Effects of Exercise on Health

The video explains the long-term effects of regular exercise on the body, focusing on changes in the musculoskeletal and cardiorespiratory systems. It highlights how weight training can lead to muscular hypertrophy, increased bone density, and stronger ligaments and tendons, reducing injury risk. Aerobic exercises improve heart efficiency, lower resting heart rate, and enhance lung capacity, allowing for better oxygen supply to muscles. These adaptations result in greater fitness and endurance.

What is the primary focus of the video?

• Mental benefits of exercise

• Dietary effects on exercise

• Long-term effects of exercise

• Short-term effects of exercise

What is muscular hypertrophy?

• Increase in bone density

• Decrease in muscle strength

• Decrease in muscle size

• Increase in muscle size and strength

What activity is mentioned as increasing bone density in the legs?

• Running

• Swimming

• Cycling

• Squats

What is one benefit of stronger ligaments and tendons?

• Better balance

• Fewer injuries

• Improved speed

• Increased flexibility

What happens to the resting heart rate after six weeks of aerobic training?

• It stays the same

• It fluctuates

• It increases

• It decreases

What is cardiac hypertrophy?

• Decrease in heart size

• Increase in heart size and strength

• Increase in lung capacity

• Decrease in stroke volume

What is the effect of increased stroke volume at rest?

• Heart rate decreases

• Heart rate increases

• Less blood is pumped out per beat

• More blood is pumped out per beat

What happens to the diaphragm and intercostal muscles with regular exercise?

• They weaken

• They stay the same

• They become more flexible

• They become stronger

What is increased capillarization?

• Increase in lung capacity

• Decrease in oxygen diffusion rate

• Increase in the number of capillaries surrounding the alveoli

• Decrease in the number of capillaries

What is the overall benefit of the long-term effects of exercise?

• Greater fitness

• Improved mental health

• Better diet

• Greater flexibility
