Aerobic Training Adaptations

Anaerobic training and aerobic training are categorized as a physical activity based on the duration of full-out exercise and the corresponding energy transfer systems utilized. Each type of excersize will produce its own set of training reactions in the body and to the body .

Aerobic - There are three significant adaptations associated with the constant performance of aerobic training. Aerobic training usually produces an increase in functional capacities related to oxygen transport and use in the body. Endurance training produces significant increases in maximal oxygen consumption (VO2max). Maximal oxygen consumption is an indicator of the level of cardiovascular , neuromuscular , and pulmonary functions.
Cardiovascular adaptations to this type of training are cardiac hypertrophy.
No improvement in VO2max ,or submaximal exercise heart rate and stroke volume occur with normal resistance training though there may be a minor increase in blood volume. Resistance training puts significant localized stress on specific muscles but produces minimal aerobic metabolic demand.
Strength training create muscle hypertrophy. The increase in muscular force generated in strength training stimulates the increased protein synthesis producing increases in muscle fiber size. This hypertrophy happens ususally in the fast-twitch muscle fibers that are activated with resistance training. Ligaments and tendons also become stronger and thicker due to resistance training.Training increases the resting levels of anaerobic substrates such as PCr,ATP, glycogen and free creatine
The increase in total contractile protein and energy substrates in resistance trained muscle fibers occurs without a parallel increase in capillarization, volume of mitochondria, or number of mitochondrial enzymes. In fact the ratio of contractile protein volume to mitochondrial/enzyme volume actually
