Variability of energy cost in breaststroke technique: a systematic review.

This study aimed to synthesise the body of knowledge on kinematics, active drag and energetics determinants of energy cost variability in the breaststroke technique. Methodological procedures considering the standards for systematic reviews according to the '"Preferred Reporting Items for Systematic Reviews and Meta-Analyses"' were employed. Searches were conducted in four prominent databases.

Exploring the impact of breathing patterns on active drag in breaststroke swimming.

This study aimed to compare active drag (D), coefficient of hydrodynamic force (C) and, total external mechanical power (P) between two breathing patterns in breaststroke: breathing every stroke versus every two strokes. A 6-week intervention program was conducted. Fifteen swimmers carried out two all-out bouts of 25 m using the velocity perturbation method in each breathing pattern.

How Anthropometrics of Young and Adolescent Swimmers Influence Stroking Parameters and Performance? A Systematic Review.

The purpose of this systematic review was to investigate the relationship between anthropometric characteristics, biomechanical variables and performance in the conventional swimming techniques in young and adolescent swimmers. A database search from 1 January 2001 to 30 June 2021 was done according to the PRISMA statement, with 43 studies being selected for analysis. Those manuscripts were divided in butterfly, backstroke, breaststroke and front crawl techniques as main categories.

Health care in a community of followers of traditional African-Brazilian religions.

Objective: To understand the concept of health and the source of psychological distress among followers of a traditional African-Brazilian religion.

Methodological Procedures: Qualitative study performed in a community of followers of a traditional African-Brazilian religion, in the city of Porto Alegre, Southern Brazil, between 2007 and 2008. The priest/Babalorixá and six followers of this community participated in the study.
