Question

Match the position of feet in Group I to the most appropriate description of stability of human body in Group II. 

Group I 
P \(\text{Position 1: Feet slightly apart in parallel}\)
Q \(\text{Position 2: Feet apart in a wide stance}\)
R \(\text{Position 3: Feet close together with a narrow stance}\)
S \(\text{Position 4: Feet in a wide cross stance}\)

Group II 
1 Stable antero-posteriorly 
2 Laterally stable 
3 Fairly stable in all directions 
4 Vertically stable 
5 Unstable 
 

• A. P–5, Q–5, R–2, S–1
• B. P–5, Q–3, R–1, S–2
• C. P–1, Q–3, R–2, S–2
• D. P–4, Q–2, R–1, S–1

Hint:

When assessing body stability, a wider stance provides better lateral stability, while a narrow stance may provide better vertical stability.

Answer 1

The Correct Option is B

The position of the feet affects the stability of the human body in various directions. Let's analyze the feet positions and their stability:
1. P (Feet slightly apart in parallel): This position provides the least stability and is relatively unstable since the body does not have a strong base of support. It is commonly used in dynamic movements but lacks static stability.
2. Q (Feet apart in a wide stance): This position increases stability laterally, providing a wider base of support, making the body more stable in lateral directions (side-to-side movement). It is a commonly used stance in sports and other activities where lateral stability is important.
3. R (Feet close together with a narrow stance): A narrow stance leads to less lateral stability, making the body less stable in this direction. However, the body is more stable vertically, as the feet form a compact base of support.
4. S (Feet in a wide cross stance): This stance provides good overall stability, including both lateral and vertical, as the body is well supported in multiple directions. It provides the best overall stability of all options.
Thus, the correct matching is: - P corresponds to Unstable (Option 5). - Q corresponds to Fairly stable in all directions (Option 3). - R corresponds to Stable antero-posteriorly (Option 1). - S corresponds to Laterally stable (Option 2). Therefore, the correct answer is (B).
