O tempo para 1,0mm de depressão do segmento ST (T-1,0mm) adotado para caracterizar o fenômeno do aquecimento, uma expressão do precondicionamento isquêmico (PCI), em testes ergométricos sequenciais é consistente e reprodutível, porém, possui várias limitações. O objetivo deste estudo foi aplicar um escore eletrocardiográfico de isquemia miocárdica em testes ergométricos sequenciais comparando com o clássico índice T-1,0mm. Avaliamos 61 pacientes, com idade média de 62,2+7,5 anos, 86,9% homens, portadores de diabetes mellitus tipo 2 e coronariopatia multiarterial. Foram analisados 151 exames, destes 116 de pacientes completaram as duas fases de avaliação. A primeira fase compreendia dois testes ergométricos sequenciais para documentação do PCI e a segunda fase, após 1 semana, mais dois testes sob efeito de repaglinida oral. Dois observadores aplicaram o escore de forma cega. Observou-se concordância perfeita inter e intraobservador (Kendall Tau-b = 0,96, p<0,0001, Kendall Tau-b=0,98, p<0,0001, respectivamente). Os valores de sensibilidade, especificidade, valor preditivo negativo, valor preditivo positivo e acurácia, foram respectivamente de 72,41%, 89,29%, 75,8%, 87,5% e 81%. Concluímos que o escore de isquemia é um método consistente e reprodutível para documentação do fenômeno do aquecimento, representando uma alternativa factível ao índice T-1,0mm. / The time to 1.0mm ST-segment depression (T-1.0mm), adopted to document the warm-up phenomenon, an expression of the ischemic preconditioning (IPC), during sequential exercise tests is considered reliable and reproductible, although with several limitations. The main goal of this study was to apply an electrocardiographic ischemic myocardium score to sequential exercise tests, comparing with the standard T-1.0mm. We evaluated 61 patients, mean age 62,2+7,5 years-old, 86.9% male, with type 2 diabetes mellitus and multivessel coronary disease. We analyzed 151 exercise tests, being 116 tests from patients who fulfilled the two phases of the study. The first phase enrolled the patients for two sequential exercise tests to document the IPC and the second phase, after 1 week, two additional sequential exercise tests were performed under repaglinide treatment. We observed a perfect concordance inter and intraobserver (Kendall Tau-b=0.96, p<0.0001; Kendall Tau-b=0,98, p<0,0001, respectively). The sensibility, specificity, positive predictive value and negative predictive value were also determined: 72.41%, 89.29%, 75.8%, 87.5% and 81%, respectively. In conclusion, the electrocardiographic ischemic score is a consistent and reproductible tool to document the warm-up phenomenon, representing a reliable alternative to the T-1.0mm.

O teste de exercício cardiopulmonar incremental (TECP) tem sido utilizado para avaliar o impacto global da doença em pacientes com DPOC. Considerando que as avaliações de exercício em laboratório são demoradas, caras e muitas vezes indisponíveis, o teste de caminhada de seis minutos (TC6min) não exige equipamentos caros e sofisticados, e pode ser facilmente realizado. Embora, a principal medida comumente utilizada no teste de caminhada seja a distância percorrida durante os 6 minutos (D), esta medida não leva em conta as diferenças de peso corpóreo, que podem influenciar o desempenho do exercício. Além disso, estudos anteriores correlacionaram o trabalho realizado durante o TC6min com TECP incremental pedalando, modalidade de exercício comumente associada a fadiga de quadríceps e menor consumo de oxigênio de pico ( O2) do que o TECP caminhando. O principal objetivo desse estudo foi avaliar a correlação entre a distância percorrida no TC6min (D) e o produto distância percorrida - peso corporal (DxP), uma estimativa do trabalho realizado durante o TC6min, com o O2 de pico obtido durante o TECP incremental em esteira ergométrica. Foram estudados trinta pacientes (19 homens), apresentando média (± DP) de idade de 66,3 ± 7,5 anos, com DPOC estável de moderada a grave intensidade (VEF1 médio de 1,1 ± 0,4L e 39 ± 13% predito) que realizaram TECP incremental em esteira ergométrica até o limite máximo de tolerância e o TC6min. Os testes foram realizados com pelo menos 48 horas de intervalo. A correlação de Pearson foi utilizada para avaliar o nível de associação entre o O2 pico, a distância e o trabalho executado durante o TC6min. Os pacientes percorreram 425,1 ± 78,6 m e realizaram um trabalho de 28166,4 ± 8368,4 Kg-m durante o TC6min, enquanto que o O2 de pico atingido foi 965,6 ± 370,1 mL/min (68,7 ± 17,4% do previsto) no TCPE. Ao final do exercício, em ambos os testes, a dispnéia foi a principal queixa e maior percepção de dispnéia e maior frequência cardíaca foi observado ao final do TECP comparativamente ao TC6min. O trabalho da caminhada (DxP) durante o TC6min demonstrou maior correlação com o O2 pico do que a distância (D) isoladamente. O mesmo ocorreu para VEF1, CVF, CI, DLCO, CO2, E e duplo produto (uma estimativa do trabalho do miocárdio), (r = 0,57; r = 0,57; r = 0,73; r = 0,7; r = 0,75; r = 0,65; r = 0,51; r = 0,4 respectivamente, todos com p <0,05). Dessa forma, esse estudo corrobora a melhor associação entre o trabalho estimado a partir da TC6min e o O2 pico atingido durante TECP, neste caso em esteira ergométrica, em comparação à distância isoladamente. / Incremental cardiopulmonary exercise testing (CPET) is increasingly used to evaluate the overall impact of the illness in patients with COPD. Whereas laboratory tests of exercise performance are often time-consuming, costly and frequently unavailable, the six-minute walk test (6MWT) does not require expensive or sophisticated equipments, and can be easily performed. Although, the main outcome measure commonly used in this field test is the distance walked during the predetermined 6 minutes (6MWD), this measure does not account for differences in body weight that are known to influence exercise performance. Furthermore, previous studies correlated the working performed during 6MWT with incremental cycling CPET, an exercise modality more associated with quadriceps fatigability and lower peak oxygen consumption ( O2) than incremental walking tests. The main objective of this study is to evaluate the correlation between 6MWD and its derivative walking distance-body weight product, an estimation of the work performed during 6MWT, with peak O2 obtained during a treadmill incremental CPET. The study enrolled thirty patients (19 males), with a mean (± SD) age of 66.3 ± 7.5 years and a stable moderate-to-severe COPD (ie, mean FEV1 1.1 ± 0.4L and 39 ± 13 % predicted) performed a ramp incremental CPET to the limit of tolerance on a treadmill and 6MWT. Tests were performed at least 48 h apart. Pearson´s correlation was used to assess the level of association between peak O2 and the distance and work executed during 6MWT. The patients walked 425.1 ± 78.6 m and performed a work of 28,166.4 ± 8368.4 (Kg-m) during the 6MWT while achieved a peak O2 of 965.6 ± 370.1 mL/min (68.7 ± 17.4% of predicted) in the treadmill CPET. They mainly stopped exercise due to dyspnea in both tests and reported a greater perception of dyspnea and higher heart rate was observed at the end of the CPET. The work of walking during the 6-MWT (DxW) provided greater and more frequent significant correlation with peak O2 than that observed with 6MWD.This was the case for FEV1, FVC, IC, DLCO, CO2, E, and double product (an estimate of myocardial work) (r=0.57; r=0.57; r=0.73; r=0.7; r=0.75; r=0.65; r=0.51 and r= 0.4, respectively; all p<0.05). This study provides evidence to corroborate the better association between the work estimated from the 6MWT and peak O2 achieved during CPET, in this case with a treadmill, than the 6MWD on isolation.

INTRODUÇÃO: A obesidade em seus diversos graus é um fator que diminuiu a capacidade de deslocamento motor, reduzindo a capacidade funcional. A utilização de índices de composição corporal total e segmentar em obesos poderá estimar com mais precisão, que o índice de massa corporal (IMC), a capacidade funcional durante deslocamento motor pelo teste de caminhada de seis minutos (TC6). OBJETIVO: Correlacionar a distância percorrida no TC6 (DTC6) com o IMC e com a composição corporal total e segmentar de acordo com a gravidade da obesidade. MÉTODOS: A capacidade funcional foi avaliada em 90 pacientes com obesidade grave (grupo obesos mórbidos: OM e superobesos: SO, por meio da DTC6 e a composição corporal através da impedância bioelétrica (%). RESULTADOS: Na obesidade grave a DTC6 apresentou correlação positiva e significativa (p < 0,05) com a massa livre de gordura (MLG, r = 0,5), massa livre de gordura dos membros superiores (MLG_MS, r = 0,4), tronco (MLG_TR, r = 0,3), membros inferiores (MLG_MI, r = 0,5) e correlação negativa e significativa (p < 0,05) com o IMC (r = -0,3), massa de gordura (MG, r = -0,5), massa de gordura dos membros superiores (MG_MS, r = - 0,4), tronco (MG_TR, r = -0,3) e membros inferiores (MG_MI, r = -0,5). O grupo OM apresentou uma DTC6 superior (524,7 ± 44,0 m, p = 0,014) ao grupo SO (494,2 ± 57,0 m). Não foi encontrada correlação da DTC6 com o IMC quando os pacientes foram classificados de acordo com a gravidade da obesidade. No grupo OM a DTC6 apresentou correlação positiva e significativa (p < 0,05) com a MLG, MLG_MS, MLG_MI (r = 0,4), MLG_TR (r = 0,3) e correlação negativa e significativa (p < 0,05) com a MG, MG_MS (r = -0,4) e MG_TR (r = -0,3). No grupo SO foi encontrada correlação positiva e significativa (p < 0,05) com a MLG (r = 0,5), MLG_TR, MLG_MI (r = 0,4) e correlação negativa e significativa (p < 0,05) com a MG (r = -0,5), MG_TR e MG_MI (r = -0,4). CONCLUSÕES: A massa livre de gordura corporal total e segmentar indicam melhor capacidade funcional, enquanto a massa de gordura corporal total e segmentar indicam pior capacidade funcional na obesidade grave. O IMC não é o melhor preditor de desempenho funcional de acordo com a gravidade da obesidade. Melhor capacidade funcional é apontada pela MLG_MS, MLG_TR e MLG_MI no grupo OM e MLG_TR, MLG_MI no grupo SO e pior capacidade funcional esta correlacionada com a MG_MS e MG_TR no grupo OM e MG_TR, MG_MI no grupo SO / BACKGROUND: Obesity in various degrees is a factor that reduced the capacity of engine displacement, reducing the functional capacity. The use of variables of the total and segmental body composition in obese can estimate more accurately, than body mass index (BMI), functional capacity by the sixminute walk test (6MWT). OBJECTIVE: To correlate the distance walked during the six-minute walk test (6MWD) with body mass index and total and segmental body composition according to the severity of obesity. METHODS: Functional capacity was assessed with 6MWD and body composition (%) by bioelectrical impedance analysis in 90 patients with severe obesity (morbid obese group: MO and super obese group: SO). RESULTS: In severe obesity, 6MWD showed a significant positive correlation (p < 0.05) with fatfree mass (FFM, r = 0.5), fat-free mass of upper limbs (FFM_UL, r = 0.4), trunk (FFM_TR, r = 0.3), lower limbs (FFM_LL, r = 0.5) and a significant negative correlation (p <0.05) with BMI (r = -0.3), fat mass (FM, r = -0.5), fat mass of upper limbs (FM_UL, r = -0.4), trunk (FM_TR, r = -0.3) and lower limbs (FM_LL, r = -0.5). The MO group showed a higher 6MWD (524.7 ± 44.0 m, p = 0.014) than the SO group. There wasn\'t correlation between 6MWD and BMI when patients were stratified according to the severity of obesity. In the MO group there was a significant positive correlation (p < 0.05) with the FFM, FFM_UL, FFM_LL (r = 0.4), FFM_TR (r = 0.3) and a significant negative correlation (p < 0.05) with FM, FM_UL (r = -0.4) and FM_TR (r = - 0.3). In the SO group there was a significant positive correlation (p <0.05) with FFM (r = 0.5), FFM_TR, FFM_LL (r = 0.4) and a significant negative correlation (p < 0.05) was found with FM (r = -0.5), FM_TR and FM_LL (r = - 0.4). CONCLUSION: The total and segmental fat free mass indicates better functional capacity, while total and segmental body fat mass indicates worse functional capacity in severe obesity. BMI is not the best functional predictor according to the severity of obesity. Better functional capacity is correlated by FFM_UL, FFM_TR and FFM_LL in MO group and FFM_TR, FFM_LL in SO and worse functional capacity by FM_UL and FM_TR in MO and FM_TR and FM_LL in SO group

Introdução: A capacidade de exercício tem sido pouco estudadaem pacientes combronquiolite obliterante pós-infecciosa (BOPI). Além disso, há poucos estudos avaliando indivíduos após a infância. Objetivos: Avaliar a capacidade aeróbia máxima em pacientes adolescentes e adultos com diagnóstico prévio de BOPI e identificar os mecanismos de limitação ao exercício. Métodos: Estudo transversal com recuperação retrospectiva de testes espirométricos de 4-6 anos antes dos atuais. Foram estudados 16 pacientes com BOPI (10-23 anos), acompanhados em um ambulatório de atendimento terciário. Todos os indivíduos realizaram teste de função pulmonar em repouso e teste de exercício cardiopulmonar com pesquisa de broncoespasmo induzido pelo exercício (BIE). Um grupo composto de 10 indivíduos saudáveis, pareado por sexo, idade e altura, foi usado como controle. Resultados: Quando comparados ao grupo controle, os pacientes com BOPI apresentaram pior função pulmonar em repouso, com moderada a grave obstrução ao fluxo de ar e aprisionamento aéreo. Capacidade aeróbica de pico foi significativamente menor nos pacientes ( O2 pico: 87±22 vs 110±21% previsto; p=0,01), com uma maior proporção de pacientes com capacidade aeróbica abaixo do normal [ O2 pico<84% previsto: 7/16(44%) vs 1/10(10%); p= 0,09]. A capacidade aeróbica máxima (expressa tanto em valores absolutos como em % previsto) dos pacientes foi significativamente associada com idade (r=0,59, p=0,02), índice de massa corpórea (IMC) (r=0,55, p=0,03), capacidade difusiva pulmonar (DLCO% previsto) (r=0,66, p=0,01), capacidade inspiratória (CI) / capacidade pulmonar total (CPT) (r=0,52, p=0,04) e volume residual (RV) / CPT (r=-0,56, p=0,03). Nenhuma associação foi encontrada, no entanto, entre a O2 de pico e os valores finais de exercícios e variação da oximetria de pulso (SpO2), relação ventilação de pico/ventilação voluntária máxima( E/VVM) e outros valores da função pulmonar em repouso quando expresso em % do previsto. Por outro lado, o volume expiratório forçado no 1ºs (VEF1) foi moderadamente correlacionado com DLCO (r=0,59, p=0,03) e fortemente com CI/CPT (r=0,90, p=0,00) e VR/CPT (r=-0,89, p=0,00). Valores espirométricos atuais não foram diferentes dos de 4-6 anos atrás, quando expresso em % do previsto [VEF1: 60±30 vs 60±22; capacidade vital forçada (CVF): 73±22 vs 69±14], embora, quando expresso em litros, valores atuais foram maiores (VEF1: 1,94±0,93 vs 1,14±0,50; CVF: 2,79±0,89 vs 1,52±0,45, p<0,01). Conclusão: Pacientes adolescentes e adultos com BOPI apresentaram uma capacidade aeróbia de pico reduzida em comparação comcontroles saudáveis, sendo que aproximadamente metade dos pacientes tiveram redução da capacidade aeróbica quando expresso em porcentagem do previsto. A capacidade aeróbica de pico foi diretamente relacionada com a idade, a capacidade de difusão pulmonar e os parâmetros de hiperinflação pulmonar e aprisionamento aéreo. Quanto maior a limitação do fluxo de ar (menor VEF1) maior foi a hiperinsuflação e aprisionamento aéreo. / Introduction: Repercussion in exercise capacity has been poorly studied in patients with post-infectious bronchiolitis obliterans (PBO). Additionally, studies have mainly evaluated children and a follow-up in older subjects is lacking. Aims: Evaluate with maximal incremental cardiopulmonary exercise tests older adolescents and adults with previous diagnosis of PBO and indentify the mechanisms of exercise limitation. Methods: The study has a cross-sectional design with retrospective retrieval of the available spirometric data of 4-6 years ago. We studied 16 patients with POB (10 to 23 yrs old), followed up inan outpatient tertiary care clinic. All subjects underwent resting lung function testingand exercise testing. A control group, composedbysex, age and height, was usedcontaining 10subjects. Results: When compared PBO patients with control group, patients presented worse resting lung function, with moderate-to-severe air flow obstruction and air trapping. Peak exercise capacity was significantly lower in patients (peak O2: 87±22 vs 110±21% pred; P=0.01) with a greater proportion than in patients presenting reduced aerobic capacity [peak O2<84% pred: 7/16(44%) vs 1/10(10%); p= 0.09]. In correlations analyses, peak aerobic capacity (expressed both as absolute values and %pred) was significantly correlated with age in patients (r= 0.59, p= 0.02), body mass index (BMI) (r= 0.55, p= 0.03), lung diffusion capacity (DLCO% pred) (r= 0.66, p= 0.01), rest inspiratory capacity(IC)/total lung capacity(TLC) (r= 0.52, p=0.04) and residual volume (RV)/TLC (r= -0.56, p= 0.03). No association was found, however, between peak O2 and final exercise values and change from rest of SpO2 (p=0.79 and 0.76, respectively) peak ventilation/maximal ventilatory ventilation ratio ( E/MVV) (p=0.82) and other resting lung function values [forced expiratory volume in 1s (FEV1), forced vital capacity (FVC), FEV1/FVC, IC, TLC and RV) when expressed as %pred. On the other hand, FEV1 were moderately correlated with DLCO (r= 0.59, p= 0.03), and strongly with IC/TLC (r= 0.90, p= 0.00) and RV/TLC (r= -0.89, p= 0.00). Current spirometric values were not different from those of 4-6 years ago when expressed as % of pred (FEV1: 60±30 vs 60±22; FVC: 73±22 vs 69±14), although when expressed in liters, current values are greater (FEV1: 1.94±0.93 vs 1.14±0.50; FVC: 2.79±0.89 vs 1.52±0.45; p= 0.00 and 0.00, respectively). Conclusion: We have shown in a sample of adolescent and adult patients with PBO that peak aerobic capacity is reduced compared to healthy controls and almost half of the patients had reduced aerobic capacity when expressed as percent of predict. Peak aerobic capacity was directly correlated with age, lung diffusion capacity and parameters of rest hyperinflation and air trapping. The greater the air flow limitation (lower FEV1), the greater the hyperinflation and air trapping were.

Objetivos: O exercício físico regular em pacientes com fibrose cística (FC) auxilia no condicionamento aeróbico e diminui a progressão da doença, proporcionando melhor qualidade de vida. O objetivo desse estudo foi avaliar os efeitos de um programa de exercício físico aeróbico baseado na orientação verbal e instrumental na capacidade funcional e na qualidade de vida. Métodos: O Estudo constituiu-se de um ensaio clínico, randomizado, de orientações para o exercício físico realizado em um centro de FC. Os pacientes foram alocados em dois grupos, intervenção e controle, sendo 17 pacientes no grupo intervenção (G1) e 17 para o grupo controle (G2). A coleta de dados ocorreu durante o período de outubro de 2010 a outubro de 2011, e a população em estudo consistiu em crianças e adolescentes com FC e idade entre sete e 20 anos.A intervenção foi um manual de orientações com exercícios físicos aeróbicos e reforço das orientações por meio de contato telefônico a cada duas semanas. Resultados: Foram estudados 34 pacientes com FC, sendo que 20 pacientes (58,8)% eram do sexo masculino. Os grupos eram semelhantes no momento basal, sendo que no G1 seis pacientes (35,2%) referiram praticar exercício físico regularmente, a média de idade foi de 13,40±2,81 anos, do percentual do previsto do volume expiratório forçado no primeiro segundo (VEF1%) foi de 95,53±17,94 % e do consumo de oxigênio de pico relativo a massa corporal (VO2pico) foi de 34,93±9,09 ml/kg-1.min-1 . No G2, quatro pacientes (23,5%) referiram praticar exercício físico regularmente, a média de idade foi de 12,76±3,37 anos, do VEF1 foi de 100,13±21,27 % e do VO2pico foi de 33,21±8,26 ml/kg-1.min. Houve aumento significativo do G1 na prática de exercício físico relatada pelos pacientes após os três meses de intervenção comparado ao G2 (p=0,013). Nas demais variáveis não foram observadas diferenças estatisticamente significativas. Conclusão: Esse estudo demonstrou que a orientação verbal e instrumental para o exercício aeróbico, acoplado com supervisão telefônica teve impacto positivo no relato das crianças e adolescentes quanto a prática do exercício físico regular. Porém, não foram observados melhora nos parâmetros fisiológicos, nem nos domínios do questionário de qualidade de vida. / Objectives: Regular physical activity in patients with cystic fibrosis (CF) improves aerobic conditioning and delays disease progression, which results in better quality of life. This study evaluated the effect on functional capacity and quality of life of an aerobic physical activity program based on verbal and written guidelines. Methods: This randomized clinical trial used guidelines for physical exercise in a CF center. Patients were assigned to two groups: intervention (G1), with 17 patients; and control (G2), also with 17 patients. Data were collected from October 2010 to October 2011, and the study population comprised children and adolescents with CF aged 7 to 20 years. The intervention consisted of handing out a manual with guidelines for aerobic physical exercises and reinforcing recommendations in contacts by phone every two weeks. Results: Thirty-four patients were included in the study, 20 of whom were boys (58.5%). The groups were similar at baseline. In G1, 6 patients (35.2%) reported practicing physical exercises regularly; mean age was 13.40±2.81 years, mean percent predicted forced expiratory flow at one second (FEV1%) was 95.53±17.94% and mean peak oxygen uptake (VO2peak) relative to body mass was 34.93±9.09 ml/kg-1.min-1. In G2, four patients (23.5%) reported practicing physical exercises regularly. Mean age was 12.76±3.37 years, mean FEV1 was 100.13±21.27% and mean VO2peak was 33.21±8.26 ml/kg-1.min. In G1, there was a significant increase of physical exercise practice as reported by patients after three months of intervention when compared with G2 (p=0.013). No statistically significant differences were found for the other variables. Conclusion: Verbal and written guidelines for aerobic exercise, together with supervision over the phone, had a positive impact on the report of regular physical exercise practice by children and adolescents. However, no improvement was found in physiological parameters or domains of the quality of life questionnaire.

<p>During the past few years there has been an observed decrease in physical fitness within different patient groups. As a part of the rehabilitating physiotherapy treatment it is important to acknowledge the physical condition of the patient. Physical fitness testing might be difficult due to physical limitations within different patient groups. A broad range of exercise tests is therefore of importance in clinical practice. The aim of this overview was to describe exercise tests used in rehabilitation contexts, and to define areas of use and restrictions. The method was a systematic literature overview and data was gathered through medical and healthcare databases. Scientific articles were selected and put together to answer the questions in the overview. The result showed that exercise tests mainly described in the literature were tests performed on a bicycle ergometer, treadmill tests and walking tests. The tests were in several cases combined with rating scales. The tests were performed as submaximal or maximal tests to estimate VO₂max or VO₂Peak. Exercise testing was commonly used in rehabilitation of cardiac- and vascular diseases, pulmonary diseases and spinal cord injuries. Evaluation of an exercise program was the most common reason for using an exercise test. The question concerning restrictions of the tests could not be answered. The conclusion was that the most common exercise test was performed on a bicycle ergometer. Maximal VO₂Peak or VO₂max testing were mainly performed. The most common area for exercise testing was cardiac- and vascular rehabilitation. The most common purpose for performing an exercise test was evaluation of an exercise program. Further research is required in order to describe restrictions and implementations of the tests.</p>

To assess the relationships of body mass index (BMI) on arterial stiffness at rest and post-maximal treadmill graded exercise testing (GXT). Forty-four apparently healthy, young adult males (22.1 ± 0.48 years) were recruited and divided into either a healthy weight (H, ≤24.9 kg/m2), overweight (OV, 24.9-29.9 kg/m2) or obese (OB, ≥29.9 kg/m2) group based on BMI. All subjects underwent arterial stiffness (carotid-femoral pulse wave velocity, cfPWV), blood pressure (BP), pulse pressure (PP), mean arterial pressure (MAP) and body composition (bioelectrical impedance analysis, BIA) measurements at rest. Following the GXT, measures of arterial stiffness (cfPWV) and BP were acquired. Resting measures of cfPWV, BMI, systolic BP, diastolic BP, MAP, and PP were significantly (p <0.05) greater in OV and OB compared with H. Compared with OV, OB had a greater BMI. Relative peak oxygen consumption (VP2peak) was greater in H compared with OV and OB (p<0.05). systolic BP was positively associated, whereas VO2peak was inversely related to cfPWV (p<0.05). No significant inter-group interactions were observed with cfPWV after the GXT. However, interactions were observed for SBP, DBP and PP (p<0.05). In young men with varying BMI, SBP and VO2peak were associated with resting cfPWV. However, similar cardiovascular responses were observed between groups after a maximal GXT.
