Twitter-based social support group vs Fitbit only to decrease sedentary behavior in women

/0 Comments/in /by

A Twitter-delivered intervention for promoting physical activity among inactive women from a heart clinic was feasible, acceptable, and demonstrated preliminary efficacy in increasing daily active hours, daily total steps, and the ratio of sitting-to-moving from pre to post for the intervention compared with the control. Lessons learned from this pilot suggest that the next study should expand the recruitment pool, refine the intervention to increase group engagement, and select active hours, total steps, and ratio of sitting-to-movement as primary sedentary behavior measures.

Active Voice: Can Creatine Supplementation Improve Properties of Muscle and Bone Mass in Older Adults? – American College of Sports Medicine

/0 Comments/in /by

After the fourth decade of life, muscle and bone mass decrease by ~ 1%-2% per year. This age-related reduction in muscle and bone (including muscle density and bone geometry, as indicators of muscle and bone quality) increases the risk of falls and fractures. Approximately one-in-three older adults experience a fall each year, with many experiencing multiple falls. Falls may lead to physical inactivity and premature morbidity. Therefore, lifestyle interventions that improve properties of muscle and bone may potentially reduce the risk of falls and fractures in older adults.

Active Voice: Resistance Training May Reduce Cardiovascular Risk – American College of Sports Medicine

/0 Comments/in /by

Resistance training (i.e., weightlifting) is increasing in popularity and is now recognized as an important component of a general exercise program. The current Physical Activity Guidelines for Americans recommend regular muscle-strengthening exercise for healthy men and women, older adults and adults with chronic conditions. The proposed benefits of regular resistance training typically focus on improved neuromuscular function, strength, endurance and bone density. However, a growing body of evidence suggests resistance exercise may also induce adaptations to the cardiovascular system…
