Introduction
Daily activities performed by human beings is a certain way call for the use of force and energy in executing them. This energy is got from well feeding to ensure that the body muscles, joints, and bones stand up to the necessary task of undertaking a specific activity without much strain or getting tired without completion of the work or activity. Due to this, one must ensure that the body as a whole is fit to undergo the strain brought by the practise exercise to develop the muscles, bone, joints, and the body as a whole.
Principle of specificity is on of the principles that are broadly used by athletes all over the world. It involves the training undertaking with the intention of building specific muscle that are strained during a specific activity or sport. A good example of such exercise is an activity carried out by the triathletes who ride bikes laying strain on different muscles that are specifically used during the running process. Athletes used specific muscles while running.
Overload principle
For a specific muscles to develop in the body, it must undergo some strain targeted in the development of the muscle to ensure continuous growth of the muscle at the intended regions. Looking at the exercise such as bench press intended to develop chest muscles and arms. Continual addition of the weights lifted at any particular training session is important for the continuous development of the muscles. A training session such as light walking is good for beginners but does not meet the criteria. This is because it reaches a maximum limit of straining the muscles that in turn limits the growth of the muscles over time.
Origin of the muscles
Pectoralis major is a muscle that originates from the sternum, clavicle and the cartilage of the ribs one to six or the seventh one. Humerus is the insertion of pectoralis major muscles found in the body.The primary function of the muscle is the prime movement of the arm and adducts and medial rotation of the arm. Bicepes former originates from the linea aspera, distal femur and the ischial tuberosity. Insertion of the muscle is the fibula head and lateral condyle of the tibia. Its function is to extend the thighs and flexing of the knee.
Obstacle of the weak link
Development of the biceps with weak forearm muscles is an example of a weak link that can be noticed in the human body. This limits the exercises and activities that can be performed using the form or a combination of both muscles. The forearm is the weak link in this case due to less emphasis put on the muscle during training or the limitation of exercises available to develop the muscle. This issue can be solved by engaging in exercises that strain the forearm muscles developing them over time.
Components of a motor unit
In the human body, the motor unit is composed of a motor neuron and skeletal muscle which are innervated by the neurons terminals called te axonal terminals. Movement of muscles in the human body is done through a series of coordination by the nervous system. Synapse aids in the transfer of information from one cell to another for coordination. The ACH function is to act as the neurotransmitter that conveys messages between receptor and effector neurons through a series of chemical action. Threshold is used for the communication between cell and also activate intracellular actions such as production of more energy. Synaptic cleft aids in the raising of communication of the nerves to the concerned muscles to enhance a certain type of intended movement during a synapse.
Two types of motor unit and differences
The two types of motor unit refer to the available types of motor sensors in a human consisting of the sensor neurons, effector and the muscle fibers involved. The muscles are the one's heavy muscles with many fibres and light muscles responsible for light tasks of the body. For example, thigh muscles have a lot of fibres for the heavy work and response such as flight during danger after release of adrenaline hormones. Lights muscles are responsible for light work.
Primary joint action
a) The movement involved the raising of the upper arm to the front.
b) The type of movement involved in this phase is the forward movement of the hip joint in a squatting position.
c) During this phase, the knee movement is forward in a squatting position an example the weight lifters in an Olympic competition.
d) At this phase, the biceps muscles contract to pull the forearm up.
e)Involves the use of ankle joint plantar flexors muscles in the uplift of the ankles during exercises such as the squat and such.
f) Triceps Anconeus are the muscles involved here in the extension of the elbow joint.
