Question 1

Strength is best developed at an intensity of 60 percent of 1 RM.
6 T 7. To develop muscular strength in the beginner, the American College of Sports Medicine
(ACSM) guidelines recommend a range between 8 RM and 12 RM.

Accepted Answer

To best develop strength, the intensity typically needs to be at least 70-85% of 1RM for most individuals, according to the American College of Sports Medicine (ACSM) guidelines.

Question 2

As long as women are able to train as hard as men, women can achieve the same amount of muscle hypertrophy (size) as men.

Accepted Answer

Men typically have higher levels of testosterone, a key hormone in muscle growth, which allows them to achieve greater muscle hypertrophy compared to women under similar training conditions.

Question 3

A benefit of strength training, accentuated even more when combined with aerobic exercise, is a(n):

Accepted Answer

Strength training, especially when combined with aerobic exercise, leads to a decrease in adipose tissue (body fat) around muscle fibers, contributing to improved muscle definition and overall body composition.

Question 4

An increase in the size of a cell is called:

Accepted Answer

Hypertrophy refers to the increase in the size of an organ or tissue through the enlargement of its cells.

Question 5

Pilates exercises are performed in a slow, controlled, and precise manner on a mat (floor) or specialized equipment to help increase strength and flexibility of deep postural muscles.

Accepted Answer

Pilates exercises focus on slow, controlled, and precise movements, often performed on a mat or using specialized equipment, to enhance strength, flexibility, and stability, particularly targeting the core and deep postural muscles.

Question 6

To achieve significant strength gains, a minimum of 8 weeks of consecutive training is necessary.

Accepted Answer

Significant strength gains typically require consistent training over a period of time, and research has shown that 8 weeks is a common duration to start observing noticeable improvements in strength due to adaptations in muscle and neural systems.

Question 7

A strong core allows a person to perform daily activities with ease.

Accepted Answer

A strong core enhances stability, balance, and overall functional movement, making it easier to perform daily activities and reducing the risk of injuries.

Question 8

Variations in the extent of masculinity and femininity are determined by individual differences in hormonal secretions of all of the following EXCEPT:

Accepted Answer

Insulin is a hormone primarily involved in the regulation of glucose levels in the blood and is not directly involved in determining variations in masculinity and femininity, unlike androgens, progesterone, and testosterone, which are directly involved in sexual development and characteristics.

Question 9

_____ might be the most important health-related component of physical fitness in the older adult population because of its contribution to independent living.

Accepted Answer

Muscular strength is crucial for older adults as it helps maintain independence by enabling them to perform daily activities such as lifting objects and getting up from a chair.

Question 10

For the beginner, long-term strength training often leads to the decrease of _____ more than the increase of muscle mass.

Accepted Answer

For beginners in strength training, the initial changes often include a more significant decrease in fat mass as the body starts to burn fat for energy, rather than a substantial increase in muscle mass, which takes longer to develop.

Question 11

Fast-twitch fibers generate more force than slow-twitch fibers.

Accepted Answer

Fast-twitch fibers are designed for power and speed, generating more force for short bursts of activity compared to slow-twitch fibers, which are designed for endurance and sustained activities.

Question 12

Good strength enhances quality of life by reducing the:

Accepted Answer

Good strength enhances quality of life by reducing the risk for injuries and falls, as stronger muscles provide better support and stability.

Question 13

Muscular endurance is best tested using maximal exercise.

Accepted Answer

Muscular endurance is best tested using submaximal exercises that measure how long a muscle group can perform a specific action, rather than maximal exercises which test strength.

Question 14

Each additional pound of muscle tissue in older adults increases resting metabolism by:

Accepted Answer

The answer of Each additional pound of muscle tissue in...

Question 15

The appearance of heavy musculature of a female body builder during competition is a result of:

Accepted Answer

The answer of The appearance of heavy musculature of a...

Question 16

Proper cardiorespiratory endurance contributes more to independent living than any other fitness component.

Accepted Answer

The answer of Proper cardiorespiratory endurance contributes more to independent...

Question 17

Which of the following statements is TRUE?

Accepted Answer

The quality of muscle tissue between men and women is essentially the same, with differences in muscle size and strength largely attributed to hormonal differences and body composition rather than muscle quality itself.

Question 18

A motor unit is the motor neuron and the muscle fibers it innervates.

Accepted Answer

A motor unit consists of a single motor neuron and all the muscle fibers it innervates, allowing for the coordination of muscle contractions.

Question 19

Which of the following statements is TRUE?

Accepted Answer

Hormonal differences, particularly lower levels of testosterone in women compared to men, mean that women generally cannot achieve the same extent of muscle hypertrophy as men.

Question 20

Lean body mass decreases with _____, which, in turn, slows down the resting metabolic rate.

Accepted Answer

Lean body mass decreases with sedentary living because a lack of physical activity leads to muscle atrophy and a reduction in muscle mass, which can slow down the resting metabolic rate.

Quiz 7: Muscular Strength and Endurance

Strength is best developed at an intensity of 60 percent of 1 RM. 6 T 7. To develop muscular strength in the beginner, the American College of Sports Medicine (ACSM) guidelines recommend a range between 8 RM and 12 RM.
