Swimming Assignment

Water Safety is best described as the recognition of potential aquatic hazards, the development of survival skills, and the safe rescue of others. This means that individuals who are water safe are able to identify potential dangers in the water, such as strong currents or deep areas, and take appropriate precautions. They also possess the necessary skills to survive in water, such as knowing how to float or tread water. Additionally, they are capable of rescuing others who may be in distress, ensuring the safety of themselves and those around them.

The correct answer is C. a dolphin kick. In butterfly swimming, the kick is referred to as a dolphin kick. This kick involves the swimmer's legs moving in a simultaneous up and down motion, similar to the movement of a dolphin's tail. It is a powerful and efficient kick that helps propel the swimmer through the water.

Approximately 80% of the people who drown are male, while 20% are female.

In a situation where a rescuer must enter the water after attempting a dry rescue of a conscious person in difficulty, taking an aid, preferably buoyant, to keep between the rescuer and the person in difficulty is the best option. This is because the aid will provide a barrier between the rescuer and the person, ensuring their safety and preventing any potential harm or interference from the person in difficulty. It also allows the rescuer to maintain a safe distance and have better control over the situation.

This statement is incorrect because students who cannot float can still learn to swim. Floating is just one aspect of swimming and there are other techniques and skills that can be taught to help them swim.

The correct answer is E because it suggests that the decision to introduce beginners to deep water should be based on the teacher's assessment of the beginner's physical and psychological readiness. This implies that the teacher should take into account factors such as the beginner's swimming skills, ability to float, and overall confidence in the water before introducing them to deep water. This approach ensures that beginners are introduced to deep water at a suitable time, when they are most likely to feel comfortable and safe.

Bilateral breathing refers to the technique of breathing on alternate sides while swimming. This means that the swimmer will inhale on one side during one stroke, and then switch to inhaling on the other side during the next stroke. This technique helps to balance the body in the water, improve stroke symmetry, and increase overall efficiency in swimming.

The characteristics mentioned, such as grasping the rescuer, not using arms and legs for support, being unable to turn around, being in a vertical position, and being unlikely to respond to instructions, suggest that the person is conscious but unable to swim. This indicates that they are a conscious non-swimmer.

In backstroke kick, the knees should remain below the water. This is because keeping the knees below the water allows for a more efficient and streamlined kick. When the knees are below the water, it helps to create a stronger downward propulsion, generating more power and speed in the kick. Additionally, keeping the knees below the water helps to maintain a horizontal body position, reducing drag and improving overall performance in backstroke swimming.

During the Freestyle kick, the feet should be plantar flexed but loose. Plantar flexion means pointing the toes away from the body. This position allows for a larger surface area of the foot to push against the water, creating more propulsion. However, the feet should also remain loose and relaxed to maintain flexibility and prevent tension or cramping in the muscles. This combination of plantar flexion and loose feet helps to optimize the effectiveness and efficiency of the kick in freestyle swimming.

The correct sequence in Breaststroke is to first pull, then breathe, followed by a kick, and finally a glide. This sequence allows for efficient propulsion and breath control. Pulling helps to generate forward momentum, breathing is timed to coincide with the recovery phase of the arms, the kick provides additional propulsion, and the glide allows for a moment of rest and streamlined body position.

The correct answer is B. eddy turbulence around the body and limbs. When a student is performing freestyle, the forward motion can be slowed down by the presence of eddy turbulence around the body and limbs. Eddy turbulence refers to the swirling or turbulent motion of water caused by the movement of the swimmer's body and limbs. This turbulence creates resistance in the water, which can impede the swimmer's progress and slow them down. Therefore, the presence of eddy turbulence is a factor that can slow down the forward motion of a student performing freestyle.

The objective of single arm practice in Freestyle and Backstroke is to make the link between recovery, entry, and catch. This means that the swimmer focuses on the coordination and timing of these three movements in order to swim efficiently and effectively. By practicing each arm individually, the swimmer can better understand how these movements work together and improve their overall technique in these strokes. Strengthening the arm, ensuring the wrist enters first, and making the link between kick, pull, and catch are not the main objectives of single arm practice in these strokes.

After a dive entry, it is important for a student to gently lift their head and aim the locked hands towards the surface. This is because lifting the head allows the student to maintain a streamlined position and reduce drag in the water. Aiming the locked hands towards the surface helps to maintain balance and control the direction of the dive. This technique is crucial for a successful dive entry and sets the foundation for a smooth transition into the water.

At the commencement of the propulsive phase of the Breaststroke kick, the feet are in the hooked and 'V' position. This means that the feet are flexed and turned outwards, with the toes pointing away from each other and forming a V shape. This position allows for a larger surface area to push against the water, increasing propulsion and forward movement. The hooked position also helps to maximize the power generated from the legs during the kick.

The correct answer is D. This is because sculling refers to a technique used in swimming where the hands move in a smooth and continuous inward and outward motion. The hands are angled at approximately 45 degrees during this action. This movement helps to generate propulsion in the water and maintain stability while swimming. It is different from the other options which describe different hand actions or angles.

During the push phase of Freestyle, the hand moves outwards and upwards. This movement helps to generate propulsion in the water by pushing against it. By moving the hand outwards, it creates a larger surface area to push against the water, while moving it upwards helps to lift the body out of the water and maintain a streamlined position. This combination of movements allows swimmers to effectively propel themselves forward during the push phase of the Freestyle stroke.

The correct answer is B. salah, E. the density of the water displaced. The buoyant force is the upward force exerted on an object submerged in a fluid. It is equal to the weight of the fluid displaced by the object. In this case, the buoyant force is provided by the density of the water displaced, as well as the incorrect answer salah, which means wrong in Indonesian language. The amount of muscle and bone in the student's body and the amount of air in the student's body do not directly provide the buoyant force.

When the water is unclear and the depth at the entry point is unknown, a slide in entry is the most appropriate choice. This is because a slide in entry allows the person to enter the water slowly and cautiously, reducing the risk of injury if the water is shallow or there are obstacles beneath the surface. It also allows the person to assess the clarity of the water as they enter, ensuring their safety. A dive entry or a compact jump would not be suitable in this situation as they require a clear understanding of the depth of the water. A step in entry or a stride entry may also be risky if the depth is unknown.

The statement describes a situation where the rescuer kicks away from the person in trouble and assumes a defensive position. This action is commonly known as a reverse, where the rescuer moves away from the person in need to create distance and ensure their own safety.

The Sidestroke arm and leg action are examples of an independent action because they are performed separately and do not rely on each other for movement. In the Sidestroke, the arms and legs move independently in a coordinated manner, with one arm pulling while the opposite leg kicks. This allows for a smooth and efficient stroke, as each limb can generate power and propulsion without being hindered or dependent on the other.
