Brief Summary

The disproportionately low physical activity (PA) in Latinas, particularly muscle-strengthening activities, and related chronic diseases (e.g., obesity, diabetes, cancer) signifies an urgent public health concern. To address the lack of interventions promoting muscle-strengthening activities exclusively for Latinas, the investigators are testing the preliminary efficacy of a culturally and linguistically relevant, web-based aerobic plus muscle-strengthening PA intervention in this at-risk population. The web-based intervention provides a more comprehensive and highly disseminable approach for reducing PA-related health disparities in Latinas.

Outcome Measures

Primary Outcomes (2)

• Change in physical activity as reported by the 7-Day Physical Activity Recall (PAR) from baseline to week 12.

  The 7-Day PAR is an interviewer administered instrument that uses multiple strategies for increasing accuracy of participant recall regarding many types of activities such as time spent sleeping and moderate, hard, and very hard intensity activities.

  Baseline and week 12

• Change in muscle strengthening activities as reported by the Modifiable Physical Activity Questionnaire (MAQ)

  The MAQ will assess frequency, intensity and duration of muscle strengthening activity

  Baseline and week 12

Secondary Outcomes (3)

• Change in objectively measured physical activity as reported by ActiGraph accelerometer wear.

  Baseline and week 12

• Change in upper body strength will be assessed by the one-minute repeated push-up test from baseline to week 12.

  Baseline and week 12

• Change in lower body strength will be assessed by the one-minute repeated squat test from baseline to week 12..
