Two Years of COVID-19 Pandemic: How the Brazilian Serie A Championship Was Affected by Home Advantage, Performance and Disciplinary Aspects.

As a result of the COVID-19 pandemic, the Brazilian Serie A championship was played without crowds in 2020 and partially in the 2021 season. We verified if the home advantage (HA) was different between the 2018, 2019, 2020, and 2021 seasons. We also compared the HA, performance, and disciplinary aspects between the rounds with or without crowds and verified the association between the number of absent athletes because of health protocols and the HA in the 2020 and 2021 seasons.

Sleep extension in athletes: what we know so far - A systematic review.

Objective: This study reviewed systematically the effects of sleep extension on sports performance.

Design: Systematic review.

Method: The systematic review was conducted in November 2020.

Can IGF-1 Serum Levels Really be Changed by Acute Physical Exercise? A Systematic Review and Meta-Analysis.

Background: Physical exercise plays an important role in metabolic health, especially in the insulin-like growth factor-1 (IGF-1) system. The objective of this study was to perform a systematic review and meta-analysis to evaluate the effects of a single endurance and resistance exercise session on IGF-1 serum.

Methods: The systematic review was performed in SPORTDiscus, MEDLINE, PubMed, and Google Scholar databases.

Perceived Exertion and Affect From Tai Chi, Yoga, and Stretching Classes for Elderly Women.

Tai Chi, yoga, and stretching regimens are gaining popularity as alternatives to more traditional exercise, but there is scant research regarding participants' perceived exertion and affective responses to these practices. We compared experienced states of perceived exertion, feelings of pleasure/displeasure, and arousal in 70 elderly women enrolled in groups of Tai Chi ( n = 26), yoga ( n = 25), or stretching ( n = 19) classes. Mean rates of perceived exertion, feelings of pleasure, and arousal responses were significantly higher over the time course of all three groups, while the overall mean perceived exertion ( Somewhat Hard on the Borg CR-10 scale) and pleasure responses (∼ Very Good on the Feeling Scale) were similar between them.

Effect of Music Tempo on Attentional Focus and Perceived Exertion during Self-selected Paced Walking.

This study investigated the influence of music on the rating of perceived exertion (RPE) and attentional focus during walking at a self-selected pace. Fifteen overweight and obese women volunteered to participate in the study. They underwent four sessions: the first for incremental maximal test and anthropometric measurement followed by three experimental sessions.

Ethnopharmacological Relevance: Plectranthus amboinicus (Lour.) Spreng is a medicinal specie often used in Brazil, especially in Northeast Region, for the treatment of several diseases including inflammations and cancer.

Aim Of The Study: To evaluate the anti-inflammatory and antitumor activities of the hydroalcoholic extract from leaves of P.

Toxicological assessment of beta-lapachone on organs from pregnant and non-pregnant rats.

Naphthoquinones have been studied extensively due to their activity as topoisomerase inhibitors. These enzymes are critical to DNA replication in cells. beta-Lapachone (beta-lap) is an o-naphthoquinone chemically obtained from lapachol.

Toxicological screening of Euphorbia tirucalli L.: developmental toxicity studies in rats.

Euphorbia tirucalli (Euphorbiaceae family), an environmental risk factor for Burkitt's lymphoma, also presents pharmacological activities. In the northeast region of Brazil its latex is used as an antimicrobial, antiparasitic in the treatment of coughs, rheumatism, cancer and other maladies as folk remedy. The present work concerns its developmental toxicity in rats.
