The aim of the study was to analyze the effect of exercise performed on an air dissipation platform compared to the same exercise on the floor in a group of healthy women.
Material and methodsIn a quasi-experimental study 14 healthy women between 20 and 25 years performed exercises under two different conditions separated by one week, one was on an air dissipation platform and another on the floor. Respiratory exchange data were collected during the two tests using an open-circuit gas analyzer. Heart rate (HR) was recorded via telemetry. Capillary blood samples (5 μl) were taken every 10 minutes during the exercises using a portable lactate analyzer. The rated perceived exertion (RPE) was recorded every 10 minutes during the exercises using the Borg scale.
ResultsThere were significant differences in mean HR variables (platform: 173.1 ± 13.6 bpm; floor: 166.7 ± 14.1 bpm; z = 1.9; P < .05), average ventilation (VE) (platform: 58 ± 8.6 L/min; floor: 54.4 ± 12.4 L/min; z = 1.7; P < .05), lactate in the 20th minute (platform: 6.9 ± 2.4 mmol/L; floor: 4.4 ± 1.9 mmol/L, z = 2.9; P < .01), 30th minute (platform: 7.1 ± 2.6 mmol/L; floor: 5.0 ± 2.3 mmol/L; z = 2.4; P < .01) and 40th (platform: 5.0 ± 1.9 mmol/L; floor: 3.6 ± 1,6 mmol/L; z = 1.9; P < .05), with no significant differences in RPE throughout the test.
ConclusionsThe intensity of exercise on the air dissipation platform with the same session of exercises is greater than that performed on the floor, with similar values in the perceived exertion.
