Nutrition: a determining factor for performance | Nutrisens

Exercise is vital for your body. It improves oxygen supply, gets all the vital organs working and makes you feel better.

Whether you’re an amateur or a seasoned pro, looking to improve your performance or just want to feel good, sports nutrition makes perfect sense!

Here is a list of ingredients that contribute to your success:

  • Your favourite gear (watch, outfit, bike, shoes, helmet, etc.)
  • Your disciplined training
  • Your healthy diet
  • Your sports nutrition before, during and after your workout

Nutrition SportiveWhat you eat directly affects your performance. Other than covering your body’s physiological needs, a good diet and the right sports nutrition during your workout also help to keep you in tip top health and protect against mineral deficiency, sluggish tiredness and cramps, among other things.

This is why we have targeted and examined athletes’ needs and designed products using the ingredients required (glucose, protein, vitamins, etc.). They contain just the right dose of everything an athlete needs.

Did you know? The average sedentary person needs 1800 kcal per day. Athletes need at least 2000 kcal to begin with, plus whatever their daily activities require*:

  • A day in the office: an extra 150 to 200 kcals
  • 1 hour of moderately-paced exercise: an extra 500 to 600 kcals
  • 1 hour of fast-paced exercise: an extra 900 to 1100 kcals

For our metabolism to work correctly, it needs:

  • Carbohydrates (sugar) for optimal energy intake
  • Protein to help muscles function properly
  • Lipids to provide energy during long workouts
  • Vitamins to help ensure an energetic metabolism
  • Minerals to help the body synthesize nutrients
  • Water to ensure good hydration
  • Other plant-based substances to boost the system, antioxydants to keep fatigue at bay...

We’re here to guide you and help you choose the right energy product. Our aim: to help you prepare well BEFORE your workout, perform well DURING your workout and recover well AFTER your workout.

Diététique SportiveWe need an average of 80g of sugar per hour when we exercise. Our body can absorb 50g per hour; so it takes the remaining 30g from our glycogen stores, which is why it’s important to make sure it’s well stocked beforehand. Our glycogen stores then need to be topped up with one energy bar or gel every hour, along with one or two sips of an energy drink every 10 to 15 minutes.

Once the workout is over, the body is still active and needs nutrients. During exercise, your metabolism is really put through its paces: we use our tendons, muscles and joints. Your body needs to rebalance and eliminate the toxins that have built up. To do this, you need an intake of between 7 and 20g of protein, along with carbohydrates, in the 30 minutes after your workout.
