Rafaela Casandra R. Dantes. (Bachelor of Arts in Communication) Assignment in Physical Fitness 1) Definition of Physical Fitness today. Physical fitness is a general concept defined in many ways by differing scientists. Here two major categories are considered: general fitness (a state of health and well-being)‚ and specific fitness (a task-oriented definition based on the ability to perform specific aspects of sports or occupations). Physical fitness is generally achieved through correct nutrition

triggers responses that return the variable to within the ‘normal range’. Deviation produces a negative response to counteract the deviation. An example of a negative feedback system within the body is the liver when blood glucose levels fall‚ the glycogen from the liver is converted into glucose in order raise the energy levels in cells which is crucial. Vital organs that help to control the homeostatic mechanisms are the brain and nervous system. These vital organs help use to anticipate when key

Negative Feedback Negative feedback is the process by which the outputs tend to reduce the inputs‚ which causes the system to stabilize. It is found in many functions that organisms carry out on a daily basis‚ most notably homeostasis. Negative feedback can be seen during the menstrual cycle‚ during days 5-10 oestrogen levels slowly rise‚ this increase causes the release of the hormones FSH and LH to be inhibited. Also in low concentrations progesterone has a negative feedback effect on FSH

Recall that Jim’s heart and respiratory rate are increased‚ he was sweating and that his mouth was dry before the raise began. Explain what is happening to his autonomic nervous system (including which division is the most active) and specify exactly how those ANS responses are creating the symptoms noted.

Good hydration is important for athletes as their body lose water through sweat to keep it cool down. Control levels of fluid and water balance even before‚ during and after training or during matches are essential aspects for the athletes. For low intensity exercise lasting for a short duration such as low intensity training or during rest between each training session‚ water is very good for rehydration (Nutrition Australia‚ 2009). In addition‚ high intensity and endurance sports last longer than

Mechanical digestion: Is the physical breaking down of larger food into pieces to increase its surface area (the higher the surface area‚ the higher the rate of chemical digestion.
