The purpose of this study was to compare muscle activity of lower extremity muscle and erector spine muscle between ankle joint neutral position and plantar flexion position. The muscle activity of the vastus medialis oblique, vastus lateralis, biceps femoris, and erector spinae were measured according to the two positions of ankle joint neutral position and ankle joint plantar flexion during squat exercise in 20 normal adults. The muscle activity of the vastus medialis oblique, vastus lateralis, biceps femoris, and erector spainae were significantly different according to the position of the ankle joint during squat exercise (p <.05). In the vastus medialis oblique, the ankle plantar flexion showed higher muscle activity than the ankle joint neutral position (73.9% of MVIC vs. 78.8 of MVIC). Ankle joint neutrality showed higher muscle activity than ankle joint flexion in the vastus lateralis, biceps femoris, and erector spinae (75.1% of MVIC vs. 69.4% of MVIC; 7.7% of MVIC vs. 6.7% of MVIC; 25.9% of MVIC vs. 21.9% of MVIC, respectively). The plantar flexion of the ankle joint during squat exercise is a more effective way to strengthen the vastus medialis oblique, but it is less effective than the ankle joint neutral position for strengthening the vastus lateralis, biceps femoris, and erector spinae.

In this animal experiment, we examined the influence of Gastrodia elata water extract (GEE) against metabolic variations in high-fat diet (HFD)-induced obesity in C57BL/6 mice. Mice were nourishing with a normal diet (control), high-fat diet (HFD), HFD + GEE 100 mg/kg body weight (b.wt.)/day, HFD + GEE 200 mg/kg b.wt./day, and HFD + GEE 500 mg/kg b.wt./day for 8 weeks. The GEE (100, 200, and 500 mg/kg)-treated animals exhibited substantial decreases in body mass, fat mass, adipocyte hypertrophy, and epididymal white adipose tissue (eWAT) collate to the HFD-fed group. Furthermore, GEE treatment significantly inhibited adipogenesis in the GEE group by reducing the mRNA expression of sterol regulatory element-binding protein1 (SREBP1), fatty acid synthase (FAS), CCAAT/ enhancer binding protein (C/EBP)-α, peroxisome proliferator-activated receptor (PPAR)-γ, and tumor necrosis factor (TNF)-α agreeing to the HFD-fed animals. These research outcomes recommend that GEE is possibly valuable for the prevention of HFD-induced obesity via modification of various pathways related with adipogenesis and food consumption.
