Obesity & Performance in Physical Activity/Sport
Obesity
Obesity is a term used to describe people with a large fat content, caused by an imbalance of calories consumed compared to energy expenditure. A person is considered obese if they have a body mass index (BMI) of over or over 20% above the standard weight-to-height ratio. If body fat gets to this level it can have serious health implications.

Limits Flexibility: Excess fat around the joints restricts movement
Limits Agility: Excess weight makes it harder to change direction quickly
Limits Speeds/Power: Excess weight makes it harder to move fast
