Assessment of cardiorespiratory fitness using submaximal protocol in older adults with mood disorder and Parkinson's disease

Abstract

Background: Evidence has shown benefits for mental health through aerobic training oriented in percentage of VO 2max , indicating the importance of this variable for clinical practice. Objective: To validate a method for estimating VO 2max using a submaximal protocol in elderly patients with clinically diagnosis as major depressive disorder (MDD) and Parkinson's disease (PD). Methods: The sample comprised 18 patients (64.22 ± 9.92 years) with MDD (n = 7) and with PD (n = 11). Three evaluations were performed: I) disease staging, II) direct measurement of VO 2max and III) submaximal exercise test. Linear regression was performed to verify the accuracy of estimation in VO 2max established in ergospirometry and the predicted VO 2max from the submaximal test measurement. We also analyzed the correlation between the Bland-Altman procedures. Results: The regression analysis showed that VO 2max values estimated by submaximal protocol associated with the VO 2max measured, both in absolute values (R 2 = 0.65; SEE = 0.26; p < 0.001) and the relative (R 2 = 0.56; SEE = 3.70; p < 0.001). The Bland-Altman plots for analysis of agreement of showed a good correlation between the two measures. Discussion: The VO 2max predicted by submaximal protocol demonstrated satisfactory criterion validity and simple execution compared to ergospirometry.

Chronic Effects of Different Intensities of Interval Training on Hemodynamic, Autonomic and Cardiorespiratory Variables of Physically Active Elderly People

“…About cardiorespiratory assessment, the IT was shown to be potential in the results, signi cantly improving (p<0.05) VO 2max 20,53,55 . These ndings are essential, since the elderly reduce approximately 5% and 10% of cardiorespiratory capacity, for active and sedentary individuals, respectively 43 . Considering the magnitudes of the results obtained, visualized by ES, and by the ∆%, our ndings corroborate those found by the studies as mentioned earlier because we found no statistically signi cant difference in the crude analyses (p>0.05).…”

Sintomas Depressivos em Pacientes do Ambulatório de Neurologia do Hospital Universitário Lauro Wanderley

“…É interessante notar que, na categoria de depressão severa, há também uma prevalência de mulheres 15 . A falta de correlação entre distúrbios neurológicos e sintomas depressivos pode estar relacionada à pequena amostra de cada doença, bem como à homogeneidade do impacto global de distúrbios neurológicos em transtornos de humor, conforme descrito na literatura [3][4][5][6]16 . Quanto à intensidade dos sintomas depressivos da amostra analisada, observou-se que mais de metade dos pacientes (51,9%) apresentam sintomas depressivos mínimos (sendo quase assintomáticos), enquanto 48% dos pacientes apresentam sintomas depressivos de leve a grave.…”

“…Isso pode ser observado nas demências de Pick, Doença de Alzheimer, doença de Parkinson, de Huntington, esclerose múltipla, neurossífilis, encefalites, entre outras. Essa correlação também associa fibromialgia e epilepsia, estresse e convulsões ou surtos de esclerose múltipla [3][4][5][6][7] . Pacientes com dor crônica, em geral, têm comorbidade psiquiátrica; desses, 30% a 54% fecham os critérios para a depressão 8 .…”
