aspect of the anterior–superior iliac spine to the distal tip of the ipsilateral medial malleolus. To calculate the composite score, the sum of maximum reaches in each of the 3 directions was divided by 3 times the leg length. 3 Strength Testing Peak isometric hip external rotation, hip abduction, and

would be a significant, moderate correlation between hip abduction strength and hip adduction excursion, which was supported by our results. While we cannot say definitively without electromyography (EMG) measurements, the gluteus medius was likely recruited during the hip abduction strength test. The

availability for competition. 4 Recent research and technological advances have increased the number of tools available to assess constructs of fitness and fatigue. These tools include submaximal heart rate tests, 5 countermovement jumps (CMJs), 6 lower limb muscular strength tests, 7 and perceptual

moderate to vigorous physical activity and had lower daily step counts, which are variables that have a direct effect on cardiovascular health. Almeida et al 2 evaluated the cardiovascular system via VO 2 max and ventilatory thresholds, as well as a knee function questionnaire, isokinetic strength test

lateralis (VL), and rectus femoris (RF) muscles during the isometric strength test, and measured each muscle activity in 3 different ankle positions. The muscle activity recordings were obtained by bipolar circular surface electrodes (Ag/Cl; 0.8 cm diameter) placed on each muscle at a fixed interelectrode

rest. The baseline (pre) tests were then conducted at the following order: NONDOM hip-flexion passive ROM (pre-ROM) and NONDOM hamstrings isometric strength testing (pre-MVIC). Following the baseline tests, one of the intervention protocols was performed: Static stretching: the SS protocol consisted of

with the exception of a smaller field of view (250 × 250 mm) and commensurately higher resolution. 19 Due to the smaller field of view for the intrinsic foot muscles, a Siemens 4-channel large flex coil was utilized to increase signal-to-noise ratio. 19 Four-Way Ankle Strength Testing Ankle strength

Theoretically, during the test, the designated primary mover muscle should have the highest level of activity compared with the secondary mover. During SA (primary mover) strength testing, it is difficult to isolate the SA muscle from

shoulder rotators imbalance. 17 – 19 These imbalanced shoulder rotators could not stabilize the humeral head to the center of glenoid, which contributes to increase the risk of impingement. 20 Isokinetic muscle strength testing is commonly used to evaluate eccentric and concentric peak torque of the
