Comportamento subagudo da pressão arterial após o treinamento de força em hipertensos controlados

Several studies have shown a benefic effect of the power exercise on the reduction in the post-exercise blood pressure (BP), but there are insufficient researches involving hypertensive individuals. Thus, the present study has as main purpose to compare the BP responses on medicated hypertensive individuals after two sessions of power exercise with different training volumes. For this, it was studied 20 individuals of both genders (61 ± 12 years) with their hypertension controlled through medication, and who participated in an exercise program, but with no experience in power training. The study was performed in three non-consecutive days. First, it was determined ten maximal repetition load in each exercise of the sequence (straight supine, horizontal leg-press, stand-up-rowing, and triceps curl). In the remaining days, the same exercises were performed in one (SER1) or three (SER3) series. The BP measurement was performed through the auscultatory method in the pre-exercise period, immediately after each session, and within 60 minutes after ending the exercises. The repeated ANOVA measurements has identified in both sessions that the systolic (SBP), and diastolic blood pressure (DBP) values measured right after ending the exercises were higher (p < 0.05) than in the pre-exercise. The 60 minutes follow-up after the SER1 showed a reduction in the SBP only in the 40th minute, while it was found no reduction in the DBP. After the SER3, it was noted a fall in the SBP levels that lasted for the whole monitoring period. As to the DBP, it was found reductions in the 30th and 50th postexercise minute. It can be concluded that a power training session can promote reductions in the levels of the SBP on medicated hypertensive individuals, and it seems to be necessary a higher training volume for that effect to occur.ABSTRACTSubacute behavior of the blood pressure after power trainingin controlled hypertensive individuals Several studies have shown a benefic effect of the power exer-cise on the reduction in the post-exercise blood pressure (BP), butthere are insufficient researches involving hypertensive individu-als.

Influência da frequência semanal do treinamento de força sobre o desempenho funcional em idosas

Introducion: Aging occur declines structural and functional that can to affect physical independence. Objective: Verify the influence of weekly frequency of Strength Training (ST) on functional performance in older women. Methods: 21 older womenwere divided in two groups that trained in one (G1: n=11) or two times a week (G2: n=10). The ST applied was in format of circuit that consisted of three turns with interval of 30 seconds in between exercises and repetitions between eight and 10. Results: Results showed improvement over pre-training in all tests in both groups (p 0.05). Conclusion: ST is capable of promoting improvements in functional performance regardless of training frequency.

Avaliação da força muscular extensora do tronco: influência do gênero e do estado de treinamento

Introduction: Trunk extensor muscles strength is important for low back prevention pain. However, it is not established whether a non-specific training for this region is sufficient. Objective: Compare trunk muscle extensors strength of the sedentary subjects and resistance training practitioners (RT) who did not perform any specific exercises for this region. Methods: It was recruited 105 healthy subjects (61 men and 44 women) with age between 18 and 44 years who were divided into groups trained and sedentary. Experienced in RT trained squat and military press. The remaining subjects had no experience in RT. Results: There were differences in strength between trained and sedentary men (p = 0.002) and gender (p = 0.0003), there was no difference between women trained and sedentary (p≥0.05). Conclusion: RT non specific increase the strength of the lumbar region in men. However, it is not enough in the female public.

A Description and Comparison of Cardiorespiratory Fitness Measures in Relation to Pitching Performance Among Professional Baseball Pitchers

The purpose of this study is to provide descriptive and comparative information regarding the cardiorespiratory fitness of professional baseball pitchers. Twenty-four (n = 24) major league (ML) baseball pitchers (starters n = 14; relievers n = 10) over seven seasons (2007–2013) were evaluated. A modified Bruce protocol and the CardioCoach™ CO2 metabolic analyzer were used to estimate VO2 max and anaerobic threshold (AT) at the beginning of each season. Performance data from each season was utilized to draw inference about pitching performance. One-way Analysis of Variance (ANOVA) was used to compare Starting (S) and Relief (R) pitchers above/below the group mean for VO2 max and AT. Pearson product moment correlations were also used to examine relationships between cardiorespiratory fitness and performance. Significant differences in performance were discovered between S pitchers above/below the overall group mean for VO2 max. (p ≤ 0.05) and for AT in Walks plus Hits per Inning Pitched (WHIP) (p ≤ 0.05) and Earned Run Average (ERA) (p ≤ 0.05). Significant relationships between VO2 max and Walks per 9 Innings (BB/9) (p ≤ 0.05), Home Runs per 9 innings (HR/9) (p ≤ 0.05), Wins (W) (p ≤ 0.05), Fielding Independent Pitching (FIP) (p ≤ 0.01), Strikeouts (K) (p ≤ 0.01), Hits per 9 innings (H/9) (p ≤ 0.01), Strikeouts per 9 innings (K/9) (p ≤ 0.01), ERA (p ≤ 0.01), and WHIP (p ≤ 0.01). Low, but significant, correlations were discovered between AT and WHIP (p ≤ 0.05) and ERA (≤0.05). CONCLUSION: Higher aerobic capacity appears to be more influential for S than R pitchers. Strength and conditioning practitioners should ensure that pitchers, especially S pitchers at the ML level, perform sufficient and appropriate endurance training to support pitching performance.

BASES CIENTÍFICAS DOS MÉTODOS E SISTEMAS DE TREINAMENTO DE FORÇA

Das inumeras possibilidades manipulacao das variaveis metodologicas de prescricao originaram os variados metodos ou sistemas de treinamento de forca (TF). O objetivo deste estudo foi realizar uma revisao de literatura sobre os metodos e sistemas do TF analisados em estudos originais, suas metodologias e aplicacoes praticas. Com base na analise de 20 estudos originais observamos que o metodo crescente pode ser utilizado como progressao de cargas leves para pesadas como forma de “aquecimento” para a utilizacao de cargas elevadas. Ja o metodo decrescente justifica-se pela necessidade de diminuir a carga devido a fadiga quando um intervalo entre series insuficiente e utilizado. Assim como no metodo decrescente, as reducoes na carga no metodo dropset tem a finalidade de contornar a fadiga, adequando o esforco as possibilidades momentâneas do musculo e, com isso, mantendo um trabalho relativamente intenso por mais tempo. O treinamento em circuito resulta em maior gasto calorico e consumo de oxigenio pos-exercicio do que o TF tradicional e pode resultar em ganhos similares na forca maxima e massa magra. O metodo agonista-antagonista resulta em aumento no gasto calorico quando comparado a um programa convencional e parece ser tao eficiente quanto metodo alternado por segmento para a promocao de ganhos em flexibilidade e forca. Mesmo resultando em reducao da atividade eletromiografica durante o exercicio principal, o metodo pre-exaustao promove a realizacao de um maior volume total de treinamento quando comparada a ordem inversa. E por fim, o treinamento excentrico (sistema negativo) resulta em ganhos elevados na forca e hipertrofia. Em conclusao os metodos e sistemas do TF devem ser prescritos com atencao e cautela para garantir a seguranca, qualidade e continuidade dos resultados.
