Jump-Rope-Cord-Flexibility

How does the weight, thickness, length, and handle type make a jump rope ‘just right’?

In this three-part series Dr. Obrecht explains what makes a jump rope just right from the scientific perspective of a Ph.D. Physicist.  In Part 1 of 3: The Cord, we learn about the variety of jump rope cords, and how careful selection can lead us to a better jumping experience.  In Part 2 of 3: The Size, we learn about how to become efficient in jumping by choosing the proper cord size.  Finally, in Part 3 of 3: The Handle, we learn about the most important part of the jump rope, namely the handle technology that makes your rope turn efficiently.

What makes our jump rope handles spin so efficiently and how can you get your handles to spin that long?  It’s quite an art!  Our staff scientist, Johnny, explains!
