Association between anaerobic components of the maximal accumulated oxygen deficit and 30-second Wingate test BJMBR
Bertuzzi,R.; Kiss,M.A.P.D.M.; Damasceno,M.; Oliveira,R.S.F.; Lima-Silva,A.E..
The purpose of this study was to analyze the relationship between the anaerobic components of the maximal accumulated oxygen deficit (MAOD) and of the 30-second Wingate anaerobic test (30-WAnT). Nine male physical education students performed: a) a maximal incremental exercise test; b) a supramaximal constant workload test to determine the anaerobic components of the MAOD; and c) a 30-WAnT to measure the peak power (PP) and mean power (MP). The fast component of the excess post-exercise oxygen consumption and blood lactate accumulation were measured after the supramaximal constant workload test in order to determine the contributions made by alactic (ALMET) and lactic (LAMET) metabolism. Significant correlations were found between PP and ALMET (r=0.71;...

Effects of high- and moderate-intensity exercise on central hemodynamic and oxygen uptake recovery kinetics in CHF-COPD overlap BJMBR
Mazzuco,A.; Souza,A.S.; Medeiros,W.M.; Sperandio,P.A.; Alencar,M.C.N.; Arbex,F.F.; Neder,J.A.; Borghi-Silva,A..
The oxygen uptake (V˙O2) kinetics during onset of and recovery from exercise have been shown to provide valuable parameters regarding functional capacity of both chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF) patients. To investigate the influence of comorbidity of COPD in patients with CHF with reduced ejection fraction on recovery from submaximal exercise, 9 CHF-COPD male patients and 10 age-, gender-, and left ventricle ejection fraction (LVEF)-matched CHF patients underwent constant-load exercise tests (CLET) at moderate and high loads. The V˙O2, heart rate (HR), and cardiac output (CO) recovery kinetics were determined for the monoexponential relationship between these variables and time. Within-group analysis showed that...

Respiration rate and its effect on mass loss and chemical qualities of 'Fuyu' persimmon fruit stored in controlled atmosphere Ciência Rural
Brackmann,Auri; Thewes,Fabio Rodrigo; Anese,Rogério de Oliveira; Both,Vanderlei; Gasperin,Adriano Roque de.
The objective of this research was evaluate the effect of two CO2 partial pressures in ultra-low oxygen on the mass loss in function of respiration, oxygen consumption, respiratory rate and other characteristics of 'Fuyu' persimmon during 12 weeks in controlled atmosphere (CA) storage at temperature of -0,5°C. For thus, one experiment was carried out with the followed CA condition: [1] 0.15 kPa O2 plus 2.0 kPa CO2 and [2] 0.15 kPa O2 plus 6.0 kPa CO2. On this study was verified that the respiration (carbon dioxide production) was responsible for 24% of total mass loss. The total mass loss is significantly affected by the controlled atmosphere storage. The 2.0 kPa CO2 promotes changes in the respiratory quotient during the storage period and keep higher...

Validation of the two-minute step test in obese with comorbibities and morbidly obese patients BJMBR
Ricci,P.A.; Cabiddu,R.; Jürgensen,S.P.; André,L.D.; Oliveira,C.R.; Di Thommazo-Luporini,L.; Ortega,F.P.; Borghi-Silva,A..
Cardiopulmonary fitness assessment is a valuable resource to obtain quantitative indicators of an individual's physical performance. The cardiopulmonary exercise test (CPX), considered the gold standard test for this evaluation, is costly and difficult to be accessed by the general population. In order to make this evaluation more accessible, and to better reflect the performance of daily life activities, alternative tests were proposed. Morbidly obese patients present limitations that impair physical performance assessment and could benefit from a test of shorter duration, provided it is validated. This observational study aimed to validate the two-minute step test (2MST) as a tool to evaluate functional capacity (FC) in obese with comorbidities and...
