Arthritis is a major health concern. According to the Centers for Disease Control and Prevention, 23% of all adults in the U.S., more than 54 million people, have arthritis. As a fitness professional, you can make a difference. Both the CDC and the Arthritis Foundation (arthritis.org) agree that exercise is an important tool in arthritis pain management and prevention.

HIIT or CWT: Does Sequence Matter?

By Shirley Archer, JD, MA | January 16, 2020 |

A new study, conducted under the leadership of IDEA author and presenter Len Kravitz, PhD, compared cardiovascular and metabolic responses to two exercise protocols: (1) six bouts of high-intensity interval training (HIIT) followed by three rounds of circuit weight training (CWT) and (2) CWT rounds interspersed with HIIT bouts. Fourteen trained young men (ages 25.7 ± 4.4) participated in the study, completing each of the two programs 3 days apart.

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, 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).

High-Volume, High-Intensity Exercise Is Safe for Men

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

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 10,000 Steps Necessary?

By Shirley Archer, JD, MA | September 23, 2019 |

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.
