INTRODUCTION: Abdominal hypopressive gymnastics appeared as an alternative to traditional abdominal exercises to promote abdominal muscles strength without overloading the pelvic floor muscles (PFM). To determine the activation level of abdominal muscles and PFM and the posture influence in the level of activation in these muscles during abdominal hypopressive gymnastics, we used surface electromyography in young and healthy multipara women. METHODS: This is an observational study with eutrophic nulliparous women aged between 18 and 35 years, with abdominal skinfold less than or equal to 3 cm and active or irregularly active physical activity...

BACKGROUND: Generalized Joint Hypermobility (GJH) is suggested as a contributing factor for injuries in young athletes and adults. It is presumed that GJH causes decreased joint stability, thereby increasing the risk of joint and soft tissue injuries during sports activities. The aim of this study was to determine the correlation between the hypermobility rate (using the Beighton`s modification of the Carter-Wilkinson criteria of hypermobility) in gymnasts and injury rate, during the period of one year...

Many strength training (ST) programs incorporate pushup exercises, which primarily activate upper body muscles. Past data supports the fact that shoulder girdle muscles [i.e., triceps (T) and anterior deltoids (AD)] exhibit greater electromyography (EMG) activity when a pushup is performed on an unstable [i.e., suspended (SP)] vs. stable [i.e., traditional (TD)] surface (Andrade, 2011). Sixty-nine healthy female volunteers [soccer players (SO), n=24; gymnasts (GY), n=21; sedentary (SE), n=24) performed three TD and three SP pushups...

BACKGROUND: Osteochondral autologous transplantation surgery (OATS) has been advocated for unstable osetochondritis dissecans (OCD) lesions of the adolescent capitellum, though limited information is available regarding clinical and radiographic results in North American patients. We hypothesize that single-plug OATS is safe and effective in alleviating pain and restoring function in unstable OCD. METHODS: Twenty-eight patients with unstable OCD treated with single-plug OATS were evaluated...

Prevention of dementia is a public health priority. Physical activity (PA) can reduce the risk of dementia, but the majority of people remain sedentary. We conducted a multicenter controlled study with older adults (60+ years). We hypothesized that an evidence-based PA intervention - GEhen, Spielen und Tanzen Als Lebenslange Tätigkeiten - kompakt [walking, playing and dancing as lifelong activities-compact] (GESTALT-kompakt) - would lead to significantly larger improvements in PA levels (step counts/Fitbit Zip™), cognitive functions (DemTect) and social activities (Social Activity Log), compared to an active control group...

Left-to-right readers are assumed to demonstrate a left-to-right bias in aesthetic preferences and performance evaluation. Here we tested the hypothesis that such bias occurs in left-to-right reading laypeople and gymnastic judges (n = 48 each) when asked to select the more beautiful image from a picture pair showing gymnastic or non-gymnastic actions (Experiment 1) and to evaluate videos of gymnasts' balance beam performances (Experiment 2). Overall, laypeople demonstrated a stronger left-to-right bias than judges...

Brain white matter (WM) could be generally categorized into two types, deep and superficial WM. Studies combining these two types WM are important for a better understanding of brain plasticity induced by motor training. In this study, we applied both univariate and multivariate approaches to study gymnastic training-induced plasticity in brain WM. Specifically, we acquired diffusion tensor imaging data from 13 world class gymnasts and 14 non-athlete normal controls, reconstructed brain deep and superficial WM tracts, estimated and compared their fractional anisotropy (FA) difference between the two groups...

Hip problems due to dysplasia are commonly associated with female athletes in sports demanding supraphysiologic motion, such as ballet, gymnastics and figure skating. However, hip problems are rarely mentioned among wrestlers, a male sport in which flexibility is advantageous. Dysplasia may have a mostly unrecognized prevalence among wrestlers that can lead to problems and benefit from reorientation periacetabular osteotomy (PAO). Study design in this research is Level 4 evidence case reports. Three consecutive intercollegiate wrestlers ages 20, 21 and 22 years underwent PAO for dysplasia and are reported...

BACKGROUND: Activities in the aquatic environment can be an interesting alternative of physical exercise for the elderly, due to several properties of water, which can favor the physiological, metabolic, perceptive, and musculoskeletal effects. OBJECTIVE: To compare the effects of performing two hydrogymnastic class methodologies on the functional capacity and flexibility in elderly women. METHODS: 90 women, aged 55-70 years, were divided into three groups, the Control Group (CG; n= 30) who did not exercise during the 12 weeks, Experimental Group 1 (EG1; n= 30), who performed water gymnastics classes with emphasis on lower limb exercises for 12 weeks, and Experimental Group 2 (EG2; n= 30), who performed conventional hydrogymnastics classes for 12 weeks...

BACKGROUND: Hypopressive abdominal gymnastics has been proposed as a new paradigm in rehabilitating the pelvic floor. Its claims contraindicate the recommendation for pelvic floor muscle training during the postpartum period. OBJECTIVE: To determine whether hypopressive abdominal gymnastics is more effective than pelvic floor muscle training or other alternative conservative treatments for rehabilitating the pelvic floor. METHODS: We consulted the databases of the Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Cochrane Library, Latin American and Caribbean Health Sciences Literature (LILACS), Physiotherapy Evidence Database (PEDro), PubMed, Scopus, Trip Database and Web of Science...

A pure somersault is a key skill in diving and gymnastics, and involves rotation about the transverse axis of the body. As the rotational speed increases the effort required to maintain a specified posture increases. This paper derives equations for the joint moments required for an athlete to hold three sport specific postures as a function of rotational speed. The joint moment is related to the isometric muscular strength and is the limiting factor of an athlete in their ability to hold a fixed posture while somersaulting...
