Heart experts - is it normal to have mild global hypokinesis at 19 years old?

No. Hypokinesis simply means "hypo/too little--kinesis/movement" this is abnormal at any age. I don't know what "heart experts" have to do with it, although it is possible that heart muscle is involved. It is almost certainly due to biochemical/ electric changes in muscles or their nerve supply. You need medical advice if you have not already.

A recent heart study has revealed that I have mild global hypokinesis and moderate la dilation. Also hocm under stress. Could you explain this plz?

Thick left ventricle. You have thick left ventricular muscle. In hocm or hypertrophic cardiomyopathy you may develop some obstruction to blood flow to your aorta from the ventricle. You need to know whether you have a mitral valve leak. It can be easily with beta blockers.
Beta Blockers. Hocm (hypertrophic obstructive cardiomyopathy) under stress means that the interventricular septum in the area of the outflow tract of the left ventricle becomes thick in systole and narrows the outflow tract thus creating a pressure gradient between the apex of the ventricle and the aorta. Some patients may have a gene that enlarges that part of the septum creating a gradient at rest.
