Presentation Abstract

The purpose of this study is to compare muscle activation between Tonal and traditional free-weight exercises. The Tonal is a digital weight system that can add up to 200 pounds of resistance. The Tonal also features unique exercise modes such as Smart Flex. Smart Flex utilizes Tonal's digital weights system to intelligently match the resistance to the exerciser by continuously adding or subtracting weight depending on when their muscles are at their strongest and weakest during an exercise. For this study, participants will complete 3 separate visits, visit one will include one repetition maximum testing and familiarization and visits 2-3 will include exercising with Tonal and free weights. During visits 2-3, participants will perform three separate exercises targeting the biceps, triceps, and anterior and medial deltoids. They will be hooked up to electromyography (EMG) to monitor muscle activation while performing bicep curls, skull crushers, and standing overhead shoulder presses. All exercises will be performed at 65% of each participant’s maximum and five minutes of rest will be provided between each exercise. The expected outcome of this study is that Tonal will result in greater muscle activation due to its unique feature of Smart Flex, which would have important implications for training.
