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

Abstract

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.
