Comparing the medium-term effects of exercise or dietary restriction on appetite regulation and compensatory responses

摘要: Previous studies have shown that exercise (Ex) interventions create a stronger coupling between energy intake (EI) and expenditure (EE) leading to increased homeostasis of the energy-balance (EB) regulatory system compared diet intervention where an un-coupling EI EE occurs. The benefits weight loss from Ex greatly depend on compensatory responses. present study investigated 8-week medium-term program (Ex comprised 500kcal five days per week over four weeks at 65-75% maximal heart rate, whereas decrease in weeks) its effects responses appetite regulation among healthy individuals using between- within-subjects design. Effects acute dietary manipulation behaviours whether and/or pre-disposes disturbances EB were tested.

At Weeks -4, 4, visual analogue scales (VAS) used assess hunger satiety liking wanting (LW increases decreases balance sensitivity.
