Cognitive benefits from high-intensity interval training may last for years – Harvard Health

Engaging in regular exercise is linked to multiple health benefits, including maintaining cognitive abilities and perhaps reducing the risk of dementia.

Results from a study published online July 8, 2024, by Aging and Disease suggest high-intensity interval training (HIIT) may be better for brain health than other, less vigorous routines. HIIT workouts consist of repeated cycles of short bursts of high-intensity exercise followed by brief “recovery” periods of lower-intensity movement.

In the study, researchers enrolled 151 healthy adults, ages 65 to 86, in a six-month exercise program. Participants underwent a battery of tests to assess function in the hippocampus — the brain area associated with learning and memory. Everyone was randomly assigned to do one of three half-hour exercise routines: balance and stretching, brisk walking on a treadmill, or four HIIT cycles on a treadmill. (Each HIIT cycle consisted of four minutes at 85% to 95% of a person’s maximum heart rate, followed by three minutes of recovery.)

Everyone did approximately 30-minute workouts three days a week for about six months, for a total of 72 sessions. On repeat testing, only the HIIT exercisers showed positive changes in hippocampus functioning compared to their initial evaluation. At a follow-up evaluation five years later, the researchers found that again only the people in the HIIT group retained their improved cognitive function, even if they were no longer doing HIIT.

“We naturally lose muscle mass, reaction speed and balance as we age,” says this elite Hollywood coach who’s trained everyone from Margot Robbie and Scarlet Johansson to Richard Madden and Pedro Pascal — but recommends doing step-ups to undo the damage of aging in your glutes, quads and calves

“We naturally lose muscle mass, reaction speed and balance as we age,” says this elite Hollywood coach who’s trained everyone from Margot Robbie and Scarlet Johansson to Richard Madden and Pedro Pascal — but recommends doing step-ups to undo the damage of aging in your glutes, quads and calves

There’s a reason why some of the most effective exercises tend to mirror movements in real life. It’s not because personal trainers and coaches lack imagination, but because the body doesn’t care how creative your programming is — it cares whether you can climb a flight of stairs without grabbing the banister, for example, or if you can catch yourself from a stumble.

These are just a few of the benchmarks that matter in later life, and for elite performance coach David Higgins — who has trained everyone from Margot Robbie and Scarlett Johansson to Samuel L. Jackson, David Harbour, Game of Thrones’ Richard Madden and the entire cast of The Batman, among many others — one exercise sits at the top of the list for anyone over 50: the step-up. Here’s why.

HFA Submits Comments to USTR Regarding Trade Policy – Health & Fitness Association

HFA urges targeted trade policies to protect the fitness industry.

This week, HFA submitted comments to the Office of the US Trade Representative (USTR) on two important trade policy dockets that could have significant implications for exercise equipment manufacturers, suppliers, and fitness facility operators. 

Section 301 Tariff Proceeding
USTR sought comment on proposed tariffs from its Section 301 forced labor investigation, including possible product exclusions based on domestic availability and economic impact.

HFA submitted comments that advocated excluding exercise/rehabilitation equipment and critical components, citing irreplaceable global supply chains and the industry’s role in public health, chronic disease prevention, and military readiness.

USTR proposed a new Board to identify non-sensitive products for reciprocal tariff reductions with China.

In comments submitted to USTR, HFA recommended designating exercise equipment as “non-sensitive” and eligible for negotiation, prioritizing products that boost US manufacturing and affordability, and setting criteria recognizing public health, productivity, and military readiness benefits.

The HFA thanks member operators, manufacturers, and suppliers whose data strengthened these submissions. Your efforts are helping HFA advocate for trade policy that supports the fitness industry.
