From the list given below which are the indicator of static work
A. Increased muscle blood flow
B. Sustained muscle contraction
C. Increased muscle oxygen consumption
D. Oxygen independent energy production
E. Glycogen and blood sugar is used to produce energy
Choose the correct answer from the options given below :

Correct option is D

Static work refers to muscle contractions where there is little or no movement of the muscle length, meaning the muscle remains contracted for a prolonged period. Unlike dynamic work, which involves continuous movement and relaxation, static work requires sustained muscle contraction, leading to increased muscle tension and physiological changes.
The correct answer is (d) A, B, and D only, because:
· Increased muscle blood flow (A) → Static work requires more oxygen and nutrients, increasing blood flow to the working muscles.
· Sustained muscle contraction (B) → In static work, muscles remain contracted without relaxing, leading to muscle fatigue.
· Oxygen-independent energy production (D) → Since static contractions limit blood circulation, muscles rely on anaerobic (oxygen-independent) metabolism for energy production.
Information Booster:
Key Indicators of Static Work:
1. Muscle remains contracted for extended periods.
2. Limited blood flow due to sustained contraction.
3. Energy production shifts to anaerobic metabolism (without oxygen).
4. Leads to early muscle fatigue due to lactic acid buildup.
5. Common in activities like weightlifting, yoga, and posture maintenance.
Additional Knowledge:
· (C) Increased muscle oxygen consumption → Incorrect, because oxygen supply is limited in static work due to reduced blood flow.
· (E) Glycogen and blood sugar used to produce energy → Incorrect, because anaerobic metabolism (which dominates in static work) does not rely heavily on glycogen breakdown.
