Question

Heyyyy!!!!!! I really need help with this fast if anyone can help me I really would appreciate it :)

Imagine that you are a biceps muscle. Thinking about what you have learned in this lesson, what forms of energy are displayed when the arm you are in does curls — moves the forearm from a horizontal position up until it is nearly vertical and then down again to horizontal? What factors will affect your reps, and how?

Answer 1

As a biceps muscle, the forms of energy that are displayed when the arm does curls are mechanical energy, potential energy, and kinetic energy. When the arm is curled upwards, potential energy is stored in the muscle, which is then converted into kinetic energy as the arm is lowered back down.

There are several factors that can affect the number of reps a biceps muscle can do. One major factor is fatigue, which can be caused by the buildup of lactic acid in the muscle, and can lead to a decrease in muscle performance. Another factor is muscle strength, which can be affected by factors such as age, gender, and training status. A well-trained individual will typically be able to perform more reps than an untrained individual.

Additionally, factors such as nutrition, hydration, and rest can also affect the ability of the biceps muscle to perform curls. Proper nutrition and hydration can provide the necessary energy and nutrients for the muscle to function optimally, while adequate rest and recovery can allow the muscle to repair and grow stronger.

Step-by-step explanation:

Answer 2

The forms of energy displayed during arm curls are mechanical energy and potential energy. Mechanical energy is exhibited when the muscles contract and move the weight. Potential energy is the energy stored in the weight due to its position relative to the ground.

Several factors affect the number of reps one can do during arm curls. The weight of the object being lifted is the primary factor. The heavier the object, the fewer repetitions one can perform. The strength and stamina of the individual performing the curls also play a significant role. Proper technique, breathing, and rest periods between sets can also impact the number of reps one can do. Other factors that can affect reps include age, health, and nutritional status.
