Métodos: Realizou-se uma revisão sistemática integrativa da literatura nos bancos de dados PUBMED, LILACS e SCIELO. Utilizou-se o método Prisma e foram selecionados 32 artigos, sendo 18 incluídos. Adicionalmente, foram utilizadas seis referências para discussão e conclusões. Resultados: A revisão literária identificou diversos fatores individuais que influenciam negativamente na aderência aos programas de exercícios físicos para idosos. Estes fatores incluem pertencer ao gênero masculino, ter idade avançada, ter baixo status social (renda e escolaridade), histórico de tabagismo, autoavaliação negativa da condição de saúde em comparação com alguém da mesma idade, c...

Methods: A Prospective 12-Week Follow-Up Of 452 Individuals Selected From Crossfit" Boxes From The Metropolitan Area Of São Paulo, Brazil, In 2016 And 2017. Data Were Collected From An Initial Sample Characterization Questionnaire Followed By Six Electronic Questionnaires Sent Biweekly By Email With Questions Regarding Training Frequency And Injury Occurrence. A Time-Loss Injury Definition Was Used And Injuries Were Classified By The Anatomical Location And Injury Type. Risk Factors Such As Age, Body Mass, Previous Injuries, Experience (Years Of Practice), Training Load, Preventive Exercises, Use Of Protective Equipment, Supervision Of Trainers, And Participation In Competitions Were Investigated. Data Analysis Were Performed Through Descriptive Statistics And Logistic Mixed Models. Results: 1618 Responses Out Of 406 Participants...

Purpose: To investigate the incidence (cumulative incidence proportion [IP] and incidence density [ID]) of CRMIs and the association of CRMIs with personal and training characteristics. Study Design: Descriptive epidemiology study. Methods: A prospective, 12-week descriptive epidemiology cohort study was conducted in a convenience sample of CrossFit facilities in a single Brazilian city. Printed baseline questionnaires were distributed to 13 CrossFit boxes. All participants who filled out the questionnaire and consented to participate in the study were invited to respond to an online follow-up questionnaire every 2 weeks to collect data on CrossFit training characteristics and CRMIs. A CRMI was defined as any self-reported musculoskeletal injury or pain that prevented an athlete from exercising for at lea...

Traumatic sports injuries and surgical procedures (open and arthroscopic) can cause vascular damage. Little attention has been devoted to establish safe parameters for the MGA. To investigate the anatomy of the MGA and its relation to the posterior structures of the knees, mainly the posterior capsule and femoral condyles, and to establish safe parameters to avoid harming the MGA. Descriptive laboratory study. Dissection of the MGA was performed in 16 fresh, unpaired adult human cadaveric knees with no macroscopic degenerative or traumatic changes and no previous surgeries. The specimens were meticulously evaluated with emphasis on preservation of the MGA. The distances from the MGA to the medial and lateral femoral condyles were measured. The Mann-Whitney test was used for statistical analysis. In all specimens, the MGA emerged from the anterior aspect of the poplite...
