I don’t recall any mention of other Vulcan female strength in the series, so it may not just be T’Pol.

Quick Google search so don’t blast me if it’s incorrect. “A study in the Journal of Applied Physiology found that men had an average of 26 lbs. (12 kilograms) more skeletal muscle mass than women. Women also exhibited about 40 percent less upper-body strength and 33 percent less lower-body strength, on average, the study found”

Even if the ratios were the same, which we have no reason to assume they would be, the multiplicative effect would make a Vulcan woman much less opposing. She is also a scientist and not a soldier from a race that abhors violence.

Don’t get me wrong, I like that they make Klingon women equals in battle. I love that the Orion’s are secretly ran by women. I’m not going to chalk this one up to blatant sexism (nor will I ignore the fact that it could be).
