Few studies have directly compared hamstrings EMG amplitude across a range of common rehabilitation exercises (Cook et al. 1992; Graham et al. 1993; Ayotte et al. 2007; Begalle et al. 2012; Orishimo et al. 2015; Youdas et al. 2015; Tsaklis et al. 2015).

They noted that the quadriceps - to - hamstrings ratio of EMG amplitude ranged from 1.2 for females to 3.6 for males.

Overall, the size of the EMG amplitude recorded (in whatever way it is filtered, processed and reported) is a combination of both direct physiological processes that generate and transmit myoelectricity and a range of other indirectly associated factors that also affect the characteristics of the recording (Kamen & Caldwell, 1996).

Even so, McMahon et al. (2013) did find that full range of motion training produced similar increases in EMG amplitude at all joint angles, while partial range of motion training left EMG amplitude unchanged short muscle lengths, and reduced EMG amplitude at longer other muscle lengths.

Similarly, Shields et al. (2005) also reported that although hamstrings EMG amplitude increased with increasing load during 1 - leg squats, the quadriceps displayed much greater EMG amplitude than the hamstrings at all loads, with the quadriceps - to - hamstrings ratio of EMG amplitude ranging from 2.3 — 3.0.

It is interesting that the non-significant EMG amplitude changes after isotonic training follow a U-shaped curve, but only contribute to greater torque increases than the middle range of motion at short muscle lengths (30 degrees).

Some dynamic exercises may display very different peak and average EMG amplitudes, especially if a muscle is very involved at one end of the range of motion (ROM) and not particularly involved at the other end of the ROM.

There is less information regarding the changes in EMG amplitude after partial range of motion training.

However, the relative EMG amplitudes ranged between 20 — 40 % of MVIC, which is considered insufficient for effectively developing strength and muscular size.

Investigating band placement at the knees, ankles and feet, the researchers found that EMG amplitude increased as the placement progressed from knees to ankles to feet, essentially partly because the external moment arm increased and partly because the band was stretched further for the same range of motion.

However, Struminger et al. (2013) explored the gluteus maximus EMG amplitude during a range of different lower body plyometrics exercises (180 degree jump, frontal plane hurdle hop, double leg sagittal plane hurdle hop, single leg sagittal plane hurdle hop, and split squat jump).

Abstract: «Persistent episodes of extreme weather in the Northern Hemisphere summer have been shown to be associated with the presence of high - amplitude quasi-stationary atmospheric Rossby waves within a particular wavelength range (zonal wavenumber 6 — 8).

The equations for Rossby waves (Calculation of the Meridional Wave Number, Physics of the Parameter, and Calculation of the Amplitudes) show that this can occur if a set of necessary conditions are met: u ¯ > 0 in the midlatitude region; the highest value of l within the waveguide is in the range of the meridional wave numbers lm dominantly contributing to the external forcing with a given m, which provides closeness of the k waves to respective m waves not only in terms of the zonal but also the meridional wave numbers, favoring the QRA of the m waves; the total latitudinal width of the waveguide is no less than the characteristic spatial scale of the relevant Airy function (25), which is used as the boundary condition at its southern and northern boundaries; and latitudinal distribution of l is sufficiently smooth in the waveguide, and both TPs lie within a midlatitude region of ∼ 25 ° N — 30 ° N and ∼ 65 ° N − 70 ° N, as the necessary condition for the application of quasilinear Wentzel − Kramers − Brillouin (WKB) method (25) when solving the equations for Rossby waves.
