Energy Intake and Appetite Sensations Responses to Aquatic Cycling in Healthy Women: The WatHealth Study

Abstract

Background: The aim of this study was to investigate energy expenditure, food intake and appetite feelings in response to water- vs. land-based cycling exercises in healthy young women. Methods: Anthropometric measurements and body composition were assessed among 20 women who performed four experimental sessions in a randomized order: (i) a rest condition (CONT); (ii) a 30-min aqua-cycling exercise session (WAT), (iii) a 30-min land-cycling exercise session at the same rpm (LAND), (iv) a land-cycling session at the same heart rate and isoenergetic to WAT (LAND-Iso). Energy expenditure and substrate oxidation were measured by indirect calorimetry; ad libitum energy intake during subsequent lunch was assessed with appetite feelings recorded at regular intervals. Results: Energy expenditure was higher during the 30-min WAT than during CONT and LAND (p < 0.001). Carbohydrate oxidation was higher in the WAT session compared to CONT and LAND (p < 0.05). LAND-Iso duration was significantly increased (+14 min) to reach the same energy expenditure as in the WAT condition (p < 0.05). There was no differences in food intake between sessions. Conclusion: While further studies are needed to optimize the chronic energetic effects of aqua-cycling, the present study suggests that this exercise modality could represent an efficient strategy to induce acute energy deficit.

“…수중 운동 방법 중, 수중에서 자전거를 활용한 아쿠아바이크 운동 은 무릎 관절의 가동성 확보와 통증 및 부종 해소에 효과적이며 [10], 하 지 근력의 향상뿐만 아니라 심폐체력 증진에 매우 효과적인 것으로 나 타났다 [11]. 또한 아쿠아바이크 운동은 지상에서의 자전거 운동보다 에너지 소모가 더 높으며 [12], 수중에서 신체의 정렬을 유지하기 위해 코어(core)근육을 보다 활성화시키는 것으로 보고하였다 [13]…”
