Finger Length and Height May Predict Lactate Levels in Women’s Football
Updated June 11, 2025
As the 2025 Euros approach, a new study from Swansea University explores the connection between physical attributes and lactate production in female professional footballers. Lactate, a key fuel for nerve and muscle cells, increases during intense exercise. However, excessive lactate can signal bodily stress.
Scientists are investigating whether finger length and height can predict lactate production. The ratio between index and ring fingers (2D:4D) has previously been linked to endurance, heart attack risk and COVID-19 severity.
Professor John Manning, from Swansea’s Applied Sports, technology, Exercise and Medicine (A-STEM) research team, collaborated wiht researchers in Cyprus, Poland and Spain. They monitored male and female professional footballers, finding rapid lactate accumulation during treadmill tests at speeds up to 16 kilometers per hour.
The latest findings, published in Early Human Development, focus on female players, following a prior study on male players. Some footballers showed minimal lactate increases, while others experienced rapid rises.
In men, the digit ratio (2D:4D) proved the strongest predictor of lactate.For women, height and 2D:4D were key indicators.
Men with a long ring finger relative to their index finger produced little in the way of lactate. For women, there were two predictors, height and 2D:4D. Lactate levels were low for tall women and women with a long ring finger relative to their index finger. The link here is thought to be testosterone-oestrogen balance in the womb and at puberty.
A longer ring finger suggests higher prenatal testosterone, while a longer index finger indicates higher prenatal estrogen. men generally have longer ring fingers than women, while women tend to have longer index fingers than men.
Manning explained that individuals exposed to high testosterone and low estrogen levels before birth (long ring fingers) and at puberty (tall women) exhibited lower lactate levels during treadmill tests.
These results have implications beyond football — in sports including distance running as well as in clinical settings in which high lactate is found in serious medical conditions such as following heart attack.
Manning’s previous work has explored the relationship between 2D:4D and fertility,health and behavior. His recent research also examined the connection between digit ratio and oxygen consumption in footballers, as well as the link between finger length and drinking habits.
What’s next
Future research may explore how these findings can be applied to training regimens and injury prevention strategies for both male and female athletes, as well as potential applications in clinical settings.
