My aim of this Programme

My main aim in this programme is try to improve the strength of my arms. I notice that my arms are letting me down in a lot of ways, so I decide to strength up my arms. This is also because not just only will improve me in swimming, it will improve every sport I do.

 

Purpose of warm up

It is imperative to perform a warm up or serious injuries could be incurred. Warm up help you to be prepared for exercise, by increasing of speed the oxygen release to the muscle, and raising the heart rate and the body temperature. Stretches are also one type of warm up.

The muscle works better while it is warm up in several reasons.

  • The release of adrenaline will increase heart rate and dilate capillaries, which in turn enable greater amounts and increased the pace of oxygen delivery to the muscle.
  • Increase muscle temperatures associated with exercise will facilitate enzyme activity; this increases muscle metabolism and therefore ensures a readily available supply of energy.
  • Increase production of synovial fluid ensures efficient movement at the joints.
  • Warm ups could also increase in the speed of nerve impulse conduction.
  • Increased temperature can also enables greater extensibility and elasticity of muscle fibres.
  • It lowers blood pressure

A warm-up designed to prepare you to swim your best, whether in a meet or practice, will have you more ready if it goes beyond simple physiology.

      In 1977, Swedish researchers Astrand and Rodahl found that muscle cell metabolism and the rate of oxygen exchange from the bloodstream to muscle tissue increase 13 percent for every degree of muscle temperature increase. As it warms, muscle tissue also becomes suppler, reducing the risk of strains and tears. Yet typical water temperature is usually 15 to 20 degrees lower than our body temperature, meaning your first plunge can actually have a chilling effect on your muscles, constricting blood vessels and reducing circulation for the first few minutes. This can cause binding of muscle tissue and an increase in lactic acid levels. A few minutes of light calisthenics before entering the water will increase your body's resistance to that initial shock. Simply increasing the energy level of the range-of-motion exercises suggested above can do that nicely.

Get into the flow and feel of the water. Your first five to ten minutes of swimming should be lazy, fluid, and exploratory. Concentrate exclusively on how you're feeling as you gradually increase intensity. Change strokes frequently to get more joints and muscle groups lubricated. My practices always start with a repeated cycle of one lap free, one back and one breast (I excuse myself from fly until after warm-up), for 5 or 10 minutes. Next, I alternate drill and swim laps for a while to begin to tune up the neuromuscular system. Martial artist Bruce Lee wrote that fine skills should be practiced only when your muscles are fresh. Skilful swimming requires very precise movement patterns, so it helps to do stroke drills and technique work before doing any hard work to reinforce the desired precise movement patterns of skilful swimming. Warm-up may be the most valuable time to do balance drills, because the drills establish a pattern of relaxed and fluid movement.

Another highly effective warm-up drill is "minus-cycle" swimming. Count your strokes each length and limit yourself to one less stroke cycle (2 individual arm strokes) per length than your normal stroke count. You'll intuitively discover ways to get more out of each stroke. Your technique will improve steadily from devoting attention to it in every workout, and a technique-intensive warm-up will provide the perfect "set-up" for the harder swimming to follow.

It improves performance, helps players get mentally prepared and is a great step towards injury prevention.

A warm up and cool down are the two cardinal principles of any sport. The same is true of swimming. If you think that swimming is a slow and low impact exercise and doesn't require warm up, then you are dead wrong. When you start swimming, without a warm up, your blood circulation, heart rate and your body as a whole are in a state of rest. If you start swimming suddenly your body has to change from a passive to an active state in a very short time. This can cause injuries and loss in efficiency. For a safe and healthy swim you need a good warm up and cool down. Even muscle stiffness would reduce considerably because of this.

To get 100% from your swimming your body has to invest a few minutes in warming up. A warm up makes your body ready for swimming and you actually swim faster and better because of it. It enables your body for a full range of motion in all the strokes. Your muscle fibbers get elongated and connective tissues that attach the muscles to the bones get ready for more vigorous activity. Although there is no hard and fast rule for warm up but generally the equation says that, more the muscle mass or age more the time you need for warm up and obviously, cool down. You not only swim better with warm up but you also reduce the chances of injuries and illness considerably.

Purpose of cool down

After exercise, you should do a similar process to be followed in order to prevent unnecessary discomfort or injuries. This is to slowing the heart rate so that the heart remains elevated. The purpose is to keep metabolic activity high, and capillaries dilated, so that oxygen can be flushed through the muscle tissue, removing and oxidising any lactic acid that remains.

The purpose of the cool-down is the reverse of the warm-up. At this point, your heart is jumping and blood is pumping furiously through your muscles. You want your body to redirect the blood flow back to normal before you do anything else. You also want your body temperature to decrease before you hop into a hot or cold shower; otherwise, you risk fainting. Cooling down prevents your blood from pooling in one place, such as your legs. When you stop exercising suddenly, your blood can quickly collect, which can lead to dizziness, nausea, and fainting. If you're really out of shape or at high risk for heart disease, skipping a cool-down can place undue stress on your heart.

After exercise or strenuous physical activity, it is important to decrease your body temperature gradually till your normal body temperature is reached. It is just as important to include your stretching program during the cool down process to reduce soreness in your muscles the following day.

Cool-down is your recovery phase where you start to recover from the workout you just finished? It is guaranteed that if you do not cool down and stretch after a strenuous workout you will be in a lot of pain for the next couple of days. Cool-Down - the title speaks for ...
