Had some time after class on Wed so I hit the stairs at the stadium. Was sore for days after last week's session so this was better. Cool clear fall weather, in the 60ºs.
Hoka Rocket x2s on
stretches, drills
11 X stadium stair sprints
Hard but better than last time. Might have done a few more but ran out of daylight. Stair seem to actually help my foot. Feels better the day after. Maybe because stairs force me to dorsiflex the foot more and use more calf.
Maybe I'll continue this every week.
143.1 lbs after workout.
What is the approximate work-rest duration for each sprint? Are you walking back to the bottom?
ReplyDeleteThis study compared markers of inflammation and metabolic stress for swimmer sprints and running sprints and concluded that recovery inflammation was similar but running sprints has more metabolic stress than swimming sprints. So there may be something to your intuitive reasoning that running sprints is somehow unique in its physiological impact. https://onlinelibrary.wiley.com/doi/abs/10.1111/sms.13046
ReplyDeleteSo this is also a data point to not use the same protocols for cycling to develop tolerance for running. In other words don’t match your sprint duration, rest periods and number of repeats exactly. For instance in the posted study how many more swim sprints would it take to match the 2 hr later metabolic demand? 20 percent more? 50 percent more?
ReplyDeleteThere was an old rule of thumb for distance runners that 40mins running equated to 60mins of cycling. I have also seen 60/90.
ReplyDeleteIf you do a Chat GPT on interval running versus interval cycling you will see some suggestions. No doubt this can be done for swimming.
As I have said previously non-running intervals are of little value for sprinters. With the possible exception of `slow` 400m runners.
ReplyDeleteIn the off-season period, especially for the aging athlete with structural issues, non running intervals provide more specific system wide adaptation than non running steady state training. Some of these specific differences in adaptation include muscle fiber characteristics, improved buffer capacity and ability to prevent ionic and metabolic perturbations, specific heart adaptations due to the repeated higher pressures experienced during short bursts of activity. Of course running is preferred but most aging athletes (or non athletes for that matter) have diminishing ability to tolerate running due to wear and tear on the skeletal system.
