This is the result of my dominant hand having larger hand muscles due to increased use and strain i. This resulted in the numbers of pinches I made with either hand to decrease, which was anticipated due to muscle fatigue. From a scientific perspective, male are given a value of 1 and an additional 6. Or perhaps even taking heart rate measurements at 2 minute intervals to ascertain when the max heart rate is occurring to get the optimum results. This obviously means we are not reaching our peak ability to perform strenuous exercise and this is not a viable measurement of our maximum oxygen consumption.
While this experiment may provide a valuable estimation, it can be adjusted to perhaps jogging or running the 1. Also there was the bulging of my forearms veins and my arm was getting warmer and experiencing fatigue. Worksheet will open in a new window. This would allow for aerobic cellular respiration in my muscles, breaking down glucose for energy and allowing for my hand muscles to recover. The evidence of this was a burning sensation in my biceps, slower rates of curling and loss of muscle control during the strenuous exercise. Standard 4 - Performance Indicator 1. Also proper nutrition is an important component as well; the glucose gained from eating healthy foods is a vital energy source for the muscles cells and their functionality.
Production of muscle action potential-inflow of Na makes the inside of the muscle fiber more positively charged, triggering a muscle action potential 4. Therefore they might select intervals of 6 secs, 10 secs, or 20 secs and then multiple it by the appropriate factor. Walking In this experiment, we are walking instead of running. During these measured intervals, there may be fluctuations; the first 6 seconds will experience a more rapid heart than the 10-20 seconds. Yes I could tell when my muscles went into anaerobic respiration.
Power stroke-during the power stroke the crossbridge rotates, sliding the filaments 4. Males posses a much higher level of the anabolic growth hormone testosterone than females and are prone to faster muscle growth and development. Anaerobic Exercise After lifting the dumbbell, I did feel hot. Experiment 2: Power from Aerobic vs. It measures the max volume of oxygen in mm , that body cells can remove from the bloodstream in 60 seconds per kg of body mass while the body experiences max exertion.
Once my muscles had entered anaerobic respiration and required oxygen which was not readily available, I began to experience these symptoms. Some of the worksheets displayed are Muscles how muscles contract, Skeletal muscle contraction and atp demand, Muscle metabolism, Chapter 1 exercise physiology, Lesson plan muscular system 1, Unit 5, The muscular system, Respiration and photosynthesis. Muscle Fatigue And Atp Production Showing top 8 worksheets in the category - Muscle Fatigue And Atp Production. The ability for your cell to regenerate is on the decline in comparison to a younger person and is not being replaced with the same efficiency; this causes fatigue to set in faster. The non-dominant hand had a fewer number of squeezes on average than the dominant hand.
. However, as there was a brief rest between each trial, the number of squeezes for the dominant hand is more varied. This means that every 60 seconds my body is able to remove 58. Breathing deeply would result in more oxygen entering the blood stream. Once you find your worksheet, click on pop-out icon or print icon to worksheet to print or download. Formation of cross-bridges-myosin head attaches to the myhosin-binding site on actin 3. During aerobic reactions, the body was able to successful perform cellular respiration effectively, allowing for several redox reactions to transpire.
Since you are not running in this activity and not reaching your max physical peak, the results ascertained from this experiment are only an estimate. My dominant hand left had a higher number of squeezes overall during the 10 20s intervals than my recessive hand right did. They require multiple systems for digestion, respiration, reproduction, circulation, excretion, movement, coordination, and immunity. Experiment 1: Muscle Fatigue a Graphic 1: Comparison of Finger pinches over 20s intervals for both hands As the lab progressed, the strength of my fingers degraded through each successive trial. These flashcards will teach you the terms you need to succeed.
The systems interact to perform the life functions. The cells of the body are of different kinds and are grouped in ways that enhance how they function together. The results for the dominant and non-dominant hand were fairly different from each other. References Lab adapted from: Laughbaum, A. This error can be reduced by increasing the measured heart rate interval to between 20-30 seconds, if not a full 60 seconds. This prior training of my left hand allows it to perform more effectively at this task than my recessive hand, resulting in more finger pinches.
