“…FLBP and MV achieved during a sit-to-stand were analyzed using the Tendo Weightlifting Analyzer (Trencin, Slovac Republic) as previously described ( 13–15 , 19 ). Briefly, this method has been validated against motion capture analysis to measure functional sit-to-stand power and velocity of the lower extremities ( 13–15 , 19 ). Participant’s weight (kg) was entered into the Tendo software to enable appropriate power calculations.…”

Background and ObjectivesLower-body muscular power and movement velocity (MV) are associated with balance and physical function. The Tendo power analyzer (Tendo) is a portable device that calculates functional lower body power (FLBP) and MV. This reliable (Cronbach’s α = .98) method is validated against motion capture analysis of functional lower body sit-to-stand power and velocity (r = .76). However, the Tendo has not been utilized in discrimination or prediction of falls. We determined the discriminant validity of FLBP and MV among older adults based on the history of falls. These results lay the framework for longitudinal research in FLBP and MV in fall prediction/prevention.Research Design and MethodsCross-sectional investigation examining differences between FLBP and MV during 5 sit-to-stands of 98 community-dwelling older adults (aged 77.5 years, 61% female) classified by the history of fall (no = 59, yes = 39). Participants completed 5 consecutive sit-to-stands (60-second rest between each) with FLBP and MV measured by the Tendo. Multivariate analysis of variance modeling determined between-group differences in functional lower body sit-to-stand average velocity, peak velocity, relative average power, and relative peak power. Binary and forward conditional logistic regression models determined the ability of each measure to discriminate fall history.ResultsFLBP and MV were significantly lower in older adults with a fall history (p < .05). Relative average power and peak power were 15% and 16% lower and average and peak velocity were 18% and 14% slower, respectively among fallers. Logistic regression indicated average velocity was the best discriminator of fall history (p < .05).Discussion and ImplicationsThe Tendo detects differences in FLBP and MV during a sit-to-stand while discriminating fall history. Future longitudinal studies should determine efficacy in fall prediction and applicability toward clinically relevant interventions for fall prevention.

“…As the participant stood the Kevlar string of the Tendo was pulled, measuring linear displacement and time ( 14 ). As previously described ( 19 ), five repetitions were recorded with 60 seconds rest provided between each repetition. Average/peak power (W) and velocity (m/s) for each stand were recorded from the microcomputer ( Figure 3 ).…”

Background In the United States, more than 6 million adults live with Alzheimer disease (AD) that affects 1 out of every 3 older adults. Although there is no cure for AD currently, lifestyle-based interventions aimed at slowing the rate of cognitive decline or delaying the onset of AD have shown promising results. However, most studies primarily focus on older adults (>55 years) and use in-person interventions. Objective The aim of this study is to determine the effects of a 2-year digital lifestyle intervention on AD risk among at-risk middle-aged and older adults (45-75 years) compared with a health education control. Methods The lifestyle intervention consists of a digitally delivered, personalized health coaching program that directly targets the modifiable risk factors for AD. The primary outcome measure is AD risk as determined by the Australian National University-Alzheimer Disease Risk Index; secondary outcome measures are functional fitness, blood biomarkers (inflammation, glucose, cholesterol, and triglycerides), and cognitive function (Repeatable Battery for the Assessment of Neuropsychological Status and Neurotrack Cognitive Battery). Screening commenced in January 2021 and was completed in June 2021. Results Baseline characteristics indicate no difference between the intervention and control groups for AD risk (mean −1.68, SD 7.31; P=.90). Conclusions The intervention in the Digital, Cognitive, Multi-domain Alzheimer Risk Velocity is uniquely designed to reduce the risk of AD through a web-based health coaching experience that addresses the modifiable lifestyle-based risk factors.

“…In general, Masters athletes have more lean body mass, greater peak power, and higher absolute strength than age-matched controls (39). Masters athletes over 60 years old have been shown to have 55% greater aerobic capacity than age-matched older adults, 48% greater time to exhaustion, and delayed physiological deterioration compared to untrained older individuals (17).…”

Exercise leads to robust cardiovascular, musculoskeletal, and psychological benefits that improve quality of life and longevity for older adults, but accompanying improvements in athletic parameters are less well explored. The aim of this review is to summarize some of the most common exercise modalities, namely, Pilates, martial arts (tai chi, Japanese-style karate, hard martial arts), locomotion (brisk walking/jogging and running), Masters sports, resistance training, and high-intensity interval training, in improving athletic performance for older adults. Regular participation in these activities can have robust yet unique impacts on physical performance that prolong exercise participation. In particular, this review will explore benefits in cardiorespiratory fitness, power, strength, flexibility, and balance, thereby hopefully improving endurance, exercise adherence, and overall fall risk. A narrative literature review was performed to explore benefits, pitfalls, and recommendations for some of the most popular exercise modalities for older adults.
