Be Happy : Friday’s Health & Fitness Fact

31 May

Sports Drinks are no more hydrating than water!

We see adverts all around us for the latest sports drinks, that promise to ‘revitalise us’, keep us ‘going longer’, and ‘improve performance’ – however do they actually work?

Oxford University Centre for Evidence-Based Medicine conducted various tests to research into claims made by manufacturers of sports drinks and protein shakes, and concluded that the quality of the evidence from the manufacturers was poor, and that the effect of the products was miniscule.

Sugar

In fact many sports drink are so high in sugar that the average fitness-freak doesn’t burn enough calories in a session at the gym to warrant drinking them!

A bottle of Lucozade Energy contains 266 calories – more than a Mars bar – only 260 calories!

Whilst a bottle of Powerade contains as much as seven teaspoons of sugar – similar to that of a can of coke – and you would need to walk for 30 minutes, or run for 15 to 20 minutes to burn it off!

Make your own sports drinks, and say goodbye to unnecessary sugar!

Water is better at hydration than any other liquid, both before and during exercise, however sports drinks may be seen to be more hydrating as you are more likely to drink larger volumes, therefore leading to better hydration!

You should drink 120-170ml of water for every 15-20 minutes of exercise – so an hour’s worth of exercise would require between 480 and 680ml – an average-sized sports drink bottle … But instead of drinking the sweet sugary option, keep that empty bottle before buying another, and make your own – not only a healthier option, but much cheaper too!

 

Isotonic Sports Drink :

  • 100ml fruit squash
  • 400ml water
  • a very small pinch of salt

Mix it all together and chill in the fridge.

An isotonic sports drink is best for :

  • A boost of carbohydrates
  • Long distance/long duration sports and activities
  • Replacing fluids lost through sweat

 

Hypertonic Sports Drink :

  • 200ml fruit squash
  • 500ml water
  • a very small pinch of salt

Mix it all together and chill in the fridge.

A hypertonic sports drink is best for :

  • A boost of carbohydrates – higher level than isotonic and hypotonic drinks
  • After exercise, to help top up muscle glycogen stores
  • For long distance events like marathons
  • Can also be taken during strenuous exercise.

 

Hypotonic Sports Drink :

  • 50ml fruit squash
  • 500ml water
  • a very small pinch of salt

Mix it all together and chill in the fridge.

A hypotonic sports drink is best for :

  • Quickly replacing fluids without adding carbohydrates
  • Drinking straight after a workout, as they directly target the main cause of fatigue – dehydration – by replacing lost water fast.
