Katen [24]

Explanation:

Communicable diseases and non communicable diseases have a significant difference. Communicable diseases which are also known as transmissible diseases are an illness which is caused from infection. Most common spread of these diseases are fecal-oral, food, contact with contaminated fomite or skin contact. HIV is an example of communicable diseases. This can be transmitted through intercourse with another. It isn't curable after it reaches a certain point. At an early stage HIV can be functionally cured, but it's hard to detect.

Non communicable diseases are diseases that are not transmitted directly from one person to another. For example, Parkinson's disease, diabetes and osteoporosis. They are responsible for almost 70% of all deaths worldwide. These types of diseases can also be inherited genetically from those with history of non communicable diseases. Its more likely to be inherited rather than showing up. Diabetes is a diseases that causes too much sugar in the blood, making it very unhealthy. You must take insulin in order to balance the sugar intake.

Why is it important to hold a static stretch for at least 10–15 seconds? Include the physiology of the stretch reflex in your re
Sergio039 [100]

Static stretch

Explanation:

Static stretching exercises are done by elongating the target muscles as tolerated and then holding the stretch in that position for a stipulating length of time. This holding time period is usually determined by the individual’s age, activity level, any other previous illness or injuries etc.  

The holding time usually is around 10-15 seconds is especially done to:

  1. Reduce risk of injury, muscle stiffness
  2. Increase mobility, flexibility, range of motion  
  3. Relieve back or joint pains.

The main physiology in stretch reflex:

The stretch reflex is a myotatic reflex which is triggered by the action potentials of la afferent fibers. This causes the excited motor neurons to contract the stretched muscle which in turn reduces the potential.    

The holding in static stretching is to make the elongation of the muscles a habitual length for the muscle spindle fibers and mark it is a new length.

The signals are reduced and the receptors are trained to allow more muscle fiber lengthening. The greatest increase in length or increase in range of motion occurs when the stretch is held for about 10-30 seconds with 2-4 repetitions.
