Importance of nutrition and hydration in sport

Importance of nutrition and hydration in sport

It is well established that eating a healthy and balanced diet can support your general health and wellbeing, but a healthy diet is also very important during physical activity. Whether you are an elite athlete, weekend sport participant or just want to remain fit and active, an appropriate dietary intake is important for you to achieve your full potential. This includes consuming adequate fluids for hydration.

Did you know how important your hydration status is during physical activity?

During exercise, sweat output may exceed fluid intake, which could result in dehydration. If dehydration increases, this can impact your physical and mental health.1 Therefore, it is important to consume appropriate fluids before, during and after your training session.
