The game of swimming is the pursuit of perfection: the pursuit of the right race. Has any swimmer ever achieved this feat? Perhaps Jason Lezak’s anchor leg within the 4x100m freestyle relay on the 2008 Beijing Olympics might make that declare, however that is only one out of the bulk. I believe most of us have by no means had an ideal race — even when I’ve a finest time, there’s at all times one thing I might have achieved higher, whether or not that’s doing yet another underwater kick off of every wall or not gliding into my end. There are various components that go into the execution of the right race — some we are able to management and a few we are able to’t. For instance: we are able to’t management how briskly our warmth goes to go, however we are able to management how we bodily and mentally put together ourselves for the race. All that preparation occurs at observe.
The truth is, there was a scientific examine performed just lately that examined the physiological and psychological calls for of cardio and anaerobic swimming. Physiological components embrace swim practices and elevate periods, whereas psychological components embrace a swimmer’s emotional state and stress stage. Each play an element in any size of race, however they hypothesized that the necessities can be completely different in an cardio versus anaerobic setting.
Anaerobic respiration is a mobile course of that doesn’t use oxygen. Within the swimming sense, anaerobic races are sprinting occasions just like the 50 and 100. Any such power conversion happens in a short time, however doesn’t final very lengthy. Inside forty-five seconds to 2 minutes, your physique will begin getting power from cardio respiration. This course of makes use of oxygen, so your cardio races are normally something over a 200. Physiologically, it’s clear that these two varieties of races would have completely different results on the physique; it’s the psychological half that intrigues me probably the most.
Once I was a sophomore in highschool, I developed actually unhealthy pre-race anxiousness. I might get up behind the blocks and my thoughts would race as I consistently readjusted my goggles: What if all my onerous work doesn’t repay? What if it hurts? What if I can’t end sturdy? By the point I lastly stepped up onto the blocks, I had no need to race anymore. I simply needed to place my heat jacket again on, go dwelling, and go to sleep for a really very long time. You may say that I used to be physiologically ready for these races — I did precisely what I used to be presupposed to do throughout observe, and extra — however I used to be removed from psychologically ready. Consequently, I used to be sliding backwards as a substitute of enhancing; despite the fact that I used to be coaching tougher than I had earlier than. The right race appeared increasingly out of attain, and I wasn’t certain what to do to get again on observe.
9 feminine and 11 male swimmers participated on this examine. All of them competed on the nationwide stage, had not less than 5 years of coaching expertise, and weren’t injured or taking any treatment. To find out the physiological features of cardio versus anaerobic races, the scientists took coronary heart price variability (HRV) exams to research the swimmers’ autonomic nervous system state. This method consists of coronary heart price, blood strain, and respiration, that are all concerned in anaerobic and cardio processes.
The scientists used a RESTQ-76 sport questionnaire to determine the psychological components. The questions on this check are used to self-report subjective, behavioral, bodily, and social features of restoration and stress. A few of the questions had been sport-specific whereas some weren’t. This check was achieved earlier than and after every cardio and anaerobic swim session, permitting the scientists to get a full image of the emotional well-being of their swimmers, inside and outdoors of the pool.
As for the cardio and anaerobic exams themselves, they had been achieved on consecutive days. The anaerobic check was accomplished first and consisted of a 50m freestyle dash at most effort. The workforce recorded the time it took and the speed of perceived exertion (RPE). For the cardio check, the swimmers did 5x200m swims of their main stroke, with 30 seconds of relaxation in between each. Throughout this set, the scientists had been measuring the swimmer’s velocity, their oxygen uptake, and their coronary heart price. From this information, they may calculate their maximal cardio pace (MAS) together with their RPE at that pace.
What they discovered was actually fascinating to me: Cardio efficiency is related extra with physiological options, whereas anaerobic efficiency is related to psychological. The scientists emphasised the significance of getting a nonstressful atmosphere for an anaerobic race, which may be the rationale I’ve been fighting executing an ideal race. My main occasion is the 100-yard backstroke, which is an anaerobic race. Because it was the occasion I cared about probably the most, I used to be at all times probably the most nervous earlier than hopping within the water. If a low-stress atmosphere is what makes a swimmer carry out the very best, then no marvel I wasn’t ready to try this. I used to be making a high-stress atmosphere for myself, whereas additionally in a high-pressure atmosphere. It was a recipe for catastrophe.
One thing else I discovered intriguing within the examine is that prime fatigue notion can be tied to a sooner time in an anaerobic race. As swimmers, everyone knows what it’s wish to really feel drained, and most of us are underneath the impression that if we’re drained or sore, then we are able to’t swim quick. In accordance with the science, it’s the other — we are able to nonetheless go quick if we really feel fatigued and possibly even sooner than if we’re fully rested. This solely applies for an anaerobic race, although. For an cardio race, the scientists discovered {that a} greater cardio efficiency was instantly correlated to a better autonomic nervous system activation. An athlete who had greater values within the HRV exams had a better MAS. This is smart because the cardio races are distance races the place stamina performs a a lot bigger position than in anaerobic races.
I began seeing a sports activities psychologist throughout my junior yr of highschool. Not solely did he give me the instruments to anchor my ideas within the second, he helped me unlock a confidence inside myself that I didn’t know I had. I believed that my mind would stop me from ever getting near reaching the right race; what I didn’t understand is that, if used accurately, it might change into the best device.
All through highschool I needed to interrupt a minute within the 100-yard backstroke. It was a milestone that stored slipping by way of my fingers, and I used to be beginning to suppose that I might by no means attain it. Nevertheless, two years after I began being attentive to my ideas, I did. That race was removed from excellent, nevertheless it was the closest I had are available a very long time. That’s the factor about pursuing an ideal race: every time you are taking a chip off the block, you’ll be able to’t assist however attempt to take one other one.
