Exclusion criteria: a) narrative reviews </span><span lang="EN-US">were systematic reviews or meta-analyzes, b) studies applied to children, adolescents and the elderly c) articles that are not indexed. The search for articles in the databases yielded a total of 2561 results (Pubmed = 48 and Science Direct = 2513) in a period of time from August to October 2021, articles were selected by title and / or Abstract, when applying the Inclusion and exclusion criteria, a total of 5 original articles were obtained. <strong>Result</strong></span><strong><span lang="EN-US">:</span></strong><span lang="EN-US"> the results show variance towards the decrease in adipose tissue, showing that HIIT is a favorable and applicable tool in the overweight and obese population. Conclusion: The information collected shows the enhancing effects of physical training and its favorable effects on the reduction of adipose tissue. Faced with this, HIIT is presented as a useful non-pharmacological and low-cost alternative, which, when applied, controlled and adapted correctly, amplifies its beneficial effects. </span> A.

Some studies have shown that individuals who are doing more physical activity would reduce the symptoms of depression. <strong>Objective: </strong>to determine which physical exercise methodology generates the greatest effects in adult patients with depressive disorders. <strong>Material and methods:</strong> PubMed, Web of Science and Scopus were searched. The eligibility criteria were established based on the PICO acronym of randomized and controlled studies published between 2010 and 2020: (P) adults between 18 and 64 years of age, (I) systematic physical exercise, (C) no physical activity and / or the combination with the use of drugs, (O) effects of systematic physical exercise on the parameters that measure depression. <strong>Results: </strong>10242 articles were identified, of which only 16 met the inclusion criteria. <strong>Conclusion</strong>:</span><span lang="EN-US"> </span><span lang="EN-US">It is not possible to ascertain which modality generates the greatest benefits in adult patients with depression. What is shown is that the aerobic exercise modality is the most studied and used. More comparative studies between the different exercise modalities are needed to be able to assess whether or not this difference exists. </span> Pedro Ampuero Ibáñez Yohana Cáceres Muñoz Juan Inostroza Silva Christian Campos Jara Copyright (c) 2022 Revista Horizonte https://creativecommons.org/licenses/by-nc-sa/4.0 2022-11-24 2022-11-24 1 24 18 36 10.32735/S0718-8188202224168 https://revistahorizontecaf.ulagos.cl/index.php/revhorizonte/article/view/169 <span lang="EN-US">Measuring the anaerobic threshold as a reference parameter for respiratory capacity has been considered appropriate in the estimation of different intensity domains during exercise, used in the development of training programs and measurement of sports performance in middle-distance and long-distance athletes. <strong><span style="text-decoration: underline;">Objective</span>:</strong> To analyze and compare the effectiveness of the anaerobic threshold as a tool in the different training methods oriented to the sports performance training methods oriented to sports performance in young middle-distance and long-distance athletes. <strong><span style="text-decoration: underline;">Material and Methods</span>:</strong> A search was carried out in Dialnet, Ebscohost, PubMed and Scielo.

O objetivo do estudo foi determinar os níveis de estresse e ansiedade de adolescentes entre 12 e 17 anos envolvidos em educação recreativa e voleibol competitivo.Um estudo explicativo descritivo, básico com métodos qualitativos e quantitativos. Composto por 35 jogadores das equipes de voleibol do Projeto Social VivaVôlei e Lavras Tênis Clube (LTC), da cidade de Lavras/MG. Aplicou-se o Teste de Estresse Psicológico do Voleibol (TEP V) e a Escala de Traços de Ansiedade Competitiva. Processamento estatístico utilizando o programa estatístico R, teste do qui-quadrado, teste "U" de Mann-Whitney com intervalo de confiança de 95%, Alpha Cronbach e análise da média, mediana, desvio padrão, quartis e distribuições de valores. Os níveis de ansiedade foram homogêneos entre os sexos. O gênero do atleta não afeta a forma como ele expressa seu nível de ansiedade. Entre os estressores, os resultados sugerem que as atletas do sexo feminino são mais suscetíveis aos fatores emocionais, os atletas do sexo masculino geralmente percebem as situações estressantes como positivas ou irrelevantes para o seu desempenho. Por meio de cálculos estatísticos concluiu-se que não houve diferenças significativas entre as equipes VivaVôlei e LTC quanto à ansiedade, estresse e gênero do atleta. Percebe-se que os esportes presentes no estudo não são fatores mediadores dos problemas apresentados nesta amostra.es</p> Tamires Helena Da Silva Joice Benedita Silva Amanda Siqueira de Castro Nathália Aparecida dos Santos Camila Mariana de Lima Marcelo de Castro Teixeira Copyright (c) 2022 Revista Horizonte https://creativecommons.org/licenses/by-nc-sa/4.0 2022-07-04 2022-07-04 1 24 53 69 10.32735/S0718-8188202224176
