When to use this
When you coach jumpers who train explosive and eat light, or before an all-day meet with long gaps between attempts.
- A jumper looks springy in the opening rounds and flat by finals, and the snack bag was empty all day.
- Lightness talk is creeping into the jumps group and bone health is not part of the conversation.
- Planning what jumpers should pack for a meet where attempts sit hours apart.

How to think about weight pressure in the jumps
This section holds no deficit, rate, or body-fat targets on purpose. What it gates is the decision framework, because for a growing athlete the thinking is the protocol.
Unexplained fatigue, recurring injuries, missed cycles, or sudden weight loss are stop signs, not discipline. Involve a physician and sports dietitian immediately, and never praise rapid weight loss.
