Diving workout

[davisj]

No matter what type of exercising one intends to do ( cardio, weights ),..Some is better than none !

When a body increases exercise level, it responds in many ways. The most noticable are increases in heart and breating rates. The reason for these icreases can be found on the cellular level. Oxygen is required for all cells in the body to do any amount of work. When the workload of the cells increases their oxygen needs increase as well. The body responds by increasing the blood flow to the cells ( increase in heart rate ), and maintaining the oxygen content of the blood ( increase in resparation ). If the need for oxygen is sustained, the vascular system ( arteries and veins ) will respond by increasing their diameter, allowing even more blood and oxygen delivered to the cells.

If exercise is repeated, pulmonary ( lung ), cardio ( heart ), and vascular systems will become stronger, larger, and more efficient. What does this mean for diving ?

Improved cardiovascular fitness will result in ...Lower gas consumption rates ! More bottom time ;D

Increased lung function from exercise will improve gas exchange. Better O2 delivery to the cells, better elimination of CO2 from the cells( which contributes to Oxygen Tox and Nitrogen Narc ), and improved removal of Nitrogen during decompression.

So even if it takes a few long walks, some exercise is better than none!
