The Effect of a Dairy-Based Recovery Beverage on Post-Exercise Appetite and Energy Intake in Active Females

Abstract

This study was designed to assess the effect of a dairy-based recovery beverage on post-exercise appetite and energy intake in active females. Thirteen active females completed three trials in a crossover design. Participants completed 60 min of cycling at 65% V̇O2peak, before a 120 min recovery period. On completion of cycling, participants consumed a commercially available dairy-based beverage (DBB), a commercially available carbohydrate beverage (CHO), or a water control (H2O). Non-esterified fatty acids, glucose, and appetite-related peptides alongside measures of subjective appetite were sampled at baseline and at 30 min intervals during recovery. At 120 min, energy intake was assessed in the laboratory by ad libitum assessment, and in the free-living environment by weighed food record for the remainder of the study day. Energy intake at the ad libitum lunch was lower after DBB compared to H2O (4.43 ± 0.20, 5.58 ± 0.41 MJ, respectively; p = 0.046; (95% CI: −2.28, −0.20 MJ)), but was not different to CHO (5.21 ± 0.46 MJ), with no difference between trials thereafter. Insulin and GLP-17-36 were higher following DBB compared to H2O (p = 0.015 and p = 0.001, respectively) but not to CHO (p = 1.00 and p = 0.146, respectively). In addition, glucagon was higher following DBB compared to CHO (p = 0.008) but not to H2O (p = 0.074). The results demonstrate that where DBB consumption may manifest in accelerated recovery, this may be possible without significantly affecting total energy intake and subsequent appetite-related responses relative to a CHO beverage.

Fluid, energy and nutrient recovery via ad libitum intake of different fluids and food

“…In this setting, the prescription of ~500mL of milk or other protein containing beverages does not appear to substantially influence post-exercise energy consumption (5,7,26). However, the results of the current study suggest that when presented with the option to self-regulate beverage …”

“…While the effects of consuming different beverages (e.g. protein containing sports drinks or milk) following exercise on subsequent dietary intake have been investigated (5,7,26), these studies all prescribed the volume of fluid.…”

Relation of Aortic Waveforms with Gut Hormones following Continuous and Interval Exercise among Older Adults with Prediabetes

“…Incretin responses to carbohydrates in a meal are blunted when protein is consumed beforehand [ 60 ]. In either case, OGTT and mixed-meal tolerance tests show similar directional post-prandial gut hormone responses [ 61 , 62 ], with some alterations in magnitude of GLP-1 stimulation [ 63 ] and ghrelin suppression [ 64 ]. Another consideration is that gut hormones were measured at 0, 30, and 60 min of a 75 g OGTT.…”

Fueling the Female Athlete: Auditing Her Representation in Studies of Acute Carbohydrate Intake for Exercise

“…For studies where the menstrual status of participants could be classified, poor knowledge or mixed terminology used to describe menstrual status characteristics was noted. For example, several studies described taking measurements during the “follicular” phase or “premenstruation and postmenstruation” in participants who were OCP users ( 18 , 29 ) rather than indicating if measurements were taken during the active or nonactive pill phase and before or after the withdrawal bleed. Various factors may underpin the incorrect terminology and lack of information pertaining to the menstrual status of female participants in these studies.…”
