If you are worried about injury risk with sprinting, you could consider rowing.
> Physiologists, in fact, have calculated that rowing a two-thousand meter race — the Olympic standard — takes the same physiological toll as playing two basketball games back-to-back. And it exacts that toll in about six minutes.
The full title "Scientists Identify 3-Minute Exercise That May Outperform 90-Minute Workout" has the "perhaps, maybe, who knows" found in the full article. Flim flam and flummery.
"...three minutes of sprinting produced a dramatic molecular response in the bloodstream, far exceeding the changes seen after 90 minutes of moderate exercise." Key word MODERATE. What about comparing it to HIIT for example?

Capitalization and abbreviations matter. There was nothing wrong with original headline or the article. OP had to tamper and obfuscate it.
All the sites in between only give a vague abstraction of that.
