Sample Class: Seated Exercises for Older Adults

By IDEA Authors | October 21, 2019 |

Older adults are more susceptible to deficits in cardiovascular fitness, muscle mass, strength and power, which may ultimately lead to losses in physical function. The following chair-based format focuses on improving outcomes for older participants, especially those who may need the support of a chair during exercise. Ready, Set, Sit! offers the variety of three 15-minute training segments (cardiovascular, high intensity and strength/power), while targeting important components that boost overall function.

High-Cadence Cycling and Recreational Cyclists

By Shirley Archer-Eichenberger, JD, MA | October 15, 2019 |

A recent study supports indoor cycling instructors who urge students not to pedal at a cadence above 90 revolutions per minute. Researchers found that at 90 rpm and beyond, pedal forces exerted by recreational cyclists decreased, heart rate increased by 15%, and exercise efficiency and skeletal muscle oxygenation declined.

The study appeared in the International Journal of Sports Medicine (2019; 40 [5], 305–11).

No need for concern about increased death risk from heart disease among experienced middle-aged exercisers who engage in high-intensity activity, at least if they’re male. Findings from a 10-year study of 21,758 generally healthy, very active men—like marathon runners, cyclists and swimmers—showed that even for those with higher coronary-artery calcium levels, athletic pursuits did not elevate risk of death.

Are some of your clients obsessed with achieving their step counts every day? While 10,000 steps is a popular marker, it turns out that taking as few as 4,400 steps per day is associated with a lower risk of death for women with a mean age of 72 years.

“Clearly, even a modest number of steps was related to lower mortality rate among these older women,” said principal investigator I-Min Lee, MBBS ScD, at Brigham and Women’s Hospital in Boston.
