Hi, All -
I love this forum for the great knowledge and insight being passed on. Thank you.
This is my first time posting.
Per Tim's comment, the HIIT activity did include aerobic 2 days of treadmill walking:
"HIIT was 3 days per week of cycling (4 3
4 min at >90% of peak oxygen consumption [VO2 peak] with
3 min pedaling at no load) and 2 days per week of treadmill
walking (45 min at 70% of VO2 peak)."
Also of note, the exclusion criteria for the study included the following:
"Exclusion criteria were
structured regular exercise (>20 min,
twice weekly), cardiovascular disease,
metabolic diseases (type 2 diabetes mellitus,
fasting blood glucose > 110 mg/dL,
and untreated hypothyroidism or hyperthyroidism),
renal disease, high body
mass index (BMI > 32 kg/m2), implanted
metal devices, pregnancy, smoking,
and history of blood clotting disorders.
Exclusionary medication included anticoagulants,
insulin, insulin sensitizers,
corticosteroids, sulfonylureas, barbiturates,
peroxisome proliferator-activated
receptor g agonists, b blockers, opiates,
and tricyclic antidepressants."
