ABSTRACT
Due to high interaction rates, smart devices are being utilized for mobile health (mHealth) interventions. Multimedia capabilities may be leveraged to improve mHealth exercise interventions. Our purpose was to explore individuals' perceptions of multimedia exercise prompts tailored to their immediate mental/physical states. Using electronic surveys, respondents provided in-the-moment ratings of emotional state, energy, fatigue, physical discomfort, and thirst, with higher scores reflecting a higher "readiness to exercise" (i.e., if a person is currently in a pleasant mood with high energy and low discomfort, he/she is likely to have a greater capacity for a larger dose of exercise). They were then provided with an exercise prompt designed to match their readiness to exercise, demonstrated via text and graphic interchange format (GIF) showing a research member completing the recommended activity. Survey data regarding GIF quality, self-efficacy, and methodological feedback were then collected and analyzed using a combination of parametric statistics and thematic analysis of open-ended feedback. Respondents (N=204; 47±10 years; BMI 29±6 kg/m2) indicated GIFs loaded quickly (5.29±1.2, scale 0-6), were clear (5.36±1.1), and easily understandable (5.43±1.1). High task self-efficacy scores (9.34±1.62, scale 0-10) and statistically significant differences in coping self-efficacy (i.e., how well a person would be able to complete the recommended activity when feeling mentally/physically worse or better; F=3.229, p<.01) were found. Five themes relating to the exercise prompt were noted: improve attractiveness, limiting factors, exercise clarification, liked/understandable/doable, and disliked/unwilling to complete. Further refinement of these methods is warranted prior to using multimedia prompts to elicit actual exercise performance.
ABSTRACT
Flexible nonlinear periodization (FNLP) was designed to optimize sport-specific resistance training by matching bout demand to pre-exercise mental and physical states ("readiness to train"). Before applying this participant-responsive framework to aerobic prescriptions for inactive adults, operational definitions of readiness are needed. Purpose: To identify themes underlying readiness to perform aerobic bouts considered to be low-demand bouts (LDB) and high-demand bouts (HDB) in adults with obesity. Method: Using Qualtrics, 1,059 respondents initiated the online survey. Quality responses from adults with obesity (N = 112) were analyzed. Respondents described physical and mental states necessary to complete an LDB (10-min slow stroll) and an HDB (60-min jog). Data were assessed using content and thematic analyses. Results: Respondents (57% female) could be classified with class II obesity (35 ± 5 kg/m2) and were 48 ± 12 years old. One theme, body integrity (no pain//illness) emerged for both the LDB and HDB. Regarding affect/arousal, both bouts required the need to feel rested and in a positive mood, but the HDB required higher states of arousal ("pumped up"). Specific to the LDB, a recurring theme suggested that it could be completed under normal or worse (hungry, sick) circumstances. Specific to the HDB were themes relating to physical fitness, proper fueling ("hydrated," "not hungry but not too full"), and enhanced motivation ("determination," "focus," "confidence"). Conclusions: These uncovered themes provide empirical evidence to guide the construction of a readiness checklist that can be further validated and applied in adults with obesity undergoing an FNLP-based aerobic exercise prescription.
