text: Yo, check it, listen up, I got a study to share,
  We're talkin' 'bout sleep apnea patients in this here affair.
  The aim was to see if exercise would make a change,
  Safe or not, and if RDI would rearrange.
  
  Eleven patients, hold up, let me break it down,
  One lady, ten dudes, average age 'bout fifty-two in town.
  They had moderate to severe sleep apnea, that's the deal,
  Already treated with CPAP, tryna see if exercise is real.
  
  For six months straight, they hit the gym, twice a week,
  Two hours each time, workin' up a sleep apnea beat.
  Before and after, tests were done, let me explain,
  Polysomnography, bicycle test, all up in their brain.
  
  Lactate profile, echocardiography, body stats were checked,
  Weight and height, yo, they weren't wrecked.
  No adverse effects, no problems with the heart and lungs,
  Exercise was safe, no worries, no tongues.
  
  No change in body weight, fitness level stayed the same,
  No difference in oxygen levels, no improvement in the game.
  But hold up, there's somethin' we did find,
  The RDI decreased, droppin' from thirty-two point eight to twenty-three point six, that's the kind.
  
  We didn't see a change in sleep architecture, that's true,
  But exercise helped with the RDI, that's what we knew.
  Conclusion? Mild to moderate exercise is safe and sound,
  For sleep apnea patients, it's a path that can be found.
  
  So there you have it, the study's rap rendition,
  Physical exercise can help with sleep apnea's condition.
  No need to worry 'bout the risks, it's all good,
  Get movin', stay healthy, just like you should!
