intramuscular coordination). This also includes the formation of the optimal sequence and the ratio of the on and cypionate 250 results off of the corresponding groups of physical exercises or muscle groups (intermuscular coordination).
Intramuscular coordination is improved more successfully with the use of limiting and near limiting burdens with which the exercise can be performed without additional rest from 1 to 3 times. In this case, the most stimulated involvement in the activities of the maximum possible number of MU.
To build muscle the most effective is the use of smaller burdens, with which the exercise can be performed without additional rest from 5 to 10 times. In this case, the synthesis of contractile muscle proteins is stimulated to the greatest extent.
The effectiveness of strength training is enhanced if exercises are included in it not only in the overcoming mode, but also in the isometric and inferior modes. At the cipro for uti 3 days 250 same time, new demands are placed on the muscular system. The fact is that in the isometric mode, the muscles are able to show greater strength than in the overcomer. The inclusion of strength exercises with different mode of the muscles allows you to vary the methods of training and creates a favorable background for the development of strength.
In the practice of sports training, the following combinations of muscle modes are most appropriate:
a) after the inferior mode – overcoming;
b) after the overcoming mode – isometric;
testosterone 250 side effects
c) after the isometric mode – overcoming.
In the scientific and methodical literature cypionat 250, 3 main methods of developing strength are recommended:
1. The method of repeated efforts – provides for the re-raising of unsaturated weight to pronounced testoviron depot 250 bodybuilding fatigue (“to failure”);
2. The method of maximum effort – provides for raising the maximum weight;
3. The method of dynamic efforts – provides for raising the unsaturated weight with the maximum speed (the description of this method will be made in the next section – “Improving speed-strength preparedness”).
When using the method of repeated efforts (“to failure”), at first the force of the physiological stimulus is not maximal, as a result of which the development of muscle strength is not stimulated. And only with the last repetitions, when fatigue develops as a result of repeated repetition of the exercise, and the resistance to be overcome becomes the body’s maximum physiological stimulus, does the development of muscle strength occur. This is explained by the fact that with the number of repetitions, more and more testosterone enanthate 250 cycle EGs are gradually included in the work, and in the last repetitions their number rises to a maximum. This increases the frequency of effector pulses and their synchronization is observed. The concentration of effort changes, which leads to an increase in muscle strength. This method is most appropriate in the preparation of beginner athletes.
Its advantages are due to the following provisions:
1. There is an increase in trophic processes due to a larger amount of work performed, which leads to functional muscle hypertrophy and thereby causes an increase in muscle mass and, consequently, strength.
2. When using local exercises, the straining associated with breath holding, which occurs when using exercises with extreme stresses, is reduced.
3. The use of exercises with unsaturated power stresses provides more opportunities to control the technique.
For highly skilled athletes, this method can also be used to prevent injuries after speed strength and speed work, because it activates trophic processes.
In the training process there are several options for applying the method of repeated efforts:
– performance of the exercise in one approach “to failure”, the number of approaches – not “to failure”;
– “to failure” exercise is performed only in the latter approaches;
– an exercise with one approach is performed “to failure”, the number of approaches is also testabol 250 “to failure”.
The disadvantages of the repetitive effort method are: a) energetically disadvantageous, since you have to perform a much larger amount of training work than when using the maximum effort method; b) the last attempts are performed against the background of a decrease in the excitability of the central nervous system due to fatigue, which complicates the formation of subtle coordination bonds.
The application of the maximal effort method is most appropriate in the training of the power capabilities of highly skilled athletes. Its main effect is to increase the maximum force, which is determined by: a) the simultaneous inclusion of the greatest number of EUs; b) the maximum frequency of efferent impulses;
c) synchronized rhythm of DE activity.
There are several variations of this method:
1. Method of maximal and maximal concentric muscle contractions.
how good is sust 250 by dna
2. The method of maximum eccentric muscle contractions.
3. The testosterone enanthate 250 for sale method of maximum concentric – eccentric muscle contractions.
4. The method of maximum isometric muscle contractions.
For the first variant (the method of near-maximal and maximum concentric muscle contractions), it is typical to perform exercises mainly with limiting and limiting resistance (weight), which can be overcome (lifted) without significant emotional arousal 1-2, maximum – 3 times.
The maximum load when using this method with near-maximal and maximum resistances for highly qualified athletes can reach 30-40 repetitions in one exercise. Rest pause between sets (series) – 3-5 minutes.
In the preparatory period, this method in the training process can be applied from 3 to 4 times a week, in the competitive period – 1-2 times. As a form of checking the level of strength training, this method can be applied during the whole annual cycle of classes (except for the transition period).
For the second option (the method of maximum eccentric muscle contractions), it is typical to perform training exercises with the creation of maximum power stresses in the mode of inferior muscle work. The weight of the burdens can reach 150% of the maximum weight that the athlete can lift in overcoming. In one training session, 3-4 series of 5-6 repetitions sustanon 250 price are performed. A pause of rest between repetitions – 3 seconds, between series – 3-5 minutes.
