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.

Study Arms (3)

High Speed Resistance Exercise (HSRE)

EXPERIMENTAL

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.

Other: Exercise

Traditional Resistance Exercise (TRE)

EXPERIMENTAL

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.

Other: Exercise

Control Session (CS)

NO INTERVENTION

Participants remained seated in a comfortable chair listening to music and/or talking with study investigators for approximately 30 min.

Interventions

Exercise OTHER

Exercise sessions were performed in the morning (07:00 am-12:00 am) under the supervision of at least two fitness instructors in the rehabilitation unit of the nursing home.HSRE and TRE were designed according to the peculiarities of each type of resistance exercise (Chodzko-Zajko et al., 2009). During TRE, participants performed four sets of 8-10 repetitions at 70-75% of the maximal strength. The concentric and eccentric phases were carried out for 2 s. For HSRE, exercises were performed 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. Bilateral calf raise was performed using the same load as unilateral knee extension.
