    ABSTRACT: The aim of this study was to examine acute hormonal responses after different sequences of an upper-body resistance-exercise session. Twenty men completed 2 sessions (3 sets; 70% 1-repetition maximum; 2 min passive rest between sets) of the same exercises in opposite sequences (larger to smaller vs. smaller to larger muscle-group exercises). Total testosterone (TT), free testosterone (FT), testosterone/cortisol (T/C) ratio, sex-hormone-binding globulin (SHBG), growth hormone (GH), and cortisol (C) concentrations were measured before and immediately after each sequence. The results indicate that the GH concentration increased after both sessions, but the increase was significantly greater (p < 0.05) after the sequence in which larger muscle-group exercises were performed prior to the smaller muscle-group exercises. No differences were observed between sessions for TT, FT, SHBG, C, or the T/C ratio at baseline or immediately after resistance exercise. These results indicate that performing larger muscle-group exercises first in an upper-body resistance-exercise session leads to a significantly greater GH response. This may have been due to the significantly greater exercise volume accomplished. In summary, the findings of this investigation support the common prescriptive recommendation to perform larger-muscle group exercises first during a resistance-exercise session.

Résumé : Cette étude se propose d'analyser les réponses immédiates des hormones suscitées par diverses séquences d'exercices contre résistance du haut du corps. Vingt hommes participent à deux séances comprenant trois séries d'exercices réalisés à 70% 1-RM; chaque séance, intercalée de 2 min de repos passif, est constituée des mêmes exercices réalisés, mais selon des séquences inversées (exercices des grosses masses musculaires suivis des exercices des petites masses musculaires vs exercices des petites masses musculaires suivis des exercices des grosses masses musculaires). Avant et immédiatement après chacune des séances, on évalue la concentration des variables suivantes : testostérone totale (TT), testostérone libre (FT), ratio testostérone/ cortisol (T/C), globuline spécifique (SHBG), hormone de croissance (GH) et cortisol (C). D'après les observations, la concentration de GH augmente à la suite de chacune des séances, mais l'augmentation est significativement plus grande (p ≤ 0,05) à la suite de la séance commençant par les exercices des grosses masses musculaires suivis des exercices des petites masses musculaires. On n'observe aucune différence en ce qui concerne TT, FT, SHBG, C et T/C avant et après chacune des séances d'exercices contre résistance. D'après ces observations, la réalisation des exercices contre résistance du haut du corps sollicitant des grosses masses musculaires suscite notamment une plus grande réponse significative de la GH. Cette plus grande réponse significative de la GH suscitée par des exercices des grosses masses musculaires est probablement due au plus important volume d'exercices réalisés. Ces observations appuient la recommandation courante d'effectuer en premier lieu les exercices des grosses masses musculaires au cours d'une séance d'exercices contre résistance.

    ABSTRACT: Many studies have used the heart rate deflection points (HRDP) during incremental exercise tests, because of their strong correlation with the anaerobic threshold (AT). The aim of this study was to evaluate the profile of the heart rate deflection points identified by a computerized method and compare it to ventilatory and lactate thresholds. Twenty-four professional soccer players (age, 22 ± 5 yr; body mass, 74 ± 7 kg; height 177 ± 7 cm) volunteered for the study. Subjects completed a Bruce-protocol incremental treadmill exercise test to volitional fatigue. Heart rate (HR) and respired gases were recorded continuously at ≥ 1 Hz during exercise testing. Subsequently, the time course of the HR was fit by a computer algorithm and a set of lines yielding the lowest pooled residual sum of squares was chosen as the best fit. This procedure defined two heart rate deflection points (HRDP1 and 2). The HR break points averaged 43.9 ± 5.9 % and 89.7 ± 7.5 % of &OV0622;O2 peak. HRDP1 showed poor correlation with VT (r =.50), but HRDP2 was highly correlated with the respiratory compensation point (RC) (r = .98). Neither HRDP1 nor HRDP2 was correlated with LT1 (at &OV0622;O2= 2.26 ± 0.72 L/min;r = .26) or LT2 (2.79 ± 0.59 L/min;r = .49) respectively. LT1 and LT2 also were not well correlated with VT (2.93 ± 0.68 L/min r = .20) or RC (3.82 ± 0.60 L/min r = .58), respectively. Although the HR deflection points were not correlated with LT, HRDP2 could be identified in every subject and was strongly correlated with RC, consistent with a relationship to cardiorespiratory fatigue and endurance performance.

    ABSTRACT: The purpose of this study was to compare the postexercise hypotensive response after different rest intervals between sets (1 and 2 minutes) in normotense older men. Seventeen older men (67.6 ± 2.2 years) with at least 1 year of strength training experience participated. After determination of 10 repetition maximum (10RM) loads for exercises, subjects performed 2 different strength training sessions. On the first day, volunteers performed 3 sets of 10 repetitions per exercise at 70% 10RM, with 1 or 2 minutes' rest interval between sets depending on random assignment. On the second day, the procedures were similar but with the other rest interval. There was no difference in systolic and diastolic blood pressure between rest intervals at any time point measure. Before 1- and 2-minute sessions, the systolic blood pressure values were 122.7 ± 6.0 and 123.2 ± 3.7 mm Hg, and diastolic blood pressure values were 80.5 ± 5.6 and 82.0 ± 3.7 mm Hg, respectively. Both 1 and 2 minute sessions still presented reduced values for systolic blood pressure after 60 minutes (102.9 ± 6.9 and 106.7 ± 5.4 mm Hg, respectively), while the diastolic blood pressure presented significant reductions for 50 minutes after a 1 minute session (12.1 to 5.6 mm Hg) and for 60 minutes after the 2 minute session (13.3 to 6.5 mm Hg). Additionally, the systolic and diastolic blood pressure effect size data demonstrated higher magnitudes at all time point measures after the 2-minute rest sessions. These results suggest a poststrength training hypotensive response for both training sessions in normotense older men, with higher magnitudes for the 2-minute rest session. Our findings suggest a potentially positive health benefit of strength training.

    ABSTRACT: 1. The aim of the present study was to investigate the cardiovascular effects of anabolic androgenic steroid (AAS) abuse by comparing the electrocardiographic parameters before and after submaximal exercise between AAS users and non-AAS users. 2. A total of 22 men who regularly engaged in both resistance and aerobic exercise at fitness academies volunteered for the study (control group: n = 11, age 25 ± 4 years; AAS group: n = 11, age 27 ± 5 years). All subjects were submitted to submaximal exercise testing using an Astrand-Rhyming protocol. Heart rate and electrocardiography parameters were measured at rest and at the third minute of the post-exercise recovery time. 3. AAS users presented higher QTc and QTd at rest (10% and 55%, respectively) and at the post-exercise period (17% and 43%, respectively), compared with control subjects. The maximal and minimum QTc interval of the AAS group was significantly prolonged at the post-exercise period (12% and 15%, respectively). The haemodynamic parameters were similar in both groups (P > 0.05). The AAS group showed a lower heart rate recovery at the first minute after the test (P = 0.0001), and a higher exertion score (P < 0.0001) at a lower workload, compared with the control group. 4. Our results show that the QTc interval and dispersion are increased in individuals who abuse AAS, suggesting the presence of ventricular repolarization abnormalities that could potentially increase the risk of cardiac arrhythmias and sudden cardiac death.

    ABSTRACT: The purpose of this study was to investigate the cardiovascular effects of anabolic androgenic steroid (AAS) use, specifically the hemodynamic response, during maximal treadmill exercise testing by comparing the exercise response between users of AAS (U-AAS) and non-AAS users (N-AAS). Twenty-four men (n=12; 29+/-3.4 years and n=12; 29.5+/-8.2 years for the U-AAS and N-AAS groups, respectively) with regular participation in both resistance (mean=6 d.wk) and aerobic exercise (mean=2 d.wk) volunteered for the study. Both groups of subjects completed a ramp-protocol maximal treadmill exercise test to volitional fatigue. Several hemodynamic and metabolic measures were obtained before, during, and after testing. The results demonstrate for the first time that chronic administration of high doses of AAS (355.4+/-59.47 mg.wk) lead to hemodynamic and metabolic response impairment. In conclusion, the chronotropic significant incompetence in the current study was reflected by an exaggerated hemodynamic response to exercise. Furthermore, the findings suggest that nonusers of AAS showed increases in VO2max when compared to the AAS group. Therefore, this study provides a contraindication to AAS use, especially in those at increased risk of cardiovascular events.

    ABSTRACT: MAIOR, A. S.; SIMÃO, R.; SALLES, B. F.; MIRANDA, H.; COSTA, P. B. Neuromuscular activity during thesquat exercise on an unstable platform. Brazilian Journal Biomotricity, v. 3, n. 2, p. 121-129, 2009. Thepurpose of this study was to compare the muscular activity of the quadriceps muscles [vastus lateralis (VL),vastus medialis (VM) and rectus femoris (RF)] through surface electromyography (EMG) during the squatexercise with and without the use of an unstable platform (UP). Twenty males (25 ± 3 yrs; 180 ± 5.2 cm; 80 ±3.2 kg; 24.2 ± 1.6 Kg.m-2) with at least 12 months of experience in resistance training volunteered for thestudy. Following a specific warm up of two sets of fifteen repetitions (light and moderate load), EMGmeasurements was obtained during the two conditions: maximum voluntary contraction (MVC) on a stablesurface and another MVC on an unstable platform. Three-minute rest intervals between the conditions wereallowed. The Wilcoxon test revealed significantly greater (p < 0.05) muscle activation of the quadricepsmuscles during the squat exercise on the UP (VL = 21%; RF= 18%; VM = 16%). The results of this studyrevealed the UP may be incorporated in some periods of resistance training to increase the activity of thequadriceps muscle.

    ABSTRACT: The aims of this study were to valuate and to compare the weight moved during the execution of the 1 RM test using two different methodologies: with and without visual privation. The sample was composed of twelve men with age 29 ± 7.9 years, weight 79.1± 9.6 kg, height 175 ± 6.2 cm and BMI 25.8 ± 2.7 Kg/m², divided into 2 sessions, for the following exercises: Bench press (BP), Leg-press (LP) and Lat pull down (LPD). The study protocol was broken down as follows: 1st Day – Measurements taken of body mass and height. The 1RM test was then applied without visual privation; 2nd Day - retest of 1RM to check weight reliability; 3rd Day - Application of the test of 1RM with visual privation; 4th Day - retest of 1RM to check weight reliability. Therefore, for each methodology, the individuals were subjected to two sessions of 1RM tests in order to achieve better intratest reliability (r=0.98, r=0.95 and r=0.94, for LP, BP and LPD respectively). Applying Student’s t test to the results demonstrated a signifi cant increase in muscle strength when the 1RM test was performed with visual privation, in relation to the test without visual privation, for bench press (5.37% - p <0.0001), leg press (8.25% - p <0.0001) and Lat pull down (5,12% - p <0,0001). Intertest correlation was high with and without visual privation (Leg press - r = 0.98, bench press - r = 0.98, Lat pull down - r = 0.94) .In conclusion, the application of the 1RM test with visual privation was shown to be effective because it prevents the subject from seeing the test weight, and consequently underestimate their own performance and possible increase cognitive self-effectiveness. RESUMO O objetivo deste estudo foi avaliar e comparar o valor de carga deslocado durante a execução do teste 1RM em duas situações: com e sem privação visual. A amostra foi composta de doze homens (idade 29 ± 7,9 anos; peso 79,1 ± 9,6 kg; altura 175 ± 6,2 cm; IMC 25,8 ± 2,7 Kg/m²) divididos em 2 sessões para os exercícios: Supino horizontal (SH), Leg-press 45º (LP) e puxada de frente (PF). A metodologia consistiu na validação da carga máxima entre 3 a 5 tentativas. A cada nova tentativa realizava-se adição de incrementos progressivos, sendo dado um intervalo de 3 a 5 minutos entre cada tentativa. O protocolo do estudo dividiu-se em: 1º Dia - Medida da massa corporal e estatura. Logo após aplicou-se o teste de 1RM sem privação visual para os exercícios selecionados; 2º Dia – teste de 1RM para confi abilidade de carga; 3º Dia - Aplicação do teste de 1RM com privação visual; 4º Dia - teste de 1RM para confi abilidade de carga. Assim, a confiabilidade intratestes mostrou-se alta (r=0,98, r=0,95 e r=0,94 para LP, SH, e PF, respectivamente). A partir da amostra dos dados pelo test T student, pareado, foi verifi cado aumento signifi cativo da força muscular para os testes de 1RM com privação visual em relação ao teste sem privação visual nos exercícios supino horizontal (5,37% - p<0,0001), leg press 45° (8,25% - p<0,0001) e puxada pela frente (5,12% - p<0,0001) (Tabela 1). Os resultados mostraram alta correlação intertestes com e sem privação visual (LP - r= 0,98, SP - r = 0,98, PF – r= 0,94). A conclusão mostrou a efetividade do teste de 1RM com privação visual pelo fato de evitar que o sujeito visualize a carga de teste, conseqüentemente, subestime o seu desempenho e, hipoteticamente, aumente sua auto-efi cácia cognitiva.

    ABSTRACT: O objetivo do estudo foi verificar a influência de três diferentes intervalos de recuperação no desempenho da força. Partici­param do experimento 10 homens (27,5 ± 7,72 anos; 77,43 ± 13,27 kg; 174 ± 5 cm) treinados. Na primeira visita, os indivíduos executaram o teste de 10RM, e após 48h foram reavaliados. A aplicação do teste 10RM obedeceu a seguinte ordem: supino horizontal (SH), cadeira extensora (CE) e rosca bíceps (RB). Posteriormente, os indivíduos foram testados em apenas um intervalo nas três séries em cada dia. Para o tratamento dos dados utilizou-se uma ANOVA de duas entradas para medidas repetidas em associação ao teste post-hoc de Tukey. Comparando o número de repetições dos três exercícios, todas as séries comparadas à série anterior apresentaram redução no número de repetições (p<0,05). Os dados desse estudo sugerem que intervalos de recuperação de 45, 90 e 120 s, apre­sentam redução do número de repetições máximas com a evolução das séries, em todos os intervalos de recuperação estudados.

    ABSTRACT: São escassos na literatura estudos que investigaram a influência de diferentes intervalos de recuperação em um treinamento aplicado em longo prazo. O objetivo do presente estudo foi verificar a influência de dois diferentes intervalos de recuperação entre séries, durante quatro semanas de treinamento. Participaram do estudo 26 homens (22,5±2,1 anos; 180,5±4,3 cm; 83,4±5,3 kg), divididos igualmente em dois grupos. Um dos grupos realizou quatro séries de 8-12RM nos exercícios supino horizontal, hack machine, rosca bíceps, leg-press 45o, puxada pela frente no pulley alto, abdominal flexão parcial (15-20RM) e tríceps no pulley, com 1 minuto de intervalo de recuperação entre as séries. O outro grupo realizou o mesmo treinamento, sendo que o intervalo entre as séries foi de 3 minutos. Foram realizados testes de 10RM nos exercícios supino horizontal (SH) e rosca bíceps (RB), antes do treinamento e após quatro semanas. A ANOVA de uma entrada com medidas repetidas, seguida do teste post-hoc de Tukey, identificou aumento da carga de 10RM entre o pré-treinamento e a quarta semana para o exercício RB, mas não para o SH. Entretanto, não foram observadas diferenças significativas quando comparados os intervalos de recuperação em nenhum dos exercícios. Concluiu-se que o intervalo de recuperação adotado em um treinamento de quatro semanas não influenciou a força nos testes de 10RM. Mas considerando as limitações deste estudo, sugere-se a realização de experimentos futuros com maiores tempos de acompanhamento e amostras com vários estados de treinamento.

    ABSTRACT: O objetivo do estudo foi verificar a influência de dois diferentes intervalos de recuperação nos exercícios resistidos (ER) e percepção subjetiva do esforço (PSE). Participaram do experimento 14 voluntários do sexo masculino (27,64 anos ± 2,73; 80,21 kg ± 9,77; 179,85 cm ± 6,59), praticantes de ER há pelo menos seis meses ininterruptos. Na primeira visita, os indivíduos executaram o teste de 10RM, e após 48h foram reavaliados. A aplicação do teste 10RM obedeceu à seguinte ordem: supino horizontal e voador frontal. Posteriormente, os indivíduos foram testados em apenas um intervalo nas três séries em cada dia, sempre na mesma ordem e a PSE foi avaliada ao final da seqüência. Para o tratamento dos dados utilizou-se uma ANOVA de duas entradas para medidas repetidas em associação ao teste post-hoc de Tukey. Para verificação da PSE utilizou-se o teste de Wilcoxon. Comparando o número de repetições nos dois exercícios, todas as séries comparadas à série anterior apresentaram redução no número de repetições, entretanto não se verificaram alterações na PSE devido ao intervalo adotado. Os dados desse estudo sugerem que intervalos de recuperação de 2 ou 5 minutos, apresentam redução do número de repetições máximas com a evolução das séries, mesmo sem significância em todos os casos. A PSE não sofreu alteração devido ao intervalo adotado.

    ABSTRACT: This study examined the performance effects of exercise order during a resistance-training session composed of only upper-body exercises. The 10 repetition maximum of 14 men and 4 women with at least 6 months of previous weight-training experience was determined for 5 upper-body exercises. Each subject then completed 2 training sessions separated by 48 hours in a counterbalanced crossover design. One session began with exercises of the large-muscle group and progressed to exercises of the small-muscle group (sequence A), whereas the other session was performed with the opposite exercise sequence (sequence B). The exercise order for sequence A was free-weight bench press (BP), machine lat pull-down (LPD), seated machine shoulder press (SP), standing free-weight biceps curl (BC) with a straight bar, and seated machine triceps extension (TE). The exercise order for sequence B was TE, BC, SP, LPD, and BP. During both sequences, 3 sets of each exercise were performed to concentric failure, with 2-minute recovery intervals between sets and exercises. Performing exercises of both the large- and the small-muscle groups at the end of an exercise sequence resulted in significantly fewer repetitions in the 3 sets of an exercise. This decrease in the number of repetitions performed was especially apparent in the third set when an exercise was performed last in an exercise sequence.

    ABSTRACT: Teoricamente, existe a necessidade da realização de um aquecimento antes dos exercícios resistidos (ER), porém pouco se sabe sobre seus diferentes protocolos e sua influência antes da realização dos ER. O objetivo deste estudo foi verificar a influência do aquecimento específico (Ae), aquecimento de flexibilidade (Af) e aquecimento aeróbico (Ar), antes do desenvolvimento de cargas máximas, em 15 indivíduos (idade 22 ± 3) aparentemente saudáveis. Foi realizado o teste de uma repetição máxima (1RM) no exercício de leg-press, e comparou-se a resposta dos diferentes tipos de aquecimentos por meio de ANOVA, com verificação post-hoc de Tukey (p<0,05). Os testes nos permitiram ordenar os resultados da carga máxima da seguinte forma: Ae = 134,5 ± 26,6; Ar = 131,3 ± 27,4; Af = 129,9 ± 28,3. Em conclusão, em 60% dos indivíduos, o Ae foi o protocolo que possibilitou a maior mobilização de carga, mesmo com tal predominância, a comparação não foi significante quando comparadas às três variáveis na ANOVA. Em 20%, o Ar foi o protocolo de maior eficiência e o Af foi responsável pelo melhor desempenho em apenas 6,6% dos avaliados. Deve-se ainda ressaltar que a não diferenciação de carga ocorreu em 13,4% dos avaliados, estes tendo no mínimo duas respostas idênticas em valor.

    ABSTRACT: Background: Due to assorted variables related to resistance training, its effects on autonomic cardiac control are still unknown. Objective: To ascertain the acute effects of different strength training intensities − 6 and 12 maximum repetitions (6MR and 12MR) − on the autonomic cardiac system during six resistance exercises. Methods: Ten male volunteers (age: 27.5±5.6 years; weight: 81.6±26.9kg; height: 177.6±11.8cm; BMI: 24.45±6.7kg/m²) took part in the study, performing six exercises (6MR and 12MR). Heart rate variability (HRV) was obtained from the RR intervals. The following time domain algorithms were calculated: mean RR interval; variation in mean RR interval (VarRR); NN50; pNN50; RMSSD. For the frequency domain, the following low-frequency (LF: 0.04-0.15Hz) and high-frequency (HF: 0.15-0.40Hz) capacity spectra were analyzed, in addition to the LF/HF ratio and total capacity. Results: There were no statistical differences between the groups (6MR and 12MR) in either of t h e H RV d o m a i n s . H o w e v e r, t h e i n t r a - g ro u p comparison (pre vs post) presented a significant difference in the 6MR HRV only for the frequency domain variables (HF, unLF, unHF and LF/HF), w h i l e t h e 1 2 M R t r a i n i n g p ro t o c o l p re s e n t e d differences in the both the time (iRR, NN50, pNN50, RMSSD) and frequency (total capacity, LF, unLF; HF, unHF) domains.

    ABSTRACT: The aim of the study was to verify the test of 10 maximum repetitions (10RM) in the straight chest press exercise in the machine being used different types of warm up. Twenty two individuals of the men gender and divided in two groups had been selected, group with previous heating of flexibility (GF) (n=11), and group specific warm up (GS) (n=11). The individuals of the sample had been submitted to the 10RM test, in two days. In the first day, one equally became fulfilled the test of 10RM for both the groups, following the traditional model of the test. In as the day, GS carried through the test of 10RM with heating of two series with 15 repetitions 55% of the 10RM load. The GF preceded the test of 10RM with the heating through exercises of flexibility for the static method, with two series of 20 seconds of duration for each position, after to reach the pain threshold. It was kept an interval 20 seconds of a series for another one. We conclude that no significant differences through the test t-Student (p>0.05) in the performance of the test of 10RM in the straight chest press exercise through the specific warm up, the same not being observed when the 10RM test was preceded by exercises of flexibility (p

    ABSTRACT: O objetivo deste estudo foi verificar o grau de satisfação de pacientes submetidos à reconstrução do ligamento cruzado anterior (LCA), com o terço médio do tendão patelar autógeno, seguido de um programa de reabilitação neuromuscular. Participaram do estudo 22 pacientes (20 homens e 2 mulheres), com idade média de 34 (± 8) anos, que realizaram tratamento no período entre março/2002 a março/2003. Um questionário fez o levantamento dos sintomas residuais, da capacidade de executar atividades funcionais e da participação em atividades esportivas antes e após o tratamento. Foi utilizada uma escala analógica de 0 a 10 para avaliação do grau de satisfação dos pacientes com o tratamento realizado. Os principais sintomas apresentados após o tratamento foram fraqueza muscular no membro envolvido (59%) e limitação articular (18,2%). Durante as atividades de vida diária, as dificuldades mais freqüentes foram ajoelhar ou agachar (22,7%) e dificuldade para subir escadas (22,7%). Outros 22,7% não relataram qualquer sintoma pós-tratamento. O futebol apareceu como a principal causa de lesão do LCA (81,8% dos casos). Dos 18 pacientes que praticavam futebol como atividade de lazer, somente oito (44%) retornaram a praticá-lo após o tratamento. Concluiu-se que a maioria dos pacientes (68%) submetida à reconstrução de LCA seguida de reabilitação apresenta um índice de satisfação excelente ou bom no período mínimo de seis meses após o tratamento, mas não retorna completamente ao estado pré-lesão.
