but on intensity zones
Muscles are the most important tissue in the body. Skeletal muscles are under direct volitional control and provide movement of the body in space and maintain posture. Regardless of the type of physical activity, the function of muscle tissue is the manifestation of contraction force and the use of the necessary energy for this.
Muscle strength depends on the cross-sectional area of muscle fibers and the degree of activation of the motor units that make up the muscle.
The increase in strength under the influence of training occurs due to two physiological mechanisms: due to working muscle hypertrophy and improved intramuscular coordination, which leads to an increase in the number of motor units that can simultaneously contract. Continue reading
