Abstract

The role of heredity in the response of maximal anaerobic capacities and skeletal muscle histochemical and biochemical characteristics to a 15-week cycle ergometer training program involving both continuous and interval work patterns was investigated in 14 pairs of monozygotic twins. The training program consisted mainly of series of ergocycle supramaximal exercises lasting from 15 s to 90 s and performed 4 and 5 times a week. The subjects were submitted to 10 s and 90 s all-out ergocycle tests to estimate maximal anaerobic alactacid (AAC) and lactacid (ALC) capacities, respectively. Muscle fiber types and creatine kinase (CK), hexokinase (HK), phosphofructokinase (PFK), lactate dehydrogenase (LDH), malate dehydrogenase (MDH), 3-hydroxyacyl CoA dehydrogenase (HADH), and oxoglutarate dehydrogenase (OGDH) activities were determined in a biopsy from the vastus lateralis. Training increased AAC, ALC, fiber type I proportion, MDH, HADH, and OGDH (P less than 0.05) and decreased fiber type IIb proportion and the PFK/OGDH ratio. No significant change was observed for CK, HK, PFK, and LDH. Large interindividual differences in the response to training were observed for all variables. However, intraclass correlations indicated that the extent of the response of ALC and CK, HK, LDH, MDH, and OGDH activities and of the PFK/OGDH activity ratio to training were significantly similar within pairs of twins. Although the role of heredity appeared absent for the changes in fiber type proportions and in anaerobic alactacid capacity, the present results suggest that the response of anaerobic lactacid capacity and most enzyme activities to high-intensity intermittent training is significantly determined by the genotype.

  • After aerobic training, monozygotic twin pairs showed greater similarity in VO2max gains than unrelated twin pairs.

    “pairs of identical twins had significantly more similar increases in VO2max than unrelated twin pairs after aerobic training in three papers in the mid-1980s (217, 421, 474).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
