 ASEP-National Meeting & Conference
NEW! Conference program and abstracts now available. CLICK HERE for a MS Word document. The American Society of Exercise Physiologists is pleased to announce plans for the 10th Annual Meeting on April 10 - 12, 2008 in Duluth, MN. The
first Meeting took place 1998 at The College of St.
Scholastica. The Duluth "Meeting" will be a great opportunity to reflect on a decade of work towards the professionalization of exercise physiology.
The meeting will be held at The Inn On Lake Superior.
ASEP is the only organization dedicated exclusively to the
professional development of exercise physiology. It fulfills an
important ethical responsibility for future growth and credibility of
the profession. The Board of Directors is committed to unifying the profession by developing ethical standards and professional credentials in the practice of exercise physiology.
You are invited! This Meeting will provide the opportunity for Exercise Physiologists to network with their peers, to come together as friends, to present scientific papers on health and fitness, wellness, rehabilitation, athletics, and professionalism, and to be part of the change process in exercise physiology.
We look forward to seeing you in Duluth, MN in April.You may register at the link below.

| Q.) I
am currently interested in motor unit patterns of muscle. What are
motor units and their recruitment patterns, and how does this apply to
muscle contraction? Is there any updated research to be provided?
A.) The
motor unit is comprised of a motor neuron in the ventral root of the
spinal cord, the axon and all the muscle fibers it innervates. There are on average 300 fibers that innervate a single motor neuron, although the range can extend to the thousands.
The main purpose of the motor unit is to transform synaptic input from
the motor neuron into mechanical work by the muscle (1). The motor
neuron can be distinguished by its morphology, excitability, and
distribution of input. In contrast, muscle fibers vary by contraction
speed, force generation, and fatigue resistance. One of the most
important factors in determining motor unit recruitment is the size of
the motor neuron. Henneman (3) describes a strong relationship between size of the motor neuron and the order of activation; known as the size principle.
Size and recruitment order is influenced on input resistance. Ohm's law
states the change in membrane potential is proportional to the input
resistance of the motor neuron. Specifically, small motor units have a high resistive response, and are recruited first
from stimulation. Due to this phenomenon, small motor units are
typically activated before larger motor units, are more fatigue
resistant than larger units. Interestingly enough, the recruitment
order of motor units is essentially the same for isometric and dynamic
contractions, including muscle shortening and lengthening (7).
The
amount of force a muscle applies is dependent on the motor unit
activity and motor unit recruitment. "Rate Coding' describes the rate
at which motor neurons discharge action potentials. Although highly
variable, recruitment and rate coding are influenced by the level of
muscle force and the individual muscle itself (4). However, the
absolute force of a motor unit is not permanent and varies with speed
and type of muscle contraction. Another pattern of motor unit
activation that can influence force is 'synchronization', or the simultaneous activation of numerous motor units
(2). In the classic study by Milner-Brown (5), synchronization of motor
unit discharge is greater in a strength hand muscle, which assumes
gains in strength can evolve from motor unit synchronization. However,
this research was significantly flawed in methodology and design during
EMG assessment, which now has severe limitations. Recently, Semmler and
colleagues (6) found that significant strength gains after 4 weeks of
training were not accompanied by increases in synchronization between
pairs of concurrently active motor units in the hand. This is in
accordance with Yao et al (8) that suggest motor unit synchronization
does not influence maximal force produce by a muscle.
Although
evidence suggests a significant role for neural input in strength
training adaptations, less progress has been made on specific systems
for these adaptations. The size principle appears come about after
training, but the absolute force a muscle applies is dependent on contractile individualism; force and contraction time/speed.
It is still unknown if training can further increase motor unit
recruitment, thus influencing rate coding and/or synchronization.
Because the data are limited, further research is warranted. Future
research should concentrate on these specific areas to further identify
relationships between adaptations, motor units activity, and muscle
form and function.
