The phrase is no longer limited to contexts involving entertainment; anything that undergoes a significant change for the worse that marks the start of a period of decline can be said to have "jumped the shark":
Are you ready to take flight and jump off the highest platform at the Counsilman Billingsley Aquatic Center? Jump Days is a free event that allows students to make the progression up the platforms and finally take the 33 foot plunge off of the 10M platform.

Intersession and intrasession reliability and validity of the My Jump app for measuring different jump actions in trained male and female athletes. J Strength Cond Res 30(7): 2049-2056, 2016-The purpose of this study was to analyze the concurrent validity and reliability of the iPhone app named My Jump for measuring jump height in 40-cm drop jumps (DJs), countermovement jumps (CMJs), and squat jumps (SJs). To do this, 21 male and female athletes (age, 22.1 3.6 years) completed 5 maximal DJs, CMJs, and SJs on 2 separate days, which were evaluated using a contact platform and the app My Jump, developed to calculate jump height from flight time using the high-speed video recording facility on the iPhone. A total of 630 jumps were compared using the intraclass correlation coefficient (ICC), Bland-Altman plots, Pearson's product moment correlation coefficient (r), Cronbach's alpha (α), and coefficient of variation (CV). There was almost perfect agreement between the measurement instruments for all jump height values (ICC = 0.97-0.99), with no differences between the instruments (p > 0.05; mean difference of 0.2 cm). Almost perfect correlation was observed between the measurement instruments for SJs, CMJs, and DJs (r = 0.96-0.99). My Jump showed very good within-subject reliability (α = 0.94-0.99; CV = 3.8-7.6) and interday reliability (r = 0.86-0.95) for SJs, CMJs, and DJs in all subjects. Therefore, the iPhone app named My Jump provides reliable intersession and intrasession data, as well as valid measurements for maximal jump height during fast (i.e., DJs) and slow (i.e., CMJs) stretch-shortening cycle muscle actions, and during concentric-only explosive muscle actions (i.e., SJs), in both male and female athletes in comparison with a professional contact platform.

"AMP is a no-brainer. I will never do another type of cardio. It brings jump rope to a whole new level. In-depth stats, workouts, the community, the leaderboard... it creates motivation in so many different ways. It's my best purchase of the year!"
I honestly did feel the jump rope was a little pricey when I looked into it, however it shocked me once I started to use it. I can firmly say this is one of the best investments I have made in a long time. The material is durable, the handles are fitted nice and jumping rope is becoming smoother.
If you are in-between sizes, and you're a beginner, the larger size is usually preferable because it allows more room for error. If you are more experienced, then the smaller size tends to be better. If you currently have a rope that you are comfortable jumping with, we recommend measuring your current rope, not including the handles, for a comparison.
Parking Services offers jump-starts at no cost for vehicles parked on the main campus and in our off campus residential parking lots. Note: We are unable to provide jump-starts for electric vehicles and some hybrid vehicles.
Assistance may be available after hours and on weekends. Please contact the University Police Department at (805) 893-3446 for after-hours assistance. We do our best to assist motorists whenever possible. There may be times, however, when jump-starts are not available because staff is employed at other tasks.
