Conley, Michael S., Jeanne M. Foley, Lori L. Ploutz-Snyder, Ronald A. Meyer, and Gary A. Dudley. Effect of acute head-down tilt on skeletal muscle cross-sectional area and proton transverse relaxation time. J. Appl. Physiol.81(4): 1572–1577, 1996.—This study investigated changes in skeletal muscle cross-sectional area (CSA) evoked by fluid shifts that accompany short-term 6° head-down tilt (HDT) or horizontal bed rest, the time course of the resolution of these changes after resumption of upright posture, and the effect of altered muscle CSA, in the absence of increased contractile activity, on proton transverse relaxation time (T2). Average muscle CSA and T2 were determined by standard spin-echo magnetic resonance imaging. Analyses were performed on contiguous transaxial images of the neck and calf. After a day of normal activity, 24 h of HDT increased neck muscle CSA 19 ± 4 (SE)% ( P < 0.05) while calf muscle CSA decreased 14 ± 3% ( P < 0.05). The horizontal posture (12 h) induced about one-half of these responses: an 11 ± 2% ( P < 0.05) increase in neck muscle CSA and an 8 ± 2% decrease ( P < 0.05) in the calf. Within 2 h after resumption of upright posture, neck and calf muscle CSA returned to within 0.5% ( P > 0.05) of the values assessed after a day of normal activity, with most of the change occurring within the first 30 min. No further change in muscle CSA was observed through 6 h of upright posture. Despite these large alterations in muscle CSA, T2 was not altered by more than 1.1 ± 0.6% ( P > 0.05) and did not relate to muscle size. These results suggest that postural manipulations and subsequent fluid shifts modeling microgravity elicit marked changes in muscle size. Because these responses were not associated with alterations in muscle T2, it does not appear that simple movement of water into muscle can explain the contrast shift observed after exercise.

Lumbar Multifidus Muscle

BACKGROUND: The multifidus muscle is located near the spine and controls the erection of the spine and stabilization during movements of the spine and extremities, and assists in all other spinal movements. Differences in paraspinal muscles between sides and levels, particularly in he multifidus, have been proposed as possible indicators of low back pain or spinal pathology. OBJECTIVE: This study aims to examine the cross-sectional area of the lumbar multifidus muscle at L4-L5 vertebral levels on ultrasound images of athletes in Olympic-style weightlifting, judo athletes and sedentary individuals. METHODS: This study included asymptomatic male athletes (athletes in Olympic-style weightlifting, n= 17, age: 19.24 ± 1.88, judo athletes, n= 17, age: 19.18 ± 1.23) and sedentary individuals (n= 17, age: 19.88 ± 1.31). The cross-sectional area of lumbar multifidus muscles was assessed bilaterally at the L4-L5 segments level in prone and using ultrasound imaging. RESULTS: Lumbar multifidus muscle cross-sectional areas of athletes in Olympic-style weightlifting and judo athletes were larger than those of sedentary individuals (p< 0.004). No asymmetric development was observed in cross-sectional areas of right-left lumbar multifidus muscle at L4-L5 levels of athletes in Olympic-style weightlifting and sedentary individuals (p> 0.008). The cross-sectional areas of the right and left lumbar multifidus muscle at L5 segment of individuals in judo athletes was found to be asymmetrical (p< 0.008). CONCLUSION: Our study shows that the cross-sectional areas of athletes in Olympic-style weightlifting and judo athletes are larger than that of sedentary individuals. The difference in the cross-sectional area of the lumbar multifidus muscle of athlete and sedentary groups might be said to result from hypertrophic effect of trainings of these athletes on the cross-sectional area of the lumbar multifidus muscle.
