Increasing work capacity/ decreasing recovery time

No, I'm right. A study for that treadmill is never going to be done on athletes, because there is simply no way to justify its use. It is that ridiculous and no half serious athlete would compromise their condition/training to be a part of that study.

 

Yeah and I once invented a skateboard with a jetpack, the president asked for one but I said no, they're just for me and my brother and I can't sell them unless it's for a billion dollars. (I wonder if anybody is interested in my product now...)

 

A Synopsis of the PhD entitled: The Biomechanics of
and the Physiological Responses to Vertical Treadmill
Exercise

Rationale
There is an increasing incidence of sport- related overuse injuries which are
attributable to an increased training volume, longer competitive season resulting in
a reduced recovery period (Emery, 2003). In fact, over a third of injuries
throughout the soccer season are related to overuse (Hogan and Gross, 2003).
Overuse injuries of the lower extremities result from high volumes of impact
loading of joints and muscles during prolonged periods of over ground running
(Hreljac, 2004). The vertical treadmill is a new low-impact exercise mode designed
for the physical conditioning and the rehabilitation of athletes.
Vertical treadmill exercise requires a running action in a recumbent posture on a
vertically hung, non-motorised treadmill whilst the limbs are supported with
overhanging resistance cables. The low-impact nature of vertical treadmill exercise
reduces the likelihood of overuse injuries and could prevent the loss of physical
fitness during the injury rehabilitation process. In addition, there was plenty of
anecdotal evidence to support the use of the vertical treadmill for strength and
conditioning and rehabilitation programmes in many sports including football,
middle distance running, boxing and triathlon. For example, an elite 800 m junior
athlete (16 years of age) supplemented running training with vertical treadmill
exercise 3 times per week for 6 months and his improved 800 m run time by 14.3 s
and a 32 year-old female elite triathlete improved her sprint triathlon time (same
triathlon event) by 7 minutes following 6 months of vertical treadmill exercise only.
This evidence was strong enough to warrant a fully-funded PhD student and
research programme to undertake independent, scientific investigation.
The research aims and objectives
This thesis aimed to determine the efficacy of the vertical treadmill as an exercise
mode for physical conditioning in a physically active population. To achieve this
aim, three major objectives were proposed:
1. Identify the lower limb kinematics and muscle recruitment patterns during
vertical treadmill exercise in different postures and intensities in a physically active
population.
2. Identify the acute responses of the cardiorespiratory system and metabolic
demands of vertical treadmill exercise during varying intensities in a physically
active population.
3. Identify the chronic adaptations of the cardiorespiratory, muscular and
neuromuscular systems to a training intervention on the vertical treadmill in
physically active population.
Kinematic and neuromuscular recruitment patterns during vertical treadmill
exercise
The kinematics and neuromuscular recruitment patterns of the lower extremities
were determined in different postures (supine, 40º and 70º) and at different
intensities (perceived low, moderate and high intensity) with a view to informing
the construction of an appropriate conditioning programme and rehabilitation
programmes. Irrespective of posture and intensity, the hamstrings and
gastrocnemius muscles were active to draw the leg downwards against the
resistance cables and the rectus femoris and tibialis anterior were active in the
upward phase. The vastii muscles were not active (remedied by attaching the
resistance straps above the knee on the latest version of the vertical treadmill).
The supine posture placed a higher demand on the hamstrings and postural
musculature when compared with the 40º and 70º postures thus demonstrating a
progression of the exercise demand by simply altering the participants’ posture.
The vertical treadmill also demonstrated a similar kinematic running pattern and
range of motion at the ankle, hip and knee to that of over ground ambulation. The
early indications were that the vertical treadmill places a high demand on the
hamstrings and hip musculature and imitates over ground ambulation without the
impact loading and the associated injury risk. Therefore the vertical treadmill might
be useful in supplementing training and rehabilitation programmes.
Acute physiological responses to vertical treadmill exercise
The physiological responses to submaximal (perceived low, moderate and high
intensity) and maximal vertical treadmill exercise were determined to inform the
construction of an appropriate training programme. The physiological responses
revealed a lower maximum heart rate and O2peak when compared with conventional
treadmill running. Therefore the vertical treadmill has a lower exercise demand
than over ground running, thus the vertical treadmill can be used by the unfit as
well as elite athletes. Despite a lower heart rate and O2peak, the rates of perceived
exertion for the vertical treadmill were greater than for conventional treadmill
running. The perception of a harder exercise mode was probably due to the
unfamiliarity with the nature of the exercise. With some training the perception of
effort and the exercise demand might reduce.
Sprint interval treadmill on the vertical treadmill exercise
The effect of a 6-week sprint interval training (SIT) (4-6, 30 s all-out efforts with
4.5 min recovery, 3 times per week) on O2max., maximum anaerobic running power
and responses to submaximal running on a conventional treadmill were compared
with SIT performed over ground (20 m shuttle sprints) and control group. The key
findings of this study were that over ground and vertical treadmill SIT increased
the anaerobic running power by 4% each and that O2max., increased by 4% and 6%,
respectively. Therefore vertical treadmill exercise improved running performance
and fitness to the same extent as running training. Furthermore, this evidence
indicated that vertical treadmill can be used as a low-impact conditioning tool
without detriment to running performance or risk of traumatic or overuse injury. It
was suggested that the improvement in running performance on the vertical
treadmill was due to the vertical treadmill targeting and therefore conditioning of
the hip flexor muscles, hamstrings and gastrocnemius. Hip flexor, hamstring and
gastrocnemius condition have been implemented in the acceleration and
maximum velocity running performance, respectively.
Implications of the research
The research supports the anecdotal evidence and suggests that the vertical
treadmill would be a useful addition to an individual’s training programme without
the risk of overuse or traumatic injuries. More specifically, the vertical treadmill can
be used to improve aerobic and anaerobic running performance, despite being a
different exercise mode and therefore it could be considered a cross-training tool
for an athlete or coach. The vertical treadmill was modified on the basis of this
research to include additional resistance straps that originate from above and
below the user and attach to above the knee. The attachment of the resistance
bands to above the knee resolved the issue of vastii inactivity and so the vertical
treadmill offers a whole lower limb exercise. The latest model also allows an
increase in the resistance offered to the user, thus providing a method of
progression and overload. The tension of the recoil bands to allow full extension of
the hips and reduction of effort to stabilise the lumbar spine should be
individualised but could probably be achieved through three settings.
This research also provides the basis for training and rehabilitation
programmes in non-athletic populations. A key benefit of the vertical running
machine is the way in which it exercises the lower limbs similar to that of over
ground ambulation but significantly reduces impact loading of the lower
extremities. The vertical treadmill allows simultaneous exercise of the lower limbs
and development of core stability of the trunk, thus an individual’s fitness can be
improved or at a minimum it can be maintained on the vertical treadmill. Another
key concept of the vertical treadmill is that the lower limbs of the user are free to
undertake exercise within the range of motion that the injury or condition will allow,
unlike cycle ergometers and recumbent steppers where the range of motion is
defined by the pedal and crank arm. Also the vertical treadmill allows a wider
range of movement than the recumbent cycle ergometers and recumbent steppers
thus as an injury improves the range of motion can be increased to similar ranges
of motion used in over ground ambulation. Under the supervision of physiotherapy
professional the vertical treadmill could be used to rehabilitate those in which
impact loading is undesirable such as:
1. Amputees (both limbs of the transtibial amputees, and the intact limb of full
lower limb amputation) to strengthen the hip musculature recommended for
gait rehabilitation (Vanicek et al., 2009).
2. Trauma injuries such as sprains and over use injuries where impact loading
of injured tissues is undesirable, however the loss of physical fitness during
the injury rehabilitation process is equally undesirable.
3. Osteoporosis where impact loading of weakened bone and soft tissue is
undesirable, but the individual can exercise and maintain or even improve
fitness.
This research provides the basis for future research in conditioning and
rehabilitation of many injuries and conditions. The potential use of the vertical
treadmill for those conditions/injuires provided above will require trials by
rehabilitation professionals to evaluate the effectiveness of the vertical treadmill,
however it is important to note that the vertical is a safe exercise mode and there
has not been a single incident of injury or injury exacerbation during its use at
several professional sports clubs and clinical/rehabilitation environments

 

All done with one Strap per leg, also they dont mention recovery time is almost halved. dipstick .

 

Yeeeeaahhhhhhh, SCIENCE BISH!

 

Sorry, but this sounds like BS.

 

Why you bein a lil jealous *****?

Just accept the fact that you're not innovative.

You're a rub menthol on an athletes dlck dude.

That's what you do. You rub menthol on real athletes.

 

Jealous of...?

Huh?

More homo***ual thoughts...? :?

 

True Virus, the lady is the wife of the Head lecturer at the Uni, just won the league this year, the Boys times can be verified, and how He did it.

 

Plus I have had better results than those, Lots. Otherwise I wouldnt have gone for testing.

 

It's really sad the way some of the forum is reacting to your invention, scrap.

It's not like any of them are your competitors.

They don't even know you in real life, and as far as I know, both dealt with and virus don't even reside in the UK.

 

I agree. When somebody claims they took 14 seconds off an elite 800m runners time and 7 minutes off an elite triathlon runner's time without posting evidence, what right do we have to be skeptical, we should just accept as gospel. atsch Poor Scrap getting picked on.

Shows how little you know.

More trollin' fails.

 

So in conclusion it might be a good rehab tool that is comparable to running? How groundbreaking.... I also find it very hard to believe that somebody at the PhD level in a science related field would write like that, that was really poorly written and not written in a scientific style at all. Add in the hyperbole and a lack of any statistics... You sir are 100% full of ****. There are plenty of other things about it that I can point out that indicate there's nothing scientific about it, but I shouldn't waste any more time, anybody who is familiar with journal articles can see very clearly what it really is...

 

Ah.. You should probably learn what science is. You've gotta love something that isn't peer reviewed and has no statistics to back anything up other than a percentage (with no comparison to the control/other training group - a big no no and a clear sign that an idiot has put this together) and a load of hyperbole. It sounds like the guy who typed up that tripe on the website, it sounds scientific to the lay person but to somebody actually involved with scientific research and the topic being talked about it sounds like an infomercial designed to leech money out of boneheads who don't know any better.

 

I have no problem with his invention, I hope it proves to be a useful rehab tool. My objection is to his claims that it can do anything for an athlete. Even in the hyperbole piece he posted the conclusion is that it can improve fitness like running can but with less impact (not necessarily a good thing at all). Big deal.
