As Menstrual health apps above, long term endurance training is likely to increase the adaptahions sectional area of Type I slow twitch muscle fibres and cause a possible transition from Type IIb fast twitch to the more oxidative Type IIa muscle fibre.
Short term detraining weeks is unlikely to result in muscular atrophy Houmard et al, whereas longer periods of detraining 8 weeksmay result in more significant levels of muscle atrophy Leger et al, ; Narici et al, and an increased transition from Type IIb to Type IIa muscle fibres Staron et al, As a result, the body becomes less efficient at utilising its fat stores placing a greater reliance on muscle glycogen during exercise at the same sub-maximal work rate Madsen et al, ; Moore et al, Blood lactate concentration is also an important measure of aerobic endurance.
Significant increases in blood lactate levels were noted by McConell et al. Although VO2max remained unchanged, running performance over 5 km significantly decreased. The authors concluded that training intensity should be maintained during a reduced training period. Progressive significant increases in blood lactate levels over a similar time period weeks were also reported by Neufer et al.
It was also reported that increases in blood lactate levels may stabilise over a more prolonged detraining period Coyle et al, Running economy relates to the metabolic cost of running at a steady state sub-maximal speed.
The lower the metabolic cost of running, the lower the energy required to move at a given speed and the better the endurance performance. Running economy has been associated with a number of different physiological, anthropometric, metabolic and biomechanical variables including a high proportion of Type I muscle fibres Saunders et al,improved biomechanics and more efficient techniques Jones, ; Saunders et al,increased muscle stiffness Saunders et al, and body height, limb dimensions and body mass Lucia et al, Houmard et al.
The results of this study indicate that the oxygen cost of running at a specific velocity of VO2max remains the same during a period of detraining. However, the decrease in VO2max and the other metabolic changes mentioned above are likely to mean that an athlete becomes less tolerant when exercising at the same work rate.
In this study, the participants took part in an initial 4 week training programme, after which, they were randomly assigned to a run group, elliptical group and a detraining group.
The elliptical training group experienced a 1. However, it should be noted that this study used previously untrained individuals. Interestingly, the authors reported no significant difference between the increases in VO2max of the deep water running group and the road running group.
This suggests that deep water running may be suitable for runners hoping to maintain VO2max at pre-injury levels. For those runners not able to take part in sport specific exercise, arm cranking may be a suitable way to help maintain VO2max or at least prevent a significant reduction.
An interesting study by Pogliaghi et al. Although this study was aimed at an older population, the results indicate that the both forms of aerobic training using different muscle masses — i. arms v legsproduced similar improvements in maximal and submaximal exercise capacity.
The authors of the study reported that approximately half of the improvements were specific to exercise mode i. increases in stroke volume and maximal cardiac output. In some cases, athletes may be able to simply reduce the workload rather than have a complete break.
The cyclists performed intermittent high intensity exercise or continuous low intensity exercise for 2 hours a day, 3 times a week. The authors reported no differences between the intermittent or continuous training protocols.
Although this study was principally looking at tapering strategies, it provides evidence that enforced time off possible as a result of injury should not always be viewed negatively provided low intensity exercise can be maintained.
There is no recipe for cross-training and it will depend on each individual and their goals. Maintaining intensity is the key factor for retaining previous training adaptations, or at least, delaying the effects of detraining. As I mentioned earlier, I think the take home message is to make any cross training as sport specific as possible in order to reduce the negative impact on aerobic endurance.
However, if this is not possible, VO2max can still be maintained but aerobic endurance will decrease. Bassett, D. Limiting factors for maximum oxygen uptake and determinants of endurance performance.

| Top bar navigation | If anything, it seems aerobic endurance has even improved a little, or in other words, my heart rate is similar or slightly lower at a given pace, with respect to before getting injured:. Today August 24th, , after almost 6 weeks since the injury, I did the first proper workout in a while 3 x m , and even during this session, I was running similarly to before the injury. While the session in July was a bit of a bad day, these sessions are very similar and the pace I could hold today is pretty good for my standards. Based on the data above, we could say that indeed cycling a fair amount over the past month allowed me to maintain my VO2max and aerobic efficiency. What I could not maintain during this period of cross-training is my ability to endure sustained efforts, from a muscular point of view. I feel really fatigued and sore in my legs all the time, and I tire very quickly with respect to before. Normally I would do 4 or 5 reps in this session, but I had to stop today. Last Sunday I also went out at marathon intensity and had to call it a day after only 12 km at intensity and 17 km total. Normally I would do twice that 35 km with 25 km at intensity. It was interesting to see how some aspects of fitness were almost perfectly maintained - even when quite different aspects such as speed near threshold and heart rate and low intensities - which are as good as before, while other aspects, such as durability, have decreased quite dramatically. As mentioned above, this might be amplified by the fact that economy and durability are limiters for me even when I run a lot, and others might experience it differently or less. Overall, I enjoyed this experiment, it was a good excuse to learn from the scientific literature on de-training and cross-training, and I always enjoy a bit of self-experimentation. I also believe I am slowly picking up a bit of passion for another sport, which is a good thing, and I am looking forward to doing more cycling in the future. This was also a good reminder that it is always hard to start something new when we are so bad at it and the conditions might not be ideal. Giving it enough time our relationship with it might change dramatically. As running remains my priority, and my limiters i. economy and durability are heavily impacted by how much I run as shown once again by the past 6 weeks , my goal is to keep running as much as I can. If I had a different physiology, maybe lacking in VO2max and good in running economy, I would probably consider quite a different plan, with more cycling and more high-intensity cycling ideally indoor for safety reasons to push VO2max higher and reduce injury risk. However, in my case, I have to run as much as I can to keep improving in terms of economy and durability, while VO2max is quite high for my level. I do have of course to balance this with the difficulty of staying injury-free, which we all know, is not as easy for runners. Having an alternative works well for someone who tends to behave obsessively see later. This type of training should help in terms of fitness, takes little time and has minimal or no impact on running in my experience. I will start by doing it the same day I do a hard running workout, so that I do not compromise running. This would be the only activity that aims at maintaining cycling fitness more than helping running. The goal with this plan would be to 1 reduce injury risk by not running every day, which had worked well before I abandoned it in favor of more volume 2 maintain some level of cycling fitness all year round, so that I can enjoy a good adventure on the bike here and there. cycling after a hard race, instead of running even more, which was what caused this injury , is probably a better way to manage my health and long term performance. I suspect I might not be alone here. Marco holds a PhD cum laude in applied machine learning, a M. cum laude in computer science engineering, and a M. Including some running, walking, or strength training to help bone-mass or add muscle mass. Community — meet more people when you do different sports. You might have gym friends, run friends, and volley-ball or yoga friends! Ego — no judging or basis for comparison when in a new sport. Efficiency — If you are in an unfamiliar sport you will not be as efficient, which is a great feature when trying to build work capacity e. burn more calories. Running is often held up as an efficient workout due to the time required to get out the door and simply that it does not have the mechanical efficiency of the bicycle. Alex Hutchinson Outside Article on poles. Bonus 11 — Sampling — You might find you enjoy, or that you are more proficient in another sport. As we age, as we move to new locations and as our time available shifts the sports we prefer can change. So cross-training helps you find new sports to enjoy! We get it and we are here for you! You like to do your goal sport and you might have some injuries that prevent you from doing things like running and might not have access to great terrain for xc-skiing and other common modes. Walking is a great thing to start with and is good for so many reasons mobility, ability to do errands or talk on the phone, get outside, low-level cardio that is missing in many athletes, no special equipment, do it anywhere! Combine indoor Cycling with Strength — For those who train indoors on the bike is to jump off the bike and do some strength type movements every minutes during your rides. This will mix up those long sessions on the bike and also help get more muscle mass working. For many clients, this can make the difference between 1-hour max indoor time to 90 or even minute sessions. Before you go, check out our book, Becoming A Consummate Athlete.

To date, however, there have been only a few scientific studies which have examined the effects of combined cross-training on endurance performance. In possibly the first attempt to investigate the possible benefits of cross-training, Pate et al. After 4 wk of this cross-training, the leg-trained athletes had retained or actually increased their cycling capacity. However, those individuals who trained the upper body had simply detrained. The results of this study imply that pure cross-training that is, training another body part from that which is used in the athletes primary activity or event is useless for retention of training effects. In the most recent and perhaps well-controlled study, Mutton et al. After 5 wk of training, there were improvements in both the run-only and the cross-trained athletes for one mile time 21 vs 18 s , m performance 1. Although there were no differences in any of the performance measures between the two groups, Mutton et al. It is difficult to see how such a conclusion was warranted, when the effects of cross-training on performance never exceeded those induced by specific training. In addition, the principles of specificity of training are likely to have greater significance for well-conditioned competitive athletes compared to the moderately-trained recreational subjects who participated in this study. Both scientific evidence and anecdotal reports overwhelmingly indicate that the best way to retain a training effect and improve subsequent performance is to continue using the primary mode of activity in which the athlete wants to participate, or an exercise that is very similar in terms of neuromuscular recruitment. Observing the world's top athletes show clearly that the best marathon runners do not undertake any of their training in the swimming pool. Conversely, the best swimmers certainly wouldn't be advised to take to the road and start serious running! Thus, cross-training is somewhat of a misnomer; and for the serious single-event athlete, something best left to those multi-event sports that require competitors to be proficient in more than one discipline. A common but slightly different example of cross-training is where swimmers undertake dry-land training usually cycling or running in addition to their already huge swimming load, in an attempt to control their body fat levels. |
Cross-training adaptations -
One piece of indirect evidence to indicate that neural adaptations accompany resistance training comes from the phenomenon of 'cross education', which describes the strength gain in the opposite, untrained limb following unilateral resistance training. Since its discovery in , subsequent studies have confirmed the existence of cross education in contexts involving voluntary, imagined and electrically stimulated contractions.
The cross-education effect is specific to the contralateral homologous muscle but not restricted to particular muscle groups, ages or genders. A recent meta-analysis determined that the magnitude of cross education is approximately equal to 7.
While many features of cross education have been established, the underlying mechanisms are unknown. This article provides an overview of cross education and presents plausible hypotheses for its mechanisms.
Two hypotheses are outlined that represent the most viable explanations for cross education. In a broad sense, adaptation means the adjustment of an organism to its environment. If the environment changes, the organism changes to better survive the new condition. Accommodation : states that the response of a biological object to a constant stimulus decreases over time.
Meaning that if the same training exercises completed at the same intensity is done repeatedly. In the beginning there is a positive change but over time the change diminishes. Effects of detraining on endurance capacity and metabolic changes during prolonged exhaustive exercise.
