Good to excellent intra-tester (intraclass correlation coefficient (ICC) range: 0.81-0.97) and excellent inter-tester (ICC range: 0.96-0.99 coefficient of variation range: 2.4-4.1%) reliability was found for all loads. 01) and detecting training-induced changes (R(2): 0.78). Results showed that both assessment methods correlated highly in estimating mean power output at different loads (r range: 0.86-0.94 p <. 10 control group) were assessed before and after completing a seven-week training programme designed to improve maximal power. Subsequently, 20 additional subjects (10 training group vs. For each load, the mean power output was calculated in the W5″ Test as mechanical work per time unit and compared with that obtained from the linear encoder. The number of repetitions, linear displacement of the bar and time needed to complete the test were recorded by two independent testers, and a linear encoder was used as the criterion measure. Thirty trained young men completed as many repetitions as possible in a time of ≈5 s at 25%, 45%, 65% and 85% of one-repetition maximum (1RM) in two test sessions separated by four days. The aims of the present study were to assess the validity and reliability of a novel simple test for estimating the mean power output during the bench press exercise at different loads, and its sensitivity to detect training-induced changes. This simple method could help coaches and athletes achieve their strength training goals, which are partly determined by lifting velocity.

The present results showed that the use of a metronome and a measurement tape may be a valid method to estimate the mean velocity of execution during the bench press exercise.

The SEM for velocity between both testing methods ranged from 0.02 to 0.05 m.s (coefficient of variation, 4.0-6.4% Pearson's correlation, 0.8-0.95). For each rhythm, the mean velocity was calculated with the metronome (time) and the reference distance and compared with that recorded by the linear encoder. A linear encoder was attached to the bar and used as a criterion to measure the vertical displacement over time. They subsequently performed 5 repetitions at 3 different rhythms relative to R (50, 70, and 90% R) for each training load (40 and 60% of 1RM). Subjects were instructed to begin with the barbell at arm lengths and lower it in correspondence with the metronome beep. The range of motion was measured using a regular tape and kept constant during all exercises. To estimate R, the 3 repetitions with highest concentric power, as measured by means of a linear encoder, were selected, and their average duration was calculated and converted to lifting rhythm in beats per minute (bpm) for each subject. After determining their one repetition maximum (1RM) load, we estimated the maximum metronome rhythm (R) that each subject could maintain in the concentric phase for loads of 40 and 60% of 1RM. Fifteen subjects participated in this study. The purpose of this study was to validate a method including a metronome and a measurement tape as inexpensive tools for the estimation of mean lifting velocity during the bench press exercise. Lifting velocity may have a great impact on strength training-induced adaptations.
