Each candidate selected was fully informed of the purpose and risks associated with the procedures, and their written informed consent was obtained. Trial protocol The experiment Vorinostat cell line included three conditions, each of which consisted of a battery of physical performance tests: the first was after the “rest condition” (CON) and the other two were carried out following a tennis-tournament-type situation with matches played on 2 consecutive

days during which the participants ingested either sports drinks (SPD) or placebos (PLA) (Figure 1). For each of the three conditions, the physical performance tests were performed at 3:00 PM on Sunday and 3 hours after the end of the last tennis match (for SPD and PLA). Each of the three test sessions was performed 2 hours and

30 minutes after a CRT0066101 datasheet standardized meal. The order for the three conditions was randomized and each was separated by 2 weeks. All trials were performed on the same indoor, hard-surface (Greenset®) courts. The participants became familiar with the experimental procedures and courts during a training session which took place two weeks before their first test condition. The players were instructed to continue their usual dietary habits, refrain from any changes in food selections or exercise during the trial and asked not to consume any food supplements or functional foods during the study. From 48 hours before each session, training was not allowed and subjects were asked to refrain from consuming caffeine (coffee, tea, chocolate, cola), tobacco and alcohol. In order to minimize the influence of previous evaluation tests, Z-DEVD-FMK in vivo the sequence of tests was selected to propose the most fatiguing tests at the end. The orders of testing and recovery times were the same in each condition: isometric handgrip strength, power (jump height), maximal 20-m sprints, repeated-sprint ability, maximal isometric strength and fatigability of knee and elbow extensors.

through the study. Dietary protocol To verify diet stability, the subjects were instructed to record their food intake during the 48 hours prior to each session. For this purpose, an instruction booklet containing daily menu examples was given to each subject who was trained by a dietician Oxymatrine how to keep their intake diary during the inclusion meeting. Food diary records from each session were analyzed using Nutrilog® 2.10 software (Nutrilog®, Marans, Fance); their analysis revealed no significant difference in total caloric and macronutrient levels (data not shown). During each day of experiments, the diet was standardized as follows: fat 25%, protein 15% and carbohydrate 65%, plus 200 mL of mineral water at each meal. The total energy provided by breakfast, lunch and dinner was 3197, 4443 and 4841 kJ, respectively.
