Label the following activities as either aerobic fitness, anaerobic fitness, muscular strength, muscular endurance, or flexibili
vlada-n [284]

Answer:

           

Explanation:

Soccer -- aerobic

Wall sits -- anaerobic

Max lift bench press -- strength

Jogging -- aerobic

Sprinting -- anaerobic

Stretching -- flexibility

Planks -- both strength and endurance

Basketball -- aerobic

Squats -- anaerobic

Speed walking -- aerobic

Sit-ups -- anaerobic

Yoga -- flexibility

Swimming -- aerobic

Aerobic fitness -- it is an ability for our bodies to transport and use the oxygen, in order to produce the energy we need for our muscles. During aerobic fitness, our heart rate and breathing increase for some period of time.

Anaerobic fitness -- oxygen is not used. Compared to the aerobic fitness, it is more quick, more energy is used, and the maximum effort is performed, and it lasts shorter than aerobic fitness.

Flexibility  -- it includes stretching, yoga, Tai-Chi. It is good because it lengthens our muscles. It increases physical and mental relaxation, it prevents our bodies from injuries, reduces soreness.

Muscular strength -- it's occurring in a short period of time and the maximum of our strength is used. By definition, it is the amount of force a single muscle can produce with a single MAXIMAL effort.

Muscular endurance --  the word says it itself -- how much we can endure.

Compared to the strength, which is manifested in a short amount of time, but used to its maximum, in this type of exercise we are more focused on the enduring. It is muscle's ability to endure repeated action against a resistance for a certain amount of time.

The most dangerous route of drug administration is ________________ injection.
ludmilkaskok [199]

Answer:

Intravenous injection (IV)

Explanation:

 Injectable medication administration should be performed efficiently, safely and responsibly, in order to achieve the goals of the implemented therapy. Most drugs can be administered by a variety of routes. The choice of the appropriate route in a given situation depends on both the drug and patient-related factors.

   Intravenous (IV): should be administered slowly for several hours into one of the superficial veins and with monitoring of the patient's reactions. The drug reaches the bloodstream directly and the effects are produced immediately. Once a drug is injected, there is no way to withdraw it. It is the most dangerous route and vital organs such as the heart, brain, etc., are exposed to high concentrations of the drug.
