The MyoTruk
has now been released as one of MyoQuip's Myo
range of strength equipment which embodies direct-linkage force
transmission. It replaces the
ScrumTruk in our product range.
Since its introduction in 2004 the ScrumTruk has been routinely used
for enhancing the basic strength, muscle mass and explosiveness of
rugby players, both back and forwards, from schoolboy to international
level. But, in addition, it has replaced or complemented the barbell
squat in the weights programs of world standard rowers, national
representative basketballers, and elite athletes in other sports. This
multi-functionality has been further enhanced with the release of the
MyoTruk.
The two most important distinguishing
features of the MyoTruk
are the horizontal pushing position of the athlete and the use of
MyoQuip's patented technology, ensuring constantly increasing
resistance
throughout the exercise movement.
The MyoTruk
has proven to be a very effective alternative or complement to the
barbell squat in building strength in the gluteal and quadriceps muscle
groups.
The photo below shows the correct
starting position for operating the
MyoTruk. Note that hip and knee joint starting angles below 90° can be
used if a greater range of movement is desired.
Unique features and
performance characteristics of the MyoTruk:
Gravitational effect on
the horizontal trunk causes moderate curvature of the lower spine
similar to its alignment when standing erect.
Comfortable and natural body position
throughout the full range of movement ensuring no adverse loading on
spine, hips or knees.
Horizontal trunk position triggers
isometric contraction of the stabilising muscles of the pelvic and
abdominal regions.
Intuitive operation - athletes do not
need to be supervised or spend considerable time mastering a
complicated movement.
Exercise can be performed without
discomfort even by athletes who cannot squat because of back problems.
Provides full-range effective
activation of leg extensors from start to lock-out.
Synchronicity of hip and knee joint
angles ensures appropriate distribution of effort between gluteus
maximus and quadriceps muscles.
Strongly activates the gastrocnemius
and soleus muscles of the calf.
Involves significant dorsiflexion and
plantarflexion of the ankle joint.
No adverse consequences from
attempting to use excessive weight - athlete cannot be trapped under
heavy load unlike barbell squat or 45° leg press
No need for spotters when attempting
near-limit efforts.
"ScrumTruk provides a specificity of
training off the field that enhances performance on it. ... Having
utilised ScrumTruk in my training programmes for the last 3 years, I
thoroughly recommend its value."
Bob Egerton
Wallaby; Head Coach, Sydney Grammar School First XV
"Gluteal strength and
forceful hip movement are essential factors in developing boat speed
for rowing. The ScrumTruk facilitates power gains, in these areas, in a
controlled environment. I would recommend the ScrumTruk to anyone
wishing to develop superior power."
Marty Rabjohns
Director of Rowing, The University of Sydney; Cox, Australian Senior
