The final column is included to demonstrate that all participants

The final column is included to demonstrate that all participants completed the test when consuming carbohydrate beverages. P, Placebo; MD, maltodextrin beverage; MD + F, maltodextrin-fructose beverage. Data are presented as mean ± SE; comparisons made for finishers of all trials (first three columns: n = 6) and between test beverages for all finishers (end column: n = 14) * denotes significant difference between relative beverages (P < 0.05). Other physiological and subjective measures during both trials Heart rate, perceived exertion,

blood glucose and gastrointestinal distress assessment Data for mean heart rate (b.min-1), blood glucose and subjective perceived find more exertion are shown in Table 3. During the oxidation trial, mean heart rate was marginally lower with P (F = 4.059; P = 0.029), but only statistically different to MD + F (P = 0.045). However, as no differences were observed for RPETOT, absolute VO2 or power output (P > 0.05)

compliance to the exercise intensity was deemed appropriate. Blood glucose was A-769662 nmr significantly greater with both test beverages in comparison to P during the oxidation trial (F = 26.505; P = 0.0001), selleck kinase inhibitor although no differences existed between MD and MD + F (4.77 ± 0.12 mmol.L-1 and 4.97 ± 0.12 mmol.L-1 respectively, P > 0.05). Mean subjective RPELEGS (using a 0–10 Borg Scale) was significantly lower for MD + F compared with MD (P = 0.021) over the course of the oxidation trial. During the performance trial, greater participant effort was demonstrated via increases in mean heart rate, RPETOTAL and RPELEGS in comparison to the oxidation trial. However, as 8 athletes could not complete the performance trial for P, comparisons were made for finishers of all trials only. Mean heart rate was significantly higher with MD + F (160.7 ± 5.0 b.min-1) compared to both MD and P (151.9 ± 6.3 b.min-1 and 149.0 ± 6.3 b.min-1 respectively, P < 0.03). Mean blood glucose was similar between test beverages during the performance trial (4.18 ± 0.23 mmol.L-1 for MD + F and 4.17 ± 0.22 mmol.L-1 for MD), with both being significantly greater

than P (3.24 ± 0.25 mmol.L-1) Selleckchem Rucaparib only (P < 0.05). No differences were observed between test conditions for RPETOTAL or RPELEGS during the performance trial (P > 0.05). Overall responses to the gastrointestinal distress questionnaire are shown in Table 4. A higher number of significantly positive responses were noted for MD. Bloating and belching severity were considerably greater with MD (22.2% and 19.0%) compared to MD + F (<4.8%) and P (<1.6%) respectively (P < 0.05). Whilst responses for other symptoms were considered minor ie: <7% of all responses, it was noted that symptoms of nausea, stomach problems, and urge to vomit or defecate were observed in the MD trial.
