Introduction. The aim of the study was to investigate the hypotensive responses in normotensive trained individuals after strength training (ST) performed using two training methods: DeLorme and Oxford. Material and methods. Fifteen normotensive trained men (age: 25.1 ± 3.2 years; height: 1.78 ± 0.01 m; BMI: 24.78 ± 1.4 kg/m2) were examined alternately in crossover with an interval of 72 hours between the DeLorme and Oxford methods. Firstly, 10 repetition maximum (RM) loads were obtained. DeLorme (50%, 70%, and 90%) and Oxford (90%, 70%, and 50%) consisted in the manipulation of 10RM loads so that the subjects performed three sets until failure in the Smith Machine (SM) and the Leg Press 45° (LP). Blood pressure was recorded at rest, post-exercise, and until 60 min post-session at 10-min intervals. Results. Both the DeLorme and Oxford methods showed significant intra-protocol reduction in systolic blood pressure (SBP) at 40, 50, and 60 min time points compared to the rest value (F = 21.848; p = 0.0001). Similar results were noted for diastolic blood pressure (DBP) between rest value and the 60 min time point (F = 46.113; p = 0.0001). Conclusions. The DeLorme and Oxford resistance training methods provided similar hemodynamic responses and similar hypotensive effects. Therefore, these methods can be used as alternatives to manipulate training intensity-volume ratio intra-session with low hemodynamic stress.

The aim of this study was to investigate the acute effect of intra-set antagonist static stretching (hamstrings) on the performance of maximum repetitions of knee extensors adopting muscle endurance training zone. The sample consisted of 15 healthy male volunteers with experience in strength training (23.7 ± 4.3 years, 81.9 ± 15.0 kg, 1.8 ± 0.1 m). Two experimental protocols were conducted: protocol without static stretching (PT) and antagonist stretching protocol (PAA) in the knee extension exercise. The results showed that there was no difference between protocols or interactions between protocols and sets in maximum repetitions performance (PT, set1 – 21.3 ± 3.4; set2 – 16.1 ± 1.9; set3 – 13.5 ± 1.3 / PAA, set1 – 21.0 ± 2.0; set2 – 16.7 ± 2.6; set3 – 13.7 ± 2.2) (p ≤ 0.05) (p ≤ 0.05). Therefore, antagonist static stretching does not influence performance of maximum repetitions of knee extensors over multiple sets focused on muscle endurance.

This study aimed to analyze the performance of the vertical jump with counter movement (CMJ), in university handball athletes, immediately after the maximum strength training in multiple series and after 10 and 15min of rest. Twelve male athletes participated, age 20.9±2.4 years old, height 1.78±0.05m and Body Mass Index (BMI) 28.74±8.1kg/m2. After the tests and retests of 1 repetition maximum (1RM) for the dominant and non-dominant sides, in the leg extension, the volunteers performed crossover after 48 hours of the training sessions. CMJ measurements were collected before and immediately after each training protocol and after 10 and 15min of rest. Passive recovery between sets was three minutes. The intervals between training protocols were at least 45min. There were no statistical differences for the CMJ between the moments pre-, post-training session, 10 and 15min of rest in the different protocols, but progressive increases in the CMJ variables were observed, extending up to the 15th minute of rest, in all training protocols when comparing the results of the means of the CMJ variables of the moments post-training session, 10 and 15min of rest with the averages of the variables from the pre-training session, being more evident in the alternate unilateral protocol, which, unlike the other protocols of the study, performed series with the two lower limbs. It was evidenced that the training protocols of short duration and with high dynamic efforts, previously performed, influenced the performance of the CMJ, favoring for the transient improvement of the explosive muscular strength of the athletes.

SummaryStudy aim: To evaluate the effect of power and muscle strength training on skin temperature and the performance of the vertical jump with countermovement (CMJ).Material and methods: The sample consisted of four male basketball athletes of the under-17 category (age: 15.75 ± 1.0 years). 48 hours after anthropometric evaluation and determination of the loads for 1 repetition maximum (1RM) in the leg extension exercise, the athletes were subjected, through crossover-type entrance, to power (PTP) and strength (STP) training protocols. The protocols consisted of three sets with loads of 60% and 90% of 1RM for PTP and STP, respectively. Thermographic images of the thighs were taken before and immediately after each training session.Results: There were significant differences in results between the two training protocols, with increased total repetitions (t = 13.481; p < 0.05) and total training volume (t = 15.944; p < 0.05) in the PTP, and increase in the % of 1RM (t = 33.903; p < 0.05) and rating of perceived exertion (t = 6.755; p < 0.05) in the STP. The skin temperature before and after PTP and STP showed no significant differences. In the post-STP, the CMJ presented significant reductions in height (t = 3.318; p < 0.05), flight time (t = 3.620; p < 0.05), velocity (t = 3.502; p < 0.05), and force (t = 4.381; p < 0.05). There were no significant differences in pre-and post-STP CMJ.Conclusions: Power and maximum strength training in the leg extension exercise performed until concentric failure appears to be a method that induces thermal stress on the skin. This training directly influenced the performance of the vertical jump after the stimulus.

Esta revisão integrativa da literatura objetivou analisar os exergames como possibilidade de recurso pedagógico motivador para o aumento da prática de exercícios físicos e gasto energético nas aulas de Educação Física. Foram utilizados os descritores “Educação Física”, “exergames”, “videogames”, “jogos eletrônicos” e “inclusão”, nas bases de dados eletrônicas MedLine (via PubMed), ERIC, Scopus, SciELO, Redalyc, Campbell Collaboration e Google Scholar. Foram selecionados 16 artigos originais indexados pelo Qualis Periódicos (nove em português e sete em inglês), categorizados em exergames e a influência motivadora; exergames e gasto energético; exergames e alunos com deficiência. Os resultados indicaram que o uso dos exergames como intervenção pode ser uma alternativa pedagógica motivadora e ferramenta de aumento do gasto energético na prática de exercícios físicos nas aulas de Educação Física, pois abarcam o movimento corporal conjugado à ludicidade e incitação, sendo bem aceito pelos alunos sem ou com deficiência. Compreende-se que o caráter do divertimento que os exergames apresentam podem ser um dispositivo facilitador. O mundo fantasioso criado pela ludicidade dos jogos digitais, que requerem realização de atividades físicas, possibilita aumentar o gasto energético e colabora na aprendizagem e desenvolvimento motor.

Introdução: A pandemia causada pelo novo Coronavírus (COVID-19) se tornou um dos grandes tormentos do século XXI. O distanciamento social foi adotado como medida para evitar o avanço da pandemia. Apesar de necessário, esse confinamento pode desencadear transtornos emocionais. A atividade física tem efeitos positivos sobre o bem-estar físico e a saúde mental, incluindo a possibilidade de redução de sofrimentos psicológicos. Objetivo: Descrever o impacto da prática de atividades físicas sobre os níveis de ansiedade durante o isolamento social devido à COVID-19, entre jovens e adultos. Métodos: Foi realizada uma revisão integrativa de acordo com as recomendações dos principais itens para relatar Revisões Sistemáticas e Meta-análises (PRISMA). As buscas foram realizadas entre maio e julho de 2021 nas bases de dados eletrônicas APA PsycINFO, Medline (via PubMed) e Lilacs (via BVS). Resultados: Dos 95 artigos científicos encontrados, 12 foram considerados elegíveis. Os estudos analisados mostraram que, durante o confinamento, as mulheres se tornaram menos ativas fisicamente, enquanto os homens realizaram mais atividades físicas e apresentaram níveis menores de ansiedade. Adicionalmente, quanto mais altos os escores da prática de atividades físicas, menores foram os sintomas de ansiedade. Conclusão: Os indivíduos que se mantiveram fisicamente ativos ou aumentaram a quantidade de atividades físicas diárias com intensidades moderadas e/ou vigorosas apresentaram menores níveis de transtornos psicológicos durante o distanciamento social imposto pela COVID-19.
