When it comes to eating before swimming, it seems that a lot of us have been fed a lie. You’ve probably been told at some point in your life that you shouldn’t take the plunge until at least thirty minutes after you’ve had food, in case you get cramp, right? Wrong.
There’s actually no evidence to suggest that exercising after eating will give you cramp, although it may be uncomfortable and possibly even make you feel slightly nauseous if you still have half-digested food in your stomach, as blood flow is redirected to your muscles.
So, whilst we aren’t suggesting you have a full three-course meal right before you’re about to strip off, there’s no need for a blanket ban on eating before swimming. Like with every other physical activity, to get the most out of your body, you need to think about what you’re putting in to it.
Whether you’re already a regular visitor to the lanes, or only just considering diving into the deep end — these are our best supplements to power your performance in the pool.
Supplements To Have Before Swimming
Swimming uses a lot of energy — so you need to start with plenty of fuel in the tank. Studies have shown that swimmers need carbs… and lots of them.1,2 Research done with twelve highly trained male swimmers even found that some experienced chronic muscular fatigue as a result of not having enough carbohydrates to match the energy demands of heavy training.3
Our Instant Oats are a perfect, fuss-free solution to packing them in — with 62g of carbs per serving. They’re milled Scottish oats in an ultra-fine powder, so can be mixed with water or milk for porridge, or just as easily added to your shakes and smoothies.
Plus, they’re low in sugar, high in fibre, and have 11g of protein per serving too, which helps to grow and maintain muscle mass — just what you need to power your butterfly.
Caffeine is a super-effective pre-workout ingredient that’s been shown to delay fatigue4 and allow athletes to train with more power, for longer.5 A study in the British Journal of Nutrition found that when a group of sprint swimmers were given caffeine before a 50m swim and a 45 second power test, they were faster and had a higher peak power than the group who were given a decaf placebo.6
Our powerful Caffeine Pro™ tablets are ideal to give you that buzz without the calories or hassle of queuing for a coffee. And no one wants to feel a grande-latte-to-go sloshing about as soon as they get going with front crawl.
Creatine is another tried and tested supplement that’s been proven to increase physical performance in successive bursts of short-term, high-intensity exercise.7 In simple terms, this is because creatine is a chemical compound that supplies the muscles with energy in the form of ATP, which is used rapidly during exercise. More creatine = more energy = more power for you!
Swimming is a sport that requires lots of power — you have to push your body against water to move forward, and you can feel the resistance of it pushing back.
A study carried out with 18 male and female junior competitive swimmers found that the group who had been given creatine over the course of nine days of training were swimming significantly faster, with a significantly decreased swim time in their 100m sprints, compared to the group given a placebo.8
Put creatine to the test for your own length time — we have a range of high-quality supplements for you to choose from, from super-convenient Creatine Monohydrate tablets, to finely micronised Creapure® powder.
Best Supplements For During Your Swim
Need a pick-me-up during an early morning session? These little sachets are the perfect poolside companion, as you won’t even have to get out of the water to enjoy them — no mixing or prep required, all you have to do is squeeze this gel straight into your mouth.
Loaded with 25g of carbohydrates, our Energy Elite™ packs also contain an electrolyte blend to help replenish the essential salts you lose through sweat, along with a vitamin B matrix to reduce tiredness and fatigue. Good things come in small packages.
Hydration is absolutely key to any sport or physical activity, and it’s really important that you stay topped up during swimming. This includes replacing the electrolytes you lose through sweat, as well as water, which is where our Electrolyte Powder comes in.
It’s a blend of four essential electrolytes — sodium, potassium, calcium, and magnesium — which are vital to provide the electrical energy needed for many important functions in the body, including nerve reactions and muscle function.9 Just add a scoop to your water bottle and sip away.
Supplements To Have After Swimming
As much as that vending machine in the reception is calling to you, your body needs something a bit more substantial than a packet of crisps. Pack one of these bad boys in your kit and you’ll have something to bite into before you even leave the changing rooms.
A delicious combination of dried fruit, grains, and honey, each Energy Bar Elite provides a huge 39g of both simple and complex carbohydrates — ideal for refuelling and helping muscle recovery.10
Studies have shown that supplements which combine carbohydrates and protein are most effective at replenishing muscle glycogen after exercise,11 which is exactly what this hard-hitting blend delivers.
Recovery XS is packed with 28g of protein per 100g to support the growth and maintenance of muscle mass, along with 47g of carbohydrates from waxy maize starch and maltodextrin, ideal for muscle recovery.10
It also contains creatine and essential amino acids L-leucine and L-glutamine, which are involved in muscle protein synthesis, 12,13 further supporting your recovery. It’s the perfect post-swim shake.
And last, but definitely not least, keeping on top of your vitamins is super-important for your swim performance, as they help you stay fit and healthy enough to return to the pool. Our Daily Vitamin tablets are a quick and convenient way to make sure you’re hitting your recommended daily intake for seven essential vitamins — supporting your immune system, nervous system and metabolism.
Plus, vitamin C and E are both antioxidants, which means that they can help to reduce skeletal muscle damage and inflammation after strenuous exercise. A study in Sports Medicine on the role of antioxidant vitamins in the prevention of exercise-induced muscle damage concluded that these vitamins could be recommended to those performing regular, heavy exercise.14
