Active Individuals & Sport


Have you ever walked into the gym, had a look around and noticed how seemingly over-prepared some of the patrons are – sports drinks, snack and water… Are you doing something wrong? Do they know something that you don’t? Today I’ll take you through when you need to eat, drink or both during exercise and what exactly you need.

Whether and how much you need to eat and drink during exercise is dependent on various factors, such as the duration, intensity and objectives of the session as well as body composition goals which need to be considered.

In general:

  • Sessions lasting less than an hour (up to 90 minutes for lower intensity exercise) should require nothing more than fluids if the session has been initiated with adequate fuelling.
  • Sessions exceeding 60-90 minutes require refuelling with carbohydrates, this will help to maintain energy levels to keep you performing at your best for longer.

Even slight dehydration can impair your athletic performance, therefore fluid intake should be a major priority for anyone that takes their sport seriously. Fluid requirements during exercise will be dependent on sweat rates, it is also very important to make sure that you are properly hydrated when you start the exercise.

  • Small amounts of fluid are usually required during sessions of exercise lasting less than an hour and thirst can be used as an indicator.
  • For longer sessions planned fluid intake should be actioned to avoid dehydration. In order to better understand your sweat rates it is advisable to weigh yourself before and after exercise, 1kg weight-loss will equate to 1l fluid loss. Requirements will usually vary between 150ml-350ml every 15 to 20 minutes depending on temperature/humidity, intensity etc.

During exercise lasting more than 60-90 minutes, carbohydrates becomes very important to prevent “hitting the wall”, that moment when your body and soul just don’t want to carry on. This is when your body runs out of available glycogen (energy) to fuel performance. Taking in easily digested carbohydrates can prevent this phenomenon from occurring. As a rule we require 30-60 g of carbohydrates per hour, this can further increase to 90 g in events with high levels of effort lasting more than 3-4 hours. Nutrition should be initiated after about 45 minutes and spread out across the hour as well as the particular sport you participate in allows.
Sports drinks can be a great way to contribute to your carbohydrate requirements as they provide both fluid and carbohydrates with electrolytes to promote rehydration.
Practice your nutrition strategies during training because individual tolerance varies and what works for one person may be a disaster for another during a competition.

What does 15g of carbohydrates look like?

  • 1 small banana
  • ¾ FUTURELIFE® High Energy SmartBar
  • ½ – 1 sports gel (read nutritional table for exact nutritionals of each product)
  • 220ml sports drink (7% carbohydrate concentration).
  • +/- 25g jelly sweets
  • 1 slice of FUTURELIFE® Smart Bread™ with Marmite/Bovril (these provide additional electrolytes)

Good nutrition and hydration practices during exercise can do wonders for your performance and quite literally prevent you from “hitting the wall”. Practice your hydration and nutrition during training sessions until you find what works best for you.
