Physical exercise program carried out in primary health care units improves exercise tolerance and economy of movement
MetadataShow full item record
The purpose of this study was to evaluate the effect of a 1 yr exercise program carried out in Primary Health Care Units (PHCU) concerning the variables related to cardiorespiratory fitness (CF). A quasi-experimental study was performed with 22 women (56.35 ± 9.25 yrs old). The intervention was comprised of 3, 90-min sessions·wk-1. The subjects' CF was measured via submaximal incremental treadmill test through indirect calorimetry. A significant difference in the subjects' final exercise time (in minutes) was found between the initial test and the 1 yr test [Baseline (BL) = 6.36 ± 3.2 and at 1 yr (1Y) = 10.80 ± 5.0 min; P = 0.004] and final exercise stage (BL = 2.2 ± 1.2 and 1Y = 3.6 ± 1.7, P = 0.004). The number of completed minutes and stages during the treadmill test was significantly increased after the 1 yr physical exercise program carried out in the PHCU. Thus, the subjects' exercise tolerance and economy of movement were improved.
