ABSTRACTEight NCAA Division I weight-event track and field athletes (4 M, 4 F) followed a periodized training program during a 6-month competitive season. Subjects were tested preseason (W0) and then at 4-week intervals (W4, W8, W12, W16, W20, W24). Training volume was recorded daily and totaled for each 4-week period. Percent fat (%fat) and lean body mass (LBM) were determined via hydrostatic weighing. Performance measurements included the overhead shot (OS), kneeling shot (KS), vertical jump power (VJP), anaerobic power (AP), and anaerobic capacity (AC). At W8 through W24 blood was collected and analyzed for testosterone ([Test]) and cortisol ([Cort]) concentrations. Both sexes demonstrated similar responses to training with increases in LBM, OS, and KS. No changes were observed for %fat, VJP, AP, or AC. The [Test] and [Cort] were similar throughout the training period, but the [Test]:[Cort] ratio was lowest after the 4-wk interval with the highest intensity. The data indicate that varying training volume and intensity will result in increases in LBM, OS, and KS without large alterations in hormonal concentrations.
