Figure 5. Indirect calorimetry, endurance, and grip strength. (A) Day and night values for VO2, (B) respiratory exchange ratio, (C) energy expenditure, and (D) activity are shown for MuGHRKO (black bars) and controls (white bars) for males and females. (E) Treadmill endurance and (F) forelimb grip strength values are shown for MuGHRKO and controls. All values are represented as mean + SEM (n=6-8 per group per sex).
