Are you suffering from dehydration during training?
A lack of hydration during training can cause "global negative mood"
Some interesting research on consuming water through your workout has been published recently in the Perceptual and Motor Skills journal. Conducted by Biological psychologist Kirsten D'Anci, at the prestigious Human Nutrition Research Centre in Aging at Tufts University, the study found that in athletes who consumed NO FLUID during an exercise session reported higher levels of both anger and depression on a mood scale after the session.
After an athletics session they found very slight dehydration of only 1-2 % of body weight (a 0.75 litre loss of fluid in a 75 kg adult) was enough to cause what the researches called a “global negative mood". The symptoms also included signs of confusion fatigue and decreased vigour (energy). The factors were 33% higher than the group that exercised and drank fluid through the session.
The researchers propose that the dehydrated group actually experienced a very slight shrinkage of the brain cells. (Picture a plump green grape versus a dried sultana) this shrinkage causes a chemical imbalance to occur and this affect can increase irritability and potentially trigger headaches.
To ensure you don't fall victim to "global negative mood" and detract from all those good endorphins you produce when you train. Aim to consume 250 mls (a glass) of water every 30 minutes of exercise. This study is important for anyone that exercises and into the lives of people too busy to consume enough water daily.
