Exercise Physiology Essay

Introduction Genetic diseases are being discovered more often as we learn the affects that genes have on the body. McArdle’s disease is a metabolic disease that affects skeletal muscle because of a gene mutation. The genetic mutation prevents the creation of the enzyme myophosphorylase. This enzyme is responsible for the breakdown of glycogen in muscles (Haldeman-Englert, 2014). McArdle’s disease is also known as Type V Glycogen Storage Disorder. It affects approximately one out of every 100,000

Purpose The overall purpose/hypothesis of the article, was it to find out how physical activity is linked to the preservation of neurocognition, but more specifically to address the fundamental question-- “does exercise improve cognition?” (Masley et al., 2009). The secondary reason for this study is to use a technological method to determine the field of cognitive domains, in relation to memory, mental speed, reaction time, attention, and cognitive flexibility. Subjects The subjects from this

table 1. Muscle Soreness Regarding muscle soreness, the pre-exercise values were not different among groups. Muscle soreness significantly increased above baseline in all groups at all time points (p < 0.05; Fig 2). Peak soreness occurred in all groups at 24 hrs after exercise. Also, the three groups had no effect on soreness scores. Serum Marker Means CK levels are presented in Fig3. CK level reached its peak activity 48 hours after exercise with significant differences

Introduction An important goal in the post-exercise recovery period is to provide the body with appropriate substrates in sufficient quantities to achieve optimal repletion, adaptation, and subsequent performance. Three processes during the limited recovery period are known to be nutritionally enhanced: glycogen repletion—requiring carbohydrates, muscle protein synthesis—requiring protein, and rehydration—requiring fluid and electrolytes. Yet, athletes of a full spectrum of competitive levels

triphosphate (ATP) produced through the oxidative phosphorylation cycle. Half the creatine in the body is obtained from dietary creatine, mainly from meat and fish. Nevertheless, this amino acid is used as a supplement in a wide range of disease and exercise settings to increase creatine utilization and availability. Supplements are commonly used orally in the form of creatine monohydrate. Main effects of creatine Creatine supplementation helps to improve muscle size and power of contraction, but can

athletes can stand to benefit from wearing compression clothing while taking part in sports or exercising. Due to improvements in the way the body handles oxygen and blood during aerobic activity from wearing this type of clothing, intensity of exercise can be increased and endurance-related benefits may also be experienced. Not only can compression clothing promote recovery from injuries, compression clothing also commonly features thick padding that eliminates excess sweat produced by the body

Whether it be elite athletes or weekend warriors, all athletes have experienced muscle tightness that impacted their athletic performance. I wanted to investigate whether instrument assisted soft tissue mobilization (IASTM) was more effective at reducing hamstring muscle tightness than foam rolling in high school athletes. Most high school athletes work very hard at practice and in the weight room and therefore, hamstring muscle tightness is very common. I chose the high school population because

Air pressure is the force that the air throws Weight and mass have effects on the soccer ball If the ball weighs more it is more difficult to kick it Friction prevents the soccer ball to keep going forever because it slows down the ball Gravity stops the ball from floating away forever Momentum affects how far the soccer ball goes Movement means the act of moving Newton was a scientist who created the laws of motion Newton’s first law of motion is also known as the law of inertia When the ball is

Overview When you exercise, it stimulates the autonomic sympathetic nervous system. One of the most effected bodily systems is the cardio-respiratory system. Any change in the intensity of an activity changes the needs of you body. During exercise your heart and breathing rates increase noticeably. The change is due to the increased needs of oxygen and other nutrients to the muscles in the body. Circulatory System Exercise uses up a lot of energy, which the cells derive from oxidizing glucose

Exercise is dependent on skeletal muscle contraction and relaxation via energy released from the breaking of the high­energy phosphoanhydride bonds of ATP. ATP is generated from ADP+P​i​using energy derived from the metabolism of macromolecules such as proteins, carbohydrates, and fats. Mild or moderate exercise uses primarily fats as the energy source for K​ ATP generation. Mild exercise is not limited by depletion of energy substrate. ​Oxidative phosphorylation provides most of the ATP requirement
