The invention muscle fiber excitation system (MFES) targets improving muscular and skeletal systems and preventing blood clots. MFES consists of 2 shafts, each affixed with 2 CAMs featuring surround peaks and valleys surfaces, a platform with stiffener side and compliant other side, and 4 plungers at the corners. The shafts tied with timing bets through pulleys are driven with DC motor. As the CAMs rotate the peaks and valleys make contacts with the platform stiffener side causing the platform to telescope 1 mm to 4 mm displacements, transferring contact stress stimuli from platform stiffener to compliant human contact side at frequency that encompass muscle fiber excitation frequencies. Wearable and standing model tests show improved bone density, muscle contraction and blood flow, preventing blood pooling. There is no side effect compared to use of blood thinners for blood clot prevention. Wearable model is concealable compared to compression pneumatic device with user complaints.
