Key result
Bleeding of 10% of blood volume initially increased upright and exercise pulse rates and decreased physical working capacity, with recovery by day six and further increase after reinfusion.
Why the study?
Does bleeding and subsequent reinfusion of 10% blood volume affect pulse rate and physical working capacity in male subjects?
Population
6 male subjects
Comparison

Acute hypovolemia may raise upright/exercise heart rate and lower capacity; leaves open relevance to modern donation or training protocols.
Does bleeding and subsequent reinfusion of 10% blood volume affect pulse rate and physical working capacity in male subjects?
Acute blood loss of 10% transiently increases pulse rate and decreases physical working capacity, with physiological overcompensation observed by day 6.
GULLBRING et al. (1960) studied this question. Bleeding and reinfusion vs. Baseline was evaluated on Pulse rate at rest and during exercise, and physical working capacity (PWC 170). Bleeding of 10% of blood volume initially increased upright and exercise pulse rates and decreased physical working capacity, with recovery by day six and further increase after reinfusion.
