Accommodating resistance equipment

• Positional data revealed that the backs performed a greater number of sprints (20 km•h-1) than the forwards (34 vs. Conversely, the forwards entered the lower speed zone (6-12 km•h-1) on a greater number of occasions than the backs (315 vs.

229) but spent less time standing and walking (66.5 vs.

The final functional characteristic of the Myo Truk resistance machine is strong activation of the gastrocnemius and soleus muscles of the calf during significant dorsiflexion and plantar flexion of the ankle joint.(25) Demonstrating full extension on the Myo Quip Myo Truk - hip and knee joint angles change at same rate.

No adverse consequences from attempting to use excessive weight - athlete cannot be trapped under heavy load unlike barbell squat or 45 leg press (25) The explosion during an Olympic lifting exercise is executed by the simultaneous action of the muscles of the legs and torso…

The Myo Truk facilitates triple extension development both through traditional strength training paradigms and also dynamically without the same impacts on time limitations of the athlete and coach, the central nervous system and the musculosketal system.

The hip and knee joint starting angles are able to be adjusted to below 90° if a greater range of movement is desired, but as discussed the integral component of the machine is the ability of the back and spine to maintain normal curvature. Heavy resistance training results in increases in the contractile rate of force development (RFD), impulse and efferent neuromuscular drive of human skeletal muscle allowing for subsequent transformation into enhanced sports specific speed and power characteristics.(1) A distinguishing characteristic of the Myo Truk in terms of strength training lies in its ability to be eccentrically controlled so efficiently throughout range whilst the athlete maintains normal lumbar curvature. This has further positive implications for the ability of the Myo Truk to generate strength and power development. An effective resistance training program should be run in conjunction with dynamic sport specific training. The ability to be able to produce force throughout time (impulse), possess dynamic strength capacities at contact situations and utilise a vast array of different speed attributes are all critical features within the game of rugby union.
