This study was conducted in an effort to determine if a linear or nonlinear periodized resistance training program had a greater tendency to contribute to a state of overreaching over 8 weeks. Simple outcome measures were used in an effort to determine the onset of overreaching. These measures included average sleeping heart rate, standing broad jump, 10- yard dash, seated medicine ball throw, ratings of perceived exertion (RPE), one repetition maximum (1RM) back squat, and 1RM bench press. The participants were 25 (18 female and 7 male) college students in the Kinesiology major at Western Washington University. Subjects were separated into one of three groups: a control, linear periodized (LP), or nonlinear periodized (DUP) training group. After 8 weeks both training groups significantly increased their 1RM back squat and bench press (p<0.05). The DUP group increased their mean 1RM bench press and back squat from 46.30 ±18.47 kg to 50.83 ±19.26 kg and 67.15 ±20.54 kg to 79.34 ± 23.80 kg, respectively. The LP group increased their mean 1RM bench press and back squat from 46.82 ± 25.96 kg to 51.14 ± 25.87 kg and 74.77 ± 33.22 kg to 84.09 ± 30.10 kg, respectively. All groups significantly improved (p<0.05) their standing long jump performance over the course of the study. The control group improved from a mean of 1.86 ± 0.13 m to 2.04 ± 0.17 m, LP from 1.89 ± 0.40 m to 2.03 ± 0.41 m, and DUP from 1.87 ± 0.42 m to 1.99 ± 0.40 m. Only the DUP group significantly improved their seated medicine ball throw performance (p<0.05) from a mean of 4.09 ± 0.78 m to 4.46 ± 0.69 m. The LP and DUP groups significantly decreased (p<0.05) their 10-yard dash times from a mean of 1.85 sec ± 0.15 to 1.75 sec ± 0.18 and 1.84 sec ± 0.14 to 1.77 sec ±0.14, respectively. Average sleeping heart rate and RPE did not change significantly in any group. The lack of a significant decrease in performance measures or increase in average sleeping heart rate or RPE in either training group caused the null hypothesis to be accepted.
