Total Energy Cost Laboratory
Introduction:
There are three energy systems that produce ATP. First is the ATP-PC system (high power and short duration), Glycolytic System (moderate power and moderate duration), and the oxidative aerobic system (low power and long duration). In this lab, a subject weight lifted for one minute. At the start, the Phosphagen system immediately took place. This system, also called the ATP-PC system is the quickest way to re-synthesize ATP, and is a rapid supply of energy. This process occurs withing the first 6 seconds of intense exercise, and is an anaerobic component due to the absence of oxygen.
After this short burst, the glycolytic system kicks in. During the glycolytic system, glucose is broken down to create …show more content…
A student from the class was chosen as the subject. Requirements for this lab are as follows, the subject must weight lift at a steady state for one minute at a relatively difficult weight for them. The subject was a 21 year old female, who lifted 20 reps at 50 pounds for one minute. Blood lactate was measured after the 5 minute mark of recovery. The blood lactate measured at 4.7 mmols. Blood lactate measurements are used to determine the lactate threshold, as well as determining the correct intensity of exercise for the individual.
The steps in setting up the metabolic cart and lab are as follows,
1. Turn on the metabolic cart. It takes approx. 30 min to warm up.
2. Calibrate the metabolic cart. Gas calibration followed by flow-meter calibration.
3. 3 variable must be entered into the system for calibration accuracy: temperature, barometric pressure, and relative humidity.
4. The subject must thoroughly wash their hands prior to the lab, because lactate ca reside on the hands from sweat.
5. The subject wore a mask that was connected to the metabolic cart, which receives data.
6. The subject lays resting for 2 minutes, and then begins one minute of steady state lifting at 50
