Reduced strength, balance, and functional independence diminish quality of life and increase health care costs. Sixty adults (82.2 ± 4.9 years) were randomized to a control or three 12-week intervention groups: bioDensity (bD); Power Plate (PP) whole-body vibration (WBV); or bD+PP. bD involved one weekly 5-s maximal contraction of four muscle groups. PP involved two 5-min WBV sessions. Primary outcomes were strength, balance, and Functional Independence Measure (FIM). No groups differed initially. Strength significantly increased 22–51% for three muscle groups in bD and bD+PP (P < .001), with no changes in control and PP. Balance significantly improved in PP and bD+PP but not in control or bD. bD, PP, and bD+PP differentially improved FIM self-care and mobility. Strength improvements from weekly 5-min sessions of bD may impart health/clinical benefits. Balance and leg strength improvements suggest WBV beneficially impacts fall risk and incidence. Improved FIM scores are encouraging and justify larger controlled trials on bD and bD+PP efficacy.

Effective academic advising in kinesiology is paramount to student success, contribution of the discipline to global health, and preparation of the workforce’s future leaders. Enrollment growth in kinesiology and its curricular breadth impose challenges that are unique from many other academic majors. The American Kinesiology Association convened a preworkshop titled “Advising in Kinesiology: Challenges and Opportunities” in January 2019 to begin dialogue related to advancing effective advising practices in kinesiology. Twenty-six attendees, all of whom were engaged in advising in different roles, participated in presentations and group discussions. This paper summarizes the preworkshop primary findings and offers some best-practice considerations. While it is clear that effective advising is positioned to advance the quality of kinesiology programs and our graduates, there is a dearth of supporting evidence, and addressing this through research is a needed priority.

Less than half of U.S. adults engage in the recommended amount of physical activity (PA). Internet-delivered PA programs increase short-term PA but long-term adherence is largely equivocal.
To determine whether increased PA following the 16-week internet-delivered Active Living Every Day (ALED-I) program is maintained 8 months later in sedentary and overweight rural adults.
In our previous randomized controlled trial (N = 32; 18 intent-to-treat controls, 14 ALED-I interventions), the ALED-I group increased PA (+1384 steps/day; E.S. = 0.95) and reduced central adiposity. Nine original intervention participants and ten delayed intent-to-treat control participants completed ALED-I and an 8-month follow-up. Pedometer-measured PA, anthropometric variables, and cardiometabolic disease risk factors were assessed at baseline, postintervention, and at 8 months.
Control crossover participants increased PA (+1337 steps/day; P = .04). Eight months following completion of ALED-I (N = 19), PA levels relapsed (–1340 steps/day) and were similar to levels before the intervention (6850 ± 471 steps/day vs. 6755 ± 543 steps/day; P = .89). Total cholesterol and triglycerides improved, –9.9% and –18.2%, respectively, and reductions in central adiposity were maintained (97.1 ± 2.2 cm vs. 97.2 ± 2.2 cm; P = .66).
The ALED-I intervention was efficacious in the short-term but did not produce longer-term adherence to PA. Future theory- based internet-delivered interventions that produce habituation of increased PA are warranted. Study conducted in Laramie, WY from January 2007 through November 2007.
