Effects of Training on Running Cost and Aerobic Capacity in Individuals with Obesity
This study investigated running cost (CRun), peak oxygen consumption
(V̇ O2peak), and ventilatory threshold (VT1)
responses to exercise programs for individuals with obesity. Ninety-four
individuals (38.2±7.7 years;
33.4±2.9 kg/m²) were assigned into strength
(n=24), endurance (n=26), combined (n=22), and physical
activity (control, n=22) groups for 22 weeks, plus diet recommendation.
The V̇ O2peak, VT1, and CRun were
assessed through a maximal incremental step test. The change of V̇
O2peak in combined (9.9%) differed from the other groups,
with lower values in women than men (0.7% vs. 6.2%). The
VT1 change in combined (16.4%) differed from the strength
(4.9%) and physical activity (1.2%) groups, with the change in
endurance (12.7%) also being higher than the physical activity group.
Only men in the combined group increased absolute V̇ O2peak,
while both sexes increased VT1 in the endurance and combined groups.
No effects for groups and sex were significant for CRun in moderate
(<VT1) or high-intensity (>VT1)
running zones, despite CRun changes in <VT1 and
>VT1 zones correlated with the alterations of V̇
O2peak and VT1 (r²=0.29–0.59).
Therefore, moderate aerobic exercise stimulus is suitable for VT1
improvement in individuals...
