List down any four effects of exercise on the muscular system.

The muscular system consists of various types of muscle that each play a crucial role in the function of the body. Muscles allow a person to move, speak, and chew. They control heartbeat, breathing, and digestion. Other seemingly unrelated functions, including temperature regulation and vision, also rely on the muscular system. Keep reading to discover much more about the muscular system and how it controls the body. Share on Pinterest The muscles account for around 40 percent of a person’s weight with the largest muscle in the body being the gluteus maximus in the buttocks. The muscular system contains There are 3 types of muscles in the body: Skeletal muscle Skeletal muscles are the only muscles that can be consciously controlled. They are attached to bones, and contracting the muscles causes movement of those bones. Any action that a person consciously undertakes involves the use of skeletal muscles. Examples of such activities include running, chewing, and writing. Smooth muscle Smooth muscle lines the inside of blood vessels and organs, such as the stomach, and is also known as visceral muscle. It is the weakest type of muscle but has an essential role in moving food along the digestive tract and maintaining blood circulation through the blood vessels. Smooth muscle acts involuntarily and cannot be consciously controlled. Cardiac muscle Located only in the heart, cardiac muscle pumps blood around the body. Cardiac muscle stimulates its own contractions that form our h...

During aerobic activity, you repeatedly move large muscles in your arms, legs and hips. You'll notice your body's responses quickly. You'll breathe faster and more deeply. This maximizes the amount of oxygen in your blood. Your heart will beat faster, which increases blood flow to your muscles and back to your lungs. No matter your age, weight or athletic ability, aerobic activity is good for you. Aerobic activity has many health benefits. As your body adapts to regular aerobic exercise, you'll get stronger and fitter. Consider the following 10 ways that aerobic activity can help you feel better and enjoy life to the fullest. Aerobic activity can help you: 1. Keep excess pounds at bay Combined with a healthy diet, aerobic exercise helps you lose weight and keep it off. 2. Increase your stamina, fitness and strength You may feel tired when you first start regular aerobic exercise. But over the long term, you'll enjoy increased stamina and reduced fatigue. You can also gain increased heart and lung fitness and bone and muscle strength over time. 3. Ward off viral illnesses Aerobic exercise activates your immune system in a good way. This may leave you less susceptible to viral illnesses, such as colds and the flu. 4. Reduce your health risks Aerobic exercise reduces the risk of many conditions. These conditions include obesity, heart disease, high blood pressure, type 2 diabetes, metabolic syndrome, stroke and certain types of cancer. Weight-bearing aerobic exercises, such a...

\( \newcommand\) • • • • • • • • Key Points • Aerobic exercise, or physical activity under conditions of high oxygen availability, involves extended periods of exercise at levels below maximal contraction strength, and uses a high percentage of Type I muscle fibers. • Anaerobic respiration, or physical activity with a low availability of oxygen, involves high intensity muscle contractions for short periods of time, utilizing primarily Type II muscle fibers. • Anaerobic exercise involves short, high-intensity bouts of exertion that utilize little or no oxygen and lead to increased levels of lactic acid. • Muscle metabolism differs due to exercise type, primarily the availability (aerobic) or lack of availability (anaerobic) of oxygen. The rate at which energy is needed determines the relative contributions of these energy systems. • Muscle metabolism differs due to exercise type, primarily the availability (aerobic) of lack of availability (anaerobic) of oxygen. Glossary muscle hypertrophy: Increase in muscle mass due to exercise, particularly weight training; a noticeable long-term effect of exercise. lactic acid: Also known as milk acid, is a chemical compound that plays a role in various biochemical processes. During power exercises such as sprinting, when the rate of demand for energy is high, glucose is broken down and oxidized to pyruvate, and lactate is produced from the pyruvate faster than the tissues can remove it, so lactate concentration begins to rise. Type II ...

Immediate effects of exercise on the body systems When a person takes part in exercise the cardiovascular, respiratory, energy and muscular systems all work together to supply energy to the working muscles and remove waste products. When the muscles start to work, they need more oxygen so the respiratory system responds by getting more oxygen into the lungs. The blood carries greater amounts of oxygen and the heart responds to pump more oxygenated blood around the body. Immediate effects can be visible in hot, sweaty and red skin. Immediate effects of exercise on the body systems are shown in the table: Short term effects of exercise Cardiovascular system Increase in stroke volume (SV); increase in heart rate (HR); increase in cardiac output (Q); increase in blood pressure (BP) Respiratory system Increase in breathing rate; increase in tidal volume Cardio-respiratory system Increase in oxygen uptake; increase in carbon dioxide removal Energy system Increase in lactate production Muscular system Increase in temperature of muscles; increased pliability After exercising, the muscles need to rest, adapt and recover. There is a risk of injury if the body is not rested for long enough after exercise. This concept can be better understood by studying the Principles of training . Question Why is a person less likely to strain a muscle if they have warmed up before taking part in exercise? Reveal answer

Long term effects of exercise on the body systems Taking part in regular exercise or training around three times per week for six weeks will lead to adaptation of the body systems that are used or trained. This has the effect of increasing performance in that type of exercise or sport and is often beneficial to general health and everyday life. Aerobic training increases aerobic endurance Long term effects of exercise Type of training Cardiovascular system Cardiac hypertrophy; increased stroke volume (SV) at rest and during exercise; decrease in resting heart rate (HR); increase in cardiac output (Q); capillarisation at the lungs and muscles; increase in number of red blood cells Aerobic activities (lower intensity, longer duration) produce these effects most Respiratory system Increased tidal volume (TV), minute ventilation (TE) and vital capacity; increased number of functioning alveoli; increased strength of the respiratory muscles (intercostals and diaphragm) Aerobic activities (lower intensity, longer duration) produce these effects most Energy system Increased production of energy from the aerobic energy system; increased tolerance to lactic acid; faster recovery rate; increased aerobic capacity Aerobic activities/training; anaerobic training; general effect Muscular system Muscle hypertrophy; increased strength of tendons and ligaments; increased muscular strength; increased muscular endurance; increased speed of contraction; increased resistance to fatigue Resistan...

Question: List down any four effects of exercise on the muscular system? Regular exercise has several positive effects on the muscular system. Firstly, it increases muscle strength and endurance by stimulating the growth of muscle fibers and improving their ability to use oxygen efficiently. Secondly, exercise can help prevent muscle atrophy or loss of muscle tissue, which can occur with age or inactivity. Thirdly, exercise promotes improved flexibility and range of motion, reducing the risk of muscle strain or injury. Finally, exercise can also stimulate the release of endorphins, providing a natural mood boost and reducing stress on the muscular system.
