Hytro

The science is settled. We made it wearable.

Blood Flow Restriction is one of the most researched interventions in performance sport. Hytro translates that evidence base into practical, wearable application - so practitioners can connect the science to real moments in the season.

What BFR does - and why teams use it.

Blood Flow Restriction works by tightening a strap at the top of the limb to lock blood in the muscles during light exercise or recovery routines - helping muscles get stronger and recover faster than they would without it.

Once a rehabilitation tool, BFR is now applied across the performance spectrum. "Performance BFR" spans heightened exercise preparedness, improved training adaptations, effective pain modulation and expedited recovery.

Hytro builds that mechanism into the product: consistent occlusion pressure, adjustable to individual fit, with no wires, batteries, pumps or consoles.

Before. During. After.

Depending on when you apply BFR, you change what it does. Three applications, one product.

Before exercise

Preparation BFR

Drives fresh blood into the tissues, helping joints move better and warming muscles more effectively than stretching alone - lowering injury risk and easing tendon pain and soreness, with joint pain reduced by up to 38%.

During exercise

BFR Training

Low-load exercise under restriction increases muscle-fibre recruitment and drives adaptations similar to heavy loading - building strength and size with light weights, in-season, without the usual recovery cost.

After exercise

Recovery BFR

Increases recovery-hormone production and creates a flushing effect that clears lactic acid and waste from the muscles - reducing soreness by 47%, joint pain by 38% and fatigue by 39%. Active or passive, anywhere.

The claims. The evidence.

The performance outcomes practitioners ask about most - and how the research supports each one.

Validated. Measured. Safe at squad scale.

Hytro is the only BFR product validated as safe to use without supervision (Neal et al., 2023) - which is what makes squad-wide, unsupervised deployment possible.

Partial occlusion

Hytro restricts venous return while arterial inflow continues - never full occlusion - making it safe to use with large groups and away from club facilities.

Two settings

A simple two-setting system built into the product delivers consistent pressure every time - no calibration, no consoles, no guesswork.

Peer-reviewed

Proven safe and effective by academic research (Dhokia et al., 2022; Neal et al., 2023) - with an active research programme across elite sport.

What practitioners say.

Hytro offers a way of stressing the system, you're doing it with a little bit more intelligence. The athletes get quality training and are able to recover quickly.

When applied properly, BFR is an effective way to achieve hypertrophy throughout rehabilitation, especially with load-compromised players. When they're unable to load the injured limb, BFR allows them to still make gains.

If we finish a game at 4am, we know recovery, refuelling and sleeping is a priority. Instead of staying at a facility to recover, Hytro can be put on straight away - even in an interview straight after a match.
