Abstract

(1) Background: Stretching is known to improve range of motion (ROM), and evidence has suggested that strength training (ST) is effective too. However, it is unclear whether its efficacy is comparable to stretching. The goal was to systematically review and meta-analyze randomized controlled trials (RCTs) assessing the effects of ST and stretching on ROM. (2) Methods: Cochrane Library, EBSCO, PubMed, Scielo, Scopus, and Web of Science were consulted in October 2020 and updated in March 2021, followed by search within reference lists and expert suggestions (no constraints on language or year). Eligibility criteria: (P) Humans of any condition; (I) ST interventions; (C) stretching (O) ROM; (S) supervised RCTs. (3) Results: Eleven articles (n = 452 participants) were included. Pooled data showed no differences between ST and stretching on ROM (ES = 􀀀0.22; 95% CI = 􀀀0.55 to 0.12; p = 0.206). Sub-group analyses based on risk of bias, active vs. passive ROM, and movement-per-joint analyses showed no between-protocol differences in ROM gains. (4) Conclusions: ST and stretching were not different in their effects on ROM, but the studies were highly heterogeneous in terms of design, protocols and populations, and so further research is warranted. However, the qualitative effects of all the studies were quite homogeneous.

Abstract

The goal of this systematic review was to evaluate the effects of exercise programs using agility ladders and to assess the quality of available evidence. Search was conducted in October of 2019 using the following databases: Cochrane Library, PEDro, PubMed, Scopus and Web of Science. Study eligibility criteria included randomized trials or randomized controlled trials using agility ladders drills. Participants were healthy humans of any health status. The study appraisal and synthesis methods followed the revised Cochrane risk-of-bias tool for randomized trials (RoB 2) and a qualitative synthesis of the main results of each study were applied. Only five studies met our criteria, lasting between 4 and 8 weeks. Only two studies evaluated the effects of ladder drills on more than one dimension. Lack of description of the specific exercises that were used limits reproducibility of current studies. With one exception, the articles had low risk of bias for most domains. Despite the widespread popularity of agility ladder drills, research is scarce and problematic, with poorly described protocols and mostly unidimensional performance measures. Claims that agility ladders improve agility and other physical skills is premature, given the nature and quality of existing research.

Abstract

Objective: The number of people suffering from depression and/or anxiety has increased steadily due to the coronavirus disease 2019 (COVID-19) pandemic. In this context, web-based exercise interventions have emerged as a potential treatment strategy. The objective of this study was to synthetize evidence from randomized controlled trials regarding the effects of web-based exercise interventions on patients with depressive and/or anxiety disorders. Methods: Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. Six databases were searched (Cochrane Library, EBSCO, PubMed, SciELO, Scopus, and Web of Science), and eligible articles were identified according to a PICOS inclusion-exclusion approach (participants with depressive or anxiety disorders; web-based exercise interventions; active or passive control group; assessment of changes in depressive or anxiety disorders; randomized design). Primary outcomes were depressive and/or anxiety symptoms. The quality of evidence was assessed with Grading of Recommendations Assessment, Development, and Evaluation. Results: Of 7,846 search results, three studies met the inclusion criteria (172 participants between 18 and 65 years of age, 95.9% women). The web-based exercise interventions lasted 8-12 weeks and involved endurance training, yoga, or combined endurance and strength training. The comparators involved non-exercise controls or active controls. Compliance rates were low. Web-based exercise interventions were not superior to controls regarding anxiety symptoms, and only one study found benefits for depressive symptoms (p p 0.05). The quality of the cumulative evidence was low. Conclusion: The available data regarding the effects of web-based exercise interventions on depression and/or anxiety symptoms is scarce, the risk of bias is high, and the quality of the cumulative results is low. Currently, no clear recommendations can be provided.

O Salto Vertical com Contramovimento (CMJ) é um indicativo de prontidão, fadiga e performance neuromuscular.

Valores altos = melhor desempenho

Valores baixos = pior desempenho

Medir valores após a ativação, antes e após o treino.

A Variabilidade da Frequência Cardíaca (VFC) é um indicador de stress e recuperação do sistema nervoso central da pessoa.

Valores altos = maior recuperação

Valores baixos = maior stress

Medir logo ao acordar.

Utilizar dispositivos como: 

“whoop”, “apple watch”, “polar”, “garmin”, “fitbit” ou app “HRV4Training”.

A escala de Bem-Estar (BE) aborda diversos fatores que contribuem para a saúde física e mental da pessoa.

Valores altos = maior bem-estar
