rotary kick (egg beater)

Answer 13

kicking technique used for treating water

Question 14

F.I.T. Principle

Answer 14

fitness principle that states that workouts must be sufficient of frequency (F), intensity (I) and duration of time (T) to be effective

Answer 15

fast and efficient turn

done in tuck position

Question 16

competetive event
any stroke allowed
often used for front crawl

Question 17

Answer 17

resistance caused by an object´s surface texture as it moves through a fluid

Question 18

glide

Answer 18

stage of stroke after power phase

body keeps miving without any effort

Question 19

hydrodynamics

Answer 19

science that study the motion of fluids and forces on solid bodies in fluids

Question 20

intensity

Answer 20

how hard you work out when you exercise

Question 21

law of acceleration

Answer 21

principle by which a body´s speed depends on how much force is applied to it and the direction of that force

Question 22

law of action and reaction

Answer 22

principle that for every action there is an equal oppoite reaction

Question 23

law of inertia

Answer 23

principle that a force must be applied to move a body from rest, to stop a moving body, or to change direction of a moving body

Question 24

law of levers

Answer 24

principle that movement of levers is related to the force applied, the resistance that occurs, the force arm and the resitance arm

Question 25

overload

Answer 25

fitness principle based on working somewhat harder than normal so that muscles and cardiovascular system must adapt
