Blood lactate concentrations increase significantly during intense exercise as anaerobic glycolysis becomes the dominant energy pathway [15]. In addition, the combined ingestion of protein and leucine with carbohydrate selleck chemicals has been shown to increase post exercise muscle protein in male subjects [16]. BCAAs also activate key enzymes in protein synthesis [17], and act in a synergistic fashion with insulin to allow skeletal muscle to coordinate protein synthesis [18]. In addition, SOmaxP contains isomaltulose (palatinose) as part of its

carbohydrate moiety. This carbohydrate is present in honey and has been associated with delayed digestion and absorption, which may account for the difference in body fat changes between the SOmaxP group and the CP group. Oizumi and colleagues (2007) developed a palatinose-based balanced formula (PBF) for use in human subjects with impaired glucose tolerance [19]. During a 12-week cross-over study of dietary intervention in 23 subjects with impaired glucose tolerance, the authors found Ipatasertib mw that A 250 kcal can of PBF once per day had beneficial effects on serum free fatty acid levels and visceral fat area. Visceral fat area decreased by 17.1% in the PBF period compared to 5.1%

in the control period. Abdominal fat area decreased by 7.7% in the PBF interval while gaining 3.7% in the control period. Free fatty acids decreased by 22% in the PBF intervention, while increasing by 18.7% during the control period, and the 2-hour post-prandial glucose level decreased by 15.7% in the PBF intervention group while increasing

by 0.8% in the control period. A possible mechanism for this finding was described in an animal study by Matsuo et al. (2007), who found that a palatinose-based liquid formula suppressed postprandial glucose level and reduced visceral fat accumulation compared to a standard formula [20]. These Phosphoglycerate kinase data suggest that palatinose-based carbohydrates may have beneficial effects on fatty acid and glucose metabolism. In addition, Achten et al. (2007) compared the oxidation rates from orally ingested sucrose and palatinose (250 kcal) during moderately intense exercise [21]. The authors found that in trained athletes cycling for 150 minutes at approximately 60% of VO2 max experienced significantly lower oxygen consumption with palatinose compared to sucrose, resulting in a lower plasma insulin response at 30 minutes compared to sucrose. Subjects consumed either water or 1 of 2 carbohydrate solutions (sucrose or isomaltulose) providing 1.1 g/min of carbohydrate. The authors concluded that the lower carbohydrate delivery and a small difference in plasma insulin may have resulted in a higher endogenous carbohydrate use and higher fat oxidation during the isomaltulose trial than during the sucrose trial.
