N2 - This work sought to determine the fi tness
responses and energy expenditure (EE) following
once-weekly hill climbing for 16 weeks on diff erent
slopes. A cohort of 98 healthy, sedentary subjects
(49 female, 49 male) completed the program
at their preferred climbing pace. Body composition,
resting metabolic rate (RMR) and VO 2 max
were measured. EE was measured on 4 slopes
(11.6 °, 19.9 °, 14.9 °, and 28.6 °) at the subjects’
preferred speed. In males, weight, body mass
index, fat mass signifi cantly decreased (P < 0.05),
and RMR showed an increasing trend, but the difference
was not signifi cant (P = 0.051). In females,
the muscle mass increased signifi cantly, and fat
( %) and fat mass signifi cantly decreased (P < 0.05).
Absolute and relative of VO 2 max, ventilation (VE)
improved signifi cantly in both sexes (P < 0.01).
Energy expenditure was similar on diff erent
slopes, but shows gender-specifi c values of
approximately 50.4 and 33.6 kJ/min for males
and females, respectively. The regression equation
of EE (kJ/min) = [1.724 × (female = 1, and male
= 2) + ( − 0.072 × age) + 0.106 × weight + 0.024 ×
HR + 0.136 × slope + 1.487 × velocity] × 4.2. In conclusion,
hill climbing at a subjects’ preferred
velocity is a vigorous-intensity physical activity
for energy cost and, performed once weekly,
enhances cardiorespiratory fi tness and reduces
fat mass, therefore making it a viable exercise for
most people.
