D.P, can you please reply to MrThingyX's post. I always see you talking as the authority on cardio (because you do a lot of it being your qualification), but MrThingyX has come back with some valid responses to you and you seem to be purposefully ignoring it, whilst continue to beat your drum to other people's replies, with more opinion.
I simply didn't see his response.
Not really: cardio "fitness" (exercise and recovery capacity) is sport specific, with only relatively transferable gains between sports/activity types.
Tell that to any triathlete, decathlon athlete or any sports coach that get their athletes to do cross training. Cardio exercise result in increase heart volume, increased heart efficiency, increased capillaries, larger glycogen stores, improved fat metabolism, improved lung capacity, increased neuro-musclar control, improved mental strength to push hard, increased red-blood cell count,, increased mitochondria, increased blood plasma, weight control, etc., etc. These benefits a wide range of cardio sports. What does get specialized is the particular muscles to do each sport. So for me for example, I do a lot of running but a little swimming and cycling. I have the CV fitness to to cycle for hours and hours but my FTP is low so I simply don't have the speed of dedicated cyclist, I just don't have the quad muscles. Conversely good cyclists will do very well running, Lance Armstrong ran a sub-3 marathon with relatively little training, something which most running will never achieve in their life.
There is specialization, and if you really want to be the best of the best then dedicating the most time to 1 exercise is the best thing to do, but there is plenty of crossover from a cardio perspective. Its mostly technique and muscle strength/adaptions that don't crossover.
And an hour of very specific, limited Range of Joint Motion activity is actually what builds people up for IT band injuries, patellar tendinitis, shin splits and back pain.
Why?
Not necessarily; poor technique, poor form, poor training, poor recovery are all major factors. There is then just the physics of it, e.g. cyclist have a lower occurrence of leg injuries despite extremely limited motion because there are no impact forces compared to running. Swimming don't get leg or back injuries because they are weightless, but they are prone to shoulder injuries.
Because they limit the use of the hips and ankles, meaning the back has to compensate for the lack of mobility. Which is why elite cardio people (distance athletes) lift weights or go through full range of motion body weight "lifting."
I don't agree that its lack of mobility but I agree that athletes both can suffer such injuries and need to do some strength work to mitigate them. I am a big believer in strength training to improve my running. Runners often get hip issues, but that is from a combination of repeated impact forces, poor technique when tired, and muscular imbalances due to specialization. E.g., runners develop very strong calves and upper legs to enable them to propel them selves, but stability muscles from the core are less important for performance and so experience less adaption. This is why strength exercises are important.
Which is why weights and strength should always be part of a weightless routine. One of the reasons, anyway...
I agree, except you don't have to add weights and you don't have to do it in the gym. As Is aid earlier int his thread, I recommend doing some body weight exercises in your living room.
A typcial work out for me is soem combination of this:
1. Clams x 20
2. Lateral leg raises x 15-25
3. Donkey Kicks x 15-25
4. Donkey whips x 15-25
5. Fire hydrant x 15-25
6. Knee circles – forward x 15-25
7. Theraband balance x 15 repetitions with each leg
8. Standing hip flexor x 15
9. Standing hip abductor x 15
10. Hip hikes x 15
And other similar workout for core strength (various combos of planks, ab crunches, squats, jumps, pull ups). 2-3 times a week for 20-30 minutes helps tremendously. These things are all very safe, don't require special technique & training, won't cause muscular imbalances, can be done watching Netflix, and have a low injury risk.
