What if your warm-up is longer than it needs to be?
And what if science just proved there’s a faster way?
A brand-new 2025 clinical trial from Japan has shaken up traditional stretching advice.
Researchers tested whether neuromuscular electrical stimulation (NMES) combined with elastic taping could improve ankle flexibility as effectively as static stretching.
The result?
One minute of NMES plus taping worked just as well as five minutes of static stretching.
And it did it safely.
First — What Is NMES?
Neuromuscular Electrical Stimulation (NMES) is a method that sends small electrical pulses into muscles.
These pulses cause controlled muscle contractions.
NMES is commonly used for:
-
Muscle activation
-
Rehabilitation
-
Strength support
-
Circulation improvement
-
Flexibility support
Unlike passive stretching, NMES actively contracts the muscle.
That contraction may help:
-
Improve tissue glide
-
Reduce stiffness
-
Enhance joint range of motion
-
Support warm-up efficiency
What Did This Study Actually Test?
Researchers from the International University of Health and Welfare (Japan) conducted a randomized crossover clinical trial on 83 healthy university students.
They compared:
1️⃣ Combined Intervention (CI)
• 1 minute of NMES applied to calf muscles
• Elastic tape applied to the sole of the foot
versus
2️⃣ Static Stretching (SS)
• 5 minutes of traditional calf stretching
They measured:
-
Ankle dorsiflexion angle (primary outcome)
-
Finger-floor distance
-
Straight leg raise
-
Plantar flexor strength
-
Knee flexor strength
The Results
Both methods improved ankle flexibility.
But here’s the key finding:
The 1-minute NMES + taping intervention was statistically equivalent to 5 minutes of static stretching.
Even better?
There was no loss of muscle strength in either group.
That matters.
Because prolonged static stretching before activity has been shown in other research to temporarily reduce muscle strength.
This shorter NMES-based method may provide flexibility support without that drawback.
Why This Matters
Time efficiency matters in:
-
Sports warm-ups
-
Rehabilitation clinics
-
Busy schedules
-
Pre-competition routines
If flexibility gains can be achieved in 1 minute instead of 5, that changes practical application.
For EMS users, this reinforces something important:
EMS isn’t just for muscle strength.
It may support:
-
Mobility
-
Flexibility
-
Muscle activation
-
Warm-up preparation
