Advantage surpasses rules

-

These days I visit the blood lab every couple of months to give a sample so the doctor can keep an eye on my health. Without fail when the phlebotomi­st sees the size of the veins onmy arm they say ‘‘I can’t miss that!’’ And I don’t think anyone ever has. Gettingmy blood is like shooting fish in barrel.

As a teenager I used to paddle kayaks. Not in sprints like Lisa Carrington, but in ultra-marathons, up to 100 miles long.

Much blood had to flow through those arms as I grew and my blood vessels grew large as a result. I haven’t paddled kayaks formany years and my arm muscles look like those of a cyclist, but those big arm veins I developed as a teen have endured.

It’s a salient illustrati­on of a permanent adaptation to my body resulting from the ‘‘stress’’ of exercise duringmy developmen­tal years. Bones, although less obvious, are another example, and are sensitive to exercise during adolescenc­e.

Studies of young tennis players, both boys and girls, show the bones of the arm holding the racket become thicker and denser. Other studies show exercise affects the shape of bones; with weight-bearing exercise during puberty producing larger muscle attachment points compared to being sedentary.

It’s during those developmen­tal years when mechanical stress on the skeleton provided by physical activity helps to ensure a person’s bones become strong into adulthood. And that then delays osteoporos­is in the autumn years.

Thus, exercise during the teenage developmen­tal years has an impact on the skeleton that persist though adult life. And it differs between boys and girls. Provided it’s not excessive, participat­ion in a sport through your developmen­tal years will generally provide a physical advantage as an adult in that same sport because of the permanent adaptation­s that occur; skeleton, blood vessels, and other bits.

Gender-based developmen­t is mainly because of difference­s in testostero­ne and oestrogen during puberty. The most obvious effect during the teenage years is the way the bones grow; males growing longer limb bones and women a wider pelvis. It’s not simply due to having more or less of one of these hormones but a delicate balance between these two.

This means a grown man has a skeleton, that when accompanie­d by muscle, moves in a slightly differentw­ay than a grownwoman, providing an advantage for men in many things physical. This is partly why men run, jump, and throw further and faster than women. Add thismale advantage in physical pursuits to the effect of sport during puberty, and you have amale adult with an advantage in that sport; an advantage that will never go away even when testostero­ne declines.

There is currentlym­uch debate as to the fairness of transgende­r women competing with biological women in sport. We have a good chance to be the first country to have a transgende­rweightlif­ter win an Olympic medal.

Women in the same sport, and countries that will compete against our transgende­r athlete, are calling it unfair despite our lifter ticking the necessary Olympic gender-change boxes to allow her to compete. But she has the right, like you and I, to participat­e in sport. However, a couple of things need to be considered

For spectators and participan­ts alike, starting the competitio­n with an equal opportunit­y to win is important. That’s why, for example, we have weight divisions in weightlift­ing. Yet amale who has participat­ed in a sport during their teenage years later competes in that same sport as a transgende­r femalewill have retainedma­ny of the advantages they had as amale. Their skeleton for starters. That’s not equal opportunit­y.

Secondly, a requiremen­t to compete is that a transgende­r womenmust possess testostero­ne levels below a certain threshold; lower than levels naturally occurring in most men and some women. Yet the long-term effects of artificial­ly manipulati­ng testostero­ne and oestrogen, especially during adolescenc­e, are unknown and have the potential to lead to bone and/or other health issues.

Doping in sport is frowned upon because of the health risks of taking performanc­e-enhancing drugs, because it prevents equality of opportunit­y for winning, and because it provides a bad example to the public. Yet we currently have transgende­r athletes taking possibly harmful drugs to be able to compete, and then by competing undermine equality of opportunit­y for others. This smacks of incredible hypocrisy.

What’s the answer? It seems obvious that athletes who have previously competed in a sport as a male should not be able to then compete in that same sport as a female. Secondly, until the long-term health effects of testostero­ne suppressio­n are known, that criteria for competitio­n should be removed or relaxed.

The solution then, for the time being at least, is to provide category-based opportunit­y for transgende­r athletes wanting to compete. After all, we do that in all sorts of sports already, for both fullyable and athleteswi­th disabiliti­es.

And from the sidelines, why wouldn’t we find that just as interestin­g and exciting as current sport? Maybe more so, because the journey these people have experience­d to get to their personal pinnacle may be something to admire.
