4,500 people were tracked using 24-hour monitors for 7 days. Activity levels were studied to determine the effect on short-term memory, problem-solving, and processing skills. As little as six to nine minutes of moderate-to-vigorous activity when compared to sitting, sleeping, or gentle activities yielded higher cognition scores. Cognitive improvement was modest, but increasing time spent in energetic activity increased the measured benefits.

A 12-month controlled trial randomized 189 individuals to spend 70–90 minutes performing 11 exercises or 20–30 minutes performing 5 exercises for 3 months. Outcomes were measured biweekly for the intervention period and again at 6 and 12 months. The two approaches were similar, except for one outcome. In the Knee Injury and Osteoarthritis Outcome Score for function in sports and recreation, high-dose therapy was superior.

Factors evaluated were diet, exercise, social integration, cognitive activity, smoking history, and alcohol use. Participants were categorized as favorable (4-6 positive factors), average (2–3 positive factors), and unfavorable (0–1 positive factor). The “favorable” group had a a slower decline in cognition even if they were APOE e4 carriers.

In a study of more than 800 rural-living men and women with knee osteoarthritis, an 18-month program of diet and exercise versus attention control yielded an average 14-pound greater weight loss in the test group – but not much difference in pain magnitude.

Monty Python fans may benefit from more than just a healthy laugh. These authors rigorously studied the impact on VO2 and energy expenditure of 3 different walking styles: normal gait, “Putey” walk, and teabag walk. Their findings might change how you think about your daily stroll.

In a study originally published in British Journal of Sports Medicine, a sample of nearly 100,000 adults showed that after making adjustments for other activity, weight training was associated with a 9% decline in CVD mortality. A separate study published in Medicine & Science in Sports & Exercise showed a lower risk of colorectal cancer in adults who lifted weights.
