Gastrocnemius muscle

oxygen uptake (VO2max) is a primary measurement of aerobic fitness which typically improves with TE. Mitochondrial density, skeletal muscle oxidative capacity, skeletal muscle metabolism, and skeletal muscle capillarisation are also factors that affect aerobic performance.1,5 However, SIT has typically been thought to not have as high of an effect on skeletal muscle aerobic capacity as traditional endurance. A key adaptation that occurs with…

Press 1a. Shoulder extension (primary), elbow extension (secondary) 1b. Deltoid (Primary), trapezius (Secondary), levator scapulae (secondary), triceps (secondary) 1c. Rationale: The deltoid is the main muscle used in the shoulder press but to complete this lift properly the upper back muscles must be contracted as the shoulder and elbow extend to raise the bar overhead. In the eccentric phase the elbows and shoulders flex. Defense 2. The movements of the shoulder press translate into holding…

the obvious muscle that must be toned, but few people realize that the core, arms, neck, and back must have a strong muscular background as well. These muscles work together to contribute to the success of a soccer player. Injuries to the muscles happen often, but this risk of injury can be minimized with flexibility training. Multiple different training techniques are incorporated and three different energy systems are present for a soccer player to achieve optimal performance. Muscle Groups…

of injury or scar tissue that can build up along the fascia of overused muscles, a loss of range of motion within the foot is often seen amongst many patients. This often leads to inefficient and compromised movement in both the foot and lower leg area. All too often these symptoms are not treated until they have developed into the form of debilitating conditions. (www.tptherapy.wordpress.com 29.05.16). The primary muscles involved in dorsiflextion of the…

Skeletal muscles are made of three different muscle fiber types. All muscle fibers are having varying amounts of mitochondria in them. Mitochondria helps the muscle be able to manufacture ATP for contraction. To differentiate between the three muscles is based on their make up. Slow oxidative (SO) or type one muscle fibers are composed with the most mitochondria to help them be fatigue resistant. SO muscle fibers stain the darkest because the enzyme targeted by the stain is most abundant in this…

Muscle cells play a very important role in movement of our body. There are three types of muscle cells in vertebrates: skeletal, cardiac and smooth. We are mainly going to be concerned with skeletal muscle for this particular experiment. The skeletal muscle is responsible for the voluntary movement of whole body or body parts, manipulation of external objects, support for our skeleton (Sherwood, 2010, p257). Skeletal muscles have a striated structures of alternating light and dark bands…

and expose the gastrocnemius muscle. The gastrocnemius muscle was first separated from the tibiofibula bone, but left attached to the knee and the Achilles tendon. A 15 cm long piece of strong thread was tied tightly around the Achilles tendon of the heel of the frog for later attachment of the muscle to the force transducer equipment. The Achilles tendon below the tied string was then severed and the tibiofibula and femur bones were cut away and removed. The gastrocnemius muscle was kept moist…

trunk in an upright position, and use the muscles in the leg instead of the back (Early, 2013 pg 191).Proper body mechanics for the activity of tug of war, would be to stand in a staggered squat position, with one foot out while the other is lined up with the hip. Secondly, your trunk should be upright, even while pulling on the rope the trunk should remain in an upright position. Use your leg muscles to keep your stance, however you will use the muscles in your arm to pull the rope. While…

with the best lighting possible in a sagittal view to allow the best view of the hip’s range of motion and angles. Results: Many people do not properly perform correct squat biomechanics often leading to injury. The prime movers of a squat are the muscles around the hips and knees, but it also includes the ankle foot and lower back. Image 1 demonstrates a comfortable stance; most people prefer their feet slightly wider than shoulder width apart with their toes pointed out at a slight angle…

Definition/ Anatomy The Achilles tendon is the supposedly strongest tendon in the human body. Tendons attach muscles to bones; in this case the tendon of insertion of the two muscles soleus as well as the gastrocnemius is the Achilles tendon, which is often a typical cause of distress for athletes in sports such as tennis, basketball, and soccer, as well as other athletic activities involving running, jumping, and rotating movements (Behnke, 2012). Reasons for Achilles Tendon Rupture and…
