Incorporating intervention fidelity components into randomized controlled trials promoting exercise adherence in heart failure patients.

Intervention fidelity (IF) in behavioral interventions is complicated by their dynamic and interactive nature. Translation of the outcomes to practice may be diminished by lack of fidelity. The purpose of this paper is to describe a systematic, evidence-based IF approach in a complex, multicomponent behavioral change study.

Effects of the HEART Camp Trial on Adherence to Exercise in Patients With Heart Failure.

Background: Few exercise training studies in patients with heart failure (HF) report adherence to guideline-recommended 150 minutes of moderate-intensity exercise per week, and no studies have focused on a primary outcome of adherence.

Methods And Results: This randomized controlled trial evaluated the effect of a multicomponent intervention, Heart Failure Exercise and Resistance Training (HEART) Camp, on adherence to exercise (after 6, 12, and 18 months) compared with an enhanced usual care (EUC) group. Patients (n = 204) were 55.

BASIC Training: A Pilot Study of Balance/Strengthening Exercises in Heart Failure.

Purpose: The aim of this pilot study was to evaluate the effect of a multicomponent balance and resistance training intervention on physical function, balance, and falls in older (≥65 years) community-dwelling heart failure (HF) patients.

Design: Randomized, two-group repeated-measures experimental design.

Methods: The intervention involved once weekly supervised group sessions with home sessions encouraged twice weekly.

Accelerometer-Measured Daily Activity Levels and Related Factors in Patients With Heart Failure.

Background: Few studies report objective accelerometer-measured daily physical activity levels in patients with heart failure (HF).

Objective: We examined baseline accelerometer-measured physical activity from the Heart Failure Exercise and Resistance Training Camp trial, a federally funded (R01-HL112979) 18-month intervention study to promote adherence to exercise in patients with HF. Factors associated with physical activity levels were also explored.

Exercise Oscillatory Ventilation: Interreviewer Agreement and a Novel Determination.

Introduction: Determination of exercise oscillatory ventilation (EOV) is subjective, and the interreviewer agreement has not been reported. The purposes of this study were, among patients with heart failure (HF), as follows: 1) to determine the interreviewer agreement for EOV and 2) to describe a novel, objective, and quantifiable measure of EOV.

Methods: This was a secondary analysis of the HEART Camp: Promoting Adherence to Exercise in Patients with Heart Failure study.

Team-based Care for Cardiac Rehabilitation and Exercise Training in Heart Failure.

The estimated cost of treating patients with HF in the United States is expected to more than double by 2030.65 This forecast of the impact of HF in the United States should serve as a call to action. Despite well-documented benefits, participation in exercise training and CR programs by patients with HF remains low.

Study of adherence to exercise in heart failure: the HEART camp trial protocol.

Background: Adherence to the Heart Failure Society of America (HFSA) 2010 guidelines recommending 30 minutes of supervised moderate intensity exercise five days per week is difficult for patients with heart failure (HF). Innovative programs are needed to assist HF patients to adhere to long-term exercise. The objective of this prospective randomized two-group repeated measures experimental design is to determine the efficacy of a behavioral exercise training intervention on long-term adherence to exercise at 18 months in patients with heart failure.

Intervention components promoting adherence to strength training exercise in breast cancer survivors with bone loss.

Numerous studies have reported that exercise is safe and beneficial for breast cancer survivors; however, long-term adherence to exercise programs is not easy to accomplish. This secondary analysis examined the demographic and clinical characteristics, adherence to exercise, and cognitive-behavioral intervention components data collected on 120 postmenopausal women with a history of breast cancer and bone loss who had been randomized to the exercise group in a 24-month study. Hierarchical regression was used to identify variables that predicted adherence to exercise.

Development of an instrument to measure adherence to strength training in postmenopausal breast cancer survivors.

Purpose/objectives: To develop a theory-based instrument for assessing barriers and motivators to strength- or weight-training exercise (SWTE) in postmenopausal breast cancer survivors with measurable bone loss after treatment.

Design: Exploratory, descriptive, and methodologic.

Setting: Academic oncology clinics in the midwestern United States, homes, and a fitness center.
