Carl,
I agree with your call, but would first ask some basic questions:
Shoes? Surface? prior conditioning and jumping leading up to the day?
Hard surface, bad footwear, too many jumps? HJ torque from poor angles at plant, and adaption to curve running?
(tight approach curve may be mis-perscribed?)
And as far as the previous training and jumping in specific, connectative tissues adapt to workload over time. So, say a basketball player or track man that has been working out over a period of time and develops pain is a whole different story than one who say ate donuts all winter and just came out for spring track and took 30 full jumps the 3rd day into the grand experiment!
Hardwo
What was different about the day that resulted in the pain?
