Electromyography (EMG)

Electromyography (EMG)

Q1. Create graphs of the muscle activation levels for each protocol (make sure the charts are scaled correctly) using the data provided on CANVAS (use the scatter plot with smooth lines).

Q2. For each push-up protocol: What are the maximal muscle activation values for each muscle? What time did these values occur at?

For the standard push-up protocol, the maximum muscle activation value is at approximately 620 EMG of the lat—triceps at 88 milliseconds.In the comprehensive push-up contract, the maximum muscle activation protocol reads at 750 EMG by the Pect. Major, which occurs at the 84^th millisecond.

Q3. For each squat protocol: What are the maximal muscle activation values for each muscle? What time did these values occur at?

For the standard squat protocol, the maximum muscle activation values read at 20 EMG of Biceps BR, at precisely 68 milliseconds.In the comprehensive squat protocol, the maximum muscle activation value stands at 14.0 EMG of Biceps BR, clicking at 35 milliseconds.

Q4. Compare the different push-up styles (full vs. average width), in terms of muscle activation, using the graphs created in question 3..

It’s hence evident that in each squat protocol, the maximum muscle activation is experienced higher in the full squat compared to the standard squat. Both are, however, affected by the Biceps BR.

Q5. Compare the different squat depths (half vs. full squat), in terms of muscle activation, using the graphs created in question 3.

From the above observations, maximum muscle activation occurs at the comprehensive push-up protocol in comparison to the typical push-up contract.

Q6. What portion of the push-up exercise is concentric, and what part of the push-up activity is eccentric?

The concentric part of the push-up exercise is the standard push-up protocol. This is due to the maximum muscle activation value, which stands approximately 620 EMG of lat. Triceps at 88 milliseconds, while the eccentric part of the exercise is the extensive push-up protocol, following that the maximum muscle activation protocol reads at 750 EMG by the Pect. Major, in a time of the 84^th millisecond.

Q7. Describe the muscle action for each muscle recorded of the push-up during the concentric and eccentric portions.

For the concentric portion, the standard push-up protocol is experiencing maximum muscle activation value of approximately 620 EMG of lat. Triceps at 88 milliseconds and full push-up750 EMG by the Pect. Significant at the 84^th millisecond.An eccentric portion, the standard squat protocol gives a maximum muscle activation values standing at 20 EMG of Biceps BR, at precisely 68 millisecondsGUO, &XUE, 2018).In the comprehensive squat protocol, the maximum muscle activation value stands at 14.0 EMG of Biceps BR, clicking at 35 milliseconds and 14.0 EMG of Biceps BR detailed squat protocol, the maximum muscle activation value stands at 14.0 EMG of Biceps BR, clicking at 35 milliseconds.

Q8. What portion of the squat exercise is concentric, and what part of the squat exercise is eccentric?

The eccentric portion of the squat is the maximum muscle activation that occurs at the comprehensive push-up protocol, while the concentric part is the slowest muscle activation that occurs at the typical push-up protocol.

Q9. Describe the muscle action for each muscle recorded of the squat during the concentric and eccentric portions.

The concentric portion, the typical push-up protocol, is experiencing maximum muscle activation value of approximately 620 EMG of lat. Triceps at 88 milliseconds and full push-up 750 EMG by the Pect. Significant at the 84^th millisecond (Keyserling, 2015).An eccentric portion, the standard squat protocol gives a maximum muscle activation values standing at 20 EMG of Biceps BR, at precisely 68 milliseconds.In the extensive squat contract, the maximum muscle activation value stands at 14.0 EMG of Biceps BR, clicking at 35 milliseconds and 14.0 EMG of Biceps BR comprehensive squat protocol, the maximum muscle activation value stands at 14.0 EMG of Biceps BR, clicking at 35 milliseconds.

Q10. How would you (the practitioner) incorporate EMG? Include the motion/activity you desire, muscles you want to examine, and WHY. (Hint: think about the benefit of knowing the muscle activation patterns for a given motion)

The eccentric portion of the squat is the maximum muscle activation that occurs at the full push-up protocol, while a concentric portion is the slowest muscle activation that occurs at the typical push-up protocol(Wilcox, 2014).
