Some of the effects of swimming

• swimming is the only activity that doesn't increase exercising blood pressure because a swimmer's heart doesn't have to overcome gravity to pump blood to working muscles
• better than any other sport or activity, swimming increases the size of the heart's chambers, the thickness of its walls (their growth closes the holes in the heart) and the space available for it in the chest
• within one week, swimming increases blood volume up to 15 percent
• after six weeks, swimming increases the amount of hemoglobin (oxygen-carrying red blood cells) in the blood
• over time, a swimmer enhances oxygen delivery by developing more capillaries in his muscles
• swimming lowers the resting heart rate and trains the heart to recover a low heart rate quickly after hard efforts
• although it doesn't increase maximum heart rate, increased stroke volume developed through swimming improves maximum cardiac output
• swimming increases the number of mitochondria, allowing the swimmer's muscles to use more oxygen from the blood; the increased mitochondrial volume means a swimmer produces more power at a given effort
• while in the water, you will automatically do complete yogic breathing
• swimming in the ocean has very special effects on the pranic structure and the mind
