Objetivo: El objetivo de la presente investigación fue determinar el efecto del orden de ejecución de ejercicios contra resistencia (CR) sobre la presión arterial (PA) en reposo de jóvenes estudiantes normotensos. Método: Para el estudio se contó con la participación de 14 hombres sanos, familiarizados con el ejercicio de contra resistencia con edad promedio de 23.3 ± 1.4 años. Las condiciones experimentales fueron realizadas en orden aleatorizado, en diferentes días de trabajo y consistieron en: (1) iniciar el ejercicio CR con grupo muscular grande y terminar con pequeños (G-Peq), (2) iniciar con grupos musculares pequeño y finalizar con grandes (P-Gde) y (3), condición control .La rutina de ejercicio constó de ocho ejercicios  los cuales se trabajaron al 60% de 1 repetición máxima (RM), se realizaron 3 series de 10 repeticiones para cada ejercicio , las mediciones de presiones arteriales se tomaron antes del ejercicio, al terminar el  ejercicio y cada 10 minutos luego de terminar la rutina durante 1 hora. Resultados: En la PA sistólica se encontraron disminuciones importantes durante 30 min tanto de la condición G-Peq como de la P-Gde en comparación con el grupo control (p≤ 0.001), no obstante, la magnitud de la disminución fue mayor posterior a G-Peq (6-11 mm Hg) en comparación con P-Gde (4-10 mm Hg). Para la PA diastólica no se encontró interacción significativa (p=0.39). Conclusión. Existe efecto hipotensor posterior a ambas rutinas, sin embargo, se observó una disminución mayor de la PA sistólica al finalizar la rutina con grupos musculares grandes. Abstract. Objective: The aim of this study was to determine the effect of the order of execution of resistance training exercises (RT) on blood pressure (BP) in normotensive young students at rest. Method: 14 healthy men (mean age of 23.3 ± 1.4 years) who were familiar with resistance training participated in this study. The order of participation for the experimental conditions was randomized; the different conditions consisted in: (1) RT starting with large muscles groups and finishing with small ones (L-S), (2) RT starting with small muscles groups and ending with large ones (S-L) and (3) the control condition. RT routine consisted of eight exercises with intensity of 60% of one repetition maximum (RM). The participants performed 3 sets of 10 repetitions for each exercise. Blood pressure measurements were taken before exercise, at the end of the year, and every 10 minutes after finishing the routine for 1 hour. Results: systolic BP reduction was found for 30 min both in L-S and S-L compared with the control group (p ≤ 0.001), although the magnitude of the decrease was higher after L-S (6-11 mmHg) compared with S-L (4-10 mmHg). For diastolic BP no significant interaction was found (p=0.39). Conclusion There exists a hypotensive effect after both routines; however, there was a greater decrease of systolic BP at the end of the routine with large muscle groups.

Objetivo: Analisar o efeito agudo de diferentes métodos de musculação. Métodos: Participaram deste estudo 10 mulheres praticantes de musculação a partir de 12 meses, com idade 27,6 ± 6,5 anos. As participantes em cada sessão de treinamento utilizaram métodos de treinamento resistido, e analisaram a frequência cardíaca e a percepção subjetiva de esforço (PSE). Resultados: Os métodos Drop-Sets (DS), Repetições Forçadas (RF) e Super Lento (SL) são mais vigorosos na PSE pela prática e também promovem maior aumento na frequência cardíaca em comparação com os outros métodos de treinamento de força analisados. Ainda, observa-se que os mesmos métodos DS, RF e SL encontram-se entre 63-74% FCmáx. Conclusão: Os métodos de treinamento resistido Repetições Forçadas e Super Lento são mais eficientes caso o objetivo do cliente seja o trabalho na zona aeróbia.Palavras-chave: treinamento de resistência, exercício, força muscular. Palavra-Chave: Treinamento de Resistência. Exercício. Força Muscular. ABSTRACT Objective: To analyze the acute effect of different methods of bodybuilding. Methods: Ten women practicing bodybuilding participated in this study from 12 months, with ages ranging from 27.6±6.5 years. The participants in each training session used resistance training methods and analyzed the heart rate and subjective perception of effort (SPE). Results: The Drop-Sets (DS), Forced Repetitions (FR) and Super Slow Strength (SS) methods are more vigorous in SPE by practice and also promote a greater increase in heart rate compared to other methods of strength training analyzed. Furthermore, the same DS, FR and SL methods are found to be between 63-74% HRmax. Conclusion: Resisted Forced and Super Slow Strength resistance training methods are more effective if the client's goal is work in the aerobic zone. Keywords: Resistance Training. Exercise. Muscle Strength.

The effects of androgen precursors, combined with herbal extracts designed to enhance testosterone formation and reduce conversion of androgens to estrogens was studied in young men. Subjects performed 3 days of resistance training per week for 8 weeks. Each day during Weeks 1,2,4,5,7, and 8, subjects consumed either placebo (PL; n = 10) or a supplement (ANDRO-6; n = 10), which contained daily doses of 300 mg androstenedione, 150 mg DHEA, 750 mg Tribulus terrestris, 625 mg Chrysin, 300 mg Indole-3-carbinol, and 540 mg Saw palmetto. Serum androstenedione concentrations were higher in ANDRO-6 after 2,5, and 8 weeks (p < .05), while serum concentrations of free and total testosterone were unchanged in both groups. Serum estradiol was elevated at Weeks 2, 5, and 8 in ANDRO-6 (p < .05), and serum estrone was elevated at Weeks 5 and 8 (p < .05). Muscle strength increased (p < .05) similarly from Weeks 0 to 4, and again from Weeks 4 to 8 in both treatment groups. The acute effect of one third of the daily dose, of ANDRO-6 and PL was studied in 10 men (23±4years). Serum androstenedione concentrations were elevated (p < .05) in ANDRO-6 from 150 to 360 min after ingestion, while serum free or total testosterone concentrations were unchanged. These data provide evidence that the addition of these herbal extracts to androstenedione does not result in increased serum testosterone concentrations, reduce the estrogenic effect of androstenedione, and does not augment the adaptations to resistance training.
