Effects of Age and Sex on the Results of an Ankle Plantar-Flexor Manual Muscle Test; MH Jan, HM Chai, YF Lin, JCH Lin, LY Tsai, YC Ou, DH Lin; Physical Therapy October 2005, vol 85, no 10; The ability to perform 20 or more one-leg heel-rises is considered a “normal” grade for muscle strength of the ankle plantar flexors, regardless of age and strength. Because muscle strength is closely related to age and sex, the “normal” test criterion was re-evaluated in different groups categorized by age and sex. Biometrics Ltd electrogoniometers and instrumentation was used to measure the angle of ankle plantar flexion.

Age Differences in knee extension power, contractile velocity, and fatigability; J Petrella, JS Kim, C Tuggle, S Hall, M Bamman; Journal of Applied Physiology 2005, 98:211-220; The purposes of this study were to examine age and gender differences in knee extension strength, power, and fatigue using open- and closed-chain testing procedures. Knee position and flexion/extension movement was measured using Biometrics Ltd electrogoniometers and neural activity of the right knee extensors was measured for each of three superficial quadriceps muscles using Biometrics Ltd EMG sensors. EMG were digitized at 1000 Hz and electrogoniometer inputs at 500 Hz, and data from each input were analyzed simultaneously using Biometrics Ltd DataLINK with software version 2.0.
