TABLE 2.
Descriptive data, nutritional status, and multifidus muscle CSA by gender.
| Age (Yr) | Height (in) | Weight (lb) | BMI | %BF | CSA Left | CSA Right | |
|---|---|---|---|---|---|---|---|
| Male | 31.88 (6.53) | 70.50 (2.56) | 175.75 (24.06) | 24.81 (2.53) | 16.06 (7.03) | 7.59 (1.67) | 7.57 (1.38) |
| Female | 32.76 (13.55) | 65.29 (2.64) | 145.53 (30.44) | 23.88 (4.30) | 26.08 (6.79) | 6.05 (0.76) | 5.97 (0.73) |
| Total | 32.48 (11.62) | 66.96 (3.56) | 154.88 (31.31) | 24.18 (3.80) | 22.88 (8.24) | 6.54 (1.32) | 6.48 (1.39) |
Values are means and (SD). The averaged (left and right) L5 multifidus muscle CSA for male subjects (mean = 7.58 cm2, SD = 1.51) was larger (p = 0.002) than that of female subjects (mean = 6.01 cm2, SD = 0.70). No differences were noted for left and right multifidus muscle CSA (p = 0.67). %BF = percent body fat. CSA = cross-sectional area of multifidus muscle at the L5 level.
