Q

How does age affect strength and endurance in early childhood and preadolescence?

A

Strength and endurance increase linearly with chronological age. Muscle fiber is determined prior to birth. Boys have slightly greater muscle mass and are about 10% stronger.

Q

What changes occur during puberty regarding muscle fiber size and strength?

A

There is a rapid acceleration in muscle fiber size and muscle mass, increasing more than 30% per year, along with a rapid increase in strength.

  • In boys: muscle mass, body height and weight peak before muscle strength
  • In girls: strength peaks before body weight

Q

How does muscle strength change in late adulthood?

A

The rate of decline accelerates to 15%-20% by the sixth and seventh decades and 30% per decade thereafter. By the 80th decade, muscle mass has decreased by 50% compared to young adulthood.

Q

What is the relationship between sets, repetitions, and intensity of resistance?

A

There is an inverse relationship; lower the load, the greater the number of repetitions and sets.

Q

How can muscle endurance be improved?

A

By performing many repetitions of an exercise against a submaximal load, such as 3-5 sets of 15-30 repetitions.

Q

What factors determine the frequency of exercise sessions?

A

Frequency is determined by intensity, volume, patient goals, health, and response to treatment.

17
Q

Average RM

A
  • Average untrained adult: 75% of 1 RM can complete ~ 10 reps before fatigue
    • At 60% intensity about 15 reps are possible
    • At 90% intensity only 4-5 reps are possible
