# Does exercising before squeezing a clothespin affect the rate at which someone can squeeze the clothespin?

## Does exercising before squeezing a clothespin affect the rate at which someone can squeeze the clothespin?

Hypothesis: Exercising/Resting before you squeeze a clothespin will make you able to squeeze the clothespin more times.

How are you able to squeeze the clothespin what has to happen in your muscles?

When you were opening and closing the clothespin, your muscles were exercising anaerobically, drawing on their stores of glycogen to produce the adenosine triphosphate (ATP) molecules that supply the energy they needed to contract. If you squeeze the clothespin slowly, you’re exercising aerobically.

How many times can someone squeeze a clothespin in a minute?

My conclusion is that exercise does not affect clothespin squeezing, because the averages number the clothespin was squeezed after exercise and after rest per minute were both about 118 times.

### What does an increased pulse rate indicate about the heart rate?

— An increased pulse rate indicates an increased blood flow that carries excess carbon dioxide away from the muscle cells. — More oxygen is carried to the muscle cells.

What is the independent variable in the clothespin experiment?

(2) In an experiment to test the effect of exercise on the number of times a clothespin can be squeezed in 1 minute, the dependent variable would not be the amount of exercise. The amount of exercise is the independent variable manipulated by the researcher.

Why do muscles tire out easily?

Muscle weakness is commonly due to lack of exercise, ageing, muscle injury or pregnancy. It can also occur with long-term conditions such as diabetes or heart disease. There are many other possible causes, which include stroke, multiple sclerosis, depression, fibromyalgia and chronic fatigue syndrome (ME).

#### Why do muscles get tired ATP?

Glycolysis converts glucose to pyruvate, water and NADH, producing two molecules of ATP. Excess pyruvate is converted to lactic acid which causes muscle fatigue. Cellular respiration produces further molecules of ATP from pyruvate in the mitochondria.

How does exercise impact the number of clothespin squeezes?

If you rest first you can squeeze the clothespin more times. From the data, I collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.

Is squeezing a clothespin anaerobic or aerobic?

If you squeeze the clothespin slowly, you’re exercising aerobically. In aerobic exercise, your muscles also draw on oxygen and the glucose and fatty acids carried in by the blood to produce ATP.

## Does exercising before squeezing a clothespin?

Why are some people able to squeeze a clothespin more times in a minute than others?

Some people are able to squeeze the clothespin more times in a minute than others because they may have stronger muscles and/or a higher pain resistance. When muscles are active, cells use nutrients and oxygen at a higher rate and produce waste chemicals and heat more rapidly.

What does training to failure actually achieve?

What is the takeaway? Training to failure can be used to increase motor unit recruitment when lifting light or moderately-heavy loads, which in turn increases the likelihood that the muscle fibers attached to high-threshold motor units will grow.

### What causes muscles to tire?

The cause of muscle fatigue during intense exercise is linked directly to the muscle’s reliance on anaerobic metabolism for force production, according to a new study by researchers at Rice and Harvard universities.

Why do my muscles give out during workout?

Lactic acid is what causes muscles to burn after strenuous exercise. To really understand why riding a bicycle after playing a hockey game makes sense, let’s look closer at lactic acid. Lactic acid forms as a by-product of energy production by the muscles.
