Developing and testing of a prototype electro-optical phase encoded position transducer
… for a prototype electro-optical phase encoded position transducer was conducted. The intensity of two IR LED beams were modulated sinusoidally at frequency omega, with a 90 degree temporal phase difference. They further modulated by a pair of sinusoidal optical encoding masks with 90 degree …

The load that maximises the mechanical power output in the power clean: A comparison between different relative strength levels
… 50%-100% of 1 RM of their power clean. A linear position transducer (LPT) was used to measure bar displacement and power output was calculated using both system mass (LPT SM) and bar mass (LPT BM) calculation methods. A mixed factorial design was used to determine whether there was a difference …

The acute effects of transcranial direct current stimulation on the performance of velocity based squat training
… average propulsive velocities using a linear position transducer. In addition, participants reported their perception of exertion using the OMNI-RES scale immediately after each set in order to assess subjective levels of fatigue and exertion. The results indicated that thirteen of the fifteen …

Factors related to creating force-velocity and load-velocity profiles with the squat jump
… compared with a laboratory based four-linear position transducer system (4- LPT) in order to determine if the velocities measured with these devices agreed and were reliable. In Study 4, the mode of exercise (free-weight or Smith Machine) was compared to determine if there was agreement …

Development and application of an eccentric force-velocity profile in rugby union athletes
… rugby union athletes. Force plates and a linear position transducer captured force-time-displacement data across six loading conditions, separated by at least seven days. Eccentric peak force demonstrated good intraclass correlation coefficient (≥ 0.82) and typical error values (≤ 7.3%) for each …

The effect of two different loading schemes and recovery types on kinematic and kinetic parameters in squat exercise
… TI were quantified using a forceplate and linear transducer. Blood lactate samples were taken prior to set one, after setone, after set two and after the last set performed. No significant (P9%) in lactate levels were found between the two loading schemes for any of thekinematic and kinetic …
