There is a high prevalence of UI yet low levels of adequate knowledge and practice regarding the occurrence of UI in sports, with sports practice time over 8 years and dyspareunia factors predisposing female athletes to UI by 2.7 and 3 times, respectively. Athletes with adequate knowledge were 57% less likely to develop UI.

ABSTRACT:Objectives: The purpose this study was to investigate the effects of different vascular occlusion levels (total occlusion (TO), partial occlusion (PO) or free flow (FF)) during intermittent isometric handgrip exercise (IIHE) on the time to failure (TF) and the recovery of the maximum voluntary isometric force (MVIF), median frequency (EMGFmed) and peak of EMG signal (EMGpeak) after task failure. Methods: Thirteen healthy men (21 ± 1.71 year) carried out an IIHE until the failure at 45% of MVIF with TO, PO or FF. Occlusion pressure was determined previously to the exercise. The MVIF, EMGFmed and EMGpeak were measured before and after exercise. Results: TF was significantly different (p < 0.05) among all investigated conditions: TO (150 ± 68s), PO (390 ± 210s) and FF (510 ± 240s). The MVIF was lower immediately after IIHE, remaining lower eleven minutes after failure in all cases (p <0.05), when compared to pre exercise. There was a greater force reduction (p <0.05) one minute after the failure in the PO (-45.8%) and FF (-39.9%) conditions, when compared to TO (-28.1%). Only the PO condition induced lower MVIF (p <0.05) than in the TO, eleven minutes after the task failure. PO induced a greater reduction in EMGFmed compared TO and greater increase in EMGpeak, when compared to TO and FF (p <0.05). Conclusions: TO during IIHE lead to a lower time to failure, but a faster MVIF recovery, while the PO seems to be associated to a slower neuromuscular recovery, when compared to other conditions.

Objective To assess the effect of pelvic patterns of proprioceptive neuromuscular facilitation (PNF‐concept) on pelvic floor muscles (PFM) recruitment, as well as the electromyographic activity of muscles synergic to the pelvic floor in healthy women. Methods Observational study conducted with 31 women aged between 18 and 35 years, with mean age of 23.3 ± 3.2 (22.1–24.4). PFM activity was monitored by surface electromyography during the combination of isotonics technique of four pelvic patterns of PNF‐concept (i.e., anterior elevation, posterior depression, anterior depression, and posterior elevation). The electromyographic signal was analyzed using root mean square amplitude. Two‐way repeated measures analysis of variance was performed to analyze differences in PFM activity between types of contraction (i.e., concentric, isometric, and eccentric) and the four pelvic patterns. Results PFM activity did not differ among the four pelvic pattens. However, PFM activity was significantly different between the combination of isotonics technique and baseline, F(1.6, 48.2) = 71.5; p < 0.000, with a large effect size (partial ƞ² = 0.705). Concentric (22.4 µV ± 1.1), isometric (17.3 µV ± 0.6), and eccentric (15 µV ± 0.5) contractions of combination of isotonics technique increased PFM activity compared with baseline (10.8 µV ± 0.4) in all pelvic patterns. By analyzing the electromyographic activity of the muscles synergistic to the pelvic floor, there is effect of the interaction of the type of contraction, the pelvic pattern of the PNF concept, and the synergistic muscles on the myoelectric activity of the external anal sphincter, F(3.2, 96.5) = 5.6; p < 0.000, with a large magnitude of effect (partial ƞ² = 0.15). In the anterior elevation pattern, the muscles synergistic to the pelvic floor present synergy in phase with the PFM, and in the posterior patterns there was a decrease in the activity level of all synergistic muscles, without changing the activity level of the PFM. Conclusion PFM activity did not differ among the four pelvic patterns of PNF‐concept. Nonetheless, the combination of isotonics technique showed a significant effect on PFM compared with baseline, with greater PFM activity during concentric contraction. Pelvic patterns of PNF‐concept may be used to increase PFM recruitment in young healthy women.

RESUMO O objetivo deste estudo foi avaliar a prevalência, o conhecimento e os fatores associados à incontinência urinária (IU) em mulheres estudantes de um curso de fisioterapia, bem como sua qualidade de vida. Foi aplicada uma ficha de avaliação, o International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) e um questionário de conhecimento sobre a musculatura do assoalho pélvico (MAP) e a ocorrência de IU, baseado em estudo tipo conhecimento, atitude e prática (CAP). Das 248 estudantes do curso, 170 (69%) participaram do estudo. Pela ficha de avaliação, 111 (65%) relataram perda urinária. De acordo com o ICIQ-SF, 63 participantes (37%) são incontinentes, sendo que 41 (65%) dessas apresentam IU de esforço, apresentando pequena perda e com frequência de uma vez na semana ou menos, com baixo impacto na sua qualidade de vida. A maioria das participantes que relataram ter dor na relação sexual (59%) e alguns sintomas uroginecológicos e intestinais, como esforço ao urinar (92%), jato interrompido (75%), incômodo na região vaginal (73%), constipação (53%), esforço ao defecar (53%) e esvaziamento intestinal incompleto (70%), apresentou queixa de IU. Todas as que usam protetor (100%) e procuraram atendimento médico (100%) eram incontinentes. O uso de anticoncepcional foi maior em mulheres sem perda urinária (84%). O conhecimento sobre a MAP e a IU foi adquirido gradualmente com o avançar do curso. Esse resultado sugere que as mulheres que não cursam Fisioterapia não têm domínio do assunto, sendo necessário disseminar o conhecimento sobre a IU e a atuação da fisioterapia.
