How to Cut Weight for Rowing — SportsFlow Research

Composite Portrait

He needs to make 72.5 kg by Saturday morning. He weighs 75 kg on Monday. He panics, cuts food to near-

starvation, and runs in garbage bags. By weigh-in he makes weight. By race time his glycogen is depleted,

his reaction time is delayed, and he races at 85% capacity. He made weight and lost the race. There is a

Gradual weight-management planning tied to competition calendar and health markers.

SECTION I

What the Research Tells Us

Koral & Bhambhani (2014) showed that rapid weight loss (>3% body mass in <72 hours) impaired rowing

performance by 5–8%, while gradual weight loss over 4–6 weeks preserved performance in lightweight rowers. The

Weight Loss Rate vs. Performance

0.5-1 LB/WK OPTIMAL

Too fast (dangerous)Too slow (ineffective)

Weight Methods

Method	Rate	Risk	Impact
Gradual	0.5-1 lb/wk	Low	Minimal
Moderate	1-2 lb/wk	Moderate	Monitor HRV
Rapid	>2 lb/wk	High	Impairment
Water	Acute	Very High	Dangerous

difference is simple: rapid cuts lose water and glycogen (performance fuel), while gradual cuts lose fat (non-

Lightweight rowing demands weight management. Doing it wrong costs health and speed.

“Making weight is a skill, not a sacrifice. Plan it over weeks, not days. Your body will thank you at the start line.”

How the Flowbase AI Coach Helps

The Flowbase AI Coach builds a week-by-week weight management plan calibrated to your competition calendar. It

tracks daily weight, adjusts caloric targets based on training load, and flags when a cut is proceeding too
