title: Comparative studies on fast muscle myosin light chains after different training programs.
abstract: Fast muscle myosin of guinea pigs exposed to different training programs was examined by means of SDS gel electrophoresis. The percentile distribution of the light chains was calculated. Training at 0.7 m/s and 5 degrees slope 20 min per day for 30 days caused a significant decrease in the DTNB light chains and a significant increase in the A2 light chains compared to the control group. In contrast, training at 0.4 m/s and 45 degrees slope caused a significant increase in the DTNB light chains and a significant decrease in the A2 light chains. These changes can be interpreted as a combination of muscle transformation and a shift of myosin isoenzymes.
