Sentences with phrase «at a long muscle»

In summary, it seems likely that the increases in muscle fascicle length that happen as a result of eccentric training lead to greater increases in high - velocity strength, smaller increases in RFD, and greater increases in strength at long muscle lengths (by a shift in the optimum angle).

Increasing muscle fascicle length through eccentric training could therefore be a valuable method for improving athletic performance in movements that have peak contractions at long muscle lengths, such as the terminal swing phase of sprinting, or the ground contact phase of sharp change of direction (COD) maneuvers.

The increases in muscle fascicle length seem to be affected by the amount of stretch during training, because training at longer muscle lengths leads to greater adaptations (Guex et al. 2016).

Herzog and colleagues (Herzog et al., 1991) compared the rectus femoris moment — length relationship of high - performance athletes engaged in different disciplines, who chronically use this muscle at distinctly different lengths, and found that runners were relatively stronger at longer muscle lengths and cyclists stronger at shorter muscle lengths.

Static stretching performed before activity has been shown to cause performance reductions at shortened muscle length, but moderate performance increases at longer muscle lengths.

This is because anteroposterior exercises usually cause a peak contraction to occur at a short muscle length, while axial exercises most commonly produce their peak contraction at long muscle lengths.

Joint angle - specific strength gains at longer muscle lengths tend to be caused by regional hypertrophy.

Isometric training at long muscle lengths improves strength at that joint range of motion, and also (albeit slightly less) at shorter muscle lengths.

The reason for the difference between the changes in joint angle - specific strength and the changes in joint angle - specific neural drive is that both peripheral and central factors are operating, and the impact of joint angle - specific neural drive is greater after training at short muscle lengths, while the impact of peripheral factors (like regional muscle size and / or muscle fascicle length) are greater after training at long muscle lengths.

Similarly, isometric training at long muscle lengths is not as dissimilar as you might assume to full range of motion training with constant - load, free weight exercises.

Most other types of external load, including those that add bands and chains to barbells, reduce the size of the peak contraction at long muscle lengths and increase it at shorter muscle lengths.

Factors that shift the angle of peak torque to longer muscle lengths after normal strength training include increases in neural drive at long muscle lengths, increases in normalized fiber length, specific gains in regional muscle size, and increases in muscle stiffness.

Similarly, isometric training at short muscle lengths improves strength at that joint range of motion, and only improves strength very slightly (if at all) at longer muscle lengths.

Alegre et al. (2014) reported that fascicle length remained unchanged in both groups, even though there was a change in the angle of peak torque in the group that trained at long muscle lengths.

Exploring the EMG amplitude of the hamstrings during the Nordic hamstring curl, Iga et al. (2012) found that EMG amplitude of the hamstrings was higher when the knee was extended than when the knee was flexed, indicating that the exercise trains the hamstrings at long muscle lengths.

In contrast, isokinetic training failed to improve torque at short muscle lengths (35 and 45 degrees), and also failed to increase EMG amplitude at long muscle lengths (85 degrees).

Comparing the effects of eccentric training at long and short muscle lengths, Guex et al. (2016) found that muscle fascicle length increased in both groups, but the increase was greater in the group that trained at long muscle lengths than in the group that trained at short muscle lengths (9.3 % vs. 4.9 %).

Increases in muscle fascicle length are known to occur after training at long muscle lengths (McMahon et al. 2014a), and this may lead to us observing greater increases in regional muscle size (Franchi et al. 2014).

Although both types of external load were variable, the machine knee extension would still have involved a larger contraction at longer muscle lengths than the isokinetic device.

On the other hand, regional hypertrophy (but not always muscle fascicle length) seems more important than changes in joint angle - specific neural drive for the joint angle - specific gains in strength after isometric training at long muscle lengths (Alegre et al. 2014; Noorkõiv et al. 2014).

Free weights and other constant loads (even those involving machines) during most common exercises produce a peak contraction at long muscle lengths (there are some exceptions).

Since strength is specific, then: strength training of the hamstrings at long muscle lengths, and the quadriceps and gluteus maximus at short muscle lengths, should lead to superior gains in sprinting performance than strength training at other joint angles.

Sprint running ability seems to be mainly determined by the ability of the hamstrings to absorb energy at long muscle lengths, and of the hip extensors (gluteus maximus, adductor magnus, and hamstrings) and hip flexors to perform concentric work at high velocities while operating at short muscle lengths, all in a horizontal direction.

Indeed, it is generally observed that anteroposterior exercises usually cause a peak contraction to occur at a short muscle length, while axial exercises more commonly produce their peak contraction at long muscle lengths.

Mornings in Bodley, drowsing among the worn browns and tarnished gilding of Duke Humphrey, snuffing the faint, musty odor of slowly perishing leather...; long afternoons, taking an outrigger up the Cher, feeling the rough kiss of the sculls on unaccustomed palms, listening to the rhythmical and satisfying kerklunk of the rowlocks, watching the play of muscles on the Bursar's sturdy shoulders at stroke, as the sharp spring wind flattened the thin silk shirt against them; or, if the day were warmer, flicking swiftly in a canoe under Magdalen walls and so by the twisting race at King's Mill by Mesopotamia to Parson's Pleasure; then back, with mind relaxed and body stretched and vigorous, to make toast by the fire.
