Comparação entre diferentes modelos de periodização sobre a força e espessura muscular em uma sequência dos menores para os maiores grupamentos musculares

Abstract

Introduction: Studies comparing periodization models in sequences that begin with small muscle group and progressed toward large muscle group in untrained subjects in resistance training are scarce. Objective: The purpose of this study was to compare the effects of ondulatory periodization and linear periodization models on maximum strength and muscular hypertrophy in a muscle group increasing exercise sequence. Methods: Twenty-nine men with no experience in RT were randomly assigned into three groups: ondulatory periodization (OP, n = 10), linear periodization (LP, n = 13), and control group (CG, n = 9). The individuals performed 1RM tests in four exercises: biceps curl (BC), triceps extension (TE), lat pull down (LPD) and bench press (BP) and evaluations of maximum voluntary isometric contraction (MVIC), muscle thickness of elbow flexors (EF) and elbow extensors (EE) before and after the 12 weeks of training were carried out. The OP group varied in volume and intensity on a daily basis, while LP group varied every four weeks. The CG did not perform ST. A two-way ANOVA with repeated measures and the effect size (ES) were used to analyze muscle thickness, 1RM load improvement in each of the four exercises and the MVIC between groups. Results: The major findings of this study were: 1) OP showed major ES for 1RM of BC and TE and for muscle thickness of EF and EE when compared with LP.3) The ES data did not show significant differences for BP and LPD which finished the training session. Conclusions: We conclude that both periodization models were efficient at improving strength gains and muscular growth. However, ES data show that OP promotes major gains in strength for exercises that are positioned at the beginning of the session and hypertrophy.

Effect of strength training on regional hypertrophy of the elbow flexor muscles

“…The 1‐RM test consisted of elbow flexion performed on a Scott Preacher bench. The protocol was previously described by Simão et al To minimize errors during the test, strategies similar to those used in the study by Spineti et al were used. After 48 h, a second 1‐RM test session was performed to determine the reliability of the measurements …”

“…With MRI, muscle hypertrophy induced by strength training can be assessed in terms of changes in CSA of the medial muscle region, the average axial slices along the muscles, or the muscle volume . Analyses of hypertrophy in the medial region of trained muscles have been reported commonly; however, this method may not accurately reflect the hypertrophy of all muscle regions .…”

Correlação Entre a Medida Antropométrica De Coxa E a Força Em 10 Repetições Máximas

“…Embora existam, na literatura, estudos que associam ganhos de força com o ganho de hipertrofia muscular 13,14 , há relato na literatura em que os ganhos de força não foram acompanhados por respostas hipertróficas 15 .…”

Efeito do treinamento resistido com diferentes cargas e posicionamentos de segmentos corporais na força, hipertrofia, potência e resistência muscular e sinal eletromiográfico em homens treinados

“…Embora a manipulação das variáveis de treinamento possa parecer simples à primeira vista, a complexidade surge pois, a mudança em uma variável pode resultar em uma alteração inadvertida subsequente de outras variáveis (MARTORELLI et al, 2021). A manipulação de todas as variáveis metodológicas do treinamento físico, divididas em fases lógicas, que tem como objetivo realizar ajustes específicos para o aumento do desempenho físico e prevenir o excesso de treinamento, pode ser chamada de periodização (SPINETTI et al, 2013). De acordo com Haff e Triplett (NSCA, 2016), a periodização permite a programação sistemática, sequencial e integrativa de sessões de treinamento para maximizar adaptações fisiológicas específicas que sustentam os resultados de desempenho.…”
