Supersized ropes that are typically heavy and long, which are used as a training tool for individuals by using them in motions such as waving, slamming, whipping, etc.

145
Q

excess post-exercise oxygen consumption (EPOC):

A

A measurably increased rate of oxygen intake following strenuous activity intended toerase the body’s oxygen deficit.

146
Q

proprioceptive feedback:

A

Relating to stimuli that are produced and perceived within an organism, especially those connected with the position and movement of the body.

147
Q

cross-training:

A

Refers to a style of training in which individuals engage in various types of sports or exercises in order to gain a well-rounded health and muscular development.

148
Q

compound exercises:

A

Exercises that engage two or more different joints to fully stimulate entire muscle groups and multiple muscles.

149
Q

flexibility:

A

The range of motion around a joint.

150
Q

range of motion (ROM):

A

The movement of a joint from full flexion to full extension.

151
Q

actin:

A

Long, thin contractile filaments.

152
Q

myosin:

A

Short, thick contractile filaments.

153
Q

Z-Iines:

A

Any of the dark bands across a striated muscle fiber that mark the junction of actin filaments in adjacent sarcomeres.

154
Q

sarcomere:

A

A structural unit of a myofibril in striated muscle, consisting of a dark band and the nearer half of each adjacent pale band.

155
Q

sarcoplasmic reticulum:

A

The specialized endoplasmic reticulum of cardiac muscle and skeletal striated muscle that functions especially as a storage and release area for calcium.

156
Q

sarcolemma:

A

The fine transparent tubular sheath that envelops the fibers of skeletal muscles.

157
Q

endomysium:

A

A wispy layer of areolar connective tissue that ensheaths each individual myocyte (muscle fibre, or muscle cell).

158
Q

proprioceptors:

A

Specialized sensory receptors located in tendons and muscles sensitive to stretch, tension, and pressure.

159
Q

Golgi tendon organ:

A

Proprioceptors located at the junction of muscles and tendons that pick up messages of excess stress on the muscle and cause the brain to shut off muscle contraction.

160
Q

Pacinian corpuscles:

A

An encapsulated ending of a sensory nerve that acts as a receptor for pressure and vibration.

161
Q

muscle spindle:

A

Sensory receptors within the belly of a muscle that primarily detect changes in the length of this muscle.

162
Q

goniometer:

A

An instrument for the precise measurement of
angles, especially one used to
measure the angles between the
faces of crystals.

163
Q

Pulley System

A

Another muscular-structural arrangement is the pulley. Pulleys are very common in exercise machines-such as in the lat pull-downs-to create a greater mechanical advantage and to move the limbs freely.

164
Q

Wheel and axle

A

Wheel and axle-like arrangements in the body are needed for the transmission of force. A good illustration of this arrangement is shoulder joint medial and lateral rotation.

165
Q

Pushing:

A

In some compound (multi-joint) exercises, rather than solely using a rotary component to move the weight, you use a push pattern in which the hands or feet move in a straight line.

166
Q

Pulling:

A

Pulling is the opposite of pushing. The hands or feet move in a straight line while two or more joints are in rotary action. For example, in the seated row, your body is stable and your hands move in a straight line as you pull them in toward the body.

167
Q

Benefits of good posture:

A

Good posture is important to health. It is needed in order to keep the organs in place and to allow them to work efficiently and effectively.

168
Q

Spine:

A

The spine is the keystone of body structure. It must support the weight of the head, trunk, and upper extremities.
