Abstract
Background: This study evaluates the effect on power produced during a modified lifting task in the overweight and obese after three months of either resistance or aerobic training. Methods: Seventeen male subjects divided randomly into two groups performed deadlift and deadlift high pull, both with increasing weights up to maximal power, prior to and after the training programs (three sessions per week). Results: Their mean power increased significantly during the deadlift at 20 kg (14.3%, p = 0.026), 30 kg (17.7%, p = 0.008), 40 kg (16.5%, p = 0.011), 50 kg (14.5%, p = 0.020), and 60 kg (14.3%, p = 0.021) and during the deadlift high pull at 30 kg (9.9%, p = 0.037), 40 kg (10.1%, p = 0.035), and 50 kg (8.2%, p = 0.044) after the resistance training. However, the group that participated in the aerobic training failed to show any significant changes in power performance during either the deadlift or deadlift high pull. Conclusion: Three months of resistance training enhances power outputs during a lifting task with weights from 30 to 50 kg (~40–60% of 1-repetition maximum) in the overweight and obese. Because this test was sensitive in revealing pre-post training changes in lifting performance, it should be implemented in the functional diagnostics for overweight and obese individuals and also complement existing testing methods.
Highlights
Obesity is often identified as a factor associated with functional task limitations [1,2,3,4]
31.3 ± 4.0 kg·m−2, and body fat from 30.6% ± 4.7% to 29.3% ± 5.1%). Mean power during both the deadlift and the deadlift high pull increased from lower weights up to the maximum
Given the low physical fitness in these subjects, who all had a predominantly sedentary lifestyle at the beginning of the study, it is likely that the acquisition of a certain degree of motor skills contributed toward the enhancement of muscle power during a modified lifting task in a form of the deadlift high pull
Summary
Obesity is often identified as a factor associated with functional task limitations [1,2,3,4]. The obese are often less efficient in manual work-related tasks that demand prolonged physical effort and/or require dynamic transfer of torque and momentum throughout the kinetic chain. This is especially relevant during lifting tasks. Conclusion: Three months of resistance training enhances power outputs during a lifting task with weights from 30 to 50 kg (~40–60% of 1-repetition maximum) in the overweight and obese Because this test was sensitive in revealing pre-post training changes in lifting performance, it should be implemented in the functional diagnostics for overweight and obese individuals and complement existing testing methods
