Sports Nutrition to increase Endurance, Stamina and Energy Levels

Sports supplements are nutritional products with concentrated levels of nutrients in supplementation of the normal diet and are designed to have a positive effect on sporting performance levels. The effect can either be nutritional or physiological.

Sports Supplements are marketed towards sportspeople with the purpose of improving their sporting performance and it is possible to split them down into three distinct categories

  1. Energy and Endurance
  2. Muscle Mass, Strength and Power
  3. Recovery Post Exercise.

This article will concentrate on sports supplements and nutrition which targets category 1- Energy and Endurance sports supplements.

Isotonic Sports Drinks for Improved Endurance Performance

Isotonic sports drinks help to replace fluid during and after exercise and provide carbohydrate to fuel working muscles.

The presence of electrolytes in these drinks help the body to better retain this fluid and are also considered vital in preventing muscle cramps.

Examples of these products are Gatorade, Powerade, Lucozade Sport, Science in Sport Go Electrolyte, Hammer Nutrition Perpetual and Hammer Nutrition Heed. All of which are Isotonic nutritional products.

Simple Isotonic sports drinks are relative easy to make yourself. You could easily make your own Isotonic sports drinks for during exercise.

Hypotonic Energy Drinks

Hypotonic sports drinks provide higher levels of carbohydrate than the regular- isotonic type sports drinks. These drinks help to maintain blood sugar levels and slow down rates of glycogen depletion.

Examples of these drinks are Science in Sport PSP22, Lucozade Energy and even Coca-Cola can also be used as a Hypertonic energy drink and has been drunk for many years by cyclists on the Tour De France.

Energy Bars, Gels and Other Energy Products

Energy bars provide a convenient source of carbohydrate for athletes before during and after intense exercise.

Energy gels are designed to provide a high concentration of carbohydrate to help delay fatigue and improve performance. Usually they need to be taken with a sufficient amount of fluid however a number of companies are now producing Isotonic Energy Gels which negate the need to consume extra water.

  • Carbohydrates to fuel your body during endurance exercise.
  • Electrolytes which are vital for maintaining fluid balance.
  • Vitamin B1, B2, & B3 to help burn carbohydrates and fat to create energy.
  • Vitamin C to protect muscles and cells against oxidative damage.

Caffeine to improve endurance performance

The general effect of caffeine is to cause arousal of the central nervous system, mobilisation of free fatty acids and other metabolites leading decreased reliance on glycogen stores for energy.

Caffeine is classed as a pharmaceutical compound (drug) as it has no nutritional value for the body.

Caffeine has been shown to significantly improve time to exhaustion in cyclists[1] although amount ingested must be above 200 mg of caffeine to make a significant difference on performance.[2]

The below shows levels of caffeine in various drinks

How much caffeine is in my coffee?[3]

Average cup[i] of instant coffee 75mg caffeine

Average mug[2] of instant coffee 100mg caffeine

Average cup of brewed coffee 100mg caffeine

Average mug of tea 75mg caffeine

Regular Cola drink up to 40mg caffeine

Regular energy drink up to 80mg caffeine (Example Red Bull)

Milk Chocolate Bar up to 25mg caffeine

i. An average cup contains 150-175 ml of liquid.

ii. An average mug contains between 250-300 ml of liquid

Tall (16oz) Starbucks Bold Pick of the Day 260 mg caffeine[4] (See above right)

Too much caffeine can actually diminish performance levels and this drug is not on the WADA banned substances list

Ephedrine / Ma Huang and Endurance performance

Ma Huang, a Chinese herb is a powerful central nervous system stimulant which is often known as herbal ephedrine. It's active compounds include ephedra. Ephedrine is marketed towards endurance sports athletes for increasing endurance capacity however it is banned by the 2011 prohibited list by WADA International Standards. .

The Effect of Ginseng on endurance performance

Despite being taken by many endurance athletes Ginseng has not been proven to have an effect on endurance performance[5] therefore it is not recommended as a sports supplement for endurance athletes. It has not been proven to have an effect on running[5] or cycling performance.

Sports Nutrition and Endurance Performance

Thermogenics for Endurance Sport Performance

Thermogenics (fat burners or diet pills) claim to speed up the body metabolism and therefore help an endurance performance by helping the athlete achieve a lower body mass. This is particularly important in sports where body weight and equipment weight can have an adverse effect on performance such as cycling, particularly when the athlete is racing on hilly and mountainous routes as a reduced bodyweight in relation to strength allows the cyclist to help fight the effects of gravity while climbing. Bicycling nutrition and maintenance of a healthy weight is paramount to achieving optimum performance levels.

Boxers may also resort to using thermogenic fat burning products to help them make a weight for an upcoming fight.

Typical constituents of Fat Burners[6]

The most potent thermogenics utilise ephedrine (or ephedra), a powerful stimulant which increases thermogenesis and metabolic rate to increase calories burnt daily by the athlete. However as described above ephedrine is on the WADA banned substances list and therefore could lead to a failed drug test and therefore should not be recommended.

Green Tea and weight loss for endurance athletes

Ephedrine free fat burners

Regularly found in Ephedrine Free Fat Burners are

Green Tea Extract.

The active compunds in Green tea are polyphenols (catechins) and flavanols. The main catechins include EC- epicatechin, ECG- epicatechin gallate, EGC- epigallocatechin and EGCG- epigallocatechin gallate. These are potent antioxidants and also have been shown to have a mild increase in thermogenesis. Do not expect miracles however as this has only be shown to be less than 100 calories per day. (Although it all adds up!)

Green tea also contains caffeine which can lead to improved endurance performance.

Citrus aurantium

Citrus aurantium is a weak stimulant which is chemically similar to ephedrine. It contains a compund called synephrine. A synthetic ephedrine which has been claimed to raise metabolic rate and suppress appetite.

Coleus forskohlii (Plectranthus barbatus)

Coleus forskohlii (Plectranthus barbatus) produces forskolin which it has been considered stimulates adenyl cyclase (cAMP) activity. Coleus may, theoretically, be a weight loss agent, especially for those with reduced Cyclic AMP production. However it's effectiveness is yet to be proven and previous studies have shown no significant effect on weight loss[7] in short term trials. Therefore Coleus forskohlii has no effect on endurance performance.
