ABSTRACT: Although there is considerable research on concurrent training, none has integrated flexible nonlinear periodization and maximal effort cycling in the same design. The purpose of this investigation was to test outcome measures of strength and power using a pretest-posttest randomized-groups design. A strength and endurance group (SE) was compared to a strength, endurance, and maximal effort cycling group (SEC). Both groups used a flexible nonlinear periodization design. Thirteen male and seven female students (mean± SD: age, 22.5± 4.1 years; height, 173.5 ± 12.4cm; weight, 79.4 ± 20.2kg; weightlifting experience, 2.4 ± 2.2 years) participated in this study. Groups were not matched for age, height, weight, weightlifting experience, or sex, but were randomly assigned to a SE (n=10) or SEC (n=10) group. All training was completed within 45 minutes, twice per week (Monday and Wednesday), over 12 consecutive weeks. Both groups were assigned 6.75 total hours of aerobic conditioning, and 13.5 hours of free weight and machine exercises totaling 3,188 repetitions ranging from 5-20 Repetition Maximums (RMs). The SEC group performed 2 cycling intervals per workout ranging from 10-45s. Pre-and posttest measures included chest press and standing broad jump. Analysis of variance showed that there were no significant differences between (SE) and (SEC) on measures of chest press or standing broad jump performance (p=n.s.). Paired sample t-tests (p=.05), showed significant improvement in strength and power in all groups (pretest to posttest), except SE jump performance (p=n.s.). The conclusion from this study is that adding maximal effort cycling does not provide additional strength or power benefits to a concurrent flexible nonlinear training program. However, an exercise professional can take confidence that a concurrent, flexible nonlinear training program can increase strength and power in healthy individuals.
