Description
Denisse Bustos and co-authors profile, in 2026, the fitness of volunteer firefighters on a treadmill test. Thirty-one men ran in steps that rose in speed, with short rests between. Breath, heart rate, energy use, and blood lactate were tracked from start to after the test. Fire work demands high fitness, so the team checked men against guidance from a national fire body.
Oxygen use and heart rate climbed steeply as speed rose. The share of energy from oxygen fell while the burn-without-oxygen share grew. About half the men missed the oxygen mark advised for their age. Heavier men showed lower heart rates at hard stages, a pattern the authors flag. They urge set training and food guidance.
