6 Responses Endocrine System

Which hormone is primarily responsible for the 'fight or flight' response during a single session of intense exercise?

• Oestrogen

• Adrenaline

• Testosterone

• Insulin

Testosterone has a direct effect on which system during and after exercise?

• Digestive system

• Nervous system

• Respiratory system

• Muscular system

Which hormone is known to stimulate protein synthesis and muscle repair following a single session of resistance training?

• Oestrogen

• Cortisol

• Testosterone

• Noradrenaline

What is the primary effect of human growth hormone (HGH) during exercise?

• Increases fat breakdown and supports tissue growth

• Decreases heart rate

• Reduces bone density

• Inhibits muscle growth

Oestrogen plays a significant role in which aspect of the skeletal system during exercise?

• Increases bone resorption

• Promotes bone formation and maintains bone density

• Decreases calcium absorption

• Weakens ligaments

During a single session of high-intensity sport, which hormone helps to mobilise energy stores by increasing the breakdown of glycogen?

• Adrenaline

• Oestrogen

• Insulin

• Melatonin

What is a key effect of increased testosterone levels following resistance exercise?

• Decreased muscle mass

• Increased protein synthesis and muscle growth

• Reduced bone density

• Lowered metabolic rate

Which hormone is most associated with the acute increase in heart rate during exercise?

• Oestrogen

• Adrenaline

• Cortisol

• Human growth hormone (HGH)

How does oestrogen affect the skeletal system during a single session of exercise?

• Increases bone breakdown

• Causes muscle fatigue

• Supports bone strength and reduces risk of injury

• Inhibits calcium absorption

Which hormone is released in greater amounts during prolonged endurance exercise to help maintain blood glucose levels?

• Cortisol

• Oestrogen

• Testosterone

• Insulin
