What is exercise physiology? Exercise physiology is the science that describes‚ explains and uses the body’s response to exercise and adaption to exercise to maximise human physical potential. Exercise physiology is very important in touch because the amount of physical activity our body can tolerate‚ the better we will play for the longest amount of time. ATP/CP system is used by the body to produce ATP quickly in the absence of oxygen. High intensity activities lasting for less than 10 seconds

well. The process of testing an instrument’s accuracy is known as calibration. The purpose of this lab was to calibrate a variety of equipment frequently utilized in the Exercise Physiology lab and to become familiar with the operation of the calibrated equipment (Lab manual). The equipment calibrated in the exercise physiology lab was the speed of the Parvo treadmill‚ the incline of the Cosmed treadmill‚ the resistance of the ergometer‚ and the measurements of the Detecto and Chatillon scales.

Lab 4: Skeletal Muscle Function Exercise 5: The Length-Tension Relationship Materials and Methods In this experiment I used a frog anesthetized with ms222. The frog’s skin is cut and removed from both the legs‚ the Achilles tendon is cut and the tendon and calf muscle are removed from the lower legs. The femur muscle is also cut. Attached to the legs are femur clamps which are connected to the transducer arm‚ stimulation electrodes are then positioned against the muscle. I plugged the output

Exercise 9 1. A farmer wanted to find the relationship between the amount of fertilizer used and the yield of corn. He selected seven acres of his land on which he used different amounts of fertilizer to grow corn. The following table gives the amount of fertilizer (in pounds) used and the yield of corn (in bushels)for each of the seven acres. Fertilizer Used (x) 120 80 100 70 88 75 110 Yield of Corn(y) 138 112 129 96 119 104 134 a. Find the least squares regression line. a. Calculate r and r2

convenient way to find exercises and it was a great was to narrow down results for a specific muscle group or a sing muscle. This website is something I will definitely use in the future for my workouts. The website also had beneficial information on diets‚ nutrition‚ and weight management. Altogether the website was very easy to navigate and had a lot of helpful information. For the assignment I looked at and performed various exercises for a lot of different muscles.

Explain why increasing extracellular K_ reduces the net diffusion of K_ out of the neuron through the K_ leak channels. Increasing the extracellular potassium reduces the concentration gradient‚ and less potassium diffuses out of the neuron and into the cell. 2. Explain why increasing extracellular K_ causes the membrane potential to change to a less negative value.

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
