Do we slow down as we get older?

What happens to our muscles as we grow older?

• They become stronger

• They remain the same

• They weaken

• They disappear

Answer explanation

As we age, muscle mass and strength typically decline due to factors like hormonal changes and decreased physical activity. This weakening of muscles is a common aspect of the aging process.

Why may older people feel less energetic?

• Because of their diet

• Due to changes in their body and activity levels

• Because they exercise too much

• Because of changes in the weather

Answer explanation

Older people may feel less energetic due to changes in their body, such as muscle mass and metabolism, as well as reduced activity levels, which can lead to decreased stamina and energy.

What does cartilage do for our joints?

• It connects muscles to bones

• It makes our muscles strong

• It cushions our bones

• It holds bones tightly together

Answer explanation

Cartilage acts as a cushion between bones in our joints, reducing friction and absorbing shock during movement. This helps protect the bones and allows for smooth joint function.

How can cartilage wearing away affect a person?

• It increases energy levels

• It makes moving easier

• It causes joint pain or stiffness

• It improves posture

Answer explanation

Cartilage wearing away leads to increased friction in joints, resulting in joint pain or stiffness. This is a common issue in conditions like osteoarthritis, making movement difficult and uncomfortable.

What term describes stiffness in joints commonly found in older people?

• Flexibility

• Agility

• Joint stiffness

• Elasticity

Answer explanation

The term 'joint stiffness' specifically refers to the reduced flexibility and increased tightness in joints, which is commonly experienced by older individuals. This distinguishes it from other terms like flexibility and agility.

How does regular exercise benefit older adults?

• It reduces energy levels

• It improves muscle strength and flexibility

• It increases joint stiffness

• It decreases bone density

Answer explanation

Regular exercise benefits older adults by improving muscle strength and flexibility, which helps maintain mobility and reduces the risk of falls. The other options incorrectly suggest negative effects.

What is a common effect of aging on bone density?

• Bone density doubles

• Bone density decreases

• Bone density remains unchanged

• Bone density increases significantly

Answer explanation

Aging commonly leads to a decrease in bone density due to changes in bone remodeling processes. This makes bones weaker and more susceptible to fractures, making 'bone density decreases' the correct choice.

What is a potential benefit of maintaining a balanced diet for older adults?

• Reduced bone density

• Decreased muscle mass

• Improved energy levels

• Increased joint stiffness

Answer explanation

Maintaining a balanced diet can lead to improved energy levels in older adults, helping them stay active and engaged in daily activities, which is essential for overall health and well-being.
