Acute and chronic effects of Rhaponticum carthamoides and Rhodiola rosea extracts supplementation coupled to resistance exercise on muscle protein synthesis and mechanical power in rats

Figures & data

Table 1 Human equivalent doses (HEDs) administered to the different groups of animals in the acute study

Table 2 Human equivalent doses (HEDs) used to feed the different groups of animals in the chronic study

Fig. 1 Effects of Rhaponticum and Rhodiola extracts on protein synthesis. Quantitative analysis of puromycin incorporation in total muscle protein extracts of FDP (a), deltoid (b) and biceps muscles (c) following acute resistance exercise. Graphs show the level of puromycin incorporation compared to the control (CTL) group. *, p < 0.05; * *, p < 0.005

Fig. 2 Effects of chronic Rhaponticum and Rhodiola extract treatments associated with exercise on body weight. Total mass was assessed before and after the chronic protocol

Fig. 3 Effects of chronic Rhaponticum and Rhodiola extract treatments associated with exercise on muscle mass. Masses of FDP (a), deltoid (b) and biceps muscles (c) are normalized to total body weight. *: p < 0.05 compared to the CTL group

Fig. 4 Effects of chronic Rhaponticum and Rhodiola extract treatments associated with exercise on physical performance. The graphs show the mean delta power between pre-training and post-training in each treatment group (a), and for the 1-RM test (b). *: p < 0.05 compared to the CTL group. $: p < 0.05 compared to the Rho group

Fig. 5 Effects of chronic Rhaponticum and Rhodiola extract treatments associated with exercise on muscle fibers (FDP muscle). The mean cross-sectional area of FDP muscle is presented in (a). The ratio of type I/type II fibers was evaluated (b)
