Nutrition and Wellness Image Stretching should be part of every vigorous workout.

Fitness and exercise studies measure how much exercise and activity you need to be healthy, how much is too much, what types are best, and what risks are associated with a lack of exercise or sedentary lifestyle. Often studies in exercise incorporate elements of nutrition studies. For instance: A study might require a specific diet to create a consistent result.

When scientists study exercise, they often study walking or jogging. These exercises are easy to measure and relatively standard in terms of how people do them. In addition, they require little additional equipment, other than shoes, and, in the case of walking, are appropriate regardless of age or fitness level.

Benefits of Exercise

Exercise and fitness studies have shown the following benefits in recent years, above and beyond basic physical benefits.

Regular exercise makes you more productive, improves your mental function, and helps you to stay on task. For some people with mild to moderate depression, regular exercise may be as effective as antidepressants in treating the condition. For a 150-pound person, a 35-minute walk at a fast pace five times a week could be enough to create significant improvement in the symptoms of depression.

Sixty-two percent of adults who say they exercise or walk to help manage stress say the technique is very or extremely effective.

Physical movement reduces stress, so you feel better when you exercise. According to the American Psychological Association.

What Happens to Your Body When You Exercise?

When you warm up, blood begins to flow to your muscles. Flowing blood lubricates your joints, and your heart and lungs begin to work harder.

Stretching should be part of every vigorous workout.

When you begin an intense workout, your body has to work a lot harder and in different ways as the workout progresses. Initially, your body produces ATP using a naturally occurring amino acid called creatine. This lasts for only a few seconds. Anaerobic glycolysis allows your body to produce ATP without oxygen for about one to three minutes. This period lets your lungs catch up to your body. Aerobic glycolysis produces ATP using oxygen, glycogen stored from food, lactic acid, and stored fat. This is the method by which most activity, from a long walk to a marathon, is fueled.

What Kind of Exercise Is Best?

Exercise is typically divided into two categories:

  1. Aerobic exercise is exercise that increases your heart rate and works your heart and lungs.
  2. Strength training is exercise that works specifically to make your muscles stronger.

Swimming: Swimming is ideal for anyone with joint issues. The buoyancy of the water allows for an aerobic workout without putting weight on the joints, thus reducing the strain on knees, ankles, hips, shoulders, and elbows.

Body-weight exercises: These exercises involve lifting your own body weight and using it as resistance. They are one of the best choices for strength training. These exercises don't take additional equipment, can be done anywhere, and can be modified to accommodate physical disabilities or special needs.
