This study examined the association between work performance and lifestyle habits among Japanese employees. The results revealed that insufficient sleep was the predominant factor affecting work performance in men and women, followed by lack of regular exercise and eating late-evening meals. Furthermore, the study indicated that men were more likely to exhibit lifestyle habits that impacted work performance than women.

Researchers have uncovered startling connections between micronutrient deficiencies and the composition of gut microbiomes in early life that could help explain why resistance to antibiotics has been rising across the globe. The team investigated how deficiencies in crucial micronutrients such as vitamin A, B12, folate, iron, and zinc affected the community of bacteria, viruses, fungi and other microbes that live in the digestive system. They discovered that these deficiencies led to significant shifts in the gut microbiome of mice -- most notably an alarming expansion of bacteria and fungi known to be opportunistic pathogens. Importantly, mice with micronutrient deficiencies also exhibited a higher enrichment of genes that have been linked to antibiotic resistance.

There is a well-known relationship between good physical fitness at a young age and a lower risk of cardiovascular disease later in life. However, when researchers adjusted for familial factors by means of sibling analysis, they found a weaker association, although the link between high body mass index (BMI) and cardiovascular disease remained strong.

Researchers reveal that vitamin B12 significantly boosts the efficiency of cellular reprogramming, thus holding promise for regenerative medicine. Vitamin B12 supplementation shows potential in speeding up tissue repair in a model of ulcerative colitis -- an observation that points to potential new treatments for inflammatory diseases.

A study found people who have a healthy weight use more energy during the day, when most people are active and eat, while those who have obesity spend more energy during the night, when most people sleep. Researchers also found that, during the day, those with obesity have higher levels of the hormone insulin -- a sign that the body is working harder to use glucose, an energy-packed sugar.

Physical fitness since childhood is associated with cerebellar grey matter volume in adolescents. Those who were stronger, faster and more agile, in other words, had better neuromuscular fitness since childhood, had larger Crus I grey matter volume in adolescence.

Men who are overweight or obese at age 18 have a higher risk of 17 different cancers later in life. This has been shown in a study at the University of Gothenburg. The research also describes how the youth obesity epidemic is expected to affect the cancer situation over the next 30 years.

Research in mice shows that the anti-inflammatory properties of exercise may arise from immune cells mobilized to counter exercise-induced inflammation. Immune cells prevent muscle damage by lowering levels of interferon, a key driver of chronic inflammation, inflammatory diseases, and aging.

A positive attitude about physical activity may be related to lower anxiety about aging. Researchers who analyzed results from a multi-state survey say gender, age, marital status and income affect perspectives on exercise and aging but that reframing messages about both can lead to healthy behaviors.

An international study has identified for the first time the optimal number of steps at which most people obtain the greatest benefits, and also shows that the pace at which you walk provides additional benefits.

The risk of serious injury from most exercise is astonishingly small, according to the results of a five-year study. Even forms of sport sometimes considered risky by the public, such as road cycling, are generally safe, suggesting the benefits of taking part in fitness activities far outweigh the dangers.

Researchers have investigated the effect of increased cell temperature on the contractility of skeletal muscle and cardiac muscle by heating the muscle proteins using advanced microscopical techniques. The findings indicated that skeletal muscle is more sensitive to increases in temperature than cardiac muscle, and that heating can rapidly activate the contractile proteins of skeletal muscle, thereby improving muscle performance.

10-20-30 interval training is an effective way to improve running performance and overall health. A new study demonstrates that this kind of training is just as effective for improving your running times and overall fitness, even if your sprints are only at 80 percent. The researchers hope that the new knowledge can encourage more people to adopt this type of training, which benefits both blood pressure and cholesterol levels.
