The Stroke 划水
The breaststroke has several benefits for fitness swimmers: It’s an excellent way to vary the challenge and pace of a workout, the leg motion is terrific for toning your inner and outer thighs, and the arm motion is great for toning your chest muscles.
Contrary to how it might look, breaststrokers do not move their arms and legs simultaneously when they swim. Rather, they pull, inhale, kick and glide, although there is some overlap between the elements. There should be a clear distinction between the kick and pull. As with other swim strokes, it’s a good idea to break down the breaststroke into its component parts before trying to put it all together.
Arm Motion 手部的動作
Imagine your hands tracing a heart-shaped Valentine in the water, beginning and ending with your arms extended in front of you, just below the water’s surface. During the pull, your arms should trace a smooth, outward, downward curve followed by an accelerated, sharper upward movement that brings your hands together beneath your chest. In the recovery, your arms should shoot straight forward, returning to your starting position.
Leg Motion 腿部的動作
Most fitness and competitive swimmers prefer the newer, narrower “whip kick” to the old-fashioned “frog kick.” Bend your knees-not more than hip-width apart – and bring your heels together near your buttocks. Simultaneously flex your feet and turn your toes outward so your lower legs form a V. then whip your lower legs down, around and together in an outward, backward semi-circle, finishing with your knees straight and your toes pointed. This circular back-ward motion is the main propulsive force behind the kick.
Body Position 身體的體位
Prone and streamlined. At the beginning and end of your stroke, extend your arms in front of you with your hands together, four to eight inches below the water’s surface. Your palms and thumbs should be angled slightly downward. Straighten your legs behind you, keeping your hips and feet just below the water’s surface. Your hips should be undulating visibly during the stroke cycle.
Breaststroke Breathing 蛙式呼吸
Head Position 頭部的位置
Hold your head still, with your eyes fixed at a point on the water just in front of your hands. Keep your chin locked and slightly tucked.
Timing 時間點
Two common breaststroke errors are breathing too early in your stroke, which robs your pull of its power, and lifting your chin to breathe. Instead, keep your face in the water as your hands press down and outside the shoulders, then breathe as your hands reverse direction and sweep inward again.
TIP Breathe by lifting your torso rather than just your chin. As your hands sweep inward, your arm action should lift your shoulders out of the water. Inhale as your body clears the water. Fully extend your hands before your face goes back under.
Breaststroke Coordination蛙式的協調
The correct sequence should be: Pull, inhale, kick and glide. Bend your knees to begin your kick at a pint just after you’ve inhaled, with your arms under your chest. Then, as your arms begin their recovery, your knees should be bent to their fullest – some breaststrokers have enough flexibility to touch their heels to their buttocks. Your legs should supply at least 50 percent of your propulsion in the breaststroke.
