Introduction[edit | edit source] Show
Aerobic exercise refers to the type of repetitive, structured physical activity that requires the body’s metabolic system to use oxygen to produce energy. Aerobic exercise:
Effects of aerobic exercises[edit | edit source][2] Aerobic exercises mainly shows an effect in health-related components of fitness especially cardiovascular endurance and body composition. For neuromuscular adaptation following aerobic exercises click link. Physiological effects of aerobic exercises are explained below:[3]
These effects helps in following benefits to the body:[5][6]
How Much?[edit | edit source]Healthy adults should aim for at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous aerobic activity a week, or an equivalent combination of moderate and vigorous activity. That doesn't have to be all at one time, though. For example, brisk walking for 30 minutes, five days a week meets the guidelines. Aerobic exercise can even be done in short blocks of time, such as several walk breaks spread throughout the day. Any activity is better than none at all[7]. Criterion measures[edit | edit source]Why perform exercise tests?
Standard graded exercise tests are used clinically to assess a patient’s ability to tolerate increasing intensities of aerobic exercise Eg:
These tests help to identify the criterion measures for cardiovascular fitness and exercise capacity.[9]
Evidences[edit | edit source]American College of Sports and Medicine (ACSM), 2014 has prescribed aerobic exercises based on FITT ( frequency, intensity, time, type) in different conditions and age groups.[9] Cardiovascular Disease/ Risk factors and Aerobic Exercise Cardiovascular diseases (CVDs) are the number one cause of death globally, taking an estimated 17.9 million lives each year. Out of many cardiovascular diseases, heart attack and stroke being the most common cause of death. Lifestyle modification is the first line of treatment suggested by WHO and American heart association which includes diet and exercise.[11] Supervised cardiac rehabilitation protocols are there to guide the treatment. A randomized controlled trial done in 2019, has shown benefits of combined training (aerobic 30 minutes/session plus resistance 30 minutes/session) 3 days/week for 8 week rather than aerobic exercise and strength exercise alone. Combined training provided significant reductions in peripheral (-4 mmHg) and central diastolic BP (-4 mmHg), increase in CRF (4.9 ml/kg/min), increase in upper (4 kg) and lower (11 kg) body strength, and increase in lean body mass (0.8 kg).[12] Diabetes and Aerobic Exercise Supervised exercise interventions improve glycated hemoglobin (A1C), triglycerides (TG), and cholesterol (9) in people with type 2 diabetes. Both aerobic and resistance exercise are beneficial, and it is optimal to do both types of exercise. At least 150 minutes per week of aerobic exercise and at least 2 sessions per week of resistance exercise are recommended.[13] It is very important to maintain the dose of insulin and time of exercise and also carbohydrate intake during and after exercise to prevent post-exercise hypoglycemia. For detail please have a look at this guideline.[13] Chronic pain and Aerobic Exercises Aerobic exercise programs have shown physiological, psychological, and articular benefits in patients with chronic diseases (e.g., arthritis, osteoarthritis, and fibromyalgia). Aerobic exercise stimulates the release of endorphins that relieve pain by inhibiting the pain pathways. It makes the patient more active, reducing the fear of moving (kinesiophobia) and increasing self-confidence. A systematic review protocol published in 2019 has shown the effect of aerobic exercise and chronic non- specific low back pain. Aerobic exercise with a duration of 15 to 60 continuous minutes and intensity of 60 to 90% of the maximum heart rate had shown significant improvement. Mental health and Aerobic Exercise: In the systematic review and meta-analysis done in 2019 across 11 eligible trials (13 comparisons) involving 455 patients, aerobic exercise delivered for an average of 45 minutes, at moderate intensity, three times/week, for 9.2 weeks and showed a significantly large overall antidepressant effect.[14] Pregnancy and Aerobics: Low impact aerobic exercises are the key to physiological as well as psychological well-being during pregnancy. Regular, low-impact aerobic exercise during pregnancy will help to strengthen heart and lungs, to tone muscles, ease pregnancy aches and pains and allows a better night's sleep. alternatively it will help to cope with the demands of pregnancy and birth.[15] A Cochrane systemic review has shown that Regular aerobic exercise during pregnancy appears to improve (or maintain) physical fitness.[16] A meta-analysis of 9 RCTs that included 2059 women with an uncomplicated, singleton pregnancy with normal body mass index showed that women who were assigned randomly to aerobic exercise had similar incidence of PTB, lower incidences of GDM, GHTN disorders, cesarean delivery, and a higher rate of vaginal delivery.[17] Risk of Fall in Elderly and Aerobics: As the age advances there are various physiological changes occur in the body, hence muscle strength reduces more in lower extremity than the upper extremity, increases the risk of fall in geriatric population. Aerobic exercises has shown improvement in balance and gait.[18] Children and Aerobics: According to the latest guidelines children from age 3 to 5, need to be active throughout the day to improve growth and development. Children of this age group should aim for at least 3 hours a day of physical activities, they must be active throughout the day.[19][20] Children and adolescents ages 6 through 17 years should do 60 minutes (1 hour) or more of moderate-to-vigorous physical activity daily.60 minutes of physical activities involving aerobics such as running, walking, swimming and cycling is highly encouraged for overall growth as an individual.[21][22] Resources[edit | edit source]

What type of rhythmic exercise uses large muscle groups continuously?Aerobic exercise uses continuous, rhythmic movement of large muscle groups to strengthen the heart and lungs (cardiovascular system).
What do you call the aerobic movements that involve large muscle groups used in a continuous rhythmic activity?Activity in which the body's large muscles move in a rhythmic manner for a sustained period of time. Aerobic activity – also called endurance activity – improves cardiorespiratory fitness. Examples include walking, running, and swimming, and bicycling (34).
What is the type of exercise that involves large muscle groups with continuous movement over long periods of time in order to improve aerobic capacity?Aerobic exercises are typically moderate-intensity exercises involving larger muscle groups that are performed over extended periods to improve cardiovascular function. Examples of aerobic exercise include walking, cycling, and pool exercises.
What are the large primary muscle group for aerobic exercise?Rhythmic Use of Muscle Groups
When fitness experts refer to using your large muscle groups, they are speaking of the muscles in your arms, chest, legs, torso and hips -- such as your biceps, pectorals, quadriceps, abdominals and gluteus maximus. Basically, in aerobic exercise, you move your whole body.
