Muscle Growth Physiology and the Role of Modern Technologies Tesla Former and Emsculpt Neo
How Our Muscles Work
Red (slow-twitch, type I):
  • Rich in mitochondria and myoglobin
  • Use oxygen (aerobic mode)
  • Endurance-oriented, moderate strength
  • Use fatty acids and glycogen for energy
White (fast-twitch, type II):
  • Contract quickly and generate maximum power
  • Work in anaerobic mode (without oxygen)
  • Main energy source — glycogen and creatine phosphate
  • Fatigue faster, but they are responsible for muscle growth
Muscles consist of millions of thin fibers. These fibers are of two types:
Both types are essential: red fibers provide endurance and density, white fibers give strength and volume.
The process of muscle growth is called hypertrophy and goes through several stages:
How Muscle “Pumping” Works
Load & Micro-damage
strength training or stimulation creates micro-tears.
Satellite Cell Activation
reserve cells fuse with muscle fibers, adding nuclei.
Protein Synthesis Boost
muscles repair, grow thicker and stronger.
Adaptation
fibers become more resistant, muscles increase in strength and size.
In the gym, fibers activate progressively (red first, then white) depending on load, speed, and time. Activating all fibers at once naturally is impossible.
Training with Maximum Weight
Tesla Former FMS
— Training with Maximum Weight
FMS (Functional Magnetic Stimulation)
  • Unlike gym workouts, it activates all fiber types at once.
  • White fibers get strong growth stimulus.
  • Red fibers improve endurance and metabolism.
  • Result: muscles become denser, stronger, and bigger — especially glutes, abs, back, and pelvic muscles.
Emsculpt Neo — Muscles + Fat Burning
Emsculpt Neo combines two methods:
1
During the session:
  • White fibers "pump" → size & strength grow.
  • Red fibers work in “cardio mode” → more fat used as energy.
  • RF destroys fat cells → naturally eliminated by the body.
Result: fat melts, muscles grow, body becomes toned and sculpted.
HIFEM (High-Intensity Focused Electromagnetic Field) — stimulates all fibers (like Tesla, but deeper and stronger).
2
RF (Radiofrequency) — heats tissues to 42–44°C, triggering fat cell apoptosis.
Comparison
Tesla Former FMS= “Gym with Maximum Weight” → Pure muscle stimulation, growth of strength & volume.
Emsculpt Neo (HIFEM + RF) = “Gym + Cardio + Fat Burning at Once” → Muscle growth + fat loss + body contouring.
Why Does It Work Better than the Gym?
In the gym: muscles contract a few dozen times per set.
With Tesla & Neo: tens of thousands of supramaximal contractions per session.
This intensity is impossible naturally.
FMS and HIFEM+RF are not a replacement for training, but an accelerator of results — stronger, leaner body in less time.
