2.1. Effect of CE Supplementation on Forelimb Grip Strength
Absolute grip strength was lower for vehicle- than CE-treated groups (all p < 0.005; Figure 1A). Previous study has shown a positive correlation between grip strength and anthropometric factors such as age, weight, body mass index and waist circumference [17]. Therefore, we divided grip strength by BW for relative grip strength and still found lower grip strength for vehicle- than CE-treated groups (Figure 1B). For the trend analysis, absolute and relative grip strength dose-dependently increased with CE supplementation (p = 0.0004 and p < 0.0001, respectively).
