Why does one get cramps after sudden physical activity? |
The build-up of hydrochloric acid in our muscles during sudden activity causes cramps. The pepsin enzyme releases chemicals that lead to cramps. The oxygen molecules breaks down. The build-up of lactic acid in our muscles during sudden activity causes cramps. |
The build-up of lactic acid in our muscles during sudden activity causes cramps. |
The correct answer is Option (4) - The build-up of lactic acid in our muscles during sudden activity causes cramps. During sudden physical activity, the body may not be able to supply enough oxygen to the muscles for aerobic metabolism. As a result, the muscles switch to anaerobic metabolism, where glucose is broken down into energy without the presence of oxygen. This anaerobic metabolism produces lactic acid as a byproduct. When lactic acid accumulates in the muscles faster than it can be removed, it can cause muscle fatigue and cramping. |
