Question

Describe the effect that the speed of an exercise has on the posture and technique

Answer 1

If you have a good posture alignment, you have a forward lean which maybe has an effect on speed. Also if you run fast you tend to lean forward. A good posture is very important, since a bad posture increases the risks of injury when you run.
I hope this helps.

Answer 2

• Slow speed: allows the use of a more precise technique and allows proper and aligned posture.
• Fast speed: The technique is often more inaccurate and there are high risks of improper and misaligned posture.

Step-by-step explanation:

The execution speed of the exercise is the time that lasts the eccentric and concentric phase of the movement. For both weight loss and hypertrophy, slower speed is more recommended in both phases of execution. The slower, the longer the muscle contracts, thus generating more micrioles in the muscle and spending more energy (ATPs) for the entire process.

In addition, slower speeds allow the individual to use a more accurate and correct technique, as well as allowing the individual's posture to be straight and aligned, avoiding spinal problems.
