Abstract：26 untrained colege students were recruited andrandomlydivided into the whey protein group （P group） and the placebo group（C group）.Both groupsunderwent 8-week，4-times-per-week，moderate-to-high-intensity resistance training.The subjects ensured consistent diet before and after the intervention.Immediately after training in the P group， 300mL ofPuko Ultra Protein Drink wassupplemented; in the C group，an equal amount of maltodextrin was supplemented.Before andafterthe intervention，tests were conducted：skeletal muscle mass，1RMof squat/lung press，relative peak torqueofflexor/extensor muscles，and fasting blood samples werecollectedbefore，2hoursafter， and 24 hoursaftertheexercise，totestT-AA，IL-6，andIL-1O.Theresultsshowthataftertheintervention，themale participants intheP group have significantly higher skeletal muscle massandrelativepeak torqueofflexor/extensor muscles than those in the C group （P<0.05） ;the1RMof squat/lung press increases significantly（ P<0.01 ）;T-AA increases significantlyat rest，2 hours after exercise，and 24 hours after exercise （ P <0.01）; IL-10 increases significantly 24 hours after exercise compared to the resting state （ P <0.05）.The female participants in the P group have significantly lowerbody fat percentage than those in the C group （ P <0.05）;the 1RMof squat increases significantly （ P <0.01）; the relative peak torque of extensor muscles increases significantly（ P <0.05）.The research conclusion is that during the （20 8- week resistance training period，supplementing with liquid whey proteincan improve protein metabolism toacertain extent，significantly increaseskeletal musclemass and musclestrength，reduce bodyfat percentage，andenhance the body's anti-inflammatory ability and immune function.
