PHILADELPHIA — Striker Jordan Morris opened an app on his smartphone the other day. With a few flicks of his thumb, panels related to his heart, kidney and liver functions, along with a reading of his electrolytes and vital signs, appeared on the display. Assessments were coded in the greens and oranges and reds of a traffic light.

The recent explosion of analytics and wearable technology in soccer has expanded to biotech for the United States men’s national team, which will face Jamaica on Wednesday in the final of the regional Gold Cup in Santa Clara, Calif.

Since January, about 30 players from the men’s national team pool — and 50 to 60 from the women’s pool — have had sophisticated blood analysis.

The screenings can be used to help determine the overall health of the players and can help answer health-related questions, including whether they have anemia, high cholesterol or high blood pressure of which they were unaware. But the analysis of biological markers is also meant to aid in performance, recovery and injury prevention by identifying certain vitamin and mineral deficiencies that could be improved with changes in diet and lifestyle and the use of nutritional supplements.
