Interventions
Behavioral : 1. Exercise intervenions: ? The isometric leg extension and isometric handgrip exercises used in this study will perform 4 sets for 2 minutes (8 minutes in total) with 30~50%
of the maximal voluntary contraction. And, the rest time for each set will be 1 minute ? The isometric squat will perform 4sets for for 2 minutes (8 minutes in total) at the angle determined by the in
of the heart rate reserve on the designated track. All exercise interventions will be conducted in a 1:1 match with one person.
2. Measurement items : The items to be measured will be classified into
