of eternal life. Some of them, such as the Philosopher's Stone or the Elixir of Life went on to be more popular. In addition to that, multiple religions also have immortality as a central part of their belief system. After years of research focused on the matter, we have reached a point where recent discoveries allow us to look past that dream and see a real possibility of extending our life span. Therefore, researchers have been trying to anticipate the consequences that the advent of such technology could bring upon us as a society. They generally have two points of disagreement concerning life extension technology. Researchers debate on whether or not life extension technology is ethically and morally acceptable. The second point concerns the future consequences this technology could have on social equilibrium. Social equilibrium can be defined here as the balance existing between…
Life extension technology is the research and application of slowing down aging process through medicine and other technologies. Bostrom and Roache objection against life extension would deprive life of meaning and exacerbate the existing social problems associated with an aging population (B&R 4). Per B&R response, that life extension technology will inevitably lead to give one’s life meaning and mark out one’s life as one’s own would eventually be completed or abandoned, leaving infinite years…
Movement: -The positioning of the bones forming the elbow joint produce the hinge synovial joint. This allows the elbow to make extensions and flexion. The extension involves the Triceps brachii and anconeus (the continuation of the tricep brachii). Flexion is involving the; Brachialis, biceps brachii, and brachioradialis. - The bending of a joint part so that the angle decreases and the two parts come closer together, it called Flexion. The straitening of a joint increasing the two parts to…
Being a biarticular muscle group it may be stretched to extremes. When hamstring tears occur during kicking, either slow or fast movement, it involves concurrent hip flexion and knee extension. At deceleration, these muscles will contract, while being promptly lengthened. Therefore, they are performing eccentric contractions (Garrett et al, 1990.). It is well established that repeated eccentric contractions have the potential to damage muscle fibres (Armstrong et al,…
positions themselves side on to the target. The main purpose of this phase is so the body can get into a rhythm which will make it easier for the throwing action to be more efficient. At the start of the wind up the athletes feet should be shoulder width apart and should be side on to the target. The athlete then extends their knee and strides outwards. This helps to develop momentum which is used in later stages of the throwing motion. This particular phase doesn’t put a lot of strain on the…
lateral lip of the intertubercular groove of the humerus. The pectorals major flexes, medially rotates and adducts the humerus. Second, the deltoid originates from the lateral half part of the clavicle (anterior fibers), the acromion of the scapula (lateral fibers) and the spine of the scapula (posterior fibers). All the fibers merge on the deltoid tuberosity of the humerus.The anterior fibers flex and rotate the humerus medially. The lateral fibers abduct the humerus. The posterior fibers…
joints and segments, and the gravitational force. The hip joint flexes doubles that of knee joint extension movements, and the smaller movement are associated with the planter flexion of ankle joint. There is a very little attention given to the examining the support leg / non kicking foot. A skilled soccer player executes a maximal instep generated flexion/extension joint movement 4, 3.2, 2.2 Nm/kg for hip, knee, ankle joint respectively where as the support leg knee, ankle and hip joint are…
Electrical stimulation: Eight self-adhesive 7x13 cm oval carbon electrodes were adhered to the skin over the quadriceps and hamstring muscles (four electrodes per leg). These muscles were selected because of their ease of access, clinical importance, and large size, which we reasoned would yield the greatest potential for altering energy expenditure. The distal margin of the distal quadriceps electrode was placed over the distal-most palpable border of the vastus lateralis. The proximal…
preparatory phase is finally being used and put to action. This is usually characterized by near-maximal concentric activity in the involved muscles (Floyd, 2012, p. 207). During this phase the shooter will jump off their feet contracting their quadriceps using their hamstring muscles. The gastrocnemius, soleus, Achilles tendon, peroneus longus, peroneus brevis, tibialis posterior, flexor digitorum longus and the flexor halluces longus musles will act in plantar flexion making the shooter able…
