Table 3.
Hormone concentration (GH - growth hormone, T- testosterone, C - cortisol, I - insulin) in control subjects (CG), athletes with normal heart dimension (LVN), and athletes with heart hypertrophy (LVH). Data are means (±SD).
| VARIABLE | CG (n = 14) | LVN ( n = 15) | LVH (n = 15) |
|---|---|---|---|
| GHR [ng·mL-1] | .3 (.2) | .6 (.5) | .5 (.4) |
| GH MAX [ng·mL-1] | 16.5 (7.4) | 15.7 (6.2) | 16.3 (6.1) |
| TR [nmol·L-1] | 14.5 (3.0) | 14.6 (5.6) | 11.1 (4.4) *# |
| T MAX [nmol·L-1] | 22.4 (7.2) | 17.1 (6.2) | 13.9 (5.4) * |
| CR [nmol·L-1] | 390.4 (119.2) | 413.2 (81.9) | 442.2 (111.6) |
| CMAX [nmol·L-1 | 513.6 (123.6) | 442.6 (188.1) | 583.5 (117.7) # |
| IR [μlU·mL-1] | 8.3 (4.3) | 8.0 (4.6) | 8.0 (3.2 ) |
| I MAX [μlU·mL-1] | 9.5 (4.9) | 13.7 (4.1) | 12.6 (6.3) |
Subscript R indicates resting values, subscript MAX indicates values reached at maximal exercise intensity.
