Mechanical / Biomechanical (vibration)

Mechanical, not energetic. This family delivers vibration — real mechanical acceleration — to muscle and bone, and it is the atlas's eighth mechanism family. Two strands sit here: the Soviet biomechanical-stimulation method (Nazarov's longitudinal muscle-fibre vibration, ~18–33 Hz) and Western whole-body-vibration platforms. Both have a coherent neuromuscular / bone-loading rationale and genuine controlled data — but the evidence is mixed and low-certainty, so both sit under study rather than evidence-supported. The discipline is the same as everywhere else in the atlas: a real, dosed physical lever, graded by what the trials actually show.

Nazarov BMS + Krainov Belt — Biomechanical VibrationLongitudinal mechanical vibration applied along muscle fibres (~18–33 Hz) for strength, flexibility, and recovery — tested on athletes and cosmonauts. A real mechanical modality with a coherent neuromuscular rationale; the evidence is early, sparse, and largely Soviet-era, with no modern large RCTs. The RU/Eastern mechanical strand.Insufficient evidence / under study grade C Whole-Body Vibration (WBV) TrainingA vibration platform delivers vertical mechanical accelerations through the feet to muscle and bone, aimed at bone mineral density, muscle strength, balance, and falls. Multiple RCTs and meta-analyses show site-specific BMD gains, but GRADE certainty is low and there is no regulatory treatment clearance for osteoporosis — a real mechanism with mixed, low-certainty evidence.Insufficient evidence / under study grade B/C
