Abstract
OBJECTIVE/ BACKGROUND: The objective was to analyze the acute effects of a single bout of arm cranking exercise on affective and cardiovascular parameters in patients with symptomatic peripheral artery disease (PAD). METHODS: This was a prospective, controlled, crossover study. Eleven men with symptomatic PAD underwent two experimental sessions in a random order: control or arm crank exercise (15 × 2 minutes bouts of arm crank exercise interrupted by 2 minutes rest intervals). During exercise, ratings of perceived exertion (Borg scale) and affective responses (pleasure/displeasure) were obtained at the first, fifth, tenth, and fifteenth bouts. Before and after the experimental sessions, cardiovascular parameters (blood pressure and heart rate) were obtained. Data were analysed by a two-way repeated measure analysis of variance with significance achieved at p < .05. RESULTS: During the arm crank exercise, patients reported positive feelings of pleasure. During exercise, heart rate (HR) remained within 80-90% of peak HR. Additionally, patients performed arm crank exercise with moderate levels of perceived exertion (Borg rating of 11-13) and with pleasant affective scores (Feeling Scale of +1 to +5). Blood pressure (systolic, diastolic, and mean) increase was lower after arm crank exercise than for control (greatest net effect: -15 ± 11 mmHg [p < .001]; -9 ± 5 mmHg [p < .001]; -9 ± 6 mmHg [p < .001], respectively), while HR increased (greatest net effect: +9 ± 6 beats per minute; p < .001). CONCLUSION: A single bout of arm crank exercise promotes pleasurable feelings while reducing blood pressure in patients with symptomatic PAD.
