Such tight integration is critical for deriving actionable scientific insight from the MoTrPAC consortium.\u0026rdquo;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EMoTrPAC set the goal at its 11 clinical sites to recruit about 2,600 healthy volunteers across a wide age range (10 to 60-plus years-old) and with balanced participation by gender. Part of the study will test how the response to exercise changes after generally inactive participants complete a 12-week supervised exercise regimen. Sedentary adults will be randomly assigned to an endurance training regimen (treadmill, cycling), a resistance training regimen (weightlifting), or an inactive control group. Low-activity children will be randomly assigned to an endurance training regimen, or to a control group where they pursue their normal activities.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EMeanwhile, a separate group of highly-active adults and youths will contribute to the overall size of the study, helping researchers understand what exercise looks like at the molecular level in those who have exercised vigorously and consistently over an extended period.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EAnother unique facet of MoTrPAC is that volunteers provide samples \u0026ndash; or biospecimens \u0026ndash; before, during, and after exercise that will go through a complex array of molecular assays. MoTrPAC researchers implemented an early study phase with a limited number of adult volunteers that is meant to ensure the complex study design is feasible both for the researchers and the participants before scaling up. The researchers and their data and safety monitoring board are reviewing lessons learned, so that recruitment may continue under optimized protocols. Recruitment currently is on-hold due to safety concerns over COVID-19.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EPreclinical studies in an animal model also set the stage for full-scale MoTrPAC clinical studies, enabling researchers like Gaul (the metabolomics lead of the Systems Mass Spectrometry core facility at the Petit Institute) to generate data from tissues that cannot be collected from humans, expanding the scope of the consortium.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EResearchers at three preclinical animal study sites conducted both a single round of exercise and an exercise training regimen in young and aged rats. Following the exercise round or training, 19 biospecimens were collected per animal, which gives a nearly whole-body look at the effects of exercise, which has never been done before. The biospecimens also provided raw material for the nine chemical analysis sites (such as those at\u0026nbsp;Emory and Georgia Tech) to generate data on exercise responsive biomolecules like genes, indicators of gene activity, proteins, molecules involved in metabolism, and molecular signals in cell-to-cell communication.\u003C\/p\u003E\r\n\r\n\u003Cp\u003ESome data from the preclinical studies is available through the \u003Ca href=\u0022https:\/\/motrpac-data.org\/\u0022\u003EMoTrPAC Data Hub\u003C\/a\u003E, and more is expected soon \u0026ndash; MoTrPAC researchers alone cannot answer every question about the molecular basis of the health benefits of exercise. Making the data widely available brings new perspectives to the topic than would be otherwise possible.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EUltimately, MoTrPAC aims to have a positive impact on human health. The information gathered about endurance and resistance exercise in a wide range of individuals and in different tissues may influence exercise guidelines, making them more tailored for specific groups of people. One day, a doctor may be able to prescribe a personalized exercise routine based on what is likely to create the best outcome for an individual. Other researchers may use the data to identify drugs that mimic the molecular signals of exercise, so-called exercise-mimetics, which could help people who are unable to exercise.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIt\u0026#39;s a massive six-year study that Fern\u0026aacute;ndez calls, \u0026ldquo;a once in a lifetime opportunity.
