Why walk is necessary? Ever questioned what materialises after walking? Here’s a minute-by -minute neglected of the amazing chain reaction walking and exercise, it’s really remarkable!
Minutes 1 to 5
Initial few steps generate and discharge of energy-producing chemicals in body cells to fuel walk. Heart rate revs-up from 70 to 100 beats per minute (bpm), enhancing blood-flow and warming up muscles.
Any toughness dwindles as joints discharge lubricating fluid to aid movement more easily. As you get moving, body burns 5 calories per minute, compared with only 1 per minute at rest. Body wants more fuel and starts pulling from its carbohydrates and fat stores.
Minutes 6 to 10
Heartbeat upsurges and it also burns up to 6 calories a minute as one pick up the speed. A trivial rise in blood pressure is defied by the release of chemicals that expand blood vessels, giving more blood and oxygen to working muscles.
Minutes 11 to 20
Body temperature keeps rising, and one start to sweat as blood vessels near the skin expand to release heat. As walk becomes brisker, person will be using up to 7 calories a minute and breathing firmer. Hormones such as epinephrine and glucagon increase to discharge fuel to the muscles.
Minutes 21 to 45
Feeling revitalised, person starts to relax as body releases tension, thanks in part to a dose of feel-good chemicals such as endorphins in brain. As more fat is burned, insulin (which helps store fat) drops — excellent news for anyone battling excess weight or diabetes.
Minutes 46 to 60
Muscles may feel fatigued as carbohydrates stores are reduced. As you cool down, heart rate decreases and breathing slows. One will be using fewer calories but more than before one started. Calorie burn will remain elevated for up to 1 hour.
All this happens without a single conscious thought from us – the human body is amazing.
