What is fitness? What are the components of fitness?
These questions come in mind for a hundred of people who want to become fit. According to ordinary people, fitness is the state of having a good-looking and being flexible. But, oxford dictionary define it as The quality of being suitable to fulfil a particular role or task. However, fitness have various components, which improve the body such as, cardiorespiratory system, muscular strength and endurance, and flexibility
The first components, Cardiorespiratory system is pertaining to the heart and lung function to the body. is defined as the ability of the cardiac system to provide oxygen to the working muscles. This includes the ability of the lungs to

Additionally, It has two components include muscular strength and endurance. According to the American Council on Exercise (ACE), muscular strength is the maximal force a muscle or muscle group can exert during an activity. Muscular endurance is the ability of a muscle to resist repeated contractions against an impedance for an extensive period. However, inside the muscular, there are muscular tissue, which help to improve the strength of the muscles, and it has two types, which include fast twitch and slow twitch fibers. Fast twitch fibers have a large size, high strength and fit …show more content…
Moreover, there are special types of exercise that improve the flexibility: Dynamic exercise, the ability to perform movements on the full term of the joint dynamically, and it work by performing a certain situation which similar to the static flexibility but with the continuation of the performance of kinetic movements in the direction of increasing the extent of the contraction of the muscles core. Static-active exercise, maintaining the body status in steady position for a period. Ballistic exercise, this type of exercise happen when the body is warmed up to move beyond its normal range it might be dangerous if the muscle is not prepared to
The four different type of fiber types are: slow, fast and fatigue resistant, fast fatigable and fast intermediate. Slow muscle fibers have a long twitch time, which means that they have low peak forces, and have a high resistance to fatigue. These fibers are high in oxidative enzymes and are low in glycolytic markers and ATP activity.
As we have learned through our reading, most all bodies skeletal muscles are made up of primarily three types of skeletal muscle fibers, but their proportion differs depending on what action the muscles is doing. For example, type I fibers such as muscles of the neck, back, and leg have a higher proportion. According to Quinn (2014), type I muscles are slower and more effective, they tend fire a lot slower than fast twitch fibers and they fatigue at a much slower rate. Hence, slower twitch fibers are pronounced at helping athletes run marathons and bicycle for hours. Shoulder and arm muscles are not always active but are intermittent in their use; these muscles tend to have a larger amount of tension for uses in throwing and lifting. These muscles have a combination of both type I and type II B fibers. These fast twitch fibers use anaerobic metabolism to create energy and are the "classic" fast twitch muscle fibers that excel at producing quick, powerful bursts of speed. These muscles are used in events such as 100m sprint, basketball, soccer and football. Since this muscle fiber fires at such a high rate of contraction it will fatigue much faster and will not last long before needing to rest.
The cardiovascular system - The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. It consists of the heart, which powers the whole process, the veins, arteries, and capillaries, which deliver oxygen to tissue at the cellular level. The cardiovascular system carries blood that is low in oxygen away from the heart to the lungs via arteries, where oxygen levels are restored through the air once oxygenated, this blood is then carried throughout the body via arteries, keeping our organs and tissue alive. The cardiovascular system is the workhorse of the body, continuously moving to push blood to the cells. If this important system ceases its work, the body dies.
There are different types of muscle because each sport has various needs. “Power endurance is typically characterized by intense, repeated efforts for a relatively short period of time (less than 30 seconds)”(1). Sports such as sprinters, wrestlers, fencers and tennis players need to produce powerful movements and repeat them with several times with little to no rest. This training involves lifting about 15-30 reputations of moderate loads, about 50%-70% 1RM per lift.
Trans theoretical Model is a health model that focuses on the individual who is ready to create new healthier habits. The theory has been widely used by the health professional to treat health behaviors such as smoking cessation, eating disorder, and physical activity. According to the process of change, an individual who received appropriate intervention is most likely to become successful. There are five stages including contemplation, contemplation, preparation, action, maintenance, and termination. Pre-contemplation is where the individual has no intention to change a health behavior. Contemplation occurs if the individual thinks about moving forward, but does not exactly know where to begin. A preparation occurs where the individual who
Kerr (2012) states that there are 3 main types of exercise which are aerobic, strength/resistance training and flexibility exercises. Aerobic exercises will help keep the heart, lungs and muscles healthy, and when paired with a healthy diet will aid in weight loss. Appropriate resistance training will help to improve strength, posture and balance as well as causing the participant’s body to look more toned. Also the build up of muscle will aid with weight loss as at rest muscle burns more calories than inactive tissue. These exercises should be done two or three times a week. Flexibility exercises are important because if a muscle isn’t stretched then overtime it will shorten and become less elastic. Therefore joint mobility will decrease and the likelihood of injuries to muscl...
The dynamic stretching exercises I perform include wrist rotations. As almost every exercise in the gym involves the wrist so properly warming up the wrist joint is absolutely necessary especially when the resistance training program include exercises such as bench dips, bench press, overhead shoulder press in which the there is a direct load on the wrist. When leg exercises are to be performed with greater loads like barbell squats, leg press, leg extension, leg curl, lunges etc., it is important to properly warm up the knee joint as well as spine by incorporating some bodyweight walking lunges, knees to ches...
Muscles are very important to the body. Muscles also do a lot for your body. They pump blood through your body, they help you lift heavy objects, and most of all they help your body in almost every way. Muscle is a body tissue that can contract and produce movement (Merriam-Webster Dictionary). Muscles are like the engine of the body; they turn energy into motion. Muscle tone isn’t as important as muscles, but it is very good for the body. Then there is muscular strength, which is a component of physical fitness which is just like muscle tone (DifferenceBetween.net. June 2, 2010 ) Muscle strength is a persons ability to exert force on physical objects using muscles (
The heart, blood and blood vessels make up the cardiovascular system. The function of the cardiovascular system is to evenly distribute blood cells, water and nutrients. The cardiovascular system helps send blood to the body’s tissues. The heart is a muscle and the most important part of the cardiovascular system. Heart attacks, heart failure, and abnormal heart beat is a serious issue for the cardiovascular system these can sometimes lead to death. These diseases affect the heart and its functions (Heart and Cardiovascular disease 2005).
The airway includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles. It carries air between the lungs and the outside elements that surround the body. The lungs are the functional units of the respiratory system and they act as such. They pass oxygen into the body and remove carbon dioxide from the body. Then there are the muscles of respiration. These muscles include the diaphragm and intercostal muscles. They work simultaneously as a pump, pushing air into and out of the lungs during breathing.
From that we then need to define muscular endurance, so muscular endurance is your ability to exert force against a load for a longer period of
Information When you think of a person who is physically fit you probably think of a sprinter, gymnast, weightlifter, football player, or basketball player. There is so much to physical fitness besides being one of those people. For decades, physiologist and fitness organizations have tried to come up with an answer and here it is. “Physical fitness- a measure of the body’s ability to function efficiently and effectively in work and leisure activities, resist hypokinetic disease (diseases from sedentary lifestyles), and to meet emergency situations .” Sometimes they add to the definition stating it is the ability to transmit genes to the next generation. Now, this is the short answer for what physical fitness it is much longer is and detailed
Muscle tissues grow by means of physical activity in the same way they are able to become more well-defined (with regards to physical
The roles of the circulatory and respiratory system both carry important responsibilities and are essential in their jobs to the human body. The circulatory system is one, if not the, most important system in the human body. The circulatory system is made up of the heart, blood, and blood vessels. Within the blood vessels, there are three types: arteries, veins, and capillaries. The heart is an organ made up of cardiac muscle that has a role similar to a pump. When the muscles in the heart contract, it pumps fresh blood away from the heart, through a main artery called the aorta, and to the organs and cells of the body. Nutrients and oxygen then enter the cells through diffusion of the tissues. The respiratory system transports oxygen to the circulatory system. When transporting oxygen to the circulatory system, this will in turn transport oxygen to the rest of the cells in the body. Aside from transporting oxygen to the body, the respiratory system also plays a role in the removal of carbon dioxide and other contaminants in the body. These two systems effectively and efficiently work together in order to supply the body with oxygen and remove carbon dioxide and any other
Can’t stay fit if one doesn’t put forth any effort physical fitness requires physical exercise. But in everyday life one has to do some sort of physical exercise it varies from picking up boxes to walking up and down stairs all day. Physical fitness is a measure of the body’s ability to run at full capacity that measures on a personal level. It measures aerobic endurance, muscular strength, muscular endurance, body composition and also flexibility (Wilson). If one doesn’t exercise ones body doesn’t work at its full potential and exercise affects ones body in many different ways there are also many was to exercise (Wilson). How ones heart and lungs do there job also depends on aerobic endurance. Aerobic and anaerobic exercises can also help with ones muscular endurance (Wilson).
