Shallow water walking (SWW) generates changes in cardiorespiratory parameters in comparison to terrestrial exercise, and these changes are highly dependent of immersion depth. We reviewed the evidence from observational studies focusing on physiological and biomechanical responses of SWW in comparison to dry land walking. This systematic review and meta-analysis (initial search: 1516 studies; systematic review: 40 studies; meta-analysis: 22 studies) presents evidence that higher energy expenditure, heart rate and rating of perceived exertion are accompanied by depth-dependent reductions in self-selected speed and stride length in SWW compared with dry land. The stride frequency, however, was similar at waist and reduced at xiphoid depth. As expected, the ground reaction forces were reduced according to the buoyance forces acting. SWW appears to increases muscular activity. Importantly, the depth-related increase in energy expenditure of SWW seems to involve a major role of resistive forces compensating the reduced task of support the body weight. Besides the benefits of water immersion as reduced joint impact and safety, biomechanical alterations on force production may produce additional long-term gains in functional mobility. However, the influence of these physiological and biomechanical alterations on functional mobility are largely unknown. Due to these inconclusive points, there is a huge opportunity to determine (1) the alterations on muscle activation in different depths in order to explain the higher energy expenditure at organismal level, and (2) whether these alterations can maximize gains in metabolic economy and gait biomechanics after long-term SWW intervention.

Abstract. Backgrounds: Central obesity, as a pivotal component of metabolic syndrome is associated with numerous co-morbidities. Dietary factors influence central obesity by increased inflammatory status. However, recent studies didn’t evaluate the association between central obesity and dietary inflammation index (DII®) that give score to dietary factors according to their inflammatory potential. In the current systematic review and meta-analysis, we summarized the studies that investigated the association between DII® with central obesity indices in the general populations. Methods: In a systematic search from PubMed, SCOPUS, Web of Sciences and Cochrane electronic databases, we collected relevant studies written in English and published until 30 October 2019. The population of included studies were apparently healthy subjects or individuals with obesity or obesity-related diseases. Observational studies that evaluated the association between DII® and indices of central obesity including WC or WHR were included. Results: Totally thirty-two studies were included; thirty studies were cross-sectional and two were cohort studies with 103071 participants. Meta-analysis of observational studies showed that higher DII® scores were associated with 1.81 cm increase in WC (Pooled weighted mean difference (WMD) = 1.813; CI: 0.785–2.841; p = 0.001). Also, a non-significant increase in the odds of having higher WC (OR = 1.162; CI: 0.95–1.43; p = 0.154) in the highest DII category was also observed. In subgroup analysis, the continent, dietary assessment tool and gender were the heterogeneity sources. Conclusion: The findings proposed that adherence to diets with high DII® scores was associated with increased WC. Further studies with interventional designs are necessary to elucidate the causality inference between DII® and central obesity indices.
