Why Exercise Works

Why Exercise works

Why Exercise WorksBuilding lean muscle and getting the heart pumping blood to your entire body are just a couple of the most commonly known benefits of exercise. Being in good physical and mental shape is even more crucial when you are dealing with a disease that has taken so many lives. For the person dealing with a cancer diagnosis, such as mesothelioma, getting regular exercise has the potential to help in a plethora of ways.

Below is a list of some of the benefits that come with regular exercise:

Reducing your stress – With as little as 30 minutes of activity per day, you can see an increase in serotonin and dopamine levels. These are chemicals that will help to sooth and calm you. There can be no doubting that having cancer can cause stress, exercising is a natural way to alleviate that stress. Those “feel good” chemicals provide an atmosphere where stress won’t be able to flourish so easily.

Naturally lift depression – Exercise has often been referred to as a natural antidepressant. If you are person who finds yourself fighting depression and is having trouble keeping your spirits up, being active can help without any medication. When you already have to take medicine to treat your cancer, regular exercise is a good way to fight off depression without needing to take any
additional medication.

Keeps your body strong – As your doctor works hard to kill the cancer attacking your body, staying active through exercise is a great way to work on offsetting the damage being done to your body. Exercise works to keep the body as well as the mind strong. You can build lean muscle, increase the oxygen levels in your blood and improve your memory; it will help you to put the focus on remaining strong in the body and mind – something you need when you’re waging a war against cancer.

Imagine waking up one day knowing you have to receive mesothelioma treatment before that day ends. There is nothing you can do about the cancer or that you must deal with whatever side effects come with receiving such treatment. Now imagine starting that same day out by going for a brisk walk in your neighborhood; you walk for 30 minutes working up a sweat and admiring the beauty of nature. At the end of the exercise session, how much better prepared do you think you’d be for your mesothelioma treatment? Probably a lot!

Making a commitment to take care of your body when you are diagnosed with cancer is about more than just keeping fit. This is about doing what you can to increase your quality of life, even when that life includes a fight with cancer. Your energy will levels with rise, your attitude will become more positive and you can feel good about doing your part to live a happy and healthy life for many more years to come.

Redox Signaling Powers Up Aerobic Performance

As the energy requirements of the cells and tissues increase during aerobic activity, oxygen and sugars in the blood must be able to be transferred from the lungs and energy stores into the muscle cells and tissues. Waste products like CO2 and excess lactates must be transferred out of the cells and tissues and back into the blood and out of the body. The efficiency at which the cells can move oxgen fuel and waste products back and forth through the blood and cellular membranes determines how long the body can sustain aerobic activity.

When the oxygen and energy demands of the muscle tissues exceed the ability of the body to maintain adequate delivery, the muscle cells and tissues start to burn internal energy stores anaerobically (without the use of oxygen), waste products (CO2 and lactates) start to build up and further interfere with the aerobic processes. When the internal energy stores of the muscle cells are exhausted, no more energy can be provided and muscle activity ceases completely.

Increasing the amount of balanced redox signaling molecules in the body helps normalize the redox potential in and around the cells and tissues. A balanced redox potential in the tissues increases the efficiency at which oxygen, fuels and wastes can be transferred in and out of cells and tissues, making the natural aerobic processes more efficient. If aerobic capacities are increased, then the natural length of time that aerobic activity can be sustained under high energy demands is also increased. The time that it takes to recover normal aerobic balance after an intense anaerobic effort is also shortened.
