Insights into the skeletal muscle characteristics of three southern African antelope species.

Kohn TA - Biol Open (2014)

Bottom Line: Overall, all three species had high oxidative and glycolytic capacities, but species differences were found.This study confirmed large variation in oxidative capacities within a single fibre type, as well as overlap between the fibre types with no distinct differences between the three species.The fibre type profile of each species is discussed and confirms some of their physical attributes and capabilities.

Frequency distribution plots (expressed as a percentage of the total number of fibres) of the oxidative capacity (optical density (OD)) from mountain reedbuck, blesbok and kudu Vastus lateralis muscle.Each bar was calculated as the number of fibres that obtained OD values in a specific range (e.g. from 0.70 to 0.79 OD).

f03: Frequency distribution plots (expressed as a percentage of the total number of fibres) of the oxidative capacity (optical density (OD)) from mountain reedbuck, blesbok and kudu Vastus lateralis muscle.Each bar was calculated as the number of fibres that obtained OD values in a specific range (e.g. from 0.70 to 0.79 OD).

Mentions: The oxidative capacity of each muscle fibre was quantified by determining the optical densities (OD) from the NADH stains (Fig. 2M–O) and the frequencies presented graphically (Fig. 3). The highest oxidative capacities were recorded in the type I and IIA fibres, followed by the type IIAX and type IIX fibres. The presence of oxidative type IIX fibres was also found in all three species (labelled Xo, Fig. 2M–O). There was a wide variation in oxidative capacities between and within the individual fibre types from the three species. The range was especially large for type IIA and type IIX fibres. Mountain reedbuck did seem to have an overall lower oxidative capacity compared to that from kudu and blesbok, but this was not statistically significant.
