Context:

Ankle-dorsiflexion range of motion has often been measured in the weight-bearing condition in the clinical setting; however, little is known about the relationship between the weight-bearing-lunge test (WBLT) and both ankle kinematics and performance on dynamic postural-control tests.

Objective:

To examine whether ankle kinematics and performance on the Lower Quarter Y-Balance Test (YBT-LQ) are correlated with results of the WBLT using an inclinometer and tape measure.

Design:

Cross-sectional.

Setting:

University motionanalysis laboratory.

Participants:

30 physically active participants.

Interventions:

None.

Main Outcome Measures:

The WBLT was evaluated using an inclinometer and a tape measure. The reach distances in the anterior, posteromedial, and posterolateral directions on the YBT-LQ were normalized by limb length. Ankle dorsiflexion during the YBT-LQ was recorded using a 3-dimensional motion-analysis system. Simple linear regression was used to examine the relationship between the WBLT results and both ankle dorsiflexion and the normalized reach distance in each direction on the YBT-LQ.

Results:

The WBLT results were significantly correlated with ankle dorsiflexion in all directions on the YBT-LQ (P < .05). A strong correlation was found between the inclinometer measurement of the WBLT and ankle dorsiflexion (r = .74, r 2 = .55), whereas the tape-measure results on the WBLT were moderately correlated with ankle dorsiflexion (r = .64, r 2 = .40) during the anterior reach on the YBT-LQ. Only the normalized anterior reach distance was significantly correlated with the results for the inclinometer (r = .68, r 2 = .46) and the tape measure (r = .64, r 2 = .41) on the WBLT.

Conclusions:

Inclinometer measurements on the WBLT can be an appropriate tool for predicting the amount of ankle dorsiflexion during the YBT-LQ. Furthermore, WBLT should be measured in those who demonstrate poor dynamic balance.

The purpose of this study was to examine the financial investments factors in promoting mass sport in Korea and to determine their relative importance and investment priorities. This information would be a guideline for sports administrators' decision making in establishing investment policy. The Delphi technique (Dalkey, 1976) using 30 experts in mass sport administration and the Analytic Hierarchy Process method (Saaty, 1983) were used in this study. Six investment factors with 21 subfactors were derived. The top investment priority was given to the Sports Facilities factor, followed by the factors of Publicity, Leaders, Administrative Support, Voluntary Sports Clubs, and Programs. Investment priorities of subfactors in each factor were also discussed.
