Exercise and recovery responses of adrenal medullary neurohormones to heavy resistance exercise
Why the study?
Does heavy resistance exercise alter the response patterns of adrenal medullary neurohormones in strength-trained men?
Population
10 strength-trained men, mean age 21.7+/-0.58 yr
Comparison
Two resistance exercise protocols of equal total… vs Resting control conditions for each time point
Design
RCT, randomized order
Follow-up
240 min postexercise

Implication
Acute adrenal activation post-resistance exercise merits recovery monitoring in athletes; extends RCT data on epinephrine and peptide F dynamics.
Structured PICO
Does heavy resistance exercise alter the response patterns of adrenal medullary neurohormones in strength-trained men?
P
Population
10 strength-trained men, mean age 21.7+/-0.58 yr
I
Intervention
Two resistance exercise protocols (high force and high power) of equal total work, separated by 1 wk
C
Comparator
Resting control conditions for each time point
O
Outcome
Response patterns of adrenal medullary neurohormones (plasma lactate, epinephrine, plasma peptide F, norepinephrine) at 0, 15, and 240 min postexercisesurrogate
Heavy resistance exercise acutely activates the adrenal medulla, with prolonged recovery periods showing increased concentrations of proenkephalin fragments.
