The legs play a crucial role in swimming. They are not only responsible for providing propulsion to move you forward in the water but also for maintaining balance and stability. Whether you’re a beginner just learning to swim or an experienced swimmer looking to improve your performance, understanding how to use your legs effectively is essential.
Leg Movements in Different Strokes
Freestyle
In freestyle swimming, the leg movement is known as flutter kick. To perform a proper flutter kick, lie on your stomach in the water with your body in a straight line. Your legs should be extended, and your feet should be slightly turned outwards. Start by kicking your legs up and down in a quick, rhythmic motion. The movement should come from your hips, with your knees slightly bent but not overly so. Keep your ankles relaxed and flexible, allowing your feet to move freely through the water. Each kick should be a smooth, continuous motion, with the top of your foot just breaking the water’s surface on the up – kick and your toes reaching downwards on the down – kick.
Breaststroke
The leg movement in breaststroke is distinct. Begin by starting in a floating position on your front. Bend your knees and bring your feet towards your buttocks, keeping your heels close to your thighs. Then, push your feet outwards and backwards in a circular motion, like you’re pushing the water away from your body. Your feet should be turned outwards, with the soles of your feet facing the sides. As you push your feet back, straighten your legs until they are fully extended. After the push, quickly bring your feet back together in a gliding motion. This leg movement, combined with the arm stroke, propels you forward in the water.
Backstroke
For backstroke, the leg movement is similar to the flutter kick in freestyle but with a few differences. Lie on your back in the water, keeping your body straight. Your legs should be extended, and your feet should be slightly turned outwards. Start kicking your legs up and down. The up – kick should be more forceful, with your toes pointed upwards. As your leg moves down, keep your knee slightly bent. The down – kick should be a more relaxed motion. The key is to maintain a steady rhythm with your kicks to keep yourself moving backwards through the water.
Butterfly
The butterfly stroke requires a powerful leg movement called the dolphin kick. Start by floating on your front in the water. Your legs should be together. Bend your knees slightly and lift your feet up towards the surface of the water. Then, quickly push your legs downwards in a whip – like motion. Your legs should move together as one unit, and the movement should come from your hips. As you push your legs down, your feet should move downwards and outwards, creating a strong propulsion force. The dolphin kick is a more advanced leg movement and requires good core strength and flexibility.
Exercises to Improve Leg Strength for Swimming
Pool – Based Exercises
Kick – Board Exercises: Use a kick – board to isolate your leg movements. Hold the kick – board with both hands and keep your upper body relaxed. Then, perform the leg movements of your chosen stroke, such as flutter kick for freestyle or breaststroke leg kicks. Start with short distances, like 25 meters, and gradually increase the distance as your leg strength improves. You can also vary the intensity of your kicks, from slow and controlled to fast and powerful.
Underwater Kicking: Submerge yourself underwater and perform leg kicks. This adds extra resistance to your leg movements, helping to build strength. You can do this for a set number of kicks or for a specific time, such as 30 seconds. Make sure to come up for air regularly.
Wall – Assisted Kicking: Hold onto the side of the pool with one hand and extend your body horizontally in the water. Then, perform leg kicks, focusing on the proper technique. The wall provides support, allowing you to focus on the movement of your legs without having to worry about balance.
Land – Based Exercises
Squats: Stand with your feet shoulder – width apart. Slowly lower your body as if you’re sitting back into a chair, keeping your back straight and your knees behind your toes. Then, push back up to the starting position. Squats work your quadriceps, hamstrings, and glutes, which are important muscles for swimming. Do 3 sets of 10 – 15 squats.
Lunges: Step forward with one leg, lowering your body until both knees are bent at a 90 – degree angle. Make sure your front knee doesn’t go past your toes. Then, push back up to the starting position and repeat with the other leg. Lunges target your leg muscles, including your quadriceps, hamstrings, and calves. Do 3 sets of 10 lunges on each leg.
Calf Raises: Stand on the edge of a step with your heels hanging off. Rise up onto the balls of your feet, lifting your heels as high as you can. Then, slowly lower your heels back down. Calf raises strengthen your calf muscles, which are used in swimming for kicking. Do 3 sets of 15 – 20 calf raises.
Tips for Efficient Leg Use in Swimming
Maintain a Steady Rhythm
In all strokes, maintaining a steady rhythm with your leg movements is crucial. A consistent rhythm helps you generate a more efficient propulsion force. Try to count your kicks in your head or listen to the sound of your kicks in the water to keep a steady pace. For example, in freestyle, aim for a set number of kicks per stroke cycle, like 6 kicks for every 2 arm strokes.
Engage Your Core
Your core muscles, including your abdominal and back muscles, play a role in leg – powered swimming. When you engage your core, it provides a stable base for your leg movements. This allows you to transfer the power from your legs more effectively. To engage your core, pull your belly button in towards your spine and keep your back straight while swimming.
Relax Your Legs
While it’s important to be strong and powerful with your leg kicks, it’s also essential to keep your legs relaxed. Tensing up your leg muscles can lead to fatigue and inefficient movement. Make sure your ankles are flexible, and your knees are not overly rigid. A relaxed leg can move more freely through the water, making your kicks more efficient.
Common Mistakes and How to Avoid Them
Kicking Too Hard or Too Fast
Some swimmers make the mistake of kicking too hard or too fast, thinking it will make them swim faster. However, this can actually waste energy and disrupt your stroke rhythm. Instead of focusing on force, focus on the proper technique and a smooth, efficient kick. Use your leg strength in a controlled way to generate consistent propulsion.
Not Using the Right Part of the Leg
In different strokes, specific parts of the leg are used more effectively. For example, in freestyle, the movement should start from the hips. If you’re only using your lower legs to kick, you’re not getting the full power of your leg muscles. Pay attention to the proper form and make sure you’re using the correct part of your leg for each stroke.
Ignoring the Importance of Balance
Your legs not only propel you forward but also help maintain balance in the water. If you’re focusing too much on kicking for speed and neglecting balance, you may find yourself tilting or losing your streamline. Keep your body in a straight line and use your leg movements to help keep you stable in the water.
Dealing with Leg Fatigue and Cramps
Prevention
To prevent leg fatigue and cramps while swimming, make sure to warm up your legs before getting in the water. You can do some light jogging or leg – stretching exercises on land. Also, stay hydrated by drinking plenty of water before and after swimming. If you’re swimming for an extended period, take regular breaks to rest your legs.
What to Do if You Get a Cramp
If you experience a leg cramp while swimming, don’t panic. Try to stay calm and float on your back. Gently stretch the cramped muscle. For example, if your calf is cramped, pull your toes towards your shin. If you’re in a pool, you can hold onto the side of the pool and stretch the muscle. Once the cramp subsides, swim slowly and carefully to the edge of the pool.
Conclusion
Learning how to swim with your legs effectively is a key part of becoming a proficient swimmer. By understanding the leg movements in different strokes, practicing the right exercises to build leg strength, following the tips for efficient leg use, and knowing how to deal with common issues like fatigue and cramps, you can improve your swimming performance and enjoy the water more. Remember, consistent practice and attention to technique are the keys to mastering leg – powered swimming. So, get in the pool, start practicing those leg kicks, and watch your swimming skills improve.
