SWIMMING STROKES

Christopher Keller, 2019

he is from enjoyswimming.com and he describes freestyle stroke as the fastest and most efficient of the swimming strokes used in competition

breast stroke

is swum with the body facing down. The arms perform semi-circular movements, and the legs perform a frog kick

release

no force should be applied at the end of the upsweep, as the forearm and hand move primarily upward. Otherwise, water would be pushed up, which increases drag and pushes the hips down. The shoulder, upper arm, and elbow exit the water in this order, followed by the forearm and hand with the palm turned inward to minimize drag

butterfly

of all the different swimming strokes, this is probably the most challenging. It requires a great deal of strength and coordination that takes time to develop

entry and extension forward

once the hand has passed the head, it enters the water with the fingertips. The rest of the arm moves through the hole opened by the hand in the water and continues to move forward underwater until it is fully extended

recovery

the arm is brought forward over water, with the elbow leading and the forearm relaxed and dangling. The recovery should be compact, meaning that the hand hovers above the water and slides close past the rib cage

90%

the arm stroke accounts for as much as _________ of the propulsion in the front crawl

90 degrees

the elbow is bent about ___________ and maintains this angle during the subsequent propulsive phases of the arm stroke in the catch

10%

the flutter kick only accounts for _________ of the propulsion in the front crawl

allamericanswim.com

their contributors state that freestyle, favored by long-distance swimmers, is considered the most efficient stroke

swimming

typically consists of repeating a specific body motion or swimming stroke to propel that body forward

3-6 feet

after the arm pulling phase, when the body is inclined at 45 degrees, the face is directed downwards and slightly forward, the eyes are fixed at a point about _________________ ahead

freestyle stroke

also known as front crawl, is the fastest and most efficient of the swimming strokes used in competition

back crawl

another term for back stroke

front crawl

another term for freestyle stroke

whip kick

another term for frog kick

catch

at the end of the downsweep, the shoulder, elbow, and hand are positioned on the same vertical plane. The shoulder is at the top while the hand is at the bottom

20-28 inches, 50-70 cm

depth of the hand at the bottom during a catch

sidestroke

just like the name suggest, you will swim this stroke on your side. Begin by positioning your body on one side in the water. You may be less familiar with this stroke because it is not used during competitive events

side stroke

sidestroke is a swim stroke swum on the sides. It is not used in competitions and therefore less known nowadays

butterfly stroke

the second-fastest swimming stroke and is quite exhausting

breaststroke

the slowest swimming stroke. Because it is so slow, it can be done for longer periods of time, serving as an endurance workout

breaststroke

this involves separate movements for your arms and legs. Your body is in the same horizontal position, but you will use different motions to propel yourself through the water. The breaststroke is swum with the body facing down. The arms perform semi-circular movements, and the legs perform a frog kick

insweep

this is the first propulsive phase of the arm stroke. Once the arm is positioned at the catch, the upper arm is moved in toward the rib cage while the elbow maintains its angle, and no rotation takes place in the forearm

upsweep

this is the second and most propulsive phase of the arm stroke, during which the direction of the arm movement changes. At the beginning of the upsweep, the forearm rotates so that the underside of the forearm and the palm now face backward, upward, and outward. The hand then moves from below the chest backward, upward, and outward toward the hip. The elbow remains slightly flexed so that the palm and forearm remain facing backward as long as possible

freestyle

this takes you farther than other strokes without expending more energy. If you like to set your swimming workouts to a lap count, this will help you reach your goal faster

downsweep

to begin, we should imagine that one of the arms is extended forward underwater at the end of its recovery. The other arm has started its propulsive phase. The body is rotated downward on the side of the extended forward arm

backstroke

unlike with most other swimming strokes, your face will not be in the water. Instead, you will be on your back in the water, just as the name suggests. In terms of speed, it is slower than the front crawl and butterfly but faster than the breaststroke

back stroke

uses alternating and opposite arm movements. The legs perform a flutter kick, similar to the one used in the front crawl

unilateral breathing

you breathe in every other arm stroke. As a consequence, you always breathe in on the same side. This gives you plenty of oxygen and is especially useful in short distance races. Your swim stroke can become lopsided however if you use this breathing pattern all the time, for example, while training

bilateral breathing

you breathe in every third arm stroke. As a consequence, you alternate your breathing sides. This pattern is symmetrical and improves your balance as it forces you to become used to breathing on both sides. Long distance and fitness swimmers commonly use this pattern
