equate large muscles with strength‚ that is not necessarily so. Strength is not directly proportional to the size of a muscle. First‚ you need to decide which muscles you want to strengthen‚ then find the best way to exercise those muscles so they will respond with increased strength. Then keep increasing the weight load to challenge the muscles. For instance‚ add 1 pound now and another pound in a month‚ and so on. The more you load the muscles‚ the stronger they will become. Muscles respond quickly

stomach has three layers of non-striated muscle in its wall and an inner lining of columnar epithelium with goblet cells. The tissue connecting the lining with the muscular coat is areolar tissue. Non striated muscle is a type of muscle tissue‚ which is also called involuntary‚ smooth or plain muscle. It still contains the protein filaments; they do not lie in an ordered pattern and therefore do not produce the banding characteristics of striated muscle. The muscle fibres are spindle or cigar shaped

keep the muscles activated. To grant this the heart pumps higher frequency of blood increasing the heart rate. Heart pumps blood through arteries faster resulting in a high blood pressure. Exercise increases the stroke volume (the amount of blood pumped in one beat)‚ so an increase in stroke volume means that the heart can pump enough blood to the body with fewer beats per minute. Even after the exercise the heart rate will remain high for some time. The dilation of the active muscles increases

Humans breathe and speak daily without a thought of what really goes into this one aspect of communication. Even though breathing and speaking may seem like a mindless process‚ there are a number of muscles‚ ligaments and body parts that go into the mechanisms that make life what it is. In order to live and speak‚ we must be able to breathe. Respiration is the act of breathing. The act of drawing in a breath‚ or inspiration is the process of in-taking air. Air is taken in through the upper airways

Exercise works by working the muscles in the affected area‚ this leads to an increased demand on blood in the worked area which results in an increase in blood flow to the area. The increased blood flow leads to the opening of the arteries over time. Applying heat is used

artificial versions help the body build muscle and supply more energy for longer periods of time (Britannica). Athletes’ goals are to better‚ stronger‚ and faster than they were the day before. The pressure to excel and be the best pushes them into using stimulants and performance-enhancing drugs to add an edge to their abilities. Anabolic steroids‚ shots of modified testosterone‚ increase body mass and build muscle tissue. Creatine‚ a popular supplement‚ builds muscle‚ strength‚ and heightens player’s

Introduction: Every muscle has lactic acid.According to many people Lactic acid is nasty stuff produced in our muscles during exercise‚ cause soreness‚ muscle fatigue‚ does not contribute to exercise performance‚ muscle does not use it for fuel‚ and better athletes makes less of it. But they all are wrong or in other words they are a lay. Instead Lactate acid is made of Lactate ion called (Lactate) and Hydrogen Ion. C3H6O3----->C3H5O3++H- C2H3OHCOOH--------->C2H3OHCOO+ +H- Hydrogen ion is the acid

Alzheimer’s disease is significantly decreased. Studies indicate that exercising raises the count of T-lymphocytes (T-cells) in the immune system‚ making the body more resistant to viruses. Weight training and cardiovascular exercise increase strength of muscles and the heart and eliminates excessive weight gain and heart disease. Some studies suggest people who participate in regular physical activity live two to three years longer. Benefits of Physical Activity Whether it is for sports‚ good health
