Fig. 3. Repeated passive exercise produced changes in physiological parameters in the blood for normal mice. (A) Experimental design for treatment with passive exercise at the speed of 9 m/min for 1 hour per day for 1, 7, 14, and 21 days. Physiological parameters in the blood were analyzed with i-STAT CG4+ cartridge and the i-STAT 1 analyzer from Abbott. (B) Lactate levels measured using i-STAT CG4+ in the blood of untreated control (CON), and mice with daily 1-hour exercise for 1 day (EXE 1d), 7 days (EXE 7d), 14 days (EXE 14d), and 21 days (EXE 21d). (C) Blood pH levels of untreated CON, and mice with 1 hour exercise for 1 day (EXE 1d), 7 days (EXE 7d), 14 days (EXE 14d) and 21 days (EXE 21d). (D, E) Partial pressures of O2 (pO2, D) and saturated O2 (sO2, E) levels in the blood of untreated CON, and mice with daily 1-hour EXE 1d, EXE 7d, EXE 14d, and EXE 21d. (F-I) Partial pressures of CO2 (pCO2, F), total CO2 (TCO2, G), HCO3 (H) and base excess extra cellular fluid (BEecf, I) levels in the blood of untreated CON, and mice with daily 1-hour EXE 1d, EXE 7d, EXE 14d, and EXE 21d. Values are expressed as mean±SEM (n=6 to 15). Difference between the indicated groups at aP<0.05; bP<0.01, respectively (one-way analysis of variance followed by the Newman-Keuls test).
