In this review, the basics of classic reliability theory are addressed in the context of choosing and interpreting an ICC and how the SEM and its variants can be used to construct confidence intervals for individual scores and to determine the minimal difference needed to be exhibited for one to be confident that a true change in performance of an individual has occurred.
ASEP PROCEDURES RECOMMENDATION I: ACCURATE ASSESSMENT OF MUSCULAR STRENGTH AND POWER
The content of this manuscript is intended to assist the reader in collecting valid and reliable data for quantifying muscular strength and power in isometric, isotonic, field tests, and isokinetic modes of exercise.
Mechanomyographic amplitude and frequency responses during dynamic muscle actions: a comprehensive review
There is convincing evidence that during dynamic muscle actions, the M MG signal provides valid information regarding muscle function, and this argument is supported by consistencies in the MMG literature, such as the close relationship between M MG amplitude and power output and a linear increase in MMG amplitude with concentric torque production.
Relationship of critical velocity to marathon running performance
Preliminary data indicate that the CV test may be an attractive field test for assessing marathon performance capabilities, and correlated more highly with marathon time than either O2peak or Thvent.
Mechanomyographic amplitude and mean power frequency versus torque relationships during isokinetic and isometric muscle actions of the biceps brachii.

The anthropometric equations are recommended for one-time estimates of muscle CSA values in healthy, well-nourished young adult males when more sophisticated procedures are not available.
Comparison of Fourier and wavelet transform procedures for examining the mechanomyographic and electromyographic frequency domain responses during fatiguing isokinetic muscle actions of the biceps…
Mechanomyographic and electromyographic time and frequency domain responses during submaximal to maximal isokinetic muscle actions of the biceps brachii
The results indicated that dynamic muscle actions can be used when applying techniques that require a linear EMG amplitude versus torque relationship, and suggested that simultaneous examination of MMG and EMg amplitude and MPF may be useful for describing the unique motor control strategies that modulate dynamic torque production.
Effect of moderate dehydration on torque, electromyography, and mechanomyography
The lack of dehydration effect suggests that MMG may be more reflective of the intrinsic contractile processes of a muscle fiber or the motor control mechanisms than the tissues and fluids surrounding the muscle fiber.

The results of this investigation indicated that the effects of the eccentric weight training were joint angle specific [significant increases at 45 and 75 degrees (p < 0.05)].
