Plasma Nucleotide Dynamics during Exercise and Recovery in Highly Trained Athletes and Recreationally Active Individuals

Figure 2

Venous plasma ATP concentration per kilogram of skeletal muscle mass () before, during, and after incremental treadmill test until exhaustion in sprinters (n=11), futsal players (n=14), endurance athletes (n=16), and control group (n=12). Data are means ± SD. Arrows indicate the first significant differences from samples taken at rest and maximal exercise within groups. Significant differences between blood sampling points: , . Significant differences between groups at the same measurement point: , ‡, †.
