REDUCING CHOLESTEROL THROUGH SWIMMING AND TRIATHLON

22/11/2022

​As most people know, swimming is an excellent form of aerobic exercise. Whether its performing distance training in the pool (or even taking a Strictly Swimming London lesson), it helps strengthen the heart by increasing blood flow and helping it to even increase in size.

Swimming is also one of the best forms of exercise when it comes to increasing efficiency of the heart in pumping blood around the body. This increase of good blood flow has a fantastic impact on reducing bad cholesterol on both men and women adult swimmers.
 
What is cholesterol?
​

Cholesterol is a fatty, waxy substance which is vital for your body to function day to day. A small amount of cholesterol is healthy, as it forms part of the cell walls and is also necessary to create hormones.
 
What are the two different types of cholesterol?

There are two main types of cholesterol – LDL (Low Density Lipoprotein) or ‘bad’ cholesterol and HDL (High Density Lipoprotein) or ‘good’ cholesterol. HDL cholesterol is beneficial to the body. As adults, through our diets and lifestyles, LDL cholesterol can build up and fatty deposits can develop along the walls of arteries. Over time this causes the arteries to become narrow and blocked, reducing blood supply to the heart.

This process is called atherosclerosis and can eventually cause symptoms of angina or even result in a heart attack or stroke. One cause of high LDL cholesterol is a diet high in saturated fat. The fat in the food that we eat is then digested and taken to the liver, where it is metabolised into cholesterol.
 
HDL cholesterol, however, helps remove other forms of cholesterol from your bloodstream and are associated with a lower risk of heart disease. HDL picks up excess cholesterol in your blood and takes it back to your liver where it's broken down and removed from your body.
 
Benefits of Swimming on your Cholesterol

  1. Swimming definitely increases good cholesterol. By increasing your HDL cholesterol by 1%, the risk of dying from heart disease reduces by 3.5%
  2. The fat burning properties of swimming 30 minutes or more (or even during your Strictly Swimming London lesson) will reduce your dangerous cholesterol
  3. Some studies show that swimming boosts your metabolism more than most sports and increase good cholesterol more than most sports.
  4. A 30-minute workout in the water is comparable to 45 minutes of land-based exercise due to the added resistance of the water against your body
  5. Many studies show that aerobic swimming is an excellent way of keeping your arteries open, flexible and in good shape.
  6. Many people who take up triathlon are also looking to reduce their bad cholesterol as they age.
  7. Swimming training at only moderate intensity, significantly reduces total cholesterol 
  8. If you are an open water swimmer, a recent study showed excellent evidence that cold water swimming decreases LDL cholesterol. The extreme cold water increased blood circulation dramatically (through increased metabolism) and this in turn helped decreasing their bad cholesterol.
 
If you're already a swimmer or participate in triathlons, you've will have discovered the benefits of swimming already. If you aren't, it's never too late to learn how to swim or to brush up on strokes that you learned as a kid. Our Strictly Swimming London coaches can even tailor your lesson to develop aerobic swim training during your lesson.

​As an adult who may be concerned about cholesterol, just remember swimming ultimately prevents heart disease!!!

WHY YOU SHOULD KEEP HYDRATED DURING YOUR SWIM TRAINING

10/11/2022

There is a common misunderstanding that swimmers don’t need to hydrate as much as land-based sports people as we don’t sweat as much in the water. Sure, studies have shown that we sweat less in the pool, however, this does not mean that we do not dehydrate during swim training.

In fact, there are many good reasons why we should maintain hydrating during our workouts, triathlons, and open water swims. You may hear Strictly Swimming coaches consistently harp on the need to hydrate before, during, and after practices. Hydrating is vital to the success of all swimmers.

We need water to survive obviously. Every cell in our bodies needs water to function properly. It helps carry nutrients and boosts energy, flushes waste products and is vital to maintain body temperature during swimming workouts or at rest. In fact, during exercise generally, water is much more important as more energy and fuel is being used. Even though you may feel cool in the pool or open water, there is an actual rise in body temperature, hence the reason to keep hydrating during your swimming lesson.

​The cold temperature of the water does cool the body down and sweating is reduced, however, the body will still dehydrate due to high muscle activity. It is very easy to miss that you are dehydrating when swimming due to the cool water temperature, so it is more important to swimmers to keep an eye on their water intake during a workout. Make sure you have your full water bottle at the end of the pool during practice .

Here are some key physiological reasons to maintain hydration:

  1. The body will recover faster and you will be able to workout at a higher level for longer. Our muscles require water to function and repair during and after a swimming workout.
  2. Our muscles functions better as water is vital in transporing blood.
  3. Prevents cramping during your swim workout
 
What to drink when swimming
​

Water is the best drink to quench thirst and replace fluids lost during exercise. Drink water before you start your swimming lesson. Water boasts a huge list of benefits. It’s natural, free, readily available, contains no calories.

About sports drinks

Some athletes use sports drinks that contain electrolytes and carbohydrates, which have concentrations that allow the body to refuel during exercise. Sports drinks may be useful if your activity is moderate to vigorous in intensity for more than 60 mins, However, sports drinks can be high in sugar, so always check out this out before purchasing. Remember that fruit and vegetables contain a high proportion of water, so a fruit snack (such as oranges) can help your fluid replacement.

What not to drink when exercising

Some fluids are not recommended when exercising:
  • Avoid cordial juices, soft drinks or juices. These are usually high in carbohydrates and low in sodium.
  • Avoid caffeine, which can be a diuretic (which means it makes you pass more urine, and therefore lose more fluid).

How much to drink after exercising

To adequately rehydrate after your swimming session, aim to drink one and a half times the fluid you lost while exercising. You will need to drink more fluid than you lost while swimming because you will continue to lose fluid through sweating and urination for some time after you have finished your workout or lesson.
