Resumo: | Introduction. In Brazil, 23% of adolescents aged 13 to 17 years are overweight, and 8% are obese. Obese children and adolescents will potentially be obese adults with a higher chance of developing cardiometabolic diseases. Cardiorespiratory behavior during the cardiopulmonary exercise test (CPT) provides a wealth of information about cardiovascular health. Objective. To test the hypothesis that apparently healthy obese adolescents present decreased functional capacity at maximal (VO2 peak) and submaximal loads (VO2 at 50% of the total time of the test and Oxygen Uptake Efficiency Slope, OUES) and impaired heart rate responses (HR) and systolic (SBP) and diastolic (DBP) blood pressure during exercise and ECP recovery. Methods. 18 obese adolescents (AO; +2 WHO Z-Score, 14.2 ± 0.3 years, 98.0 ± 4.6 kg) from 12 to 17 years old, pubertal, sedentary, who were not Dietary or drug treatment, compared to 11 eutrophic adolescents (EA, 14.9 ± 0.9 years, 55.0 ± 3.2 kg) matched by sex. Clinical BP, metabolic profile and cardiorespiratory behavior were evaluated during CPET. Results. The AO group had greater abdominal circumference and a greater amount and proportion of body fat than the AE group. In addition, AO had higher SBP and DBP and higher triglyceride and LDL-C levels and lower HDL-c levels than AE. In the TECP, the AO group had lower values than AE in the peak VO2 (24.8 ± 1.3 vs. 30.3 ± 2.8 ml / kg / min, P = 0.05) and in the% of the peak VO2 reached In relation to predicted VO2 (56.4 ± 3.5 vs. 70.3 ± 4.9%, P = 0.04). There was no difference in OUES between the groups. During the CPT there were differences in HR only at 50% of peak VO2, where the AO group had higher HR compared to AE (143 ± 4.2 vs. 129 ± 5.4 bpm, P = 0.04). In the AO group, higher SBP values were found at rest, peak, 1st, 2nd and 6th min of recovery, whereas DBP was only higher in the 2nd and 4th minutes of recovery compared to the AE group. In addition, there was a tendency for greater minute ventilation (VEpico) at the peak of effort in the AO (78.1 ± 4.1 vs. 63.3 ± 5.6 L / min, P = 0.06) and there was no difference in VE To 50% of the peak VO2 (26.3 ± 1.6 vs. 22.7 ± 3.1 L / min, P = 0.374). There was no difference between the groups in the maximum respiratory quotient (QR) and maximum HR. Regarding physical performance, the OA group presented lower total exercise time (8.0 ± 0.3 vs. 9.3 ± 0.8 min, P = 0.04), lower speed (7.3 ± 0.1 P = 0.05) and lower slope at peak exercise (6.2 ± 0.5 vs. 8.4 ± 1.1%, P = 0.03 ) Compared to EC. Conclusion. Adolescent obesity triggers metabolic alterations, favoring the onset of the metabolic syndrome. Among these changes, it is worth noting the increase in blood pressure responses at the peak of exercise and a lower decrease in systolic and diastolic blood pressure in the post-exertion recovery, thus suggesting a possible dysfunction in the sympatho-vagal balance. |

No Brasil, 23% dos adolescentes com idade entre 13 a 17 anos estão com excesso de peso, sendo que 8% são obesos. Crianças e adolescentes obesos potencialmente serão adultos obesos e com maiores chances de desenvolverem doenças cardiometabólicas. O comportamento cardiorrespiratório durante o teste de esforço cardiopulmonar (TECP) fornece informações sobre a saúde cardiovascular, auxiliando em sua manutenção, que pode ser comprometida pela obesidade. Objetivo: Testar a hipótese que adolescentes obesos, aparentemente saudáveis, apresentam diminuição da capacidade funcional em cargas máximas (VO2 pico) e submáximas (VO2 aos 50% do tempo total do teste e Oxygen Uptake Efficiency Slope, OUES) e respostas prejudicadas da frequência cardíaca (FC) e da pressão arterial sistólica (PAS) e diastólica (PAD) durante o exercício e na recuperação do TECP. Métodos. Foram estudados 18 adolescentes obesos (AO; +2 Z-Score da OMS; 14,2±0,3 anos, 98,0±4,6 kg) de 12 a 17 anos, pós púberes, sedentários, que não estavam engajados em tratamento dietético ou medicamentoso, comparados a 11 adolescentes eutróficos (AE; 14,9±0,9 anos, 55,0±3,2 kg) pareados por sexo. Foram avaliados a PA clínica, o perfil metabólico e o comportamento cardiorrespiratório durante o TECP. Resultados. O grupo AO apresentou maior circunferência abdominal e maior quantidade e proporção de gordura corporal que o grupo AE. Além disso, AO teve maior PAS e PAD e maiores níveis de triglicérides e LDL-c e menores níveis de HDL-c que AE. No TECP, o grupo AO apresentou valores diminuídos em relação ao grupo AE no VO2 pico (24,8±1,3 vs. 30,3±2,8 ml/kg/min; P=0,05) e na % do VO2 pico atingido em relação ao VO2 predito (56,4±3,5 vs. 70,3±4,9%; P=0,04). Não houve diferença no OUES entre os grupos. Durante o TECP houve diferenças na FC apenas em 50% do VO2 pico, momento em que o grupo AO teve maior FC comparado com AE (143±4,2 vs. 129±5,4 bpm, P=0,04). No grupo AO, foram encontrados valores mais altos de PAS no repouso, pico, 1º, 2º e 6º min de recuperação, enquanto que a PAD só se mostrou maior nos 2º e 4º minutos da recuperação comparado com o grupo AE. Adicionalmente, houve tendência a maior ventilação minuto (VEpico) no pico do esforço no AO (78,1±4,1 vs. 63,3±5,6 L/min, P=0,06) e não houve diferença na VE aos 50% do VO2 pico (26,3±1,6 vs. 22,7±3,1 L/min, P= 0,374). Não houve diferença entre os grupos no quociente respiratório (QR) máximo e na FC máxima. Quanto ao desempenho físico, o grupo AO apresentou menor tempo total de exercício (8,0±0,3 vs. 9,3±0,8 min, P=0,04), menor velocidade (7,3±0,1 vs. 8,0±0,4 km/h, P=0,05) e menor inclinação no pico de esforço (6,2±0,5 vs. 8,4±1,1 %, P=0,03) comparado ao AE. Conclusão. A obesidade na adolescência desencadeia alterações metabólicas, favorecendo o surgimento da síndrome metabólica, dentre essas alterações, vale ressaltar valores reduzidos de VO2 pico, o aumento das respostas pressóricas no pico do exercício e menor queda da pressão arterial sistólica e diastólica na recuperação pós-esforço máximo, sugerindo assim uma possível disfunção no balanço simpato-vagal.Submitted by Nadir Basilio (nadirsb@uninove.br) on 2022-07-27T19:36:23Z No. of bitstreams: 1 Leslie Virmondes da Silva.pdf: 2237964 bytes, checksum: 4fd1fcd7cd0aadc0221ca511f6c764c2 (MD5)Made available in DSpace on 2022-07-27T19:36:23Z (GMT).

Introduction. In Brazil, 23% of adolescents aged 13 to 17 years are overweight, and 8% are obese. Obese children and adolescents will potentially be obese adults with a higher chance of developing cardiometabolic diseases. Cardiorespiratory behavior during the cardiopulmonary exercise test (CPT) provides a wealth of information about cardiovascular health. Objective. To test the hypothesis that apparently healthy obese adolescents present decreased functional capacity at maximal (VO2 peak) and submaximal loads (VO2 at 50% of the total time of the test and Oxygen Uptake Efficiency Slope, OUES) and impaired heart rate responses (HR) and systolic (SBP) and diastolic (DBP) blood pressure during exercise and ECP recovery. Methods. 18 obese adolescents (AO; +2 WHO Z-Score, 14.2 ± 0.3 years, 98.0 ± 4.6 kg) from 12 to 17 years old, pubertal, sedentary, who were not Dietary or drug treatment, compared to 11 eutrophic adolescents (EA, 14.9 ± 0.9 years, 55.0 ± 3.2 kg) matched by sex. Clinical BP, metabolic profile and cardiorespiratory behavior were evaluated during CPET. Results. The AO group had greater abdominal circumference and a greater amount and proportion of body fat than the AE group. In addition, AO had higher SBP and DBP and higher triglyceride and LDL-C levels and lower HDL-c levels than AE. In the TECP, the AO group had lower values than AE in the peak VO2 (24.8 ± 1.3 vs. 30.3 ± 2.8 ml / kg / min, P = 0.05) and in the% of the peak VO2 reached In relation to predicted VO2 (56.4 ± 3.5 vs. 70.3 ± 4.9%, P = 0.04). There was no difference in OUES between the groups. During the CPT there were differences in HR only at 50% of peak VO2, where the AO group had higher HR compared to AE (143 ± 4.2 vs. 129 ± 5.4 bpm, P = 0.04). In the AO group, higher SBP values were found at rest, peak, 1st, 2nd and 6th min of recovery, whereas DBP was only higher in the 2nd and 4th minutes of recovery compared to the AE group. In addition, there was a tendency for greater minute ventilation (VEpico) at the peak of effort in the AO (78.1 ± 4.1 vs. 63.3 ± 5.6 L / min, P = 0.06) and there was no difference in VE To 50% of the peak VO2 (26.3 ± 1.6 vs. 22.7 ± 3.1 L / min, P = 0.374). There was no difference between the groups in the maximum respiratory quotient (QR) and maximum HR. Regarding physical performance, the OA group presented lower total exercise time (8.0 ± 0.3 vs. 9.3 ± 0.8 min, P = 0.04), lower speed (7.3 ± 0.1 P = 0.05) and lower slope at peak exercise (6.2 ± 0.5 vs. 8.4 ± 1.1%, P = 0.03 ) Compared to EC. Conclusion. Adolescent obesity triggers metabolic alterations, favoring the onset of the metabolic syndrome. Among these changes, it is worth noting the increase in blood pressure responses at the peak of exercise and a lower decrease in systolic and diastolic blood pressure in the post-exertion recovery, thus suggesting a possible dysfunction in the sympatho-vagal balance. |
