Effects of Integrating Wearable Activity Trackers With a Home-Based Multicomponent Exercise Intervention on Fall-Related Parameters and Physical Function in Older Adults: Randomized Controlled Trial

Effects of Integrating Wearable Activity Trackers With a Home-Based Multicomponent Exercise Intervention on Fall-Related Parameters and Physical Function in Older Adults: Randomized Controlled Trial

Numerous studies have demonstrated the effectiveness of exercise interventions in preventing falls and improving physical function in older adults [8,9]. Each type of exercise (ie, resistance, aerobic, and balance training) has specific benefits, and incorporating high-challenge balance training in exercise programs is particularly emphasized for fall prevention [9,10].

Metabolic Flexibility to Predict Lifestyle Interventions Outcomes (MEPHISTO): Protocol for Predictive Validation Study and Randomized Controlled Trial

Metabolic Flexibility to Predict Lifestyle Interventions Outcomes (MEPHISTO): Protocol for Predictive Validation Study and Randomized Controlled Trial

Participants will then be randomized by an independent investigator to either exercise intervention arm A or exercise intervention and control arm B using a computer-generated random number table. After the baseline visit 1 examination, the A-arm will undergo 12 weeks of a progressive aerobic exercise intervention protocol, after which the clinical examination will be repeated.

Multihealth Promotion Programs on Physical Health and Quality of Life in Older Adults: Quasi-Experimental Study

Multihealth Promotion Programs on Physical Health and Quality of Life in Older Adults: Quasi-Experimental Study

However, systematic reviews and meta-analyses reveal that current health promotion studies predominantly focus on single exercise modalities, yielding inconsistent effects on physical function and lacking in-depth exploration of multicomponent exercise interventions, particularly in practical applications and comprehensive outcome assessments [4,5,7].

School-Based Virtual Reality Programming for Obtaining Moderate-Intensity Exercise Among Children With Disabilities: Pre-Post Feasibility Study

School-Based Virtual Reality Programming for Obtaining Moderate-Intensity Exercise Among Children With Disabilities: Pre-Post Feasibility Study

Intensity: moderate intensity exercise as indicated by a rating of perceived exertion of 5 to 7 on the Borg 0‐10 scale. Time: as many minutes of exercise as possible that could be fit within students’ school schedules (eg, either within their physical education period or a study hall or gap period). Type: VR exercise at home or in the school setting, at the choice of the caregiver and participant.

Comparison of Efficiency of Closed Kinetic Chain Exercises Versus Proprioceptive Exercises in Improving Balance and Gait in People With Hemophilia: Protocol for a Randomized Controlled Trial

Comparison of Efficiency of Closed Kinetic Chain Exercises Versus Proprioceptive Exercises in Improving Balance and Gait in People With Hemophilia: Protocol for a Randomized Controlled Trial

Group 1 is the closed kinetic exercise group, group 2 is the proprioceptive exercise group, and group 3 is the control group. Participants in group 1 and group 2 will receive exercise training twice a week for 12 weeks for a total of 24 sessions of 45 minutes each. The control group will not receive any intervention. Exercise training will continue under the supervision of the physiotherapist. Patients will have completed their factor replacement on the day of exercise.

Interventions to Reduce Serum Per- and Poly-Fluoroalkyl Substances Levels, Improve Cardiovascular Risk Profiles, and Improve Epigenetic Age Acceleration in US Firefighters: Protocol for Randomized Controlled Trial

Interventions to Reduce Serum Per- and Poly-Fluoroalkyl Substances Levels, Improve Cardiovascular Risk Profiles, and Improve Epigenetic Age Acceleration in US Firefighters: Protocol for Randomized Controlled Trial

We also included a smaller intervention group of participants with PFOS Participants randomized into the zone 2 physical activity arm complete a Cardiopulmonary Exercise Test (CPET) before starting their intervention. The CPET uses a mouthpiece and external sensors to measure the heart rate and other cardiovascular health indicators of the individual while they engage in mild exercise on a stationary bicycle.

Older Adults’ Perspectives on Participating in a Synchronous Online Exercise Program: Qualitative Study

Older Adults’ Perspectives on Participating in a Synchronous Online Exercise Program: Qualitative Study

Descriptive characteristics for the ACTIVE, control group (CON), and no-interview participants (N=32). a ACTIVE: exercise group. b CON: waitlist control group. Our thematic analysis identified 3 main themes with respect to participants’ perceptions of exercise in general and with the synchronous online exercise program: health, exercise, and aging beliefs; the pandemic interruption and impacts; and synchronous online exercise programs attenuate barriers to exercise (Textbox 1).

Assessment of Pelvic Motion During Single-Leg Weight-Bearing Tasks Using Smartphone Sensors: Validity Study

Assessment of Pelvic Motion During Single-Leg Weight-Bearing Tasks Using Smartphone Sensors: Validity Study

Specifically, we assessed whether smartphone sensors provide valid estimates of pelvic orientation in the frontal, sagittal, and transverse planes; pelvic mediolateral acceleration; and exercise duration. We further investigated whether smartphone sensors can objectively characterize pelvic motion differences between different single-leg weight-bearing tasks.

Personalized mHealth Intervention (StepAdd) for Increasing Physical Activity in Japanese Patients With Type 2 Diabetes: Secondary Analysis of Social Cognitive Theory Measurements of a Single-Arm Pilot Study

Personalized mHealth Intervention (StepAdd) for Increasing Physical Activity in Japanese Patients With Type 2 Diabetes: Secondary Analysis of Social Cognitive Theory Measurements of a Single-Arm Pilot Study

The ρ of 0.355 between change in SR and change in steps supports the centrality of SR in the changes to exercise behavior [3]. Correlations of social cognitive theory constructs at week 12 of the Step Add intervention for Japanese patients with type 2 diabetes. a SI: strategy implementation. b GC: goal completion. c SE-B: self-efficacy for barriers. d SE-T: self-efficacy for task-specific behavior. e SR: self-regulation. f Not applicable.
