Exercise Technique: Reverse Lunge Into a Step-Up

Hip-muscle activation during the lunge, single-leg squat, and step-up-and-over exercises.

CONTEXT Functional exercises are often used in strengthening programs after lower extremity injury. Activation levels of the stabilizing hip muscles have not been documented. OBJECTIVE To document the progression of hip-muscle activation levels during 3 lower extremity functional exercises. DESIGN Cross-sectional. SETTING Laboratory. PARTICIPANTS 44 healthy individuals, 22 women and 22 ...

Functional assessment using the step-up-and-over test and forward lunge following ACL reconstruction.

This investigation compared lower extremity function of a control group and a group of patients who underwent anterior cruciate ligament (ACL) reconstruction using a repeated measures post-test only control group design. The ACL reconstruction group consisted of 18 patients at least 6 months postoperative (mean 58+/-19 weeks) and the control group consisted of 18 healthy, recreationally active ...

Reliability and minimal detectable change of three functional tests: forward-lunge, step-up-over and sit-to-stand

[Purpose] To examine the intrasession and intersession reliability and the absolute reliability of three functional dynamic tests-forward-lunge, step-up-over and sit-to-stand tests-using computerized dynamic posturography. [Subjects and Methods] An intra-test and test-retest, repeated measure study was designed. Forty-five healthy subjects twice carried out the forward-lunge test, step-up-over ...

Validation of a modified one-step rebreathing technique for measuring exercise cardiac output.

A modification of the Farhi one-step rebreathing technique (1) is described for determining submaximal exercise cardiac output (Q). Factors critical in the estimation of Q are initial rebreathing bag volume and constant bag volume during the maneuver. By substituting a high flow rate analyzer (500 ml.min-1) for the recommended low flow rate mass spectrometer (60 ml.min-1), adding a recirculatio...
