Cycling costs strength athletes less progression than running
Strength athletes who also do cardio training will lose less progression if they cycle than if they run on a treadmill. On the other hand, treadmill training gives a bigger decrease in body fat, writes Jeff Gergley of Austin State University in the Journal of Strength and Conditioning Research.
All groups trained their legs twice a week, doing leg extensions, leg curls and leg press. The first 3 weeks they did sets of 12 reps, then they did sets of 10 reps for another 3 weeks, and finally they did 3 weeks of sets of 8 reps.
The R group did nothing else. The RC group combined the strength training with cycling and the RT group combined it with running on a treadmill. The subjects did endurance training twice a week on the days that they didn't do strength training.
The intensity was 65 percent of the subjects' VO2max. For the first 3 weeks the RC and the RT groups trained for 20 minutes, then they trained for 30 minutes during the next 3 weeks and during the last 3 weeks they trained for 40 minutes.
The figure shows that the maximal strength increased most in the R group. The RT group made least progression and the RC group did a little better.
The fat percentage decreased most in the RT group and in the R group the least. Running simply costs more energy than cycling.
Perhaps we just have to accept that cardio training diminishes the progression you can make as a strength athlete. Whatever combination you choose, there will always be a trade off.
