When muscles are subjected to long periods of vigorous activity, they undergo fatigue due to the depletion of energy stores, accumulation of metabolic byproducts like lactic acid, and reduced oxygen availability. This can lead to decreased muscle performance, cramping, and soreness. Over time, with proper recovery and training, muscles can adapt by increasing strength, endurance, and efficiency. However, prolonged intense activity without adequate rest can result in injury or overtraining.
Vigorous!! :]

The body takes in oxygen for the muscles to use, but if exercise is vigorous enough, anaerobic respiration takes over and can build up lactate (lactic acid) in the muscles and bloodstream. This must eventually be oxidized, and any oxygen taken from other tissues must be replaced. This state is called "oxygen debt" and recuperation may be delayed by continued exertion (as in sports) rather than rest.Normally recovery is short, requiring a few minutes of rest. Longer periods of continuous exercise can require longer periods of recuperation.
Rich stores of glycogen can be found in the liver and muscles. The liver stores glycogen to regulate blood sugar levels and provide energy during fasting periods, while muscles store glycogen to use as a source of fuel during physical activity.
The info that you need to know about periods is that you will require a tampon if you are having periods and you want to engage in an activity such as swimming.
periods
The production of heat by muscles helps regulate the body's temperature by generating warmth that can counteract heat loss. This process, known as thermogenesis, helps maintain a stable internal temperature, especially during periods of cold or physical activity.
