Abstract: The present disclosure relates to a complex probiotic composition and a method for improving exercise performance of a subject with low intrinsic aerobic exercise capacity. The complex probiotic composition, which includes Lactobacillus rhamnosus GKLC1, Bifidobacterium lactis GKK24 and Clostridium butyricum GKB7, administered to the subject with the low intrinsic aerobic exercise capacity in a continuation period, can effectively reduce serum lactic acid and serum urea nitrogen after aerobic exercise, reduce proportion of offal fat and/or increase liver and muscle glycogen contents, thereby being as an effective ingredient for preparation of various compositions.

Abstract: A socket wrench includes a handle having a housing and a grip portion, a drive shank having a ratchet wheel mounted in the housing, two pawl members engaged with the ratchet wheel, a switching member located between the pawl members, two elastic members each biased between the housing and the respective pawl member, a control knob connected with the switching member, a driven arm having a mounting sleeve and an arcuate mounting slot, a connecting plate provided on the handle, and two driving arms provided on the connecting plate and received in the mounting slot. When in use, one of the driving arms drives the driven arm by a leverage to drive the drive shank to rotate a socket so as to operate a workpiece in an energy-saving manner.
