“…The data obtained by our subjects were within these normal zones, namely, from 10.3 and 8.75 for men and women, respectively, which also corroborates another study 22 similar to ours. In the present study, for each type of exercise which was part of the sessions, individual analysis of the MET and caloric expenditure values was performed, which were classified as moderate, obtaining values range between 3.6 and 5.8 METs.…”

Objective: This study aimed to determine the energy expenditure (EE) in terms of caloric cost and metabolic equivalents (METs) of two sessions of an exercise protocol. Methods: Fifteen subjects (51.0 ± 5.5years) performed the exercise sessions (80min), which were composed by (warming, walking and flexibility exercises; Session A) and (warming, walking and local muscular endurance exercises; Session B). Heart hate (HR) was measured during each part of the sessions. In laboratory environment, maximal oxygen consumption (VO 2max ) and oxygen uptake in rest and exercise conditions (using mean HR obtained in classes) were measured on different days, using indirect calorimetry. Exercise METs were obtained by dividing VO 2 in exercise (mL.kg .min -¹). Conclusion: The proposed protocol achieves the physical activity needed by healthy adults to improve and maintain health, by their structure, moderate intensity, duration, frequency and caloric expenditure.

“…More recently, resistance training with increased volume of movement via increased numbers of sets and/or repetitions has shown a greater impact upon the lipid profile than increased intensity (5,6). In addition, significant positive changes can occur in cardiovascular and metabolic measurements after resistance training (7,8).…”

The objective of this study was to assess cardiovascular, respiratory, and metabolic responses during a commonly used dynamic leg press resistance exercise until exhaustion (TEx) at different intensities and compare with critical load (CL). This was a prospective, cross-sectional, controlled, and crossover study. Twelve healthy young men (23±2.5 years old) participated. The subjects carried out three bouts of resistance exercise in different percentages of 1 repetition maximum (60, 75, and 90% 1RM) until TEx. CL was obtained by means of hyperbolic model and linearization of the load-duration function. During all bout intensities, oxygen uptake (VO2), carbon dioxide production (VCO2), ventilation (VE), and respiratory exchange ratio (RER) were obtained. Variations (peak-rest=Δ) were corrected by TEx. In addition, systolic and diastolic blood pressure (SBP and DBP), blood lactate concentration [La-] and Borg scores were obtained at the peak and corrected to TEx. CL induced greater TEx as well as number of repetitions when compared to all intensities (P<0.001). During CL, Borg/TEx, ΔSBP/TEx, ΔDBP/TEx, and [La-] were significantly lower compared with 90% load (P<0.0001). In addition, VO2, VCO2, VE, and RER were higher during CL when compared to 90 or 75%. TEx was significantly correlated with VO2 on CL (r=0.73, P<0.05). These findings support the theory that CL constitutes the intensity that can be maintained for a very long time, provoking greater metabolic and ventilatory demand and lower cardiovascular and fatigue symptoms during resistance exercise.

“…Em se tratando dos efeitos do treinamento em circuito realizado com deslocamento de cargas (circuit weight training) sobre a composição corporal, estudos demonstram que reduções de gordura corporal são observadas apenas nas situações em que o treinamento está associado a dietas hipocalóricas (Fett, Fett, & Marchini, 2009;Kerksick et al, 2009). Ao se buscar relacionar esses resultados ao TFC, lacunas são observadas não permitindo respostas conclusivas, uma vez que a instabilidade que caracteriza este tipo de treinamento e uso de sobrecargas de tipos variados (extensores) podem promover efeitos distintos sobre a composição corporal.…”

“…Sobre esse método e sua relação com a composição corporal, estudos recentes demonstram que reduções de gordura corporal são observadas apenas nas situações em que o treinamento em circuito está associado a dietas hipocalóricas (Fett et al, 2009;Kerksick et al, 2009) Dias et al (2006), por sua vez, ao compararem os efeitos de diferentes programas de exercício nos quadros clínico e funcional de mulheres com excesso de peso, constataram que as voluntárias que realizaram um treinamento combinado composto por exercícios de força em circuito e atividade aeróbia em esteira e bicicleta ergométrica apresentaram maiores níveis de redução de MGA e aumentos de MCM, quando comparadas ao grupo de mulheres que realizou treinamento de força isolado. Igualmente aos resultados do presente estudo, Dias et al (2006) não constataram reduções estatisticamente significativas de MGA no primeiro grupo de mulheres; no entanto, quando os valores são analisados na forma de percentual de gordura, a significância estatística foi observada.…”

RESUMOO presente estudo objetivou analisar os efeitos do treinamento funcional com cargas (TFC) na composição corporal de mulheres fisicamente inativas. Vinte mulheres (25.70 ± 4.20 anos) foram designadas aleatoriamente para os grupos experimental (GE, n = 10) e controle (GC, n = 10), tendo o GE realizado 12 semanas de TFC, enquanto o GC não recebeu qualquer intervenção. As variáveis antropométricas avaliadas em ambos os grupos foram: massa corporal (MC), estatura, índice de massa corporal (IMC), massa de gordura absoluta, massa corporal magra (MCM) e percentual de gordura (%G). Os testes t de Student independente e pareado foram utilizados para a comparação das médias inter e intra-grupos experimental e controle (p < .05). O GE apresentou reduções significativas nos valores de %G (p < .001), enquanto o GC aumentou seus níveis de MCM (p < .001), IMC (p < .001) e MC (p = .021). Os resultados indicaram que após de 12 semanas o TFC reduz os níveis de gordura corporal, mas não promove aumentos de MCM em mulheres fisicamente inativas. Palavras-chave: treinamento funcional, composição corporal, mulheres, estudo experimental ABSTRACTThis study aimed to analyze the effects of the functional strength training (FST) on body composition of physically inactive women. Twenty women aged between 19 and 34 years old (25.70 ± 4.20 yr.) were randomly assigned to experimental (EG, n = 10) and control group (CG, n = 10). The EG performed 12 weeks of FST, while CG did not receive any intervention. The anthropometric variables evaluated in both groups were: body mass (BM), height, body mass index (BMI), absolute fat mass (AFM), lean body mass (LBM) and fat percent (%F). The paired and independent samples t tests were used to identify modifications between and within experimental and control groups (p < .05). The EG decreased %F values (p < .001), while CG increased the LBM (p < .001), BMI (p < .001) and BM (p = .021). Results showed that after 12 weeks FST can be useful to reduce body fat mass, but it doesn't promote increases on LBM of physically inactive women.
