Concurrent validation of the OMNI-Resistance Exercise Scale of perceived exertion with elastic bands in the elderly.
Purpose:\ud To examine the concurrent validity of the OMNI-Resistance Exercise Scale of perceived exertion using elastic bands in elder population.\ud \ud Methods:\ud Twenty-six participants performed three separate sets of 15 repetitions (low- medium- and high-intensity) for 4 different exercises (2 for the upper-limb and 2 for the lower limb), over two different testing sessions. The criterion variables were heart rate and applied force (average and maximum). In addition to these dependent variables, the active muscle and overall body OMNI-RES for elastic bands scores were collected at the end of each repetition.\ud \ud Results:\ud Significant differences in heart rate, applied force and …
A lower-limb training program to improve balance in healthy elderly women using the T-Bow® Device
Ageing impairs balance, which increases the risk of falls. Fall-related injuries are a serious health problem associated with dependency and disability in the elderly and results in high costs to public health systems. This study aims to determine the effects of a training program to develop balance using a new device called the T-Bow (R). A total of 28 women > 65 years were randomly assigned to an experimental group (EG) (n = 18; 69.50 [0.99] years), or a control group (CG) (n = 10; 70.70 [2.18] years). A program for lower limbs was applied for 8 weeks using 5 exercises on the T-Bow (R): squat, lateral and frontal swings, lunges, and plantarflexions. The intensity of the exercises was cont…
Time trials versus time to exhaustion tests: Effects on critical 1 power, W′ and oxygen uptake kinetics
Purpose: To investigate single-day time-to-exhaustion (TTE) and time trial (TT) based laboratory tests values of critical power (CP), Wprime (W') and respective oxygen kinetics responses. Methods: Twelve cyclists performed a maximal ramp test followed by three TTE and three TT efforts interspersed by a 60-min recovery between efforts. Oxygen uptake was measured during all trials. The mean response time (MRT) was calculated as a description of the overall V ̇O2 kinetic response from the onset to 2 min of exercise. Results: TTE determined CP was 279 ± 52W and TT determined CP was 276 ± 50W (P = 0.237). Values of W were 14.3 ± 3.4 kJ (TTE W') and 16.5± 4.2 kJ (TT W') (P = 0.028). Whilst a high…
