Background/Objectives: Hamilton and colleagues invented the soleus push-up exercise and showed that this exercise method was successful in reducing postprandial blood glucose levels in sedentary individuals. The objective of the current pilot study was to assess the efficacy of the soleus push-up in individuals with prediabetes and to evaluate the feasibility of incorporating this exercise method into their daily routine. Methods: Ten participants (mean age: 53.3 ± 2.7 years; four females, six males) with prediabetes were included in the study. Initially, participants underwent an oral glucose tolerance test (OGTT) while being sedentary to establish baseline postprandial blood glucose measurements. During a subsequent OGTT, participants concurrently performed the soleus push-up (SPU) exercise either with or without electromyographic (EMG) feedback. Blood glucose levels were measured at 15 min intervals over the two-hour duration of both OGTTs. Results: We observed that performing the SPU in a sitting position during the oral glucose tolerance test resulted in approximately a 32% reduction in postprandial glucose excursion compared to the sedentary baseline results. This effect was also present in the absence of EMG feedback. Conclusions: Our findings suggest that this repetitive, prolonged contractile muscle activity can improve metabolic regulation in prediabetic individuals without the need for a laboratory setting. SPU may be a viable and effective exercise to support metabolic health in home or work environments. However, further validation is needed with a larger sample size.
SUMMARY: The objective of this study was to assess the efficacy of a previously invented soleus-dominant exercise in reducing postprandial blood glucose levels in individuals with prediabetes and to evaluate the feasibility of incorporating this soleus push up exercise into their daily routine. It seems that performing the mostly soleus-involved activity in a sitting position during the oral glucose tolerance test results in ∼32% lower postprandial glucose excursion than the control results. This effect is also present in the absence of electromyographic feedback. Hereby we conclude that performing this repetitive prolonged contractile muscle activity may help metabolic regulation even in prediabetic people without the need of a laboratory setting. Therefore soleus push up is a potent exercise method that can be effectively completed in a home setting or work environment. However, further validation of this treatment method should be studied in a larger sample size.
