The correct answer is ' B, D and E only'

Key Points

1. Sustained muscle contraction (B)

• In static work, muscles contract and hold a position for a long time
• Example: holding a tool or standing still
• There is no movement, but continuous tension in muscles

✔ This is the main defining feature of static work

2. Oxygen independent energy production (D)

• Continuous contraction compresses blood vessels
• This reduces oxygen supply to the muscles
• As a result, muscles produce energy through anaerobic (oxygen-independent) processes

✔ This is a key physiological response in static work

3. Use of glycogen and blood sugar (E)

• Due to limited oxygen, muscles rely on stored energy sources
• Glycogen (stored in muscles)
• Glucose (blood sugar)
• These are broken down to generate energy during static effort

✔ This supports energy production under low-oxygen conditions

Additional InformationA. Increased muscle blood flow** → actually decreases due to muscle compression**

• C. Increased muscle oxygen consumption → oxygen use is restricted, not increased
