The Claim
Is hydraulic resistance HIIT perceived as harder than other workouts?
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People feel like they’re working much harder during a 30-minute hydraulic machine HIIT workout than during weightlifting, running, or biking, even though they’re resting part of the time.
See the scientific wording
The rating of perceived exertion (RPE) during a 30-minute hydraulic resistance system (HRS) high-intensity interval training session in healthy men averages 16 ± 2 on the Borg 6–20 scale, which is significantly higher than during resistance training (13 ± 2), treadmill endurance (10 ± 2), or cycling endurance (11 ± 1).
What the research says
1 studyThe study had men do a 30-minute intense workout using a hydraulic machine and found they felt it was much harder (RPE of 16) than lifting weights, running on a treadmill, or cycling — exactly what the claim says.
