Historians and anthropologists believed for decades that prehistoric men were responsible for hunting, while women formed groups to collect preys. However, two recent studies found that not only did prehistoric women engage in the practice of hunting, but their female anatomy and biology would have made them better suited for it.

According to the Science Daily website, the two studies, which physiologically evaluated prehistoric women based on fossil remains, found that prehistoric females were quite capable of performing the arduous physical task of hunting prey and were likely able to hunt successfully "over prolonged periods of time."

The researchers found that the female body is better suited for endurance activity, "which would have been critical in early hunting because they would have had to run the animals down into exhaustion before actually going in for the kill."

Two huge contributors are the estrogen and adiponectin hormones, which are typically present in higher quantities in female bodies than in male, and play a critical role in enabling the female body to modulate glucose and fat, a function that is key in athletic performance.

Estrogen, in particular, plays a major role in fat metabolism, helps women going longer and can delay fatigue. Researchers added that with the typically wider hip structure of the female, women are able to rotate their hips, which lengthen their steps.

“The longer the steps they take, the less metabolically costly they are, the greater the distance they can travel, and the faster they can go,” they added.

"When you look at human physiology this way, you can think of women as the marathon runners versus men as the powerlifters," said Cara Ocoboc, co-author of the study from the University of Notre Dame.



Should You Stretch before Exercise? After? Never? Here’s What to Know

Should You Stretch before Exercise? After? Never? Here’s What to Know

For many people of a certain age, high school gym class began with reaching for their toes. Then, over the years, we were told it was better to stretch after exercise.

It turns out, both those things can be true, but the differing advice has created some confusion.

Stretching can help make you more flexible, improve range of motion in your joints — and feel good. David Behm, who researches human kinetics at Memorial University of Newfoundland in St. John’s, Canada, offers this advice on when to stretch and how to do it safely:

Warm up first

It’s almost always good to stretch, but it’s better if you warm up first, said Behm, author of "The Science and Physiology of Flexibility and Stretching." He recommends a light aerobic activity such as jogging, walking or cycling for five or 10 minutes.

Follow that with some static stretching, the traditional way of reaching and holding a position (think back to that gym class). You can then do activity-specific dynamic stretching, in which you warm up the muscles with repetitive movements like leg lifts.

Behm says one minute is "the magic number" for how long to do static stretching per muscle group without fatigue.

Expand your definition of 'stretching'

Should you always stretch before exercising? If it's traditional stretching, not necessarily.

The better question, Behm says, is, "Should people increase their range of motion? Should people have better flexibility? And that is yes, because it helps prevent injuries. It helps with health. But you don’t have to stretch to achieve that."

Resistance training, for instance, can be an effective form of stretching, he said. Doing a chest press increases range of motion in your deltoids and pecs, whether with barbells, dumbbells or machines, so there is no need to stretch beforehand. Just make sure to start with a small amount of weight to warm up and then add more to train.

"You probably don’t have to do extra stretching unless you’re a gymnast, a figure skater, or even a golfer who needs a great range of motion through that swing," Behm said.

Nor do you need to stretch first if you’re going for a leisurely run. Simply start with a slow jog to warm up and then increase the pace.

Don't do it if it hurts

After exercise, "light stretching is OK, as long as you don't reach a point where you're feeling pain," Behm said. Since your muscles will be warm by that point, overdoing it makes you more likely to injure yourself.

Foam rollers can help with muscle recovery and have been shown to increase range of motion as well as stretching.

Do some static stretching before sports

If you’re playing a sport, Behm said, static stretching beforehand helps reduce muscle and tendon injury.

"If you’re going to do an explosive movement, change of direction, agility, sprint, any of these explosive activities that involve your muscles and tendons," he said, "you’re going to be stronger if you do static stretching."

People can especially get in trouble when they go back to a sport they used to play, whether it's tennis, surfing or any sort of team activity.

Also, stretch both sides equally. Lacking flexibility on one side also can lead to injury.

Sounds simple. Why all the confusion? Different studies over the years have either encouraged or discouraged stretching before exercise. Behm says that partly because some studies didn't reflect real-life conditions, or were designed with elite athletes in mind, not regular people.

"If you’re Usain Bolt, it makes a difference," said Behm. Not so much for the rest of us.
