Abstract: A portable training device for plantar core muscles includes: a supporting portion corresponding in position to a transverse arch of a human sole and having a supporting-portion thickness and an allowable deformation in a Z direction; an inner cushioning portion connected to the supporting portion, corresponding in position to a first metatarsophalangeal joint of the sole, and having an inner-cushioning-portion thickness in the Z direction; and an outer cushioning portion connected to the supporting portion, corresponding in position to a fifth metatarsophalangeal joint of the sole, and having an outer-cushioning-portion thickness in the Z direction. The supporting-portion thickness is greater than the inner- and the outer-cushioning-portion thicknesses. When the portable training device is stepped on with the sole, the supporting portion supports the transverse arch to help train a longitudinal arch of the sole to arch naturally, thereby guiding the plantar core muscles into contraction to strength those muscles.

Abstract: A wearable stimulation device includes a wearable member, a stimulation unit, and a driver. The stimulation unit is secured to the wearable member. The stimulation unit includes an immovable end, a stimulation end, and a power element. The power element is connected between the immovable end and the stimulation end for driving the stimulation end to reciprocate relative to the immovable end. The driver is in signal connection with the power element. The driver is configured to output a vibration signal to the power element for the stimulation end to have a stroke of between 8.8 mm and 10.8 mm, a thrust of between 5.6 N and 7.6 N and a reciprocating frequency of between 180 Hz and 220 Hz, thereby stimulating the deep muscles of the abdomen or waist of a human body without affecting the superficial muscles.
