A review on muscle activation behaviour during gait in shallow water and deep-water running and surface electromyography procedures.

Background: Surface electromyography (sEMG) can provide information on muscle activation patterns during gait.

Objectives: To characterize electromyographic activity during gait in shallow water and during deep-water running compare to on land and to review and analyse underwater surface-electromyographic (sEMG) procedures.

Search Methods: Eight databases (MEDLINE, EMBASE, WEB OF SCIENCE, SPORT Discus, CINAHL, SCOPUS, SCIELO, and LILACS) were searched from their inception to the December of 2019.

Postural Sway, Balance Confidence, and Fear of Falling in Women With Knee Osteoarthritis in Comparison to Matched Controls.

Background: Osteoarthritis (OA) is a chronic degenerative disease that commonly affects the knee joints. Individuals older than 65 years of age with knee OA have a greater risk of falls. However, there has been limited examination of the parameters of postural sway (increased time, speed, and postural sway area [center of pressure{CoP}]), and OA of the knee.

[Low agreement between the fitnessgram criterion references for adolescents].

Objective:: To analyze the association and agreement of reference criteria (RC) for cardiorespiratory fitness, body mass index (BMI) and strength in youth.

Methods:: The study included 781 youth, 386 females, aged 10 to 18 years of Londrina-PR. It were performed cardiorespiratory fitness and muscular strength tests and was calculated body mass index.
