Cardiovascular, perceived exertion and affective responses during aerobic exercise performed with imposed and a self-selected intensity in patients with Parkinson’s disease

Abstract

BACKGROUND: Exercise with self-selected intensity (SSI) has emerged as a new strategy for exercise prescription aiming to increase exercise adherence in Parkinson’s disease (PD). OBJECTIVE: We compared the cardiovascular, perceived exertion and affective responses during traditional aerobic exercise and with SSI in PD. METHODS: Twenty patients with PD performed two aerobic exercise sessions in random order with an interval of at least 72 h between them: Traditional session (cycle ergometer, 25 min, 50 rpm) with imposed intensity (II) (60–80% maximum heart rate [HR]) and SSI: (cycle ergometer, 25 min, 50 rpm) with SSI. The HR (Polar V800 monitor), systolic blood pressure (auscultatory method), rating of perceived exertion (Borg scale 6–20) and affective responses (feeling scale) were assessed during the exercise at 8th and 18th minute. The Generalized Estimating Equation Model was used for comparison between both sessions (P < 0.05). RESULTS: The exercise intensity was not significantly different between both exercise sessions (8th minute: II –76.3±1.0 vs. SSI –76.5±1.3 % of maximal HR; 18th minute: II –78.9±0.9 vs. SSI –79.1±1.3 % of maximal HR, p = 0.93). Blood pressure, perceived exertion and affective responses were also not significantly different between both sessions (P > 0.05). CONCLUSIONS: Cardiovascular and psychophysiological responses were not different during aerobic exercise performed with II and with SSI in patients with PD.

Walking Intensity Preference of Patients With Peripheral Arterial Disease

“…There were no significant differences in exercise intensity markers such as HR and RPE between the two sessions. This finding aligns with previous studies that reported similar results for self-selected and imposed exercise intensities in other populations 9,10. Furthermore, the majority of patients maintained an HR >50% of their estimated maximal HR during both sessions, consistent with a prior study11 of PAD patients with claudication symptoms who exercised at the pain threshold and demonstrated HR ranging from 60-82% of maximal HR during the exercise session.…”

Comparison of Psychophysiological Responses in Individual and Small Group Aerobic Training with Prescribed and Self-Selected Intensity

“…The present study analyzed psychophysiological responses in individual and small group aerobic training with prescribed and self-selected intensities. Corroborating our primary hypothesis, we found that the self-selected intensity compared to the moderate intensity prescribed in aerobic training did not present significant differences in HR, LACT, RPE, FAS, PACES, TS and TD (p>0.05) [22,23].…”

“…The intensity of aerobic exercise is related to the perception of pleasure or displeasure during exercise [8,10,13,22]. Such perceptions are expressed by the affective response, which appears to predict future participation in exercise programs [12].…”

Acute Cardiovascular Responses to Self-selected Intensity Exercise in Parkinson's Disease

“…All patients performed three experimental sessions (control [C], TRAD, and SSI), which were conducted in a random order and with an interval of at least 72 h between sessions, as previously described [22]. Before the sessions, patients were instructed not to exercise in the previous 48 h, to eat a light meal 2 h before, to avoid caffeinated beverages on the testing days, and to take their PD medication 30 min before the start of the sessions.…”
