TITLE: Electromyography (EMG) Lab: Understanding Motor Unit Recruitment INTRODUCTION: The objective of this lab is to better understand muscle contraction and the effect it has on motor unit recruitment. This lab was done in three sections, or phases, to help understand the process of muscle contraction. Phase 1 consisted of the usage of the electromyogram to measure varied levels of force that was generated by the muscle, the frequency, and the number of motor units recruited at different…

The experiment investigates a GM tube and a GM counter and the relationships of radiation. The experiment uses a GM tube to detect radiation coming from a source. This is done by the decay particle ionizing and causing the charge to build up in the tube, which is discharged and the discharge is counted by the counter and added to a display. The GM tube must be calibrated at the best voltage so that the count rate is independent of the voltage. A test was done to find this value by changing the…

Nuclear Fission Energy In nuclear plants they split the cells of uranium in a process called fission. Fission is splitting cells of atoms to create energy, this energy is important and useful because it helps power our homes and businesses. By powering our homes it helps us to do the simplest of tasks, such as; turn on the light, cook our dinner, and even charge our cellular devices. Another use if for nuclear weapons, by building and using nuclear weapons we as a country can help protect…

Proctoring: Proctoring Is the presence of a person who supervises the exam while student is taking it, and we call that person a “Proctor”, and that’s not required for all exams but only for the ones belong to “Proctored courses” that require adding a proctor whom the following conditions must be met: · He should be at least 21 years old responsible person. · He mustn’t have any problem with the compliance to the policies and procedures that UOP asks to ensure the impartiality of…

and in motion. Energy requirement to maintain the body’s condition at rest is very different than the energy requirement during maximal exercise. At rest, the muscle intake of gas is very little, but during activity, oxygen consumption is multiples due to the intense oxygen demands of the muscles. Other parameters that are expected to change during exercise are metabolic rate, heart rate and blood pressure, stroke volume, cardiac output, and total peripheral resistance. The energy required to…

The total change in energy is equal to the sum of the net reaction that is Hess’s Law the way I see it. It is important because it shows how energy is moved whether absorbed or released which is critical in science where logic and reason define all knowledge derived from the implications of science. Hess’s Law is used to determining difficult to measure energy changes such as the generation of hydrogen as a clean fuel in the example given in chem wiki (Shelly Cohen October 02 2013). It is also…

1: If 25.0 g of Al cool from 310oC to 37oC, how many joules of heat energy are lost by the Al? Heat Transfer q = m x Cs x ∆T q = C x ∆T • • • • • q = heat absorbed or released (J) Cs = specific heat (J g-1 K-1) C = heat capacity (J K-1) m = mass of substance (g) ∆T = change in temperature (K) = Tfinal -…

LAB REPORT 1 MEASURING ENERGY EXPENDITURE USING CYCLE ERGOMETER 10/13/2015 SHEETAL PARMAR TY2 INTRODUCTION Physical activity is defined as movement of body, which is produced by the skeletal muscles of the body which results in energy expenditure. There are several numbers of techniques for the assessment of physical activity related energy expend, the most valid technique to estimate this value at the definition of the physical activity is indirect calorimetry (Westerterp, 2013).…

different forms of energy and work. Not only does the thermodynamic state define volume, temperate and pressure, it will contain heat sources giving a capacity, and change state. The idea of thermodynamics is for the system to adjust itself back into its original state of an equilibrium. Through expressing the laws of thermodynamics, it is apparent that heat energy is important in the world in order to achieve ultimate equilibrium. When given a system, it is states that energy cannot be created…

Most people dread going to their jobs. They hate putting on their plain uniform, and dealing with crabby and ungrateful people, not to mention the drive to work for these people is almost as terrible as work itself. I am nothing like this. Every day before I work, I put on my athletic shorts, t-shirt, socks, and I am excited to start my job. I enjoy my drive to work, and when I get there I am greeted by a few co-workers. I then put my bags in the office, and make my way to the gym. The other…
