Little information is available about the physical fitness of opera singers. The aim of this study is to measure cardiac engagement during rehearsals and to test both cardiovascular fitness and body composition in a group of opera singers. Thirty-two opera singers (17 female and 15 male) were enrolled for the assessment of body composition by bio impedance, of cardiovascular fitness by submaximal exercise test on a cycle ergometer and the physical effort during singing. Anthropometric parameters showed an overweight condition mainly due to an increase in fat mass. Watts reached during the cycle ergometer test were below the normal range for the general population. During rehearsals, singers have reached 95% of the maximum heart rate. Nowadays, opera singers show low levels of physical fitness, but singing is an activity that requires a high heart effort. Therefore, it is recommended to involve such professionals in a gradual and individualized physical training program in order to avoid fatigue during performances and achieve a better singing performance.

El objetivo del presente estudio fue evaluar los efectos de un programa de ejercicio físico sobre la presión arterial, el perfil lipídico y la condición física en 16 adultos (9 hombres, 7 mujeres; 54 ± 5 años) prehipertensos, sin la presencia de otra enfermedad crónica. El grupo participó en un programa de ejercicios físicos aeróbico y de fuerza durante 16 semanas, 1.5 horas, 3 veces por semana. La presión arterial, el perfil lipídico, la condición física y medidas antropométricas fueron evaluadas al inicio y al final del programa. El test de Wilcoxon-Cox se utilizó para evaluar los cambios pre-post en las variables. Se encontraron disminuciones estadísticamente significativas en la presión arterial sistólica y diastólica basal de ~12/9 mmHg (p < .05) respectivamente, el VO2 pico incrementó ~8 ml/Kg/min (p < .05), la potencia en cicloergómetro aumentó ~51 Watts (p < .05); el IMC decreció ~2 puntos (p < .05); triglicéridos disminuyeron ~21 mg/dL (p < .05); colesterol disminuyó ~19 mg/dL (p < .05); HDL incrementó ~10 mg/dL (p < .05) y LDL decreció ~36 mg/dL (p < .05). Conclusiones: el programa de ejercicios físicos produjo mejoras significativas en la presión arterial, el perfil lipídico y la condición física en este grupo de adultos prehipertensos.Palabras clave. hipertensión arterial, ejercicio, condición física, lípidos.Abstract. The purpose of the study was to determine the effect of a physical exercise program on blood pressure, lipid profile and physical fitness on 16 (9 men, 7 women; 54 ± 5 years old) prehypertensive adults, without any other chronic illness. The group followed a physical exercise program for 16 weeks, which last 1.5 hour, three times a week consisting of aerobic activities and strength training. Blood pressure, lipid profile, physical fitness and anthropometric measurements were assessed pre and post training. Wilcoxon-Cox test was used to compare within group changes. Statistically significant reductions were found in basal systolic and diastolic blood pressure by ~12/9 mmHg (p < .05) respectively; VO2 peak increased by ~8 ml/Kg/min (p < .05); the peak power achieved during the cycle-ergometer test increased by ~51 Watts (p < .05); BMI decreased by ~2 points (p < .05); triglycerides decreased by ~21 mg/dL (p < .05); cholesterol decreased by ~19 mg/dL (p < .05); HDL increased by ~10 mg/dL (p < .05); LDL decreased by ~36 mg/dL (p < .05). Conclusions: this intervention showed significant improvements in blood pressure, lipid profile and physical fitness in this group of adults with prehypertension.Key words. arterial hypertension, exercise, physical fitness, lipids.

The effect of beta-adrenergic blockade on the drift in O2 consumption (VO2 drift) typically observed during prolonged constant-rate exercise was studied in 14 healthy males in moderate heat at 40% of maximal O2 consumption (VO2max). After an initial maximum cycle ergometer test to determine the subjects' control VO2max, subjects were administered each of three medications: placebo, atenolol (100 mg once daily), and propranolol (80 mg twice daily), in a randomized double-blind fashion. Each medication period was 5 days in length and was followed by a 4-day washout period. On the 3rd day of each medication period, subjects performed a maximal cycle ergometer test. On the final day of each medication period, subjects exercised at 40% of their control VO2max for 90 min on a cycle ergometer in a warm (31.7 +/- 0.3 degrees C) moderately humid (44.7 +/- 4.7%) environment. beta-Blockade caused significant (P less than 0.05) reductions in VO2max, maximal minute ventilation (VEmax), maximal heart rate (HRmax), and maximal exercise time. Significantly greater decreases in VO2max, VEmax, and HRmax were associated with the propranolol compared with the atenolol treatment. During the 90-min submaximal rides, beta-blockade significantly reduced heart rate. Substantially lower values for O2 consumption (VO2) and minute ventilation (VE) were observed with propranolol compared with atenolol or placebo. Furthermore, VO2 drift and HR drift were observed under atenolol and placebo conditions but not with propranolol. Respiratory exchange ratio decreased significantly over time during the placebo and atenolol trials but did not change during the propranolol trial.(ABSTRACT TRUNCATED AT 250 WORDS)

AbstractThe purpose of this study was to investigate the correlation between the seismocardiogram and cardiorespiratory fitness. Cardiorespiratory fitness can be estimated as VO2max using non-exercise algorithms, but the results can be inaccurate. Healthy subjects were recruited for this study. Seismocardiogram and electrocardiogram were recorded at rest. VO2max was measured during a maximal effort cycle ergometer test. Amplitudes and timing intervals were extracted from the seismocardiogram and used in combination with demographic data in a non-exercise prediction model for VO2max. 26 subjects were included, 17 females. Mean age: 38.3±9.1 years. The amplitude following the aortic valve closure derived from the seismocardiogram had a significant correlation of 0.80 (p<0.001) to VO2max. This feature combined with age, sex and BMI in the prediction model, yields a correlation to VO2max of 0.90 (p<0.001, 95% CI: 0.83–0.94) and a standard error of the estimate of 3.21 mL·kg−1·min−1 . The seismocardiogram carries information about the cardiorespiratory fitness. When comparing to other non-exercise models the proposed model performs better, even after cross validation. The model is limited when tracking changes in VO2max. The method could be used in the clinic for a more accurate estimation of VO2max compared to current non-exercise methods.
