What is Muscle Hypertrophy?

These adaptations are relevant because the body is being stressed which leads to more blood being needed by the working muscles. With this increase in stroke volume and cardiac output, it also increases the heart rate. Heart rate is the amount of times the heart beats per minute. This means that the heart is working hard and being progressively overloaded increases the efficiency and will improve the performance of the athlete. Another adaptation is oxygen uptake. When the body is being progressively overloaded oxygen uptake is really important because it is the amount of oxygen being delivered to working muscles. This amount increases when exercise begins but decreases as adaptations occur. This is very similar to lung capacity as lung capacity is the amount of air that the lungs can hold. Another physiological adaptation in relation to progressive overload is haemoglobin levels. Haemoglobin is the substance in the blood that binds to oxygen and transports it around the body. These levels are important because it’s telling us how much oxygen and blood is being used and directly relates to stroke volume and oxygen uptake. Muscle hypertrophy is a term that refers to muscle growth together with an increase in the size of muscle cells. For a sprinter this adaptation is very important because it indicates that the muscles have been stimulated and grown and an

When exercising, the weight or stress you’ve produced to the muscles can create resistance and then contraction of the muscles can be drawn out. These contractions enable the muscles significantly increase in size. Along with the increase in size is the increase in strength as well. Repeated exercise, coupled with weight bearing activities, hypertrophy, and medical term for increase in muscle size, of the muscles will be evident.

All athletes regardless of age, gender, genetics or sport can benefit from effective training. It is important that the selected training improves the body’s ability to perform tasks associated with the chosen

Cardiac hypertrophy is the enlargement, or thickening, of the heart muscle. After lots of strenuous exercise the heart muscle will increase. If a person does exercise, a thirty minute jog every day, for six months there will be an obvious increase in many other factors but the heart muscles will have grown in size. These changes are reversible when you discontinue aerobic training.

One of the more prevailing ideologies attached to athletes and coaches alike is the more training one completes the better performance can be obtained. While this method has proven to push athletes to crush records, there comes a point in this action plan when excessive training will cause an athlete to plateau or even deteriorate in performance ability (Wilmore, Costill, & Kenney, 2011). This particular method to training has sparked many a research study in which it is generally found that athletes who train in an excess of double the volume of a typical training program see no additional benefits to performance (Wilmore et al., 2011). There are several consequences to this type of training with the top two being overtraining syndrome and

The study of the human body and its movements has been present for centuries. While there has almost always been an interest in the human body and its way of working, modern technology and scientific discoveries have greatly aided modern medicine and research of human anatomy and physiology. These days, the study of medicine is far more extensive than many people understand, and those who want to pursue a medical field have great amounts of work awaiting. Athletic Training as a profession in this day and age involves extensive schooling, training, and focus when on the job.

In this lab, the focus was to study muscular fitness. In muscular fitness, there are two main components of measurements that are being taken, which are muscular strength and muscular endurance. Muscular strength is an individual’s ability to exert their maximum force. To test muscular strength, there are multiple tests such as 1 RM , Static Handgrip Strength, and Back Strength Dynamometer test. Muscular endurance is an individual’s ability to sustain prolonged muscular contractions. Tests that reveal results about an individual’s muscular endurance would be tests such as YMCA Submaximal Bench Press, Push-Up, and Plank test. It is important to remember that there is no single test for endurance and strength that will tell an

For example many people will show an improvement in strength from the first session to the second session. This improvement is due to CNS adaptation because there is no hypertrophic gain during this short period. Another example which proves the importance of CNS adaptations related to strength gains is that strength performance may increase by 30% while hypertrophic gains may only be 15%, thus half of the strength gains is attributable to CNS adaptations. Generally in the first few months of strength training CNS adaptations account for a larger percentage of the strength gain than hypertrophic adaptations. To illustrate the importance of CNS adaptations in the early part of training, it should be noted that electrical stimulation can increase the rate of strength gains. Hypertrophy is an important factor in improved strength performance. Strength training brings about an increase in the size and number of myofibrils. It is speculated that during and following a high intensity strength training session the neuroendocrine responses will bring about an increased amino acid uptake and will increase the rate of protein synthesis. Optimal hypertrophic gains require adequate recovery between workouts to permit the rate of protein synthesis to exceed the rate of protein degradation. It should also be noted that strength training also stimulates bone and

Football is the famous sport played in the world, and players need technical, tactical and physical skills to succeed. Strength is components of physical fitness which very important to increase football performance as important as with others components of physical fitness, such as speed, coordination and flexibility (Ruivo, Carita, & Pezarat-Correia). According to Taha, Lee, Ahamed, Joseph, and Omar (2016) strength training is the type of exercises that make the muscles to stretch hundred percent which can helps to build the strength, anaerobic, and increase in size of skeletal muscles using resistance training . Strength training also can increases sport performance and also to maintaining condition of athletes. Another study by Fábrica, López, and Souto (2015) state that strength or power training could be of great interest to the sport community especially in sport like football, in which performance is include the high intensity intermittent activity like explosive strength or power is one

The HHD is a well-known device that is published in many articles. It is been used in different type of population (healthy and sick people, children and older subjects). The HHD is easy to use even by a novice therapist. Looking at the way the test is done and how it read the muscle strength, this device does no take a long time to administrate it to a subject. By far this is the best device I know to measure the ankle

twitch muscles. Fast twitch muscles have a fast form of myosin ATP and are very

Hypertrophy training is a very specific type of training. It is not a goal that all athletes may want to strive for. Hypertrophy training is training to increase overall muscle mass and muscle size in the individual. Some athletes may wish to increase their physical size, but not necessarily to the size of Arnold Schwarzenegger.

The overload principle is the basis for all exercise training programs. For a muscle to increase in strength, the workload to which it is subjected during exercise must be increased beyond what it normally experiences. In other words, the muscle must be overloaded. Muscles adapt to increased workloads by becoming larger and stronger and by developing greater endurance.
