Final answer:
The rectus femoris is active during both the swing and stance phases of the gait cycle. Hypotheses regarding its activity can be confirmed by analyzing the data collected through electromyography (EMG). The data may align with or differ from the hypotheses based on the level of activity observed in the rectus femoris.
Step-by-step explanation:
The rectus femoris is a muscle located in the front of the thigh and is one of the four muscles that make up the quadriceps.
During the gait cycle, the rectus femoris plays a role in both the swing phase and the stance phase. In the swing phase, it contracts to flex the hip and extend the knee, allowing for the leg to move forward. In the stance phase, it stabilizes the knee and helps control knee extension.
Based on this information, you can hypothesize that the rectus femoris would be active during the swing phase when the leg is moving forward, as it is responsible for flexing the hip and extending the knee. It would also be active during the stance phase to stabilize the knee and control knee extension.
To determine if the hypothesis is confirmed, you would need data on muscle activity during the gait cycle. The data can be collected using electromyography (EMG), which measures electrical activity in muscles. If the data shows increased activity in the rectus femoris during the swing and stance phases, it would confirm the hypothesis.
Without the specific data, it is not possible to say whether the hypothesis is in line with what the data showed. However, if the data showed increased activity in the rectus femoris during the swing and stance phases, it would be similar to the hypothesis.
On the other hand, if the data showed no or minimal activity in the rectus femoris during these phases, it would be different from the hypothesis.
