Acute Effects of Low and High-Speed Resistance Training on Blood Pressure in Older Adults: A Crossover Study

Not Applicable

Completed

• Conditions: Blood Pressure; Frailty
• Interventions: Other: Exercise

• Registration Number: NCT05310006
• Lead Sponsor: University of Campinas, Brazil

Brief Summary

The first study was a randomized crossover trial that compared the acute effects of High Speed Resistance Exercise (HSRE) and Traditional Resistance Exercise (TRE) on blood pressure parameters in a sample of frail older adults. Participants performed three experimental sessions (i.e., HSRE, TRE, and a control session \[CS\]) in a random order and separated from one another by seven days (standard deviation \[±\] 1 day). Food consumption was maintained constant during 48 h prior to the exercise session and a standard breakfast was offered 60-90 min before the beginning of the experimental sessions. The pharmacological therapy was kept constant during the whole study, and participants took their anti-hypertensive medication at the same time in all experimental days as prescribed by their physician.

Arm && Interventions

Group	Intervention	Description
Traditional Resistance Exercise (TRE)	Exercise	Exercise sessions were performed using four sets of 8-10 repetitions at 70-75% of the maximal strength. The concentric and eccentric phases were carried out for 2 s.
High Speed Resistance Exercise (HSRE)	Exercise	Exercise sessions performed using eight times (sets) with 4-5 repetitions at 70-75% of the maximal strength. The concentric phase was performed as fast as possible, and the eccentric phase was carried out for 2 s.
