This study aimed to determine the comparative effectiveness of aerobic vs. resistance exercise on cognitive function. In addition, salivary cortisol responses, as an indicator of arousal-related neuroendocrine responses, were assessed as a potential mechanism underlying the effects of these 2 modes of acute exercise on cognition. Forty-two young adults were recruited and performed the Stroop task after 1 session of aerobic exercise, resistance exercise, and a sedentary condition performed on separate days. Saliva samples were collected at baseline and immediately and 30 min after treatment conditions. Acute exercise, regardless of exercise modality, improved multiple aspects of cognitive function as reflected by the Stroop task. Cortisol responses were higher after both modes of acute exercise compared with the sedentary condition and were higher at baseline and 30 min afterward compared with immediately after treatment conditions. These findings suggest that acute exercise of moderate intensity facilitates cognitive function, and, although salivary cortisol is influenced by acute exercise, levels were not related to improvements in cognition.

Objectives: To evaluate the effect of functional movement screen (FMS)-based functional exercise in patients after anterior cruciate ligament reconstruction (ACLR). Design: Randomized, controlled, single-blind trial. Setting: Institutional, single center. Patients: A total of 38 patients who underwent ACLR were recruited and randomly assigned to group 1 (n = 19) or group 2 (n = 19). Interventions: Both groups received 6-month routine rehabilitation immediately after surgery. From the postoperative fourth to sixth month, group 1 received FMS-based functional exercise plus routine rehabilitation and group 2 received routine rehabilitation only. The FMS-based functional exercise was individualized and customized functional corrective exercise, which was designed based on the 3-month postoperative FMS results. The frequency of rehabilitation was 1 hour per session, twice a week, for a total duration of 6 months. Main Outcome Measures: At 3 and 6 months postoperatively, patients were evaluated by FMS scoring, Lysholm Knee Score, and International Knee Documentation Committee 2000 Score. Results: After the intervention, both groups had significantly increased FMS, Lysholm Knee Score, and International Knee Documentation Committee 2000 score. Group 1 had significantly greater changes in FMS (median: 4 vs 3, P < .001), Lysholm Knee Score (median: 24 vs 16, P = .001), and International Knee Documentation Committee 2000 Score (median: 22 vs 8, P < .001) than group 2. Conclusion: The application of FMS-based functional exercise to patients after ACLR resulted in significant improvement in knee function and movements. The authors suggested integrating FMS evaluation and FMS-based training into routine post-ACLR rehabilitation programs.
