On average, adult males generally have stronger bodies, particularly in absolute upper-body strength, due to higher muscle mass and testosterone levels, though women often show greater relative strength (per body mass/lean mass) in the lower body, with strength differences shrinking when adjusted for muscle size. Men typically have more muscle mass and larger, denser bones, while women have more body fat, with these biological factors contributing significantly to overall strength disparities.
Males have on average 75% more upper body muscle mass than females, which corresponds to 90% greater upper body strength. Men have 50% more lower body muscle mass then women, which corresponds to 65% more lower body strength.
Biological sex is a determinant of athletic performance: adult males are faster, stronger, more powerful than females because of fundamental sex differences in anatomy and physiology dictated by sex chromosomes. Before puberty, sex differences in athletic performance are minimal.
Women athletes are known to be less strong and powerful than equally trained men [1], muscle strength of women indeed, is typically reported in the range of 40 to 75% of that of men [2]; women are also known to be less powerful than equally trained men.
In the lower limbs, women's strength typically reaches 60–80% of men's strength, while in the upper limbs, it is closer to 60% [36].
Despite the fact that the average man is stronger than the average woman in terms of absolute strength, many women are much stronger than the average man.
What is already known on this topic
Before, during, and after puberty, boys are stronger than girls on average. The sex difference in muscle strength increases markedly with male puberty, averaging ∼10% in 5–10‐year‐olds and then ∼40% in 14–17‐year‐olds.
Studies have shown that men tend to have larger eyes than women, with a larger corneal diameter and a wider angle between the eyes, known as the interpupillary distance. These differences may contribute to a slight advantage in peripheral vision and depth perception for men.
The number of men and women in the world is roughly equal, though men hold a slight lead with 102 men for 100 women (in 2020). More precisely, out of 1,000 people, 504 are men (50.4%) and 496 are women (49.6%).
Recent data from the Centers for Disease Control (CDC) suggests that the average weight of men in the US is 199.8 pounds. The average weight for women is 170.8 pounds.
Historically, power has been distributed unequally. Power and powerful positions have most often been associated with men as opposed to women. As gender equality increases, men still hold more power, including in politics and athletics.
Women tend to score higher than men on measures of emotional intelligence, but gender stereotypes of men and women can affect how they express emotions. The sex difference is small to moderate, somewhat inconsistent, and is often influenced by the person's motivations or social environment.
Abstract. Women generally have a higher percentage of body fat than men. Also, women store more fat in the gluteal-femoral region, whereas men store more fat in the visceral (abdominal) depot.
Females Have More Slow-Twitch Muscle Fibers
Females have a greater proportion of type 1, or “slow-twitch,” muscle fibers compared with males. Slow-twitch muscle fibers are responsible for greater endurance during activities like long-distance running and cycling.
Male skin is, on average, approximately 20% thicker than female skin. It contains more collagen and has a tighter, firmer appearance.
Men's faces are usually longer and broader, with jaw width that often matches the cheekbones. They also have a more projected chin that emphasizes strength. Women tend to have smaller faces with higher brows, narrower jaws, and softer chin projection, all of which contribute to a more feminine aesthetic.
There isn't one single "rarest" eye shape globally, as rarity varies by population, but monolid eyes, hooded eyes, and upturned eyes (cat eyes) are often cited as less common variations compared to the universal almond shape, with conditions like heterochromia (different colored eyes) being rare genetic traits, and specific unusual pupil shapes (like keyhole) also extremely uncommon.
After a barrage of testing, it was shown that women are better at distinguishing among colors. Not to be left out, the same studies show men to excel at tracking fast-moving objects and resolving detail at a distance. It appears one truth remains — men and women still don't see eye to eye.
A newly published study by Brigham Young University researchers found that boys run faster than girls in the 1,600-meter race from ages 6 to 12, with an average performance differential of 7.7%, augmenting the body of evidence indicating that the innate male edge in athletics begins before puberty.
For example, men typically carry 75 percent more muscle mass in their arms than women, which translates to 90 percent greater strength in the upper body. Yep, 90 percent, which can be perhaps best expressed through grip strength.
Besides height, men usually have larger heads and longer arms and legs compared to women, relative to body size. 8 Additional skeletal differences include variations in the skull, long bones like the femur and tibia, as well as the elbows, shoulders, fingers, and thigh bones.
Adult men are typically stronger, more powerful, and faster than women of similar age and training status. Thus, for athletic events and sports relying on endurance, muscle strength, speed, and power, males typically outperform females by 10%-30% depending on the requirements of the event.
Prior research has shown that a significantly lower proportion of women do enough recommended daily physical activity when compared to men, despite the well-known benefits of exercise.
Here's the first spread: Again, women consistently chose the bodies of the guys who looked strong, lean, and athletic in a natural and healthy way. Being on the thinner side was perfectly fine, but being skinny wasn't. This time, though, more women preferred the most muscular guy over the skinny guy.
