We examined the acute effect of cold-water temperature on post-exercise energy intake (EI) for 1 h. In a randomized, crossover design, 11 men (25.6 ± 5 y) exercised for 45 min on a submersed cycle ergometer at 60 ± 2% VO2max in 33°C (neutral) and 20° (cold) water temperatures, and also rested for 45 min (control). Energy expenditure (EE) was determined using indirect calorimetry before, during, and after each condition. Following exercise or rest, subjects had free access to a standard assortment of food items of known caloric value. EE was similar for the cold and neutral water conditions, averaging 505 ± 22 (± standard deviation) and 517 ± 42 kcal, respectively (P = NS). EI after the cold condition averaged 877 ± 457 kcal, 44% and 41% higher (P < 0.05) than for the neutral and resting conditions, respectively. Cold-water temperature thus stimulated post-exercise EI. Water temperature warrants consideration in aquatic programs designed for weight loss.

The purpose of this study was to evaluate perceptions of quality of life after a 4-month progressive resistance training program for individuals with multiple sclerosis (MS). A second purpose was to examine participants’ views about factors that facilitated or impeded exercise behavior. Qualitative interviews were conducted with eight females (Mage = 49.86, SD = 6.94) with relapsing remitting MS. Audio-tape recorded interviews were transcribed verbatim and coded. Walking performance improved (M = 13.08%, SD = 7.11). All participants perceived improvements in muscular strength and endurance while six indicated improvements in walking endurance and performance in tasks of daily living. Social benefits of participation were discussed by seven participants including interactions in the exercise environment. We concluded that supervised resistance training may promote improvements in QOL for women with relapsing remitting MS.
