Yup, Was skating fairly regularly and playing hockey, until my health issues, some 4 yrs ago.
Planning to get back 'on ice' tomorrow... , with my granddaughter... Will be an adventure - 1 st time in 4 yrs...
I found skating to be a great compliment to cycling, and visa-versa. And hockey certainly requires strong core and upper body strength as well.
One thing about hockey, which doesn't come into play as much with other forms of skating (speed, general putzing around...) is the load on the groin area is intense.
If you're doing hockey properly, you're at a 'sprint' most of the time on ice, with frequent directional changes, stops, hard starts and all that puts a huge load on the groin.
Can't say for figures...
Great cardio and muscular load on legs is very complimentary to cycling. Edge changes and driving the stride are great for balance; especially working the outside edge.
An Hour of good hard skating would be closely equivalent to riding an hour; and same light load on the joints.
I highly recommend Skating and XC (both 'Classic' and modern skate techniques) for anyone in the great White North or anyone who might have a rink within range.
Skate On
