Question

What is correct for a normal running gait cycle?

• A. Two double float subphases of 5% each
• B. One double float subphase of 20%
• C. Two double support subphases of 11% each
• D. One stance phase of 65% of gait cycle

Hint:

Running = No double support, has float phase Walking = Has double support

Answer 1

The Correct Option is A

Concept:
Running gait differs from walking gait:
• Walking → has double support phase
• Running → has double float phase (both feet off ground)

Step 1: Understanding running gait.
In running:
• No double support phase
• Two float phases occur

Step 2: Duration of float phase.
Each float phase occupies approximately:
• 5% of gait cycle

Step 3: Evaluating options.

• Two float phases (5% each) → correct
• One float phase → incorrect
• Double support → present in walking, not running
• 65% stance → walking characteristic

Step 4: Conclusion.
\[ \boxed{\text{Two double float subphases of 5\% each}} \]
