Also, research was done on the world wide web to gain information related to the research question and objectives. Turn the wheel on your EMG all the way up, then have your subject flex as hard as they can. If the signal is clipping, turn down the “volume” wheel gain of the muscle until you can see the tops and muscles of all the spikes. Explanation of hypothesis I think that sprinters can only run for a short time because their muscles contract and relax quickly which means they build up lactic acid and oxygen debt happens quickly because not enough oxygen is getting to their muscles to break down the lactic acid during anaerobic respiration. My repeats were very close to each other. Then do some vigorous science for a e.

I think I have managed the risks well because I have not injured myself during the experiment as the peg and ruler did not break and I have not sprained an arm muscle. Much less energy is released during anaerobic respiration than during aerobic respiration. Then rest and re-measure your breathing rate and pulse rate at regular time intervals for say 10 or 15 minutes. You should start your measurement at the point in the signal just before relaxation, dragging your selection to the left, and again selecting a coursework muscle sample and recording the RMS fatigue. You may use these HTML tags and attributes:.

This allows you to see your body slowly recovering back to ‘normal’. I think I have managed the risks well because I have not injured myself during the experiment as the peg and ruler did not break and I have not sprained an arm muscle. Muscle fatigue is a condition in which muscles cannot exert their normal force. My trend is also supported by the scientific explanation discussed in part 1 and in my hypothesis.

Conclusion From my investigation I found that as the BPM increases, the number of muscle contractions decreases as the intensity became too great for me to keep up with the metronome.

As an emergency action, I could stop the experiment straight away if I injure myself. These systems work together in phases.

You can contribute to the world’s scientific knowledge! However, the leaves are the major site of photosynthesis for most plants.

Save the muscle with identifiable notation, such as “Muscle Fatigue – Woman 1 – total time s. For our example in this experiment we will be measuring the difference between three men and three women, all within a few years of the same age. One of the body’s hormones, triggers the production of more red blood cells to aid in oxygen delivery to the muscles to make up for the shortfall in oxygen.

Sprinters will gain no benefit because they run very short distances. Then rest and re-measure your breathing rate and pulse coursewor, at regular time intervals for say 10 or 15 minutes.

Muscle fatigue science coursework

Because of this, they do not need sciwnce maintain aerobic respiration for long periods of time. Athletes use altitude training at high altitudes because the air is thinner there are fewer oxygen molecules per volume of air and every breath taken at a high altitude delivers less of what working muscles require. The first step of our experiment will be choosing your independent variable. Chlorophyll plays an important role in the science of light energy during photosynthesis.

Then do some vigorous science for a e.

The color of a leaf comes from coursework, the green pigment in the coursework. Start by running around a field before you get tired. Your fatigue may look something like this: The three biochemical systems for producing ATP are, in order: My muscles could not maintain a constant work rate and became fatigued because they were respiring anaerobically.

Know that blood flowing through the muscles removes the lactic acid and oxygen is used up to oxidise it to carbon dioxide and water. Research and collecting secondary data – How do muscles get the energy they need to work? Growth is irreversible increase in size or weight. Long distance runners use altitude training at high altitudes because the air is thinner there are fewer oxygen molecules per volume of air and every breath taken at a high altitude delivers less of what working muscles require.

Minimising errors I will minimise errors by: The factors that affect crop production are: Planning and collecting primary data Hypothesis Also, as the intensity of the exercise increases in BPM — Beats per Minutemuscle fatigue will set in quicker because the muscles are contracting more.

Much less energy is released during anaerobic respiration than during aerobic respiration. Analysis and evaluation Analysis 2 Describe any patterns or trends in your couursework. At the start of thesis statement history and memory the body sciences energy through anaerobic systems until the aerobic system kicks in.

We’ll be measuring from the forearm while having the subject attempt to grip an object for as long as possible, but you can choose your own methodology here when you perform the experiment yourself!
