Muscles Used By a Rowing Machine
The rowing machine is an excellent full-body workout equipment that can help to enhance your cardiovascular function, strength, build muscles and burn calories. Rowing is one of the few exercises that can be done by people who have knee pains or weak joints because it is a low-impact workout. The rowing machine is said to work 84 percent of the muscles in the body, which is why it is so effective at building muscles. Getting the best out of the rowing machine requires learning the proper technique, and the knowledge of the muscles used by the rowing machine can help you to concentrate and put in your all so that you can reap the maximum rewards of rowing. In this piece, you will learn about the various muscles

During the catch, your legs are bent while your shins are vertical. The erector spinae muscles relax so that the abdominals can flex the trunk. The pelvis and hips are flexed by the psoas minor and major as well as the iliacus. To allow the body achieve maximum reach, the Sartorius muscle rotates the thighs to provide flexion for the body. During the flexion of the knees, the gastrocnemius and hamstrings are contracting. Meanwhile, the rectus femoris help the flexion of the hip, while the quadriceps are stretched and elongated. The tibialis anterior helps to flex the ankles dorsally. The flexor muscles of the fingers and thumb help the hand to grip the handle, while the triceps brachii help to extend the elbows.
The Drive
At the initiation of the drive, the leg supplies all its power. The knee is extended by the quadriceps, while the gastrocnemius and soleus muscles help to flex the feet in a linear direction. The lower back is supported by stabilizing muscles. During the drive phase, the entire muscles of the shoulder such as the biceps brachii, supra and infraspinatus, teres major and minor, and the subscapularis are contracting. The trapezius and serratus anterior muscles help to provide stability for the scapula.

The extension of the back and hips are almost complete, while the muscles of the upper body are contracting powerfully to complete the drive. At the stage, the elbow flexors do the heaviest work. The extensor carpi ulnaris and the flexor muscles of the forearm contract to stabilize and draw the wrist closer to the body. The shoulder is also drawn to the body and extended. The pectoralis major and latissimus dorsi rotate the upper arm internally. Meanwhile, the biceps, posterior deltoid, and teres minor are working on the joints of the shoulder. The pectoralis minor rotates the scapula downward while the rhomboid and trapezius muscles draw it
In the frontal plane, the movement shows the depression of scapula. The joint involved in this part of the pirouette is the scapulothoracic joint. This motion can be analyzed in the frontal plane or the sagittal due to the movements of the shoulders with the trunk (Hall, 2011). In the transverse plane it is the external rotation of the hip that helps form a pirouette. The muscles used to perform the rotation are the gluteus minimus, piriformis, superior gemellus, inferior gemellus, obturator internus, obturator externus, and quadratus femoris (Hall, 2011). These muscles are used to help the leg move to the correct position for a pirouette.
The gluteus maximus originates from both the ilium and the sacrum and inserts on the femur. The gluteus minimus abducts and rotates the thigh outward. The biceps femoris originates from the tuberosity of the ischium and is responsible for abducting the thigh and flexing the hindlimb or in humans the thigh/leg. The gastrognemius originates from the lateral sesamoid bone of the femur and extends the hindfoot in minks and the calves in humans (Scott).
Flexion is the bending of a joint so that the angle between the two bones decreases. The primary muscles that flex the knee are a group collectively known as “hamstrings.” The hamstrings consist of the biceps femoris, semitendinosus, semimembranosus. The muscles that assist in flexion are the sartorius, gracilis,...
Talus (Ankles): To start and stop quickly. Tibia, Patella (Knee): To bend over to hit the lower shots. Muscles used in tennis serve When serving a tennis ball, all the muscles of the body are involved, since you are throwing a ball up, taking a step back and then swinging your arm forward to hit a ball using the whole of your body for follow-through.
When performing manual muscle testing for shoulder flexion and abduction, PTA’s typically place their hand at the wrist verses the mid-extremity because placing their hands at the wrist increases the length of the lever thus testing the muscles ability to resist externally applied force overtime and across the bone-joint lever arm system. Shorter lever arms will provide higher testing scores when compared to using longer lever arms, thus changing the point of force application affects the length of the lever arm and therefore the muscle torque.
The flexor tendons are not involved, although it may appear so in advanced contractions. Trauma may accelerate and in some cases even begin the process.
This report will explore the structure and function of skeletal muscle within the human body. There are three muscle classifications: smooth (looks smooth), cardiac (looks striated) and skeletal (looks striated). Smooth muscle is found within blood vessels, the gut and the intestines; it assists the movement of substances by contracting and relaxing, this is an involuntary effort. The heart is composed of cardiac muscle, which contracts rhythmically nonstop for the entire duration of a person’s life and again is an involuntary movement of the body. The main focus of this report is on skeletal muscle and the movement produced which is inflicted by conscious thought unless there is a potentially harmful stimulus and then reaction is due to reflex, as the body naturally wants to protect itself. Skeletal muscle is found attached to bones and when they contract and relax they produce movement, there is a specific process that the muscle fibers go through to allow this to occur.
Joints which include rotation is the shoulder joint and the hip joint, this allows us to move the bones connecting to that joint in a wide range of directions. This type of rotation can also be broken down into two types of rotation: medial and lateral (internal and external). Ball and socket, condyloid and plane joints allow this type of movement. Internal rotation of the arm is when the arm is flexed but it moves towards the centre (midline) of the body. However external rotation of the arm is when the arm is flexed, but it moves away from the midline of the
The source expands on three major groups of muscular systems. They are skeletal muscle, Cardiac muscle and smooth muscle. Skeletal muscles are made up of muscle tissue, connective tissue, nerves and blood vessels that is attached to tendons and bones. Cardiac muscles are small with short wide T-tubules and is only found in heart. Smooth muscles are long, slender and spindle shaped with no T tubules, myofibrils or sarcomeres that arrange the blood vessels in some organs. All these three types of muscles are grouped together with fibers that
As you can see by the diagram, the muscles cover the entire body as does the integumentary system. They are responsible for movement. They are attached to the bones (skeletal system) and there are nearly 700 different ones. Each is made up of the muscle tissue, blood vessels, tendons and nerves. Each has a specific purpose. For example, the leg muscles assist in moving and bending the legs. The muscles make up nearly half of a person’s total body weight.
The three types of muscle cells are cardiac, skeletal, and smooth. Cardiac muscles are only found in and near the heart. They push blood through the heart, and are involuntary (not controlled by the nervous system). Skeletal muscles are attached to the tendons and bones. They stabilize joints, help with posture, and power voluntary movement. Smooth muscles are found in organs. They work together to move substance like food through the body, and are involuntary. Muscles use proteins called actin and myosin to move. Calcium ions bond actin and pull it apart, which opens a place for myosin will bond. Actin and myosin push and pull against each other, which causes the expanding and contracting.

The purpose of the squat is to train the muscles around the knees and hip joints, as well as to develop strength in the lower back, for execution of basic skills required in many sporting events and activities of daily living. Because a strong and stable knee is extremely important to an athlete or patient’s success, an understanding of knee biomechanics while performing the squat is helpful to therapists, trainers, and athletes alike (11). Because most activities of daily living require the coordinated contraction of several muscle groups at once, and squatting (a multi-joint movement) is one of the few strength training exercises that is able to effectively recruit multiple muscle groups in a single movement, squats are considered one of the most functional and efficient weight-bearing exercises whether an individual’s goals are sport specific or are for an increased quality of life
Cardiac muscle is a type of involuntary muscle found only in the walls of the heart, specifically the myocardium. Cardiac muscles contract automatically to tighten the walls of the heart in a rhythmic fashion (pp.212-216). The heart beats nonstop about 100,000 times each day (p.18). Smooth muscle is a type of involuntary muscle found within the walls of blood vessels such as in small arteries and veins. Smooth muscle is also found in the urinary bladder, uterus, male and female reproductive tracts, gastrointestinal tract, and the respiratory tract. Skeletal muscles are voluntarily controlled and are attached to bones by tendons. Skeletal muscles also vary considerably in size and shape. They range from extremely tiny strands such as in the muscle of the middle ear as large like in the muscles of the thigh (Martini, 2000). The three individual muscle types also serve five main functions. The five basic functions are movement, organ protection, pumping blood, aiding digestion, and ensuring blood flow.
The muscular system is a very important part of the human body. It has many components and functions, and is the source of the body’s movement. There are roughly 650 muscles in the human body and are different types of muscles. Muscles can either be voluntary or involuntary which means controlled or uncontrolled movement. Muscles have many reasons and in this paper you will widen your knowledge of muscles and their functions as well their diseases and how they help maintain the body.
