ABSTRACT
BACKGROUND: Nordic walking (NW) is a potentially beneficial exercise strategy for overweight and obese people. To date, no reviews have synthesized the existing scientific evidence regarding the effects of NW on this population. This systematic review and meta-analysis aimed to identify the characteristics, methodological quality, and results of the investigations that have studied the effects of NW in overweight and obese individuals. METHODS: Six electronic databases were searched up to June 2019 for studies that examined the effects of NW on people with a body mass index ≥ 25 kg/m2. The methodological quality of the included randomized controlled trials was retrieved from the physiotherapy evidence database or evaluated using the physiotherapy evidence database scale. RESULTS: Twelve studies were included in the review. The investigations were mostly good-to-fair methodological quality. NW groups had a significant improvement on parameters such as fasting plasma glucose, abdominal adiposity, and body fat compared with the baseline, but no significant improvements were found when compared with control groups. CONCLUSIONS: NW can potentially lead to improvements in parameters related to major health outcomes in overweight and obese people. The lack of control for confounding variables in the analyzed studies prevents further elaboration on its potential benefits.

El objetivo de este trabajo es evaluar las propiedades contráctiles de los músculos erector spinae (extensor del tronco), rectus abdominis, y obliques externus (flexor del tronco) en mujeres jóvenes físicamente activas, utilizando una técnica novedosa como es la tensiomiografía (TMG). La muestra estuvo compuesta de 5 mujeres jóvenes, físicamente activas y en un estado saludable. Se ha realizado un análisis descriptivo, una comparación de medias, mediante la prueba de Wilcoxon, y el test de Kruskal-Wallis. Los resultados muestran que existen diferencias significativas entre los tres músculos evaluados, pero no se han encontrado diferencias significativas entre los lados derecho e izquierdo, ni entre las participantes de este estudio. En conclusión, la TMG permite obtener un patrón de respuesta muscular para cada uno de los músculos evaluados (AU)
The aim of this study is to evaluate the contractile properties of erector spinae muscles (extensor of the trunk), rectus abdominis and obliques externus (flexor of the trunk) in physically active young women, using an innovative technique such as the tensiomyography (TMG). The sample consisted of 5 young women, physically active and in a healthy condition. It was carried out a descriptive analysis, a comparison of averages by means of Wilcoxon test and Kruskal-Wallis test. The results show significant differences among the three muscles tested, but it wasn´t found significant differences among left and right sides or among the participants in this study. In conclusion, the TMG allows obtaining a muscular response pattern for each of the muscles evaluated (AU)
