The gluteus maximus the largest of the butt muscles is the main driver for hip extension and power propulsion. Core abdominal and lower back muscles that keep the body steady in streamlined positions in the water to reduce drag. These joints allow remarkable ranges of motion in several planes of movement. Besides increased muscle toning, swimming has a variety of added benefits that youve probably never taken into consideration. The swimming dive start is defined as the time from the starting signal (the gun or beep) to when the centre of the swimmers head reaches 15m down the pool. Use your core muscles, which are much larger than other muscles, to help you do so quickly. The applied force can be broken down into vertical, horizontal (antero-posterior), and lateral (side-to-side) components and produce the swimmer's takeoff velocity. In contrast, the horizontal force for the track start develops earlier and is followed by two separate peaks. An hour or so at the pool after a hectic day at work will leave you feeling refreshed and energised. A summary of muscles used in swimming for the four strokes can be found below.

Several studies suggest that the new block configuration can have an effect on start performance. Aggressive arm action and a strong rear-leg drive are used to generate force and forward momentum in the early part of the dive, but the front leg typically generates the major propulsive force on a traditional starting block (figure 6.7).

The scapula is moved anteriorly and laterally along the back, moving the arm and shoulder joint anteriorly. RTD RTD stands for rate of torque development and isusually measured in Newton-meters per second. Elevate Scapula The shoulder blades are raised in a shrugging motion. If both shoulder blades are protracted, the scapulae are separated and the pectoralis major muscles (in the front of the chest) are squeezed together. The fastest starts are the ones that can maintain the highest velocity for the longest after they enter the water. In general, force, including GRF,is measured in Newtons. So, swimming clearly has several health benefits. These are major powerhouse muscles used in all swimming strokes. Despite different stroke techniques, the butterfly uses the same muscle as freestyle and backstroke to keep you moving forward.

Swimming is a great way to increase your muscular strength and endurance. Down Rotation Scapula The opposite of upward rotation, downward rotation occurs as the arm returns from being overhead. Any lateral force is essentially wasted and should be minimized. The main propulsive force of the backstroke is the latissimus dorsi which applies force when pulling. Moments areusually measured in Newton-meters. Compliance The opposite of stiffness is compliance. Recent research suggests that kicking alone is responsible for 10-15% of the swimming speed. Isokinetic Isokinetic exercise is performed on adynamometer which provides variable resistance tomovement so that regardless of the effort exerted, the movement takes place at a constant speed.
