Physiology of fitness Acute exercise lasts for the length of a training session. During this time our bodies respond to the exercise and physical stress of the physical activity in lots of different ways. These are called acute responses. Acute responses immediate responses to exercise‚ such as an increase in body temperature and heart rate. Musculoskeletal response The musculoskeletal system allows and enables the body to move through a system of muscles‚ bones‚ tendons‚ cartilage and ligaments

Exercise is purposeful physical activity that is planned‚ structured‚ and repetitive. There are numerous benefits of completing exercise on the regular. There is a major difference between physical activity and exercise. Physical activity is any form of movement that uses energy. Exercise is movement and uses energy‚ but it is structured and more intense than regular physical activity. An example of physical activity is walking through the hallways between classes. An example of exercise is sprinting

Lab #3: Isotonic contraction and the effect of load on skeletal muscles Abstract The job of the motor nervous system is to control certain elements in muscles simultaneously to ultimately produce movement. Movement of the body is the result of specialized cells directly associated with skeletal muscle. Skeletal muscles are voluntary muscle and must contract before movement can occur. We know the muscle team moving the arm is formed at the biceps and triceps. Biceps can bend the elbow‚ but

Skeletal Muscle Physiology: Frogs & Human Subjects (1‚ 2‚ 5-8‚ 10-12‚ 14-16) 1. There is a greatr concentration of Na+ f ; there is a greater concentration of K+ e . When the stimulus is delivered‚ the ermeability of the membrane at that point is changed; and c ‚ initiating the depolarization of the membrane. Almost as soon as the depolarization wave has begun‚ a repolarization wave follows it across the membrane. This occurs as b . Repolarization restores the h of the resting cell membrane

Review Sheet Results 1. Explain why increasing extracellular K+ reduces the net diffusion of K+ out of the neuron through the K+ leak channels. Your answer: If the extracellular K+ increases then the concentration of intracellular K+ will decrease causing a decrease in the steepness of the concentration gradient and fewer K+ ions would be drawn out. 2. Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value. How well did the results compare
