The top titans of exercise—resistance exercise and cardiovascular exercise—continue to duke it out for the title of best fitness protocol. When it comes to obese girls, researchers believe they have a champion: cardio.
To determine this outcome, the researchers recruited 44 obese girls, aged 12–18, and assigned them to RE, CE or a nonexercise control group for 3 months. Measures included body weight, waist circumference, oral glucose, insulin sensitivity, body fat, cardiorespiratory fitness, muscular fitness and more.

For the treatment of depression in adults, exercise is as effective as medications or therapy, but not more so, according to a research review published in the Cochrane Database of Systematic Reviews (2013; 9; doi: 10.1002/ 14651858.CD004366.pub6).
Scientists from five universities in the United Kingdom reviewed 39 studies with a total of 2,326 participants in order to update a 2010 review. The earlier review had suggested exercise could reduce depression symptoms, but had found the effect was small and seemed to end if participants stopped exercising.

According to the International Diabetes Federation, current diabetes data and future projections look grim.
The umbrella organization, which comprises more than 200 national diabetes associations in more than 160 countries,
estimates that the number of people living with the disease worldwide will reach 592 million by 2035—or 1 in 10 of the world’s population. The IDF states that there are currently 382 million diabetics worldwide. This information was published in the sixth edition of the IDF Diabetes Atlas.

New research from the University of Navarra in Spain shows that exercise can have a significant positive impact on older seniors.
Scientists recruited 24 adults aged 91–96 and divided them into a nonexercise control group and a “multicomponent” exercise group. The primary focus was to learn how exercise would impact “muscle power output, muscle mass, and muscle tissue attenuation; the risk of falls; and functional outcomes in frail nonagenarians.”
