Clothespin
Effect of Exercise on Muscle Fatigue
Question:
Does exercise such as jumping jacks effect muscle fatigue?
Hypothesis:
This experiment tests the effect of exercise (jumping jacks) on muscle fatigue of the body. Exercise will make a person squeeze a clothespin fewer times in one minute compared to the person not exercising because exercising takes away a muscle’s energy. Therefore a resting person will have more energy for the clothespin squeezing.
Methods and Materials:
Materials for this experiment include a stopwatch and a clothespin. The procedures of this experiment are to be carried out as follows:
1. Facilitator tells participant, “You are to squeeze the clothespin as many times as you can for 1 minute using only your index finger and thumb. As you squeeze the clothespin, count how many times you are able to. With 10 seconds remaining, you will receive a warning.”
2. Allow participant to begin when facilitators starts the stopwatch and says “Begin.” At 50 seconds, the facilitator must provide the 10 second warning saying, “You have 10 seconds remaining.”
3. At the end of the minute, the facilitator will take the clothespin, record the number of clothespin squeezes, and wait 20 seconds.
4. At 20 seconds, the participant will do 30 jumping jacks.
5. After the 30 jumping jacks, the facilitator will give the clothespin back to the participant and will start the one minute timer.
6. Repeat steps 2 and 3 In this experiment, controlled variables include using the same clothespin, using the index finger and thumb to hold the clothespin, and all participants receiving the “10 second” warning. The independent variable of the experiment is the jumping jacks performed by the participant. The dependent variable of the experiment is the number of squeezes of the clothespin in one minute.
Data Collected:
The data that was collected from this experiment does support the hypothesis. The hypothesis states that the participant will squeeze the
