On average, pre-exercise PRO ingestion increased post-exercise REE (p = 0.0076) and decreased post-exercise RER (p < 0.0001) compared to pre-exercise CHO ingestion.
After the second bout maximal isometric torque decreased 21 ± 13%, and 48 h later recovered to pre-exercise level (P < 0.05).
For all dogs of either group the anticipation of activity was associated with an increase in rectal temperature and heart rate from resting to pre-exercise.
Post-exercise HR and BP were measured before participants left the test environment to ensure that these returned to pre-exercise levels.
Albumin decreased to values similar to pre-exercise values by 4-hours following the exercise test, however, RBC, HCT and hemoglobin were decreased at 4-hours compared to pre-exercise values.
IL-6 was elevated following the initial (acute) 90 min isothermal heat strain exercise-heat exposure (day 2) with permissive dehydration ((pre exercise: 1.0 pg mL−1 [0.9], post-exercise: 1.8 pg mL−1 [1.0], P = .032) and when euhydrated (pre-exercise: 1.0 pg mL−1 [1.4], post-exercise: 1.6 pg mL−1 [2.1], P = .048).048
Changes post vs. pre exercise and endurance training, respectively, were subsequently assessed with a post hoc test of Fisher.
Participants completed a consent form and the Pre Exercise Screening Questionnaire, and were then fitted with two HR monitors.
Within the exercised arm, cross-correlation values decreased (pre-exercise r = 0.62 0.64; post-exercise r = 0.37 0.43) while coupling increased within the non-exercised arm (pre-exercise r = 0.51 0.55; post-exercise r = 0.62 0.67).
Pre-exercise screening procedures such as the Sports Medicine Australia Pre-Exercise Screening System (SMaimESS) aim to minimise risks while maximising benefits from physical activity.
Pre-exercise screening will be conducted using Stage 1 of the Sports Medicine Australia Pre-Exercise Screening System [ 23].
