In addition, subjects were required to perform as many repetitions as possible with 75% of their 1-RM in both the squat and bench press exercises. The two power tests were performed prior PLX4032 to the repetitions to exhaustion test. However, the order of the power tests and sets to exhaustion was randomly determined. Subjects returned to the HPL 24 hours later
to perform two 30-sec Wingate anaerobic power tests. Each test was separated by a 5-min active rest. Following the Wingate anaerobic power test on T1 subjects began the 15 day supplement period. Subjects returned to the HPL on days 7 and 8 (T2) and days 14 and 15 (T3) to repeat the same performance tests. All tests were performed at the same time of day. Subjects also completed a Profile of Mood States and a Visual Analog Scale (VAS) for muscle soreness prior to the Wingate anaerobic power testing during each testing session. Figure 1 depicts the testing protocol. Figure 1 Schematic Diagram: Testing Protocol. Maximal Strength Testing The 1-RM tests were performed using methods previously described by Hoffman . Each subject performed a warm-up set PKA activator using a resistance that was approximately 40–60% of his perceived maximum, and then performed 3–4 subsequent trials to determine the 1-RM. A 3 – 5 minute rest period was provided between each trial. No bouncing was permitted for the bench press exercise, as this would have artificially boosted
strength results. Bench press testing was performed in the standard supine position: the subject lowered an Olympic weightlifting bar to mid-chest level and then pressed the weight until his elbows were fully extended. The squat exercise required the subject to place an Olympic bar across the trapezius muscle at a self-selected location. Each subject Acadesine cost descended to the parallel position which was attained when the greater trochanter of the femur reached the same level as the knee. The subject then ascended until Alanine-glyoxylate transaminase full
knee extension. Performance Measures: Repetitions to Exhaustion Subjects performed one set to exhaustion on both the bench press and squat exercises. The loading for each exercise was 75% of the subjects previously determined 1-RM. Subjects were permitted to warm-up prior to the set. Subjects were instructed to perform as many repetitions as possible using proper lifting technique. Repetitions not meeting the range of motion criteria (parallel position for the squat exercise, and bar touching chest followed by full extension of the elbows for the bench press exercise) were discarded. The total number of repetitions performed was recorded. Power output during the squat and bench press exercises was measured for each repetition with a Tendo™ Power Output Unit (Tendo Sports Machines, Trencin, Slovak Republic). The Tendo™ unit consists of a transducer attached to the end of the barbell which measured linear displacement and time. Subsequently, bar velocity was calculated and power was determined.
