Dataset & Syntax of the TEAMS study

<p dir="ltr">This dataset and accompanying syntax originate from the <b>TEAMS study</b>, a randomized controlled trial designed to investigate the optimum training variables in a resistance exercise training and protein intervention for frail older adults to improve muscle strength, mass and physical functioning; a randomized controlled trial. </p><p dir="ltr"><b>O</b><b>bjective I</b> of the study was to determine the optimal training intensity for improving muscle-related outcomes. <b>O</b><b>bjective</b> <b>II </b>was to examine the additional effects of a protein intervention during resistance training with varying training intensities on muscle outcomes. Both objectives were investigated using the attached dataset, provided in <i>.sav</i> and <i>.csv</i><i> </i>formats. The accompanying SPSS syntax can be executed on the <i>.sav</i> file after updating the file path to match the local data storage location.</p><p dir="ltr">As a first step for both objectives, participants randomized to the 20% training intensity group (randomisation group = 1) were excluded, as these individuals were unable to train to muscle failure within the prescribed 10-minute timeframe per exercise. This is done by a filter. Further details on the progressive resistance training protocol can be found in the study protocol.</p><p dir="ltr">To address <b>o</b><b>bjective I</b>, the syntax includes the procedures for running Linear Mixed Models (LMM). Prior to assessing time effects, the dataset must be converted from a broad to a long data structure. The syntax includes the code required for this data restructuring, followed by the LMM syntax to analyze time effects.</p><p dir="ltr">The code for <b>o</b><b>bjective II</b> begins at row 354 and can be executed directly on the original broad structure <i>.sav</i> dataset.</p><p dir="ltr">Access to the dataset can be requested from the corresponding author (<a href="" rel="noopener" target="_blank">e.j.m.biersteker@hva.nl</a>) with a valid justification.</p>
