The aim of the research was to determine how knee extensor strength asymmetry influences gait and variability because these parameters have been related mobility falls in older adults.Strength extensors measured 24 women (65-80 yr). Subjects were separated into symmetrical (SS, n = 13) asymmetrical (SA, 11) groups using an cutoff 20%. walked at a standard speed 0.8 m·s maximal on instrumented treadmill while kinetic spatiotemporal variables measured. Gait calculated as percentage difference...
Stretching is used in an attempt to improve performance and reduce the risk of muscle injury, with little evidence support its effectiveness.Four weeks static or ballistic stretching can attenuate increased soreness decreased flexibility seen after eccentric exercise.Controlled laboratory study.Twenty-nine male subjects were randomly assigned a stretching, control group. On each 4 consecutive days, they completed maximal range motion stretches using Cybex isokinetic dynamometer passively...
The objective of the present study was to evaluate and compare neuromuscular, morphological functional adaptations older women subjected 3 different types strength training. 58, healthy (67±5 year) were randomized experimental (EG, n=41) control groups (CG, n=17) during first 6 weeks when EG group performed traditional resistance exercise for lower extremity. Afterwards, divided into three specific training groups; a (TG, n=14), power (PG, n=13) that concentric phase contraction at high...
Purpose: Innovative assistive technology can address aging-in-place and caregiving needs of individuals with Alzheimer's disease related dementia (ADRD). The purpose this study was to beta-test a novel socially robot (SAR) cohort ADRD caregivers gather their perspectives on its potential integration in the home context.Methods: SAR involved programmable research linked commercially available Internet things sensors receive respond care recipient's behaviour. Eight observed perform two...
Background: Preferred walking speed (PWS), maximal (MWS), and reserve (WSR)—the difference between MWS PWS—can be easily obtained from the 10-m walk test (10MWT) to assess ability function. However, their test-retest reliability has not been determined in persons with unilateral lower-limb amputation (LLA). Objectives: To determine of PWS, MWS, WSR 10MWT LLA. Study design: Test-retest a 48- 120-h interval days. Methods: relative absolute was assessed by intraclass correlation coefficient...
Purpose: The purpose of this study was to determine whether muscle power, activation time, and neuromuscular stimulation are related physical activity patterns in older women. Methods: Forty women (65-84 yr) were assigned high-active (HA) low-active (LA) groups on the basis a historical questionnaire, then they performed series maximal, voluntary, isometric knee extensions visually cued RT task. Fractionated measures taken using three landmarks data: presentation visual stimulus, beginning...
The purpose of the study was to determine whether muscle force, power, and optimal length were affected by 4 weeks static or ballistic stretching. Twenty-nine males (age, 18-60 years) performed maximal hip extensions measure peak torque (PT), rate development (RTD), work (W), PT angle (PTA). Then, participants completed flexibility training extensors followed repetition testing protocol. After training, increased 5.3 +/- 19.0% in group (SG), 7.8 12.7% (BG), 6.1 17.9% control (CG). RTD 4.8...
The purpose of this study was to develop a modified version 3-min all-out cycling test (3MT) using equipment readily available cyclists and identify exercise intensity domains the average power output over last 30 s 3MT (end-test (EP)).Sixteen competitive (V(O2peak) = 60.3 +/- 8.3 mL.kg.min) completed three laboratory visits their own bicycles power-measuring rear wheel. In visit 1, subjects performed an incremental load volitional termination on electronically braked trainer (100 + 25 W...
The objective of this investigation is to study how excess body weight influences the energy cost walking (Cw) and determine whether overweight obese older adults self-select stride frequency minimize Cw.Using mass index (BMI), men women between ages 65 80 yr were separated into normal (NW, BMI ≤24.9 kg·m(-2), n = 13) overweight-obese groups (OWOB, ≥25.0 13). Subjects walked at 0.83 m·s on an instrumented treadmill that recorded gait parameters completed three 6-min trials; a preferred...
Strength and power asymmetries of >10% may negatively impact physical function.Twenty-four healthy participants, 30-60 years age, were assessed for muscle asymmetry during isokinetic knee extension ground reaction force chair-rise vertical jump tasks. Neuromuscular activation coactivation vastus lateralis (VL) biceps femoris (BF) in each condition. Symmetric (SG) asymmetric (AG) groups identified using a 10% criterion.The AG had greater rate development (P = 0.003, d 1.29), but similar peak...
To test the ability of a combination high-velocity/high-resistance training program to enhance knee extensor muscle strength, power, nervous activation muscle, and time in inactive women compare response between young old women.The study involved 49 women, with (18-33 yr, n = 25) (65-84 24) distributed control groups using blocked randomization. Electrically evoked twitches were measured for extensors; then maximal, voluntary, isometric extensions performed visually cued reaction (RT) task,...
Abstract Quinn, TJ, Dempsey, SL, LaRoche, DP, Mackenzie, AM, and Cook, SB. Step frequency training improves running economy in well-trained female runners. J Strength Cond Res 35(9): 2511–2517, 2021—The purpose was to determine whether a short program (15 minutes for 10 days) increase step 180 steps per min would elicit improvements (RE). Experimental ( n = 11) control subjects reported the laboratory 12 consecutive days completed 2 RE tests at 3.4 3.8 m·s −1 (day 1 12), followed by maximal...
