What happens to the body and mind when someone is inactive for too long?
The consequences of a sedentary lifestyle (weight gain, obesity and the health risks it brings), the classification of body weight (underweight, overweight, obese), and the effects of a sedentary lifestyle on physical, emotional and social health.
A focused answer to OCR GCSE PE Component 02 on the consequences of a sedentary lifestyle: the meaning of sedentary, the classification of body weight (underweight, overweight, obese), and the physical, emotional and social health risks of inactivity, including obesity, heart disease and type 2 diabetes.

What this dot point is asking
OCR wants you to define a sedentary lifestyle, classify body weight, and explain the physical, emotional and social consequences of inactivity, including obesity and its health risks.
Defining a sedentary lifestyle
Modern life makes sedentary behaviour easy, which is why inactivity is a major public-health concern and why physical activity is promoted so strongly.
Classifying body weight
Physical consequences
The main physical consequence is weight gain leading to obesity. A sedentary person uses little energy, so if they take in more energy than they use, the excess is stored as fat. Over time this causes overweight and then obesity, which raises the risk of heart disease, high blood pressure, type 2 diabetes, joint and back problems, and some cancers. Inactivity also leads to weaker muscles and bones, poorer cardiovascular fitness, and poor posture and back pain from prolonged sitting.
Emotional and social consequences
Why this matters
The consequences of a sedentary lifestyle are the flip side of the benefits of activity (linking to health and well-being). They are closely tied to energy balance and diet (linking to those topics): obesity results from taking in more energy than is used, so both activity and a balanced diet are needed to maintain a healthy weight and avoid these risks.

OCR 20194 marksDefine a sedentary lifestyle and explain two health consequences it can have.Show worked answer →
A Component 02 item. Award marks for the definition and for two developed consequences.
Definition: a sedentary lifestyle is one with little or no physical activity, involving a lot of sitting (at a desk, watching screens, travelling by car).
Two consequences (any two, developed): weight gain and obesity (if energy taken in exceeds energy used, the excess is stored as fat); increased risk of heart disease (poor cardiovascular fitness and high blood pressure); type 2 diabetes (linked to obesity); poor self-esteem and depression (emotional consequences); weaker muscles and bones; and poor posture and back pain from prolonged sitting.
Markers want a clear definition plus two genuine consequences explained, ideally across more than one dimension of health.
OCR 20213 marksExplain how a sedentary lifestyle can lead to obesity and why obesity is a risk to health.Show worked answer →
A 3-mark item linking inactivity, obesity and health risk.
Award marks for: a sedentary lifestyle means the person uses little energy, so if they take in more energy (food) than they use, the excess is stored as fat. Over time this leads to being overweight and then obese (a very high level of body fat).
Why obesity is a risk: it increases the strain on the heart and raises the risk of heart disease, high blood pressure, type 2 diabetes, joint problems and some cancers, and it can also harm self-esteem.
Markers want the energy-imbalance explanation plus at least one named health risk of obesity.
