High-intensity body weight interval training modifies neurochemistry in AD disease: Preliminary data from a randomized control trial

Background

Alzheimer's disease (AD) is an incurable condition characterized by cognitive and neurochemical impairments, necessitating the exploration of alternative interventions. Physical exercise shows promise, but the effects of high-intensity protocols on the neurochemical aspects of AD-related neurodegeneration remain poorly explored.

Objective

This study examines the effects of high-intensity body weight interval training (PMED) on brain-derived neurotrophic factor (BDNF) and phosphorylated-TAU protein (p-TAU) in AD disease.

Methods

Thirty-four elderly individuals diagnosed with AD disease were divided into two groups of 17 subjects: GCP, which participated in PMED (30 min at 80–90 % of maximal cardiac frequency three times per week), and GCS, which had no interventions. Pre- and post-measurements of BDNF and p-TAU were conducted.

Results

The GCS group showed no changes in his neurochemical factors (p > 0.05). In contrast, the GCP group experienced increased BDNF levels and decreased p-TAU blood concentrations (p < 0.0001 for both).

Conclusions

PMED increased BDNF and reduced p-TAU concentrations, improving neurochemistry in AD disease. This can open an avenue of new interventions using high-intensity body weight interval training, including, in home base programs, which can be an advantage to engagement.
