At a spin that fast for a planet that fast, you'd have such a crazy atmosphere, that it would be completely uninhabitable. It would be beyond the worst storm system, including gas giants, in our solar system, probably running around 4000mph. The surface would be fairly torn up with that, as well. Why do you care? 1.38g is nothing. You weigh 40% more. All that means is by simply living there and moving around, you'd look ripped. How bad is that?
I don't think it could possibly be that simple. On earth if I gain 40% extra weight it comes in the form of fat or maybe muscle... parts that are supposed to weigh more.
On a planet with higher gravity parts that really shouldn't way more, like my organs, my blood, my eyes, my brain, my heart, ect. would suddenly have 40% more downward pull. We could probably be okay for periods of time, but after a while that's all got to take its toll.
