Components of physical fitness include:

Physical activity includes:

Types of exercise include:

Benefits of doing physical activity (check if true)

Physical inactivity is associated with:

Aerobic exercise are needed to improve the fitness of the heart and lungs

Effective aerobic exercise need to be frequent, intense and last for at least 10 minutes

Resistance exercises involve muscular forces by moving weights or working against a fixed load

Resistance exercises increases muscular fitness when performed regularly over time

Flexibility exercises increase or maintain the range of motion available at joints

Flexibility exercise involve stretching

After exercise insulin mediated glucose uptake remains significantly increased up to 18 hours depending on the intensity of the previous exercise.

Increased insulin mediated uptake is more prolonged with resistance compared to aerobic exercise

For each component of exercise, there is a minimum intensity below which there will be no benefit

The minimum exercise intensity required for benefit increases as one becomes more fit (stronger, greater endurance)

Consistent training at an appropriate intensity level should result in observable adaptations within six to twelve weeks

Once achieved, a specific training effect, can be maintained at a reduced frequency of training provided the intensity and duration are maintained

Most training benefits are lost within a four to eight week period of sedentary activity

The principles of exercise include:

Risks of exercise include:

Exercise in the absence of insulin may lead to hyperglycaemia and ketosis even without food

Exercise in the presence of insulin may lead to hypoglycaemia even hours after the exercise

Exercise in the presence of oral hypoglycaemic drugs may lead to hypoglycaemia even hours after the exercise

Exercise and alcohol have opposite effects on hepatic glucose metabolism

The output of glucose from the liver decreases after prolonged physical training

The recommended amount of exercise for adults should be at least 30 minutes per day at least 5 days per week

Exercises are not recommended for:
