Question

which of the following influences on skill-related fitness cannot be applied or changed to improve fitness levels?
a. heredity
b. practice
c. specificity
d. none of the above

please select the best answer from the choices provided.

○ a
○ b
○ c
○ d

Explanation:

To determine the answer, we analyze each option:

• Option A (heredity): Heredity refers to the genetic traits we inherit from our parents. These genetic factors (like body type, muscle fiber composition) that influence skill - related fitness are fixed and cannot be changed. We are born with them, and there's no way to alter our genetic makeup to improve fitness in this context.
• Option B (practice): Practice is a key factor in improving skill - related fitness. Through repeated practice, we can enhance skills such as coordination, agility, and reaction time. For example, a basketball player can improve their shooting accuracy through regular practice.
• Option C (specificity): The principle of specificity means that to improve a particular skill - related fitness component, we need to perform exercises that are specific to that component. We can apply and adjust our training programs based on this principle to target and improve different aspects of skill - related fitness. For instance, if we want to improve our speed in running, we can design specific sprint - based training routines.

Since heredity is the factor that cannot be applied or changed to improve fitness levels, the correct answer is A.

Answer:

A. heredity
