The physical benefits of exercise — improving physical condition and fighting disease — have long been established, and physicians always encourage staying physically active. Exercise is also considered vital for maintaining mental fitness, and it can reduce stress. Studies show that it is very effective at reducing fatigue, improving alertness and concentration, and at enhancing overall cognitive function. This can be especially helpful when stress has depleted your energy or ability to concentrate.
When stress affects the brain, with its many nerve connections, the rest of the body feels the impact as well. Or, if your body feels better, so does your mind. Exercise and other physical activity produce endorphins — chemicals in the brain that act as natural painkillers — and also improve the ability to sleep, which in turn reduces stress.
Scientists have found that regular participation in aerobic exercise has been shown to decrease overall levels of tension, elevate and stabilize mood, improve sleep, and improve self-esteem. About five minutes of aerobic exercise can begin to stimulate anti-anxiety effects.
The usage of physical exercise in conjunction with BrainHQ brain training increases your chances of increasing cognitive functions within parameters, including time of exercise and style of exercise. Interestingly, differences between exercise styles, such as opting for cycling over running, is associated with an enhanced brain function during and after working out. Ballroom dancing, an activity with both physical and mental demands has had a higher impact on cognitive functioning over exercise or mental tasks alone, indicating that the best brain health workouts involve those that integrate different parts of the brain such as coordination, rhythm, and strategy. Tips for Choosing The Right Physical Exercise -In general, anything that is good for your heart is great for your brain. -Aerobic exercise is great for body and brain: not only does it improve brain function, but it also acts as a “first aid kit” on damaged brain cells. -Exercising in the morning before going to work not only spikes brain activity and prepares you for mental stresses for the rest of the day, but also produces increases retention of new information, and better reaction to complex situations. -When looking to change up your work out, look for an activity that incorporates coordination along with cardiovascular exercise, such as a dance class. -If you like crunching time at the gym alone, opt for circuit work outs, which both quickly spike your heart rate, but also constantly redirect your attention. -Hitting a wall or mentally exhausted? Doing a few jumping jacks might reboot your brain.
For most healthy adults, the Department of Health and Human Services recommends these exercise guidelines: -Aerobic activity. Get at least 150 minutes a week of moderate aerobic activity or 75 minutes a week of vigorous aerobic activity. You also can do a combination of moderate and vigorous activity. The guidelines suggest that you spread out this exercise during the course of a week. -Strength training. Do strength training exercises at least twice a week. No specific amount of time for each strength training session is included in the guidelines. Moderate aerobic exercise includes such activities as brisk walking, swimming and mowing the lawn. Vigorous aerobic exercise includes such activities as running and aerobic dancing. Strength training can include use of weight machines or activities such as rock climbing or heavy gardening. As a general goal, aim for at least 30 minutes of physical activity every day. If you want to lose weight or meet specific fitness goals, you may need to exercise more. Want to aim even higher? You can achieve more health benefits, including increased weight loss, if you ramp up your exercise to 300 minutes a week. Short on long chunks of time? Even brief bouts of activity offer benefits. For instance, if you can’t fit in one 30-minute walk, try three 10-minute walks instead. What’s most important is making regular physical activity part of your lifestyle.
Imagine that you’re exercising. You’re working up a sweat, you’re breathing hard, your heart is thumping, blood is coursing through your vessels to deliver oxygen to the muscles to keep you moving, and you sustain the activity for more than just a few minutes. That’s aerobic exercise (also known as “cardio” in gym lingo); any activity that you can sustain for more than just a few minutes while your heart, lungs, and muscles work overtime. The beginning. It all starts with breathing. The average healthy adult inhales and exhales about 7 to 8 liters of air per minute. Once you fill your lungs, the oxygen in the air (air contains approximately 20% oxygen) is filtered through small branches of tubes (called bronchioles) until it reaches the alveoli. The alveoli are microscopic sacs where oxygen diffuses (enters) into the blood. From there, it’s a beeline direct to the heart. Getting to the heart of it. The heart has four chambers that fill with blood and pump blood (two atria and two ventricles) and some very active coronary arteries. Because of all this action, the heart needs a fresh supply of oxygen, and as you just learned, the lungs provide it. Once the heart uses what it needs, it pumps the blood, the oxygen, and other nutrients out through the large left ventricle and through the circulatory system to all the organs, muscles, and tissues that need it. A whole lot of pumping going on. Your heart beats approximately 60-80 times per minute at rest, 100,000 times a day, more than 30 million times per year, and about 2.5 billion times in a 70-year lifetime! Every beat of your heart sends a volume of blood (called stroke volume — more about that later), along with oxygen and many other life-sustaining nutrients, circulating through your body. The average healthy adult heart pumps about 5 liters of blood per minute. Oxygen consumption and muscles. All that oxygen being pumped by the blood is important. Muscles are like engines that run on fuel (just like an automobile that runs on fuel); only our muscles use fat and carbohydrates instead of gasoline. Oxygen is a key player because, once inside the muscle, it’s used to burn fat and carbohydrate for fuel to keep our engines running. The more efficient our muscles are at consuming oxygen, the more fuel we can burn, the more fit we are, and the longer we can exercise.
