The Original Gyro Exerciser
Starting Instructions
Your Original
Gyro exerciser is a precision gyroscopic exercise instrument which has
been designed to develop strength and coordination of the wrist, hands,
arms, and upper body. Initially for some people starting the Gyro may be a
challenge and also temporarily frustrating because you must first learn
the specific coordination required to propel the spinning rotor. The
learning effort is well worth it however, because you will have developed
valuable strength and coordination which can promote significant
improvement in many sports and aid in the rehabilitation of many injuries
and arthritic conditions. Please follow the starting instructions
carefully and patiently.
Method A:
Hold Original Gyro Exerciser in your right hand (or left
hand if you are left handed), with the rotor (open portion of the case)
facing up, or at a 90 degree angle to your body. With the opposite hand
stroke the rotor firmly once or twice in the direction of the rotor lines.
Method B:
Hold Original Gyro Exerciser in your right hand, strike rotor with
your left thumb. Flip the thumb forward, striking the rotor in the same
direction as the lines on the rotor. Repeat two or three times until the
rotor starts to spin.
Method C:
Lay out an 18" strip of ordinary cloth adhesive tape 1 1/2" to
2" wide on a hard surface (desk top or table.) Push the Original Gyro Exerciser rotor quickly along the strip. Your Gyro should now be
spinning fast enough to start the hand motion needed to acquire operating
speed.
Original Gyro Exerciser Operating Instructions
- It is important to achieve a minimum
RPM prior to attempting to operate your Gyro. You must learn your own
basic starting rotor speed. For most people the faster they can spin
the rotor the easier it becomes to begin the exercise phase of
operating the Gyro.
- With the rotor now spinning, turn it over with
the rotor facing down.
- Bend your wrist down slightly and hold elbow
still. For learning we recommend only wrist activity first.
- Begin turning your wrist in a circular motion
as though you were stirring the inside of a small bowl, or rolling
around a marble at the bottom of a jar.
- Make the turns smooth and slow for the first
few turns, then gradually increase the speed. As your actions increase
you should become aware of the increased rotor speed and the resulting
opposing forces which serve to work the muscle groups in your wrist
and forearms.
Principles
of Gyroscopes
Gyroscope - {jy-roh-skohp}
A
gyroscope is a solid object that is designed to spin around a central
axis. The word gyroscope derives from the Greek words that mean "to
view a rotating body," such as the Earth. A spinning toy top provides
a simple example of a gyroscope. In a toy gyro top, the heavy, rimmed
rotor is fixed to an axle. The ends of the axle rest on bearings in a
steel ring, or gimbal. Start the top spinning and as long as it continues
to spin rapidly, the top will remain balanced on its pointed end. More
important, the direction of the top's spin axis will resist any attempt to
change the direction of the axis about which the rotor turns. This basic
property results from the top's strong Angular Momentum. This resistance
of the gyroscope's spin axis to change in direction is known as gyroscopic
inertia and is what provides the exercise benefit found in the
Gyroscopic Exerciser.
The rigidity in space of a gyroscope is a consequence of
Newton's first law of motion which states that a body at rest tends to
continue in its state of rest or uniform motion unless subject to outside
forces. Thus, the wheel of a gyroscope, when started spinning, tends to
continue to rotate in the same plane about the same axis in space...
Precession
When a force applied to a gyroscope tends to change the
direction of the axis of rotation, the axis will move in a direction a
right angles to the direction in which the force is applied. This motion
is the result of the force produced by the Angular Momentum of the
rotating body and the applied force as a can be observed through the
transparent body of the Original
Gyro Exerciser
"Super Gyro".
The Law Of Conservation Of Energy
The law of conservation of energy is now one of the most
important and firmly established conservation laws of nature, although it
has been necessary to recognize that energy may occur in many different
forms and is also equivalent to mass. Perhaps the simplest form of energy
arises from motion, where the Kinetic Energy of a particle of mass m,
moving with speed v, is defined as (1/2)mvv. The total kinetic energy of a
system of particles is the sum of the kinetic energies of the individual
particles. When work is done on a particle, the total work done on all the
particles is equal to the increase in kinetic energy of the whole system.
If the net work is zero, kinetic energy is conserved. This network must
include work done by internal forces of the particles acting on each
other. This is why when a skater spinning with arms outstretched pulls
them in, he or she spins faster (with increased kinetic energy) because of
work done on the body. In this example, angular momentum is conserved
because there are no external torques.
Scientific
Analysis
Motion of the Hand:
Original
Gyro Exerciser is
held by a prehensile power grip. The object is clamped by the partly
flexed fingers from co-contraction of the profundus and superficialis
flexor muscles, and extensor digitorum. Also stabilizing demands are
placed on both the volar and dorsal interossei and on the lumbricales. It
is held in the palm by counter pressure applied with the thumb in
opposition. This is accomplished by contraction of the adductor pollicis,
and flexor pollicis longus and brevis. In addition, static contraction of
the opponens pollicis and opponens digiti minimi occurs. During the work
phase of the activity, these muscles are exercised in an isometric manner,
the length of the muscles is maintained, while the tension within the
muscle is increased and/or decreased as the demands of the gyroscopic
force change. Grip strength studies show that the limiting factor appears
to be the ability of the thumb to oppose the force of the fingers .Original
Gyro Exerciser is
able to successfully exercise these muscles, and their related synergistic
groups.
Motion of the Forearm:
Rotation of the forearm also assists in maintaining the
speed of the Original
Gyro Exerciser. The
pronator and supinator groups act as antagonist, stabilizer and antagonist
in a similar fashion as the muscles of the wrist. The biceps brachii
assists with supination, and the brachioradialis assists in pronation to
midpoint when the elbow is flexed to 90 degrees. The action of the forearm
is performed in mid-position to pronation, and the radius is rotated
across the ulna, or in mid-position to supination where the bones lie
parallel to each other.
Motion of the Wrist:
To maintain or increase the speed or rotation of Original
Gyro Exerciser, the
motions in the wrist rotate in the opposite direction. Each of the muscles
of the wrist functions as an antagonist, a stabilizer, and an antagonist
as the load shifts. The degree of motion of the wrist is inversely
proportional to the speed of thrust of Original
Gyro Exerciser. At
high speeds, the wrist is exercised within a range parameter that allows
the greatest strength of prehensile position for the hand; the wrist is in
mid-position and rotating within 10-15 degrees of flexion, and extension.
Motion of the Arm, Shoulder, and Shoulder Girdle:
The muscular action of the arm, shoulder and shoulder
girdle is primarily of stabilization for the activity of the forearm,
wrist and hand. The specific demands on the muscle groups in these joints
are variable according to the position of the extremity. For example, Original
Gyro Exerciser is
held in the hand pronated, the elbow is extended, the shoulder is abducted
and internally rotated, and the shoulder girdle is upwardly rotated and
abducted. All musculature of these joints are co-contracting for
stabilization. However, greater strength demands are placed on the elbow
extensors, the shoulder abductors and external rotators, and the shoulder
girdle abductors and the rotator cuff muscle groups. The demands are
extremely variable, and can be changed to obtain specific results by
positioning the extremity.
