It's interesting how they matched the intensity. Because, in my opinion, dance is a sorta-kinda-like strength endurance training when you exert a modest loaded movement (say, 40%-50% of your bench press' 1RM) for 2-4 repetition and there are tens of these bouts. In calories spent such resistance exercise may match some endurance exercise but other effects can be dramatically different. Including, but not limited to, levels and utilization of brain-derived neurotophic factor. While endurance training increase BDNF level long term and modestly, the resistance exercise can effect a sharp 60%-90% increase at the end of training session, then drop to 40% of normal (to the person) level and slow recovery. This indicates overproduction of BDNF and its complete utilization of the body to build neurons everywhere.
