Muscle protein synthesis and growth

27
Q

Myosin

A

One of the main contractile proteins in muscle fibers

28
Q

Myotatic reflex

A

Neural reflex caused by muscle spindles that enhances the involuntary elastic properties of muscle and connective tissue to increase force production

One of the structural proteins in muscle tissue

30
Q

Neuromuscular junction

A

Junction between the motor neuron and the muscle fibers it innervates

31

A

Stagnation of decrease in performance, increased fatigue, decreased vigor, and hormonal disturbance that can last from weeks to months

32
Q

Osteoblasts

A

Cells in the bone that lay down collagen following damage to the bone from resistance training

33
Q

Osteogenic stimuli

A

Factors that stimulate new bone formation

34

A

A disease where BMD and bone mass are reduced to critically low levels

35
Q

Overreaching

A

Short term detriments to performance following excessive training

36

A

Decrease in health and performance from a combination of excessive frequency, volume, or intensity without sufficient rest, recovery, and nutrient intake

37
Q

Overtraining syndrome (OTS)

A

Prolonged maladaptation of biological, neurochemical, and hormonal regulation mechanisms

38
Q

Parasympathetic overtraining syndrome

Q

Reactive hyperemia

A

Increase in blood flow to the working tissue following a set

46
Q

Selective recruitment

A

Allows advanced lifters to“skip over” the type I fiber recruitment associated with the size principle in order to rapidly generate maximum force by immediately recruiting type II fibers- i.e. Olympic weightlifters

47
Q

Size principle

A

Motor units are recruited in selective order based on recruitment threshold and firing rate.
