1.6 Grams of Protein a Day Per Kilogram of Weight
To answer the simplest question of whether taking in more protein during weight training led to larger increases in muscle size and strength, the researchers added all of the results together.
[...]
But those who did ramp up their protein gained an extra 10 percent or so in strength and about 25 percent in muscle mass compared to the control groups.
The researchers also looked for the sweet spot for protein intake, which turned out to be about 1.6 grams of protein per kilogram of body weig...
notes The Problem With Experimentation in the Real World
Government policies—from teaching methods in schools to prison sentencing to taxation —would also benefit from more use of controlled experiments. This is where many people start to get squeamish. To become the subject of an experiment in something as critical or controversial as our children’s education or the incarceration of criminals feels like an affront to our sense of fairness and our strongly held belief in the right to be treated exactly the same as everybody else. After all, i...
1 Timo Hannay observes that we cannot experiment with classrooms and prisons because finding one experiment works means another didn't, creating winners and losers and offending our sense of justice.
Practice Walking Helps Infants Walk Earlier
In fact, contrary to all of the early anecdotes claiming that practice has no effect on the onset of walking, one carefully controlled study has shown that special exercise can indeed accelerate it. In this study, a group of newborns were given just ten minutes per day of "practice walking." Every day between one and nine weeks of age, the baby would be held upright by a parent, with his feet on a table, and allowed to exercise his stepping reflex. Two additional groups of babies received, re... notesBy having the parent hold the infant upright on a table to practice walk for just 10 minutes a day, they are able to accelerate the child's acquisition of this skill; however, infant walkers are found to be detrimental to this purpose for the lack of feedback they provide.
The Importance of Vestibular Stimulation in Infants
One study offers particularly provocative evidence of the benefits of vestibular stimulation. These researchers exposed babies, who ranged in age from three to thirteen months, to sixteen sessions of chair spinning: Four times a week for four weeks, the infants were seated on a researcher's lap and spun around ten times in a swivel chair, each spin followed by an abrupt stop. To maximize stimulation of each of the three semicircular canals, the spinning included one or two rotations in each d...Giving babies four "spin" sessions in a chair improved their reflexes and motor skills. Also, jiggling and rocking babies sorts out their discombobulation and allows them to focus and learn for a period of time.
Chinese Women Stave Off Death to Perform their Ceremonial...
But there's something more: the Harvest Moon Festival is an important holiday in traditional Chinese communities in America. In the week preceding the festival, the death rate in the community is found to fall by 35 per cent. In the following week the death rate jumps by 35 per cent. Control groups of non-Chinese show no such effect. You might think that suicides are responsible, but only deaths from natural causes are counted. You might think that stress or overeating might account for it, b... notesBefore the Harvest Moon festival, deaths drop off, but surge afterwards.
