ABSTRACT Introduction: Overweight negatively impacts the cardiovascular system and osteomyoarticular, promoting pain in the joints of the lower limbs. Therefore, strategies have been applied to reduce overweight through lifestyle changes. Objective: To investigate the effects of two multidisciplinary intervention programs on the health-related physical fitness of obese women with pain symptoms in the knees. Methods: Women between 40 and 59 years of age with obesity (n=59) were evaluated pre- and post-intervention in terms of anthropometry, body composition, physical fitness, level of disability in the knee and hip, and health-related quality of life. A randomized experimental study of parallel groups was conducted for 8 weeks, using two resistance exercise programs and food reeducation. All participants received the same nutritional interventions. For physical exercises, the participants were randomized into two groups: G1, the “strength group” using machines (n=30), and G2, the “body weight” group (n=29). Twenty-eight women (G1, n=18; G2, n=10) were included in the final analyses. This study was approved by Ethics Local Committee. The groups and time were evaluated using two-way analysis of variance with repeated measures. A p<0.05 was assumed for all analyses. Results: A time effect was identified, with higher values for maximum isometric lumbar traction strength after the intervention period in both groups (p<0.05). However, no significant differences were identified among the other variables investigated (p>0.05). Conclusion: The absence of significant results for all variables, except maximum isometric lumbar traction, may be justified by the moderate adherence of the participants to interventions (approximately 59%-66%) since the study was conducted during the period of social isolation (COVID-19). However, it is believed that the intervention models were positive in maintaining the variables studied.

RESUMEN Introducción: El sobrepeso afecta negativamente al sistema cardiovascular y al osteomioarticular, favoreciendo el dolor en las articulaciones de las extremidades inferiores. Por lo tanto, se han aplicado estrategias para reducir el sobrepeso a través de cambios en el estilo de vida. Objetivo: investigar los efectos de dos programas de intervención multidisciplinares sobre la aptitud física relacionada con la salud de mujeres obesas con síntomas de dolor en las rodillas. Métodos: Se evaluó a mujeres entre 40 y 59 años con obesidad (n=59) en el tiempo pre y post intervención en antropometría, composición corporal, aptitud física, nivel de discapacidad en rodilla y cadera y calidad de vida relacionada con la salud. Se realizó un ensayo clínico aleatorizado de grupos paralelos, utilizando dos programas de ejercicio de resistencia y reeducación alimentaria, durante ocho semanas. Todos los participantes recibieron el mismo contenido de intervención nutricional y para ejercicios físicos se aleatorizaron en dos grupos, G1 siendo el "grupo de fuerza" utilizando máquinas (n=30), y G2 siendo el grupo de "entrenamiento funcional" (n=29). Veintiocho mujeres (G1=18 + G2=10) fueron incluidas en los análisis finales. Este estudio fue aprobado por el Comité Local de Ética. Los grupos y el tiempo se evaluaron mediante análisis bidireccional de la varianza, con medidas repetidas. Se asumió una p < 0,05 para todos los análisis. Resultados: se identificó un efecto de tiempo, con valores más altos para la fuerza máxima de tracción lumbar isométrica (MILTS), luego del período de intervención en ambos grupos (p < 0.05). Sin embargo, para las otras variables investigadas, no se identificaron diferencias significativas (p > 0.05). Conclusión: La ausencia de resultados significativos para todas las variables, excepto FIMTL, puede estar justificada por la adherencia moderada de los participantes a las intervenciones (~ 59% a 66%) ya que el estudio se realizó durante el período de aislamiento social (COVID-19). Sin embargo, se cree que los modelos de intervención fueron positivos en el mantenimiento de las variables estudiadas.

Resumo Introdução: Os efeitos do taping patelar de McConnell (TPM) para o controle postural de mulheres com síndrome da dor patelofemoral (SDPF) são controversos. Objetivo: Avaliar os efeitos do TPM no controle postural estático unipodal e agachamento unipodal em mulheres com SDPF. Método: O estudo é um ensaio clínico randomizado-cego, que avaliou 40 mulheres com SDPF, e idade entre 18 e 35 anos. A amostra foi randomizada em dois grupos: grupo taping patelar de McConnell (GTPM) e grupo placebo (GP). Avaliou-se o controle postural em apoio estático e agachamento unipodal, no membro inferior com SDPF. O deslocamento do centro de pressão (CoP) foi registrado por plataforma de força, e analisado com os testes ANOVA two way e tamanho do efeito (Cohen’s d). Resultados: O controle postural estático não apontou diferenças significativas entre os grupos, tempos ou interação (P> 0,05); com pequeno tamanho de efeito. O controle postural em agachamento unipodal apresentou menor oscilação do centro de pressão para os dois grupos, com diferenças significativas em relação ao tempo de intervenção. No entanto, somente o GTPM demonstrou grande tamanho de efeito na frequência de oscilação e médio tamanho de efeito na velocidade de oscilação, durante o agachamento unipodal. Conclusão: O TPM e o placebo melhoraram o controle postural durante o agachamento unipodal. Deve-se observar que as mudanças e os tamanhos de efeito determinados para o GTPM foram significativamente maiores em relação ao GP, enfatizando sua importância clínica no tratamento de indivíduos com SDPF, durante atividades dinâmicas.

Abstract Introduction: The effects of McConnell patellar taping on the postural control of women with patellofemoral pain syndrome (PFPS) are controversial. Objective: To evaluate the effects of McConnell patellar taping on the static one-leg stance postural control and during squatting in women with PFPS. Method: A randomized, blinded clinical trial that comprised 40 women with PFPS, aged between 18 and 35 years. The study sample was allocated to two groups: McConnell patellar taping group (MPTG) and Placebo taping group (PTG). The analysis included the one-leg static support and squat on the lower limb with PFPS. The center of pressure (CoP) displacement parameters recorded by a force platform were analyzed using two-way ANOVA and Cohen’s d. Results: For the static postural control, no significant differences were found between the groups in terms of time or interaction (p>0.05); with small effect size. For the postural control during the one-leg squat, significant differences were found regarding the time of intervention for both groups, with reduced CoP parameters after the application of taping. However, the MPTG demonstrated a large effect size in frequency of oscillation and medium effect size in speed of oscillation, both during the squat exercise. Conclusion: McConnell patellar taping and placebo taping improved postural control during the one-leg squat. It should be observed that the changes and effect sizes determined for the MPTG were significantly higher compared to the PTG, emphasizing its clinical importance in the treatment of individuals with PFPS, during dynamic activities.
