Comparison of Periodization Models with Equated Volume and Intensity for Strength

Abstract

The purpose of the present investigation was to determine if significant differences exist among three different periodization programs in eliciting changes in strength.Twenty-eight recreationally trained college-aged volunteers of both genders were tested for bench press, leg press, body fat %, chest circumference, and thigh circumference during initial testing. Following initial testing, subjects were randomly assigned to one of three training groups: 1) Linear Periodization, 2) Daily Undulating Periodization, or 3) Weekly Undulating Periodization. No significant differences were observed between groups for bench press, leg press, body fat %, chest circumference, or thigh circumference at all time points. Groups were then collapsed, and significant increases in bench press and leg press strength were demonstrated at all time points (T1-T3). No significant differences were observed between groups, however, each of the three models proved effective in increasing bench press and leg press strength over the course of nine weeks.
