Weight Training

I'm looking at "Exercise Physiology: etc." by McArdle Katch and Katch, 5th edition. On page 519 it says "Resistance Training Plus Aerobic Training Equals Less Strength Improvement. Concurrent resistance and aerobic training programs yield less muscular strength and power improvement than training for strength only." It suggests a 20 to 30 minute recovery period between aerobic and strength training, but cites the need for further research to support this. Four research papers are cited in this paragraph, two of which speak to this particular issue. It does not say whether the subjects are slackers or olympians. There is no claim that you shouldn't do both aerobic and strength training in the same day, just that you need a break in between. The claim is that the diminished training effect would apply to the strength-building aspect, but not necessarily the aerobic or athletic skill aspects. The book contains a few specific stats on swimming, such as VO2max versus speed, further categorized by stroke and fitness level. There are also parts devoted to the heat dissipation ability of water versus air, which is something that affects swimmers. Overall it is very broadly sports-targeted, however. I got the book mainly to understand the biochemical mechanisms by which macronutrients are converted to energy, and what the implications are to proper nutrition for active people. At the risk of stirring up controversy, nothing I have read in this book speaks favorably of low-carb diets, especially for athletes. (Don't blame the messenger!) There is something else I read which is likely to churn up discussion. On page 482, it says that in a study of collegiate swimmers, one group trained for 90 minutes daily, while another group trained for two 90 minute sessions daily. Surprisingly, no differences were observed in swimming power, endurance, or performance times. This suggests a point of diminishing returns exists around 90 minutes. Have at it....
