Why did the group of Dr. Desai from Cleveland Clinic in Ohio choose different journals to publish their two papers about sports watch accuracy validation?

What made cardiologists who published a first paper in Medicine & Science in Sports & Exercise, which was founded in 1969:

https://journals.lww.com/acsm-msse/Fulltext/2017/08000/Variable_Accuracy_of_Wearable_Heart_Rate_Monitors.22.aspx

publish their second paper about sports watch accuracy validation in Cardiovascular Diagnosis and Therapy, a journal which was founded in 2011. Is the older journal not the better journal?

Did they submit the second paper also to Medicine & Science in Sports & Exercise first, and was it rejected there, since they have chosen a treadmill protocol with speeds only up to 15/km/h, which is strange. Did they had problems with ECG movement artifacts at higher speeds, and did not choose higher speeds for that reason? Did they decide not to change the treadmill protocol and to submit it to Cardiovascular Diagnosis and Therapy instead?
