Learn about the benefits of muscle strength training combined with tai chi for adult skeletal muscle in multiple CT scanning. The study included 182 people over the age of 60 with no long-term history of physical activity and exercise. They were divided into the Taijiquan group (52 people), student muscle strength group (45 people), student muscle group combined with Taijiquan group (45 people), and control group (40 people). The board of directors did not attend. The other three groups received tai chi (more than 4 times a week), muscle strength training, and muscle training combined with tai chi for 6 months. Lumbar spine (L1-4) BMD and Berg scores were approximately the same as those measured in adults before exercise and at 3 and 6 months after exercise. The results showed that there were significant differences in the scores of lumbar spine BMD and Berg Balance Scale between the Taijiquan group and students before and after exercise combined with muscle strength training ( P < 0.05 or <0.01). The difference was statistically significant ( P < 0.05 ). The scores of lumbar BMD and Berg Balance Scale in the core muscle strength training combined with Taijiquan group after 6 months of exercise were higher than those after 3 months of exercise ( P < 0.05 ), and the CT value of lumbar vertebral bone calcium was significantly positively correlated with BMD (Pearson correlation coefficients of L5 vertebral body were r = 0.704 , 0.683, 0.728, 0.673, and 0.686, P < 0.01 ). Single or combined training of core muscle strength or Taijiquan can improve lumbar bone mineral density and balance function in the elderly.

The pristine epoxy resin exhibited its low fracture toughness and low thermal stability. The using of functionalized liquid rubber led to an improvement of fracture toughness along with a reduction of thermal stability of epoxy resin. So to simultaneously improve both the fracture toughness and the thermal stability of epoxy resin the silica/PANI core-shell particles have been used as an additive. The core/shell particles were prepared by decorating the surface of silica with polyaniline via a chemical oxidation reaction. The silica was extracted from rice husk via some simple steps. The high-speed mechanical stirring was utilized to enhance the uniform dispersion of core/shell particles in epoxy resin. The nanocomposite was formed at room temperature using DETA as a curing agent. The mechanical characteristics and thermal stability of nanocomposite were examined including tensile strength, exural strength, fracture toughness, and TGA. The tensile strength was improved by 16,16% from 40,9 MPa to 47,51 MPa by adding core/shell particles to epoxy resin. The thermal stability of epoxy resin was also improved with presence of core/shell particles. In particular, the fracture toughness was improved by 52,8% from 1,12 MPa.m − 1/2 to 1,87 MPa.m − 1/2 . The electrical conductivity of epoxy resin with SiO 2 @PANI Core/Shell increased by 178 times when compared with pristine epoxy. The SEM image was also used to provide the evidence for the improvement in fracture toughness, and mechanism.
