One should inhale when muscles are relaxed and exhale when initiating the lifting or push-off action in resistance training.

It is true that one should inhale when muscles are relaxed and exhale when initiating the lifting or push-off action in resistance training.

Explanation:

The reason why we have to inhale when the muscle is relaxed is that we need to oxygenate our body to perform the effort. Muscles burn energy and they need to be provided with it so they can perform the effort, as well as our whole body needs oxygen, proteins, and glucose to work support the effort. As well as to send enough oxygen to be distributed in the glucose they need to perform the duty. Also, we prepare our thoracic cave to endure the effort, gather the oxygen and burn it to perform the task.

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.
