Objectives:

To examine baseline characteristics and change in gait speed and Short Physical Performance Battery (SPPB) scores in participants medically suspended (MS) from a physical activity intervention (PA).

Design:

Randomized controlled trial.

Setting:

University and community centers.

Participants:

Sedentary older adults (N = 213) randomized to PA in the Lifestyle Interventions and Independence for Elders Pilot (LIFE-P).

Measurements:

MS was defined as missing 3 consecutive PA sessions in adoption and transition phases or 2 wk in maintenance phase because of a health event.

Results:

In all, 122 participants completed PA without MS (NMS subgroup), 48 participants underwent MS and resumed PA (SR subgroup), and 43 participants underwent MS and did not complete PA (SNR subgroup). At baseline, SNR walked slower (p = .03), took more prescribed medications (p = .02), and had lower SPPB scores than NMS and SR (p = .02). Changes from baseline to Month 12 SPPB scores were affected by suspension status, adjusted mean (SE) SPPB change: SNR 0.0957 (0.3184), SR 0.9413 (0.3063), NMS 1.0720 (0.1871); p = .03.

Conclusions:

MS participants unable to return to complete the PA in a trial of mobility-limited sedentary older adults had slower walking speeds, lower SPPB scores, and a higher number of prescribed medications at baseline. Change in SPPB scores at 12 months was related to suspension status.

Falls are recognized as the fifth leading cause of death among older adults ( Rubenstein, 2006 ). Previous publications have identified increasing age, female gender, visual impairment, polypharmacy, medical comorbidities, psychological issues, and environmental factors as commonly occurring risk

Despite the lack of associations related to average sleep

prescriptions were designed to include the major components of an exercise program: aerobic, strength, and flexibility training. However, due to individual preferences, goals, and medical comorbidities, there was variation in each individual program. A target intensity of 11–13 on the Borg 6–20 scale was

The mean Timed Up and Go Test score (9.6 s) was consistent with the normative value for an age-matched population of community-dwelling older adults who may have some medical comorbidities ( Steffen et al., 2002 ). No participant required a walking aid; however, one participant

Furthermore, given the research showing differences in insomnia symptoms for those with psychiatric and medical comorbidities ( Ohayon et al., 2004 ), we also conducted our
