BTEC SPORT Revision- muscular system effects of single exercise session

The video discusses the effects of exercise on the muscular system, focusing on immediate changes such as increased blood supply, muscle temperature, and pliability. It explains anaerobic exercise's role in lactate production, leading to discomfort and fatigue. The video also covers microtears and delayed onset muscle soreness (DOMS), emphasizing the importance of warming up to mitigate these effects. Eccentric muscle contractions are highlighted as a cause of DOMS, especially during activities like sprinting.

What is the term used to describe the increased flexibility of muscles during exercise?

• Muscle contraction

• Muscle rigidity

• Muscle fatigue

• Muscle pliability

What byproduct is created during anaerobic exercise that can lead to discomfort?

• Lactic acid

• Oxygen

• Glucose

• Carbon dioxide

What are microtears in muscles, and how do they occur?

• Large tears in muscle fibers due to low-intensity exercise

• No tears occur in muscles during exercise

• Complete muscle tears due to lack of exercise

• Small tears in muscle fibers due to high-intensity exercise

What does DOMS stand for?

• Direct Onset of Muscle Soreness

• Direct Onset of Muscle Strength

• Delayed Onset of Muscle Soreness

• Delayed Onset of Muscle Strength

Which type of muscle contraction is typically associated with causing DOMS?

• Static contraction

• Eccentric contraction

• Isometric contraction

• Concentric contraction
