According to these studies, the average height of women is 12 cm lower than the average for men, the average weight is 10 kg less, the muscle mass is on average 20 kg less. As a percentage, the total mass of a woman is on average 20% less than that of men, the mass of muscles and skeleton is 40-45% less, the fat mass is 20-25% more. The weight without fat per centimeter of height is 0.36 kg for men, 0.26 kg for women. The size of muscle fibers in women is 35% less, the number of fibers is 14% less. The muscle mass of the upper part of the body in women is 50% less than in men, and the lower part is 30% less. Accordingly, the muscle strength of women according to isometric measurements is 50% in the upper part and 65% in the lower part relative to men. The incision area of the humerus in women is 25-35% smaller, the femur is 15% smaller. The area and volume of the vertebrae are 25-30% lower. The structure of the legs and pelvis – women have a shorter step, according to studies with an increase in the wearable load, women, unlike men, shorten the step even more, increase the duration of time when both feet are on the ground, etc., in general, when walking, increased kinetic load, which is one of the causes of increased injuries. Women also have shin bones 12% thinner and 42% lower twisting resistance.

Important parameter: bone density. In women at the age of conscription, bone density is not much lower than in men, this usually manifests itself in old age, but in general, women are three times more susceptible to osteoporosis than men, and during combat training several additional factors act at once: increased physical activity, lack of calcium and vitamin D. Therefore, women are much more susceptible to stress fractures (they are fatigue fractures - "shivrei maamats" - stress fracture) due to accumulated microtrauma. Stress fractures, especially of the feet and lower legs, are the scourge of combat soldiers, in the 80s the percentage of victims sometimes reached 30% of the draft. The problem with stress fractures for the service is that with them the soldier gets relief from physical exertion for 2-8 weeks, depending on the degree of fracture, and with a high degree and more. Therefore, this often means a write-off from the KMB or a team course. Sometimes the course can be completed later or "catch up" at the end, sometimes it is impossible for administrative reasons, sometimes a soldier is generally written off from combat service as a result. For prevention, sufficient sleep and rest are necessary, as well as sufficient intake of calcium and vitamin D – according to all these parameters, soldiers have a serious disadvantage, especially in combat. They fought against this phenomenon by forcing commanders to observe sleep hours, and by introducing more dairy products, and gradually reduced the percentage to 5-10% for men in combat troops on average, depending on the type of troops. But for women, this percentage is always much higher with equal loads, because according to any medical statistics, the female sex is the first risk factor. And in addition to dynamic load, like running and jumping, women suffer from stress fractures even due to prolonged standing, which is not observed in men. Therefore, because of the importance of this parameter, it is always particularly noted in studies.

Women have lower ability to aerobic and anaerobic loads – they have on average less heart and lung volume, heart production per unit of time is 20-25% less, hemoglobin is 10-15% lower, maximum oxygen consumption is 20-25% less. On average, women's aerobic loads are 30% lower than men's, and anaerobic ones are 25% lower. The increase in wearable weight, according to research, slows down the performance of a ten-kilometer march in women by 23-28% more than in men: rounded off, the average male soldier will walk 10 km with a maximum speed with a load of 30 kg in an hour and a half, and a woman in two hours.

There are also statistics that due to lifting weights during the service, cases of uterine prolapse are becoming more frequent among women, but since this is a comparative statistic with other women, and not with men in the same positions, it goes through a separate paragraph.
