Figure 1. Effect of Fashion watermelon juice enriched in l-citrulline (CWJ) on jump recovery on squat jump (SJ) and countermovement jump (CMJ). Different capital letters for the same beverage show significant differences between the times and different lower case letters for the same time show significant differences between beverages.

Figure 2. Effect of Fashion watermelon juice enriched in l-citrulline (CWJ) on muscle soreness at 30 min, 24 h, 48 h, and 72 h after half-marathon. Different capital letters for the same time show significant differences between beverages and different lower case letters for the same beverage show significant differences between the times.

Figure 3. Effect of Fashion watermelon juice enriched in l-citrulline (CWJ) on blood parameters such as arginine, myoglobin, ferritin, and C-reactive protein (CRP) after half-marathon. Different capital letters for the same time show significant differences between beverages and different lower case letters for the same beverage show significant differences between the times.

Figure 4. Effect of Fashion watermelon juice enriched in l-citrulline (CWJ) on blood enzymes such as glutamic-oxaloacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), lactate dehydrogenase (LDH), and creatine phosphokinase (CPK) after half-marathon. Different capital letters for the same time show significant differences between beverages and different lower case letters for the same beverage show significant differences between the times.

Figure 5. Effect of Fashion watermelon juice enriched in l-citrulline (CWJ) on blood parameters such as lactate, creatinine, uric acid, and urea after half-marathon. Different capital letters for the same time show significant differences between beverages and different lower case letters for the same beverage show significant differences between the times.
