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: ondulat… Show more
“…The training methodologies were elaborated with a view to improving various physical capacities. It is possible to affirm that a longer period of training, above eight weeks, could cause significant differences in this variable, since this same fact was found in a similar study (Spineti et al, 2013).…”
The aim of this study was to compare the effect of eight weeks of traditional physical training (TPT) and military-specific physical training (MSPT) on the physical and operational performance of infantry cadets of the Brazilian Air Force (BAF). This study consisted of 27 male cadets (22.8±1.6 years, 76.0±9.2 kg, 1.77±0.05 m) stratified according to initial levels of physical fitness and randomly allocated in TPT (n= 13) or MSPT (n= 14) groups. The TPT group performed the basic military physical training provided for the military and the MSPT group conducted specific operational training. The variables were analyzed through two evaluations at the beginning and end of the eight-week training protocol. Anthropometric evaluations, physical fitness, and military operational physical tests were performed. Internal training load was determined through session rating of perceived exertion. Two-way (group and time) analysis of variance was used to compare groups and periods of training. Bonferroni test was used as a post-hoc when necessary. The effect sizes were presented by partial eta squared (ηp²) and Cohen dz. No group and time interaction was found for any variable. Regarding the time effect, there was a decrease in both groups in the anthropometric variables. The variables that increased over time for both groups were push-up and sit-up repetitions in 1 min, aerobic power, and squat jump height, whereas time in the military operational physical test decreased. Regarding the internal training load, no interaction between the group and period was observed. Therefore, both TPT and MSPT groups were effective in improving the physical and operational performance of military personnel after eight weeks of training.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/soc/0036/a.php" alt="Hit counter" /></p>

“…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 .…”
Muscle hypertrophy may be assessed using only the medial CSA. We should not expect different degrees of hypertrophy among the regions of the elbow flexor muscles. Muscle Nerve 54: 750-755, 2016.
“…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 .…”
Verificar se existe correlação entre a medida antropométrica de coxa com a força muscular em 10 repetições máximas (10RM) no exercício de cadeira extensora. Foram selecionadas 16 mulheres treinadas (idade: 20 ± 6 anos) para a mensuração dos dados antropométricos e avaliação da força de 10RM. Os avaliados foram orientados de forma padronizada para garantir maior uniformidade dos valores. Foram realizadas três tentativas a fim de se achar a carga de 10RM. Toda a coleta de dados foi realizada em um dia. Após a coleta dos dados, foram realizados os trabalhos estatísticos, os quais possibilitaram ver se os dados eram paramétricos ou não paramétricos. Com os resultados pode-se observar que não ocorreu correlação entre os valores de perímetro de coxa e força de 10RM, visto o valor r = -0,2271. Isso revela uma correlação moderada negativa de acordo com a tabela de correlação de Pearson. Pode-se concluir que não ocorreu correlação entre a perimetria de coxa e a força de 10RM, ou seja, a força na amostra ocorre não só por questões de espessura do segmento, e pode sofrer influência de outros fatores, como adaptação neural e composição corporal.
