Describe each of the FITT training principles. (Site 1)

F is for frequency(Ex: How many times a week you do a workout), I is for intensity(Your target heart rate during the activity), T is for time(how long you did the activity), T is for type(The type of activity you did)

Explanation:

F) Frequency is how often you exercise. Usually we measure this by number of days each week.

I) Intensity is how hard your exercise. We might categorize this as low, moderate, or high intensity.

T) Time refers to the time of day you exercise and how long each session lasts.

T) Type refers to what kind of exercise you are doing. For example, you might do cardiovascular activity (also known simply as 'cardio'), strength training, or a combination of the two.

Explanation:

during longer space exploration trips, crewmembers may develop vision impairment risks and short-term cardiac atrophy or a decrease in the size, strength, weight, and activity of the heart during space flight because they can experience microgravity. in addition, the long-term medical condition is loss of bone mineral density and radiation exposure.
