The findings suggest that job-related strenuous exercise throughout life may not necessarily extend longevity.<\/strong><\/p>\n\n\n\n<p>Frequent exercise is often touted as key to leading a long and healthy life. But few studies have delved into comparisons in longevity between those who partake in vigorous physical activity and those who lead mostly sedentary lifestyles as a result of their occupation throughout their lives.<\/p>\n\n\n\n<p>Now, Naoyuki Hayashi and Kazuhiro Kezuka of Tokyo Tech&#8217;s Institute of Liberal Arts have conducted an unusual study that calls into question the idea that vigorous daily exercise positively correlates with longevity.<\/p>\n\n\n\n<p>They compared the lifespans of four different groups of Japanese traditional arts performers by examining data from a total of 699 professional male artists, both living and dead, whose birth and death records are all publicly available. They hypothesized that&nbsp;<em>Kabuki<\/em>&nbsp;actors would lead longer lives owing to the high-level physical activity involved in their theatrical performances, compared with&nbsp;<em>Sado, Rakugo and Nagauta<\/em>&nbsp;practitioners, who are known to perform tea ceremonies, recount comic stories and play musical instruments while sitting, respectively.<\/p>\n\n\n\n<p>Using a method called Kaplan-Meier analysis[1], they found that contrary to expectations, the lifespan of&nbsp;<em>Kabuki<\/em>&nbsp;actors was shorter than that of the other three types of traditional artists.<\/p>\n\n\n\n<p>The researchers postulate that one reason for the shorter lifespans of&nbsp;<em>Kabuki<\/em>&nbsp;artists could be that excessive endurance training and physical activity overwhelms the beneficial aspects of regular physical exercise. Another reason might be that in the past,&nbsp;<em>Kabuki<\/em>&nbsp;actors have often worn oshiroi (white powder used for make-up) containing lead, which carries a significant health risk. The use of oshiroi was only banned in Japan in 1934.<\/p>\n\n\n\n<p>The researchers point out their study is not without limitations. For example, the data examined male-dominated professions only, and therefore does not give a portrayal of population-wide longevity including females.<\/p>\n\n\n\n<p>Further work would be needed to evaluate the optimal amount of exercise for protecting health. The possibly beneficial effects of &#8220;non-exercise&#8221; activities such as speaking, singing and playing musical instruments would also need further exploration.<\/p>\n\n\n\n<p>Overall, the researchers say their study represents &#8220;a novel way of extracting information from publicly available data&#8221; and &#8220;contributes to the global trend in addressing reproducibility in science.&#8221;<\/p>\n\n\n\n<p>###<\/p>\n\n\n\n<p><strong>Technical terms<\/strong><\/p>\n\n\n\n<p>[1] Kaplan-Meier analysis: A method of investigating the probability of survival over time for a given group of subjects.
