Chapter 5 - Adaptations to Anaerobic Training Programs

Question 1

Anaerobic Alactic System is also known as:

Answer 1

The Phosphagen or Creatine Phosphate System.

Question 2

The Anaerobic Lactic System is also known as:

Answer 2

The Glycolytic System

Question 3

The _____ ______ activity increases when the level of force developed increases and when new exercise or movements are being learned.

Answer 3

Motor Cortex

Question 4

Many neural changes with anaearobic training take place along the descending ______ ______.

Answer 4

Corticospinal Tracts

Question 5

Maximal strength and power increases of agonist muscles results from an increases in (3):

Answer 5

1. Recruitment
2. Rate of Firing
3. Syncronization of Firing

*Or a combination of all three factors.

Question 6

Low-threshold motor units are recruited first and have lower force capabilities than higher-threshold motor units.

Typically, to get to high-threshold motor units, the body must first recuit the lower-threshold motor units.

Exceptions exist, especially with respect to explosive, ballistic contractions that can selectively recruit high-threshold units to rapidly achieve more force and power.

Answer 6

Size Principle

Question 7

The muscle undergoing unilateral resistance training produces strength and neural activity in the contralateral resting muscle.

Answer 7

Cross-education

Question 8

The process of ______ involves both an increase in the synthesis of the contractile proteins (actin and myosin within the myofibril) an an increase in the number of myofibrils within a muscle fiber.

The new myofilaments are added to the external layers of the myofibril, resultin in an increase in its diameter.

Answer 8

Hypertophy
