My journey with EMS began when I recognized its potential to overcome many of the obstacles that come with consistent exercise. There are tons of fitness options out there, but the more conditions, injuries, and limitations you face, the fewer choices seem available.

EMS can help people of all fitness levels, from elite athletes to complete beginners, as well as seniors and young professionals. However, I believe EMS truly shines by providing low-impact, high-intensity workouts in a very short time, which can be incredibly beneficial for older populations with limited mobility.

Now, let's get a little nerdy and explore how EMS actually works. We'll start with a basic understanding of how our own muscles function.

Understanding Muscle Contraction

Muscle contraction is a complex process orchestrated by the nervous system.

The process of muscle contraction begins with intricate electrical signals. Nerve cells transmit electrical signals to neuromuscular junctions, which then trigger the release of acetylcholine. This neurotransmitter binds to receptors on muscle fibers, initiating a chain reaction that culminates in the release of calcium ions. Calcium ions play a crucial role in enabling the interaction between actin and myosin filaments, the proteins responsible for muscle contraction.

• Neural Signals: An electrical signal, called an action potential, travels along a motor neuron.
• Motor Units: A motor neuron and all the muscle fibers it innervates form a motor unit.
• The "All-or-None" Principle: Muscle fibers within a motor unit either contract fully or not at all.
• Force Generation: The number of activated motor units determines the force generated. More motor units = more force.
• Henneman's Size Principle: During voluntary contractions, the nervous system typically recruits smaller motor units (slow-twitch) first, followed by larger ones (fast-twitch) as more force is needed.

Muscle Fiber Types:

As mentioned, Henneman's size principle dictates that smaller muscle fibers contract first. This explains why, for example, we don't throw our phones across the ceiling every time we pick them up. We only activate the minimum number of muscle fibers needed.

• Slow-twitch (Type 1): These endurance-focused fibers are rich in mitochondria and myoglobin, allowing them to sustain smaller movements and postural control. They are ideal for activities like long-distance running and high-repetition exercises.
• Fast-twitch (Type 2a - Intermediate): These fibers exhibit a blend of characteristics, offering a balance of speed and endurance. They are well-suited for activities like mid-distance running and moderate-repetition exercises.
• Fast-twitch (Type 2x/2b - Fast Glycolytic): These powerful fibers excel at strong and explosive movements but fatigue quickly. They are crucial for activities like sprinting, and low-repetition, high-weight exercises.

Electrical Muscle Stimulation (EMS)

EMS technology delivers electrical impulses to the muscles, mimicking the natural signals from the nervous system. This stimulation can:

• Recruit More Muscle Fibers: Potentially activate a higher percentage of muscle fibers, including those fast-twitch fibers typically requiring more experience to engage through traditional training.
• Accelerate Strength Gains: By directly targeting fast-twitch fibers, EMS can facilitate faster strength gains compared to solely relying on weight training.

Two primary theories explain how EMS activates muscle fibers:

• Shotgun Theory: Suggests that EMS indiscriminately stimulates all muscle fibers beneath the electrode, regardless of fiber type. This is also the most likely theory.
• Reverse Size Principle: Proposes that EMS preferentially activates fast-twitch fibers (Type 2b) first, followed by intermediate (Type 2a) and then slow-twitch (Type 1) fibers.

The Science of Whole-Body Electrical Muscle Stimulation

WB-EMS utilizes a specialized suit equipped with electrodes that deliver electrical impulses to major muscle groups.

Mimicking Natural Pathways: I always have my clients "pre-contract" the target muscle before the electrical stimulation, allowing for more natural and efficient muscle activation.

Benefits of WB-EMS:

• Quick Strength Gains: Targets fast-twitch fibers from the outset, accelerating strength development.
• Time-Efficient: Short session durations make it ideal for busy individuals.
• Low-Impact: Minimizes stress on joints, suitable for those with joint pain or recovering from injuries.
• Personalized Training: Allows for precise adjustments of intensity and duration to individual needs and fitness levels.

How does it compare to traditional training?

I was a traditional personal trainer for over a decade before I became an EMS trainer. I trained mostly women, seniors, diabetes patients, and people with injuries. I saw great results across my clientele, but never as fast as with EMS.

The reason is that when training someone new to lifting, we have to start with low weights and high repetitions to work on form, technique, body awareness, and muscle endurance. It usually takes eight to twelve weeks before getting into real strength training with higher weights and lower repetitions.

We can completely circumvent this problem with EMS, as those strength muscle fibers can get engaged from the very first session. Form and technique, although always important, don't pose as much of a risk since we will mostly use bodyweight or some light dumbbells and resistance bands. You will also get body awareness since there's no way of escaping the stimulation.
