Abstract: Nordic Walking (NW) and Vitamin D concentration (Vit D) alone have been shown to contribute to the health and performance of elderly people. However, the interaction between these two factors has yet to be explored. In this study 42 women over 60 years of age (69.02 ± 5.56 years) were recruited and divided in two NW groups: a high-intensity interval training group (HI-NW) and a moderate-intensity continuous training group (MI-NW). Individuals from each group completed a 12-week NW training program (3 times a w… Show more

“…Moreover, we confirm that NW promotes gains at cardiovascular fitness, in upper limbs muscle strength and functional fitness [3,4,9,10]. These gains are important also in cognitive functions when NW training is performed along with vitamin D supplementation in women [3638]. These outcomes, together with our findings, suggest the NW as an advantageous training method for the improvement of the physical condition of healthy elderly people.…”

“…Interestingly, VDR is present in the brain, skeletal muscles, and in most of the cells in the human body [ 7 ]. In agreement with this, skeletal muscle strength is associated with vitamin D status [ 8 ]. The anti-inflammatory properties of vitamin D have been also demonstrated [ 9 ].…”

“…Além do consumo adequado de macronutrientes, a vitamina D tem sido associada a massa e força muscular, visto que a mesma tem efeito protetor contra a degradação muscular, mesmo àquela induzida pelo envelhecimento, e no metabolismo do cálcio e dos ossos (Mieszkowski et al, 2018;Rafiq et al, 2017). Sua forma de atuação pode se dar pela preservação celular por meio da regulação positiva da folistatina, um inibidor endógeno da miostatina que, por sua vez, promove a degeneração muscular (Aspell et al, 2019;Remelli et al, 2019).…”

“…In the authors’ opinion, one of the elements of complete rehabilitation factors is vitamin D. It has been demonstrated that vitamin D influences the expression of approximately 900 genes [5]. Moreover, vitamin D deficiency has been associated with muscle weakness, inflammation, and impaired proprioception [6,7,8,9,10]. Moreover, it has been associated with diminished citrate synthase (CS) activity and the reduced protein content of PGC-1α in the skeletal muscle of the patients with chronic low back pain [9].…”
