Retired Professional Interview The agricultural and extension education profession has changed and developed over time. As a future worker in this career, I need to know more about the agricultural and extension education profession and how it developed with time. In order to fully understand that, I interviewed the retired extension worker in Mississippi State. He is known as one of the top soybean specialists in the US. This interview took place on Monday, March 21, 2016 at Starbucks on Highway 12 in Starkville, Mississippi. My interviewee was Dr. Alan Blaine, who co-founded the Southern Ag Consulting with two of his graduate students in 2008. Furthermore, he co-founded the Alliance Ag Risk Management in 2009. Besides the two companies, he manages his own timber, hay, and cattle farm. Dr. Blaine has a doctorate in Agronomy with a minor in Plant Pathology from Mississippi State University. He earned his master’s in Agronomy with a minor in Plant Pathology, and a bachelor’s in Animal Science from Mississippi State University. In the agricultural and extension education career Dr. Blaine spent nearly 27 years from his entire life. He started his profession in 1982, and he retired in 2008. During Dr. Blaine’s career at MSU…
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…
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…
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…
Firstly, bipeds move by using two rear limbs whilst quadrupeds move by using four rear limbs. Both bipeds and quadrupeds use distinct gaits for locomotion. A gait is defined as a particular style of movement. Animals’ characteristic legs and gaits are due to natural selection and experiential learning. [1] Several different properties are used to classify gaits, these are outlined below. A stride is one complete cycle of leg movements. Stride frequency is the number of strides taken in a…
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…
