KIMURA, N., HAMAOKA, T., KUROSAWA, Y. and KATSUMURA, T., Quantitative Measurements of Aerobic/Anaerobic ATP Production Rate During Submaximal Isometric Exercise. Abv. Exerc. Sports Physiol., Vol.10, No.1 pp.15-24, 2004. The purpose of this study was to establish evaluation methodology for the quantitative measurements of aerobic/anaerobic ATP production rate and to estimate the contribution of oxidative metabolism to anaerobic metabolism (P･Cr breakdown and/ro glyeolysis) during submaximal isometric exercise. Seven male subjegts preformed isometric wrist flexion exercise at 30% of inaximal voluntary contraction (MVC) under restrieted aerobic (Restircted Aero-Ex) and anaeribic (Anaero-Ex) conditons. Restricted Aero-Ex was initiated just after arterial occlusion by a pneumatic cuff. An anaerobic condition in muscles was areated by applying arterial occlusion at rest for approximately 6 min. After O2 deletion, Anaero-Ex was performed under anaerobic condition. From the onset of each exercise, continuous changes in high-energy phosphates and muscle oxygenation (MO2) in the forearm flexor muscle were measured by 31-phosphorus magnetic resonance spectroscopy (31P-MRS) and near infrared spectroscopy (NIRS), respectively. From the changes in phosphorus metabolites and MO2 during submaximal isometric exercise for each condition, the metabolic rates of the initial phase (30s) were calculated. Total ATP production rate was 0.30±0.04 for Restricted Aero-Ex and 0.36±0.05 mM ATP/s for Anaero-Ex. The components of the ATP production rate were the following: 0.16±0.02 (PCr breakdown), 0.08±0.01 (oxidation), and 0.07±0.02 (glycolysis) mM ATP/s for Restricted Aero-Ex and 0.23±０．０３ (PCr berakdown) and 0.13±0.03 (glycolysis) mM ATP/s for Anaero-Ex. The contribution of anaerobic metabolism (PCr breakdown and glycolysis) in Restricted Aero-Ex was significantly power (p<0.05) than that of Anaero-Ex. The ATP production rate components in Restricted Aero-Ex were 52.8% for OCr breakdown, 22.4% for glycolysis and 24.8% for oxidation, and 63.4% for PCr breakdown and 36.6% for glycolysis in Anaero-Ex. These results suggest that under aerobic conditions the contribution of oxidative ATP production lessens the dependence on anaerobic metabolism, in particular PCr berakdown, for the required ATO cost. Furthermore, oxidaive ATP producion is the major source of PCr resynthesis during submaximal isometric exercise. it is possible to non-incasively quantify the ATP production rate during submaximal isometric exercise using a combination of 31P-MRS and NIRS technology.
