Sentences with phrase «knee joint rom»

There was a significant (ρ < 0.01) negative correlation between dependent variables; subjects» quadriceps force and knee joint ROM pretest for foam rolling and control conditions.

The second objective was to determine if foam rolling improves knee joint ROM.

Thus, to assess knee joint ROM, each participant was asked to conform a kneeling lunge position so that the right hip was stretched to the point of discomfort followed by the participant's right knee being passively flexed to the point of discomfort.

Subjects» quadriceps maximum voluntary contraction force, evoked force and activation, and knee joint ROM were measured before, 2 minutes, and 10 minutes after 2 conditions: (a) 2, 1 - minute trials of SMR of the quadriceps via a foam roller and (b) no SMR (Control).

In future studies that test knee joint ROM for the quadriceps, it may be optimal to recruit participants who are inflexible.

After foam rolling, subjects» quadriceps force and knee joint ROM no longer correlated at 2 and 10 minutes (Figure 7, for clarity only the foam rolling correlations are shown), whereas after the control condition, the significant (ρ < 0.05) negative correlation between quadriceps force and knee joint ROM remained at 2 and 10 minutes.

We hypothesized that there would be an increase in knee joint ROM and a decrease in quadriceps force output.

Perhaps the high force mechanical stress application (i.e., a combination of body mass and high - pressure foam rolling) performed in this study was enough to induce a gel - like state in the fascia leading to increased soft - tissue compliance and subsequently greater knee joint ROM.

The most important findings presented are as follows: (a) There was a significant increase in knee joint ROM at 2 minutes postfoam rolling (12.7 %) and 10 minutes postfoam rolling (10.3 %) of the quadriceps muscles, (b) there was no significant changes in voluntary or evoked muscle properties after foam rolling, and (c) after foam rolling, the negative correlation between ROM and force production no longer existed.

One potential limitation in the study was the difficulty to find a knee joint ROM test for knee flexion.

On the one hand, some trials have reported that the hamstrings EMG amplitude is greatest in the middle of the overall knee joint ROM (Worrell et al. 2001; Higashihara et al. 2010a).
