Self-Selected or Fixed-Duration Rep Speed

August 20, 2019

A small study addressed the question of whether one gets better results from performing resistance training reps at a self-selected pace or at a fixed rep duration (2-second concentric phase, 2-second eccentric phase). Researchers from universities in S?úo Paolo recruited 12 resistance-trained men and evaluated exercise volume, muscle activation and time under tension.

Prolonged Sitting May Undo Exercise Benefits

August 20, 2019

Here’s some less-than-good news for your weekend warrior clients. New findings from a small study suggest that sitting throughout the day may alter the typical metabolic benefits of a bout of exercise. Whether sitting for endless hours daily is hazardous to our health because we’re not exercising or whether the health risks of sitting may be counteracted by exercise are questions to which scientists continue to tease out answers. University of Texas at Austin researchers designed a study to shed some light.

Walking Benefits Older Adults With Arthritis

August 20, 2019

People with osteoarthritis who walk briskly as little as 1 hour per week can significantly increase their odds of remaining functionally independent. Northwestern University researchers in Chicago examined more than 4 years of data from more than 1,500 adults—age 49 or older—who had arthritis but no disability. Their activity levels varied. Activity data analysis showed that people who did 1 hour of moderate-to-vigorous activity per week had a higher probability of remaining free from disability than those who exercised less.

Research shows that exercise benefits breast cancer survivors, but many do not stick with programs. What might appeal enough to increase adherence? A pilot study found that group exercise designed specifically for people surviving breast cancer resulted in more improvements to quality of life than similar exercise programming led by personal trainers. The study is available in Oncology Nursing Forum (2019; doi:10.1188/19.0NF.185-97).
