While individual muscle units' contract as a unit, the entire muscle can contract on a predetermined basis due to the structure of the motor unit. Motor unit coordination, balance, and control frequently come under the direction of the cerebellum of the brain. This allows for complex muscular coordination with little conscious effort, such as ...
Muscle & Fitness has a more mainstream fitness and bodybuilding lifestyle focus than its companion publication, Flex, which mainly covers more specialised "hardcore" and professional bodybuilding topics. It offers many exercise and nutrition tips, while at the same time advertising a variety of nutritional supplements from companies.
Contraction is achieved by the muscle's structural unit, the muscle fiber, and by its functional unit, the motor unit. [4] Muscle fibers are excitable cells stimulated by motor neurons. The motor unit consists of a motor neuron and the many fibers that it makes contact with. A single muscle is stimulated by many motor units. Muscle fibers are ...
Common superset configurations are two exercises for the same muscle group, agonist-antagonist muscles, or alternating upper and lower body muscle groups. [29] Exercises for the same muscle group (flat bench press followed by the incline bench press) result in a significantly lower training volume than a traditional exercise format with rests. [30]
Physical fitness is a state of health and well-being and, more specifically, the ability to perform aspects of sports, occupations, and daily activities. Physical fitness is generally achieved through proper nutrition, [1] moderate-vigorous physical exercise, [2] and sufficient rest along with a formal recovery plan. [3]
As muscle hypertrophy is a response to strenuous anaerobic activity, ordinary everyday activity would become strenuous in diseases that result in premature muscle fatigue (neural or metabolic), or disrupt the excitation-contraction coupling in muscle, or cause repetitive or sustained involuntary muscle contractions (fasciculations, myotonia, or ...
