Participating in a high energy, classes  such as  SKI CONDITIONING, BODY ATTACK, or any endurance training program , on a LOW CARBOHYDRATE  DIET  is detrimental to improvements in endurance .

A low-carbohydrate intake can have a really disastrous effect on workout quality,

It is well established that carbohydrate is the primary source used above 65% VO2 max, which equates to approx 70-75% HR max, which is the level of intensity you would expect most clients/participants  to be working at , if not higher , in these type of classes.

If a person is following a low-carbohydrate diet and therefore their liver and muscle glycogen stores are low, they will find it very difficult to work at a reasonable intensity during the session and will burn less calories and see less improvement in their fitness levels.

Research shows that low- carbohydrate , may lead to poor movement quality, fatigue, hence increased risk of injury.

It is also important to remember the brain and the central nervous system also rely on carbohydrate fuel,  the brain uses 4-6g glucose every hour and so when blood glucose levels are low, this can cause bad effects on skill , coordination and movement during execution.

So if you are going to join in in a Ski Conditioning class ,or a high energy class, eat some carbohydrate with each meal , and if you are trying to loose some weight, then smaller portions. Exercise drinks are a good option, to maintain energy, and keep your -self  well hydrated.

Or you might find your performance in your Ski Conditioning class/BodyAttack, Tiring ,and unsatisfactionary and wonder why you are on the wrong leg , or going in the  wrong direction !!!
