Strength in Numbers #207
When it comes to keeping throwing athletes on the field, recovery is more critical than the training. Every day, elite pitchers, position players, swimmers, and tennis athletes are pushing their bodies harder than ever, and injuries are climbing.
But what if I told you there’s a non-invasive, science-backed technology that could significantly improve tissue recovery, accelerate healing, and reduce pain — without lifting a finger?
I was inspired to write this article while working with an elite baseball player who had a fracture. As part of the recovery process, we sought non-invasive bone healing therapies to expedite bone mineralization and unionization, promoting significant healing in a shorter timeframe.
This isn’t science fiction. I am covering Pulsed Electromagnetic Field Therapy (PEMF) in this Strength in Numbers — and it’s one of the most overlooked tools in recovery science.
Read on to learn more about this effective, painless, and unique way of treating pain, injuries, and promoting recovery.
What Is PEMF Therapy?
PEMF therapy delivers low-frequency electromagnetic pulses to the body’s tissues. These fields pass harmlessly through the body and stimulate cellular activity at the mitochondrial level, resulting in improved circulation, enhanced oxygenation, and accelerated tissue regeneration. Think of it like charging your cells — but instead of caffeine, you’re using energy waves.
Initially approved by the FDA in 1979 for treating non-union bone fractures, PEMF has evolved into a versatile therapeutic tool for managing musculoskeletal injuries, pain relief, and enhancing performance recovery.
Some forms of PEMF utilize manual form modalities, meaning that electrical current travels through the clinician’s body to provide manual treatment for athletes.
In this video, the patient is undergoing manual active tissue release therapy using PEMF to contract and release muscles. This also helps promote improved nerve conductance that enhances the quality of muscle contraction in the treated muscle groups.
How Overhead Athletes Benefit?
Overhead athletes (such as baseball, softball, tennis, and swimming) rely on peak tissue health to perform optimally. The repetitive nature of their movements creates microtrauma in soft tissue, joint inflammation, and neural tension. PEMF helps reverse those effects by:
- Reducing throwing arm inflammation
- Stimulating collagen production and tissue regeneration
- Improving tendon health and circulation in stressed areas
- Supporting the throwing arm nerve function and reducing irritation
- Enhancing recovery between high-effort throwing sessions
Athletes using PEMF as part of their recovery see improved arm freshness, sleep quality, and durability — all key factors in sustaining high-velocity performance throughout a season.
In this video, a sophisticated PEMF technology is shown. As you can see, this is a non-invasive procedure. However, if you are interested in this form of treatment, do your research to ensure the PEMF waves are high enough and the frequencies are strong enough to heal tissue, as other, less expensive products may not be effective enough.
What Does This Do for Pitchers on a Cellular Level?
A powerful and consistent throwing delivery depends on:
- Efficient ion pumps (Na⁺/K⁺) to keep nerve signals sharp
- Plentiful ATP for explosive movement
- Healthy mitochondria for sustained energy
- Low oxidative stress to keep tissues resilient
Getting deeper into PEMF therapy and what the interactions are for cellular function include the following:
Na⁺/K⁺ Pump – The Cell’s Reset Button
- Every muscle contraction starts with an electrical signal. To keep those signals firing correctly, cells rely on the sodium-potassium pump (Na⁺/K⁺ pump). This pump moves sodium (Na⁺) out of the cell and potassium (K⁺) into the cell. By doing this, it maintains the electrical balance that muscles and nerves require to function properly.
- When you’re throwing repeatedly, your cells fire off thousands of signals, and this pump keeps your muscles ready for the next pitch.
The sodium and potassium channels are densely populated in the gaps along the axon of the nerves. We require these channels for the rapid transmission of nerve impulses that facilitate muscle contraction. If the sodium-potassium exchange is less than optimal along the nerve nodes, muscle force, contractile velocity, and muscle power will degrade.
ATP – The Energy Currency
- ATP (adenosine triphosphate) is the energy that powers everything inside your cells, including the Na⁺/K⁺ pump. Without ATP, muscles can’t contract or recover. You burn a lot of ATP during high-intensity activities like pitching, which is why energy systems need to be efficient; recovery is therefore crucial.
ATP is the energy molecule that creates action. We need it for muscle contraction and for propagating nerve signals to muscles to coordinate contraction. Otherwise known as metabolic energy, if ATP stores are low, the sodium-potassium pump does not work effectively. Therefore, our strength and coordination in the throwing delivery can greatly suffer.
Mitochondria – The Power Plants
- Mitochondria are the “power plants” of your cells. They produce ATP using oxygen and nutrients. The better your mitochondria work, the more energy your body can generate for powerful, repeatable pitching mechanics.
- Training, nutrition, and recovery all impact mitochondrial function—when you’re exhausted, your energy production suffers.
Mitochondria are found in all cells. They are the factors for ATP. If we have low nutrients and do not eat properly, we can lower our ATP production – our energy source for throwing with maximal force, velocity, and motor control. This is a microcosm that causes significant problems when the athlete is ineffective at storing, generating, and recovering ATP sources.
Oxidative Stress – The Cellular Wear and Tear
- When mitochondria make energy, they also produce byproducts called free radicals. These can cause oxidative stress, which damages cells if not properly cleared out. In pitchers, repetitive high-velocity throwing increases oxidative stress, especially in the shoulder and elbow.
- If oxidative stress accumulates without sufficient rest or recovery, it can lead to fatigue, inflammation, and ultimately, injury.
- Training smart and recovering well helps keep these systems in balance, maximizing your performance while reducing your risk of injury.
Heavy amounts of muscle contraction, as well as muscle cell damage, release free radicals. These molecules can cause damage to the cell’s membranes and can attack healthy tissue. When we are sore for an extended period after pitching, some of the soreness and inflammation come from chemical damage caused by free radicals, not just microtears in the tissue.
This video clip is from our ‘Eliminating Arm Pain and Soreness’ Course, where we discuss nutrition, food sources, and portions to reduce inflammation. In combination with therapeutic tools like PEMF, a balanced intake of complex carbohydrates for ATP production, protein sources to facilitate greater blood circulation, and micronutrients to help neutralize free radicals through antioxidants can reduce pain, shorten recovery windows, and promote performance.
What the Research Shows on PEMF
The science is catching up — and it’s encouraging.
- A study in the Journal of Shoulder and Elbow Surgery highlighted the ability of PEMF to enhance tendon healing and reduce inflammatory cytokines, key factors in preventing chronic overuse injuries in overhead athletes.
- An animal model study published in the Journal of Orthopaedic Research showed that PEMF therapy accelerated tendon healing and reduced scar tissue formation, which is critical for post-injury recovery of the rotator cuff and UCL.
- In tennis, a PEMF study was applied in treating lateral epicondylitis (tennis elbow) with positive effects.
How It Works with ArmCare.com Integration
We believe data and technology drive better decisions.
Some clinics are now integrating PEMF into post-Tommy John protocols, reporting improved elbow range of motion, lower pain levels, and faster progression to throwing. I will continue to research the impact of arm strength on PEMF as we work with our athletes.
In my opinion, if you cannot raise your ArmScore, adding PEMF provides a recovery advantage and may enhance strength based on the cellular processes mentioned above. Our platform helps you identify fatigue, asymmetry, and functional decline. PEMF can then become your tool to repair faster and delay breakdown before it begins. You can scale the effectiveness of treatment by adjusting the intensity or frequency of your treatment.
Some suggestions I have for use cases are the following:
- Post-game recovery for pitchers
- Supporting tissue regeneration during deload phases
- Complementing strength training without added physical stress
- Accelerating rehab post-injury or surgery
A crucial step is to consult a physical therapist or doctor to gain more insight into this technology and find a reputable location for administering this treatment method.
Summing it Up
PEMF therapy isn’t a magic bullet. However, when combined with smart training, testing your throwing arm, individualizing your workload, and recovery planning, it’s a tool that can help reset your throwing arm. As workload demands increase, recovery needs to evolve, and recovery approaches are more important than training, as you cannot build if you continually destroy your muscle cell tissue, function, and responsiveness.
Before spending considerable money on recovery approaches, you can learn what to do for yourself with our Eliminating Arm Pain and MLB Recovery Habits Courses. Before adding recovery technologies, improve your methods with everything around you. With the foundation of recovery established, all integrated technologies to promote recovery will be enhanced.
But remember – Strength Matters Most, and stronger arms are harder to kill.
