Classic indeed…Back in 1980, no one really imagined that one would interfere with the other on such a deep level. Obviously, whatever time you spend endurance training takes away from strength training, but this goes even beyond that.

Check out the summary below (click for full article).

The purpose of this study was to determine how individuals adapt to a combination of strength and endurance training as compared to the adaptations produced by either strength or endurance training separately. There were three exercise groups: a strength group (S) that exercised 30–40 min [per] day, 5 days [per] week, and endurance group (E) that exercised 40 min [per] day, 6 days [per] week; and an S and E group that performed the same daily exercise regimens as the S and E groups. After 10 weeks of training, VO2max increased approx. 25% when measured during bicycle exercise and 20% when measured during treadmill exercise in both E, and S and E groups. No increase in VO2max was observed in the S group. There was a consistent rate of development of leg-strength by the S group throughout the training, whereas the E group did not show any appreciable gains in strength. The rate of strength improvement by the S and E group was similar to the S group for the first 7 weeks of training, but subsequently leveled off and declined during the 9th and 10th weeks. These findings demonstrate that simultaneously training for S and E will result in a reduced capacity to develop strength, but will not affect the magnitude of increase in VO2max.

With empathy being measured here on a scale of 1 to 5 (“strongly disagree” to “strongly agree”), this means that the drop in empathy still leaves college kids at about 2.5-3, i.e. “neither agree nor disagree”. Not exactly an inspiring result, but no one should be freaking out at this point (cough-Fox News-cough)

Konrath discusses why this is not a total crisis, in this article, saying:

…just because empathy is declining on average, does not mean that each individual is low in empathy. To accuse an entire generation of low empathy is not very kind, nor is it accurate…American college students are not the most prototypical Americans. They are richer, whiter, more female, and in our sample at least, about 20 years old on average…Violent criminal acts such as murder, rape, robbery, and aggravated assault have all shown steady, marked decreases from the early 1990s to the late 2000s. This is the opposite of what we would expect if empathy was ‘under siege.'
