|Ice cold baths are retarded. A cosy hot tub and a cup of coffee make a way better peak conditioning strategy.|
Even in the absence of additional caffeine ingestion the latter increases the amount of circulating free fatty acids by 52% (80% with caffeine) with the ~200-300mg of caffeine before the bath it almost doubles the amount of free fatty acids and increases the circulating leptin levels by 28% (vs. 5.6% w/out caffeine).
Whether the significantly more pronounced reduction in waist circumference (8.9mm vs 6.7mm) Tae-Wook Kim & Jeong-Beom Lee observed in their 9 male subjects (age ~26y; BF% 20%; no habitual caffeine consumers) is yet a result of real fat loss, remains highly questionable. However, even if that's not the case sitting in a hot tub after having a large cup of coffee would still qualify as a potentially valuable peak-conditioning technique before a contest or photo shoot - or, for the less ambitious, before the high school reunion or the a first date ;-)
