Key result
High intensity exercise performed 15% above maximal lactate steady state significantly increased aerobic fitness by 28.1% and reduced systolic blood pressure in spontaneously hypertensive rats.
Why the study?
Does treadmill exercise training at different intensities relative to MLSS reduce systolic blood pressure and improve aerobic fitness in spontaneously hypertensive rats?
Does treadmill exercise training at different intensities relative to MLSS reduce systolic blood pressure and improve aerobic fitness in spontaneously hypertensive rats?
Effect estimate: 28.1% increase
Absolute Event Rate: 33.3% vs 25.5%
p-value: p=0.01
In spontaneously hypertensive rats, both low and high-intensity exercise reduced systolic blood pressure, but only high-intensity exercise improved aerobic fitness.

Supports intensity-specific exercise effects in hypertensive rat models; leaves open translation to human hypertension management.
Petriz et al. (2015) studied Hypertension (n=17). Treadmill running exercise vs. Non-exercised control was evaluated on Aerobic fitness (Vmax) (28.1% increase, p=0.01). High intensity exercise performed 15% above maximal lactate steady state significantly increased aerobic fitness by 28.1% and reduced systolic blood pressure in spontaneously hypertensive rats.
