The peak of physical fitness has already passed: strength begins to decline after 26 years for many
The peak of physical fitness has already passed: strength begins to decline after 26 years for many
After analyzing data from long-term observation of hundreds of volunteers, experts came to the conclusion that the peak of endurance and strength occurs between 26 and 36 years.
The results, published in the Journal of Cachexia, Sarcopenia and Muscle, showed that maximum aerobic and muscular endurance is achieved in youth.
By age 63, the overall decline in fitness compared to the best years ranges from 30% to 48%.
People who were physically active in their youth or began to exercise regularly as adults showed higher rates at all follow-up periods.
A team of researchers from the University of New South Wales in Australia conducted observations to understand what happens in the body when a person yawns.
During the experiment, scientists conducted MRI scans of the head and neck of 22 healthy volunteers who were asked to perform various breathing exercises.
Each participant showed its own repeating pattern, which indicates an individual neural rhythm.
Scientists have discovered that when a person yawns, a special fluid (cerebrospinal fluid) comes out of the brain.
Researchers have established quantitative relationships between the agrophysical properties of soil and tractor operating modes.
Field tests were carried out on three agricultural backgrounds of the Middle Volga region: compacted plowing, freshly plowed field and stubble.
According to scientists, the introduction of automated systems with sensors for determining soil type will allow tractors to automatically select the most economical and productive operating mode.
The resulting formulas can also be used in preparing recommendations for the operation of tractors and choosing modes for plowing, harrowing, cultivating and sowing.
Scientists analyzed the remains of 82 people from Alsace (circa 4300–4150 BC) and found differences between conventional burials and pits containing bodies and trophies.
One of the most striking patterns concerned sulfur isotopes.
The analysis showed that the burials represented a complex, purposeful ritual, rather than random corpses of victims of inter-tribal strife.
A new isotope study of Neolithic mass deposits in northeastern France suggests that some of Europe's earliest wars did not end with a cessation of fighting.
