Using two different types of muscles from mice -- the diaphragm and a leg muscle -- sports-medicine researchers from Coventry University in Britain observed that elderly muscles were still stimulated by caffeine, though less so than younger adult muscles. The study’s main author Jason Tallis said that “despite a reduced effect in the elderly, caffeine may still provide performance-enhancing benefits.”
This comes after a U.S. study published in The New England Journal of Medicine indicated that coffee drinkers were less likely to die from various diseases such as stroke or respiratory illness. As The New York Times reported last month, this could be because of various antioxidants found in coffee.
Researchers urge caution in drawing major correlations in these studies between coffee and health. The point of the Coventry University study’s results is the boost, though diminished, caffeine provides to elderly muscles. But as a stimulant, it still carries the risk of higher blood pressure and an increased heart rate.
