Recently I sent to this list the message shown at the bottom of this message. It
elicited two replies.

First Reply:

Relationship between walking speed (m/sec) and energy expenditure (kj/kg/min)
may not be linear even at a very narrow range, between 0.28 - 1.26 m/sec (Ghosh
et al, 1980; Ghosh et al, 1982). Within a very wide range, the relationship is
also not linear (Cotes & Meade, 1960; Durnin & Passmore, 1967; Margaria, 1968).

Economic walking or optimal walking speed can be calculated as energy cost per
kg per unit distance travelled (j/kg/m). When it is plotted against speed, the
relationship became curvilinear and at a certain speed, the energy cost (E) per
unit distance travelled became lowest, below and above this speed, the E was
found to be higher (Ghosh et al, 1980; 1982). I think if this approach is
applied in case of walkers, you may find a similar relationship and you may get
an "optimum" walking speed where the energy cost per unit distance travelled is
minimum. This optimum speed can be used for monitoring training schedule. Is
this optimum speed trainable?

Second Reply:

I have just had to teach this very topic, as far as i
can tell all your assumptions are correct. The question of
the competitive race walkers is more complex - in my opinion
their technique is actually an alternative gait to walking
(as you or i do) and running. Some basic facts and a good
source of refs for this topic is actually available in
McCardle et al's text book.  Although a typical undergrad
text book it seems the authors possess an interest in this
topic, to expand on your question the attached graph might
help - taken from MCC.

Gait transition cost in humans.

Usherwood JR, Bertram JE.

Florida State University, Tallahassee, FL 32306, USA.

The energetics of locomotion depend largely on speed, gait and body size. Gait
selection for a given speed appears partly, but perhaps not wholly, related to
metabolic cost. One cost normally omitted from considerations of locomotion
efficiency is the metabolic cost of the transition between gaits. We present the
first direct assessment of the metabolic cost for the walk-run/run-walk
transition in humans. The average increase in metabolic cost for a step
involving a transition is 1.75 times that of a mean non-transition step at a
speed where metabolic power requirements are identical for walking and running.
Despite this substantial increase in cost for the transition step, the metabolic
cost of gait transition is unlikely to have a strong bearing on the process of
gait selection as the cost of using a metabolically inappropriate gait, even for
only a few steps, will dominate.

Does training have consequences for the walk-run transition speed?

A number of authors when studying the walk-run transition phenomenon focused
either on the mechanical or energy expenditure whilst only a few used both
parameters concurrently. Moreover the literature demonstrates that the
contribution of these variables changes along with the level and method of
training. Consequently the purpose of this study is to find, by analyzing
concurrently these two variables, if the walk-run transition speed is linked to
the type of training. To this end we calculated two theoretical transition
speeds: one based on the metabolic energy expenditure St(1) and the second one
based on the internal work St(2). Subjects were divided into three groups
(untrained, sprint and endurance-trained men) who were required to walk and run
on a treadmill at increasing speeds. Firstly we show that the relationship
between St(1) and St(2) differs depending on the groups. Sprinters have a
significantly lower St(2) than St(1) whereas the opposite is found for
untrained!
  subjects. We also show that the transition speed is linked to the subject's
type of training. To conclude it seems that acquiring running techniques through
specific training has consequences for the walk-run transition phenomenon.

Are transitions in human gait determined by mechanical, kinetic or energetic
factors?

Raynor AJ, Yi CJ, Abernethy B, Jong QJ.

School of Health Sciences, University of South Australia, Holbrooks Road,
Underdale, SA 5032, Australia. annette.raynor@...

It is currently unclear whether it is the need to maintain metabolic efficiency,
the need to keep skeletal loading below critical force levels, or simple
mechanical factors that drive the walk-to-run (W-R) and run-to-walk (R-W)
transitions in human gait. Eighteen adults (9 males and 9 females) locomoted on
an instrumented treadmill using their preferred gait. Each completed 2 ascending
(W-R) and 2 descending (R-W) series of trials under three levels of loading (0%,
15% and 30% body weight). For each trial, participants locomoted for 60 s at
each of 9 different speeds--4 speeds both above and below their preferred
transition speed (PTS) plus their PTS. Evidence was sought for critical levels
of key kinetic (maximum vertical force, impulse, first peak force, time to first
peak force and maximum loading rate), energetic (oxygen consumption, transport
cost) and mechanical variables (limb lengths, strength) predictive of the gait
transition. Analyses suggested the kinetic variabl!
es of time to first peak force and loading rate as the most likely determinants
of the W-R and R-W transitions.

Comparison between preferred and energetically optimal transition speeds in
adolescents.

Carolina at Wilmington, 601 South College Road, Wilmington, NC 28403, USA.

The primary focus of this investigation was to determine whether differences
exist between the preferred transition speed (PTS) and the energetically optimal
transition speed (EOTS) in a group of adolescents. Ten 11-, ten 13-, and ten
15-year-olds completed four testing sessions. Following 30 min of accommodation
to treadmill walking and running (session 1), the PTS between walking and
running was identified in session 2. In session 3, subjects walked on a level
treadmill at 70%, 80%, 90%, 100%, and 110% of respective PTS, while in session
4, children ran on a level treadmill at 90%, 100%, 110%, 120%, and 130% of
respective PTS. During the last 2 min of each 5-min walking and running bout,
expired gas samples were collected in a meteorological balloon and analyzed to
calculate VO2 and the EOTS between walking and running. Data analyses revealed
that mean EOTS was significantly higher than mean PTS within each age group.
Furthermore, when subjects changed gaits, the aerobic d!
emand needed to run at the PTS was not lower than the VO2 measured while walking
at the PTS. A moderately strong positive coefficient (r = 0.71) between leg
length and PTS was also observed. Taken together, these data suggest factors
other than govern the walk-run transition in adolescent boys and girls.

Energetics and optimization of human walking and running: the 2000 Raymond Pearl
memorial lecture.

McNeill Alexander R.

School of Biology, University of Leeds, Leeds LS2 9JT, United Kingdom.
r.m.alexander@...

Humans seem to adjust their walking and running gaits to minimise the metabolic
energy cost of locomotion. The walking speed that we tend to prefer is the one
that minimises energy cost per unit distance, though faster speeds might seem
preferable when time is valuable. At speeds up to 2 m/s, walking requires less
energy than running, and we walk. At higher speeds, running is more economical,
and we run. At each speed we use the stride length that minimises energy costs.
A computer model that predicts metabolic rates for all conceivable gaits of a
simple biped helps to understand these and other features of human gait. The
energy cost of walking is increased on uphill slopes and also on soft ground.
Consequently, zigzag paths should be preferred to straight ones, up hills of
more than a critical gradient. Also, it may be more economical to divert a path
around a hill than to travel along a straight line. Simple theories of optimum
diversions are presented, both for hilly gro!
und and for ground interrupted by marshy patches, on which costs of walking are
increased. Energy costs are also increased by heavy loads, though it seems
possible in some circumstances to carry moderate loads without measurable extra
cost.

To: 'Sportscience email list'
Subject: SEC: U Energy costs of running versus walking

A question has arisen on a professional nutrition email discussion list about
the relative efficiency of energy use during running compared to walking.

By way of background, the data in Ainsworth et al (1999) and Ainsworth et al
(2000) indicate that:

Walking at 2 mph (3.2 kph) has a MET equivalent of 2.5.
For 3 mph (4.8 kph) , the MET equivalent is 3.5.
For 3.5 mph (5.6 kph), the MET equivalent is 4.0.
For 5 mph (8 kph), the MET equivalent is 8.0.

If you graph these, the curve for rate of energy expenditure against speed is
approximately linear at least up to 5.6 kph. Somewhere between 5.6 kph and 8 kph
there appears to be an inflection point and energy expenditure then increases at
a greater rate than speed.

Also from the references cited, walking at 8 kph involves the same energy cost
as running at 8 kph (8 METs in each case).

Is it reasonable to assume that below ~8 kph walking is more energy efficient
than running for most people, while above ~8 kph running is generally the more
economical gait?

If so, does this also apply to competitive walkers, or does their technique mean
that the 'crossover point' (at which running economy is greater than walking
economy) occurs at a higher speed?

I am a runner in San Francisco, CA that was frustrated by trying to
determine exact route distances.  I found driving them to be tedious,
time consuming, and less than accurate, especially when I wanted to
run on trails, through parks, and down one-way streets where cars
cannot go.

So, I got together with another runner-friend of mine and created a
FREE online application called Route Ruler, which allows athletes to
draw their own routes on downloaded maps and gives them exact
distances. As far as we know this is the only free service of its
kind, and it eliminates the need for buying costly GPS gadgets.

We are still fine-tuning some of the features and look of the site,
but we do have a website up at www.routeruler.com  , and want you to
take a look at it. We feel it could turn out to be a great training
tool for some of your subscribers.

Since you are the experts, we wanted to see if you would send us any
comments you might have. If you like it, please feel free to tell your
subscribers, we feel it could prove a useful training tool for them.
Also please feel free to post a link to our site.  We will be
constantly improving the look and usability of Route Ruler through the
coming months.

I hope you like it, and I look forward to any comments you may send.

As a volunteer I coordinate a training group that is focused on preparing
for long endurance events (7 to 14 hours).

One of things we teach our members is how to fuel themselves for long
continuous efforts.  We have suggested the use of several products because
they allow for a relatively easy intake of calories amounting to about 250
to 300 calories per hour at a reasonable pace.

It was recently brought to my attention, however, that some of these
products also contain Chromium Nicotinate.  Normal usage of the product
would result in about 100 micrograms per hour.  During a 12 hour event,
that would amount to 1200 micrograms.  In scanning the literature we have
not found studies that have looked closely at this level of intake but
there are some reports of toxicity when high amounts of Chromium Picolinate
are taken over a period of time.

When asked, the producer of the products stated that because it has been
shown that chromium is lost during exercise, taking in up to 6000
micrograms should be safe.

I'm aware that recent studies have failed to show that there are clear
benefits of chromium supplementation, however, we do find that these
products are very convenient for their overall formulation of
nutrients.  My only question relates to whether or not the level of
chromium (1200 mcgs/event) is safe.

Here are the conditions stated plainly:

    100 micrograms of Chromium Nicotinate per hour taken during exercise
    Exercise lasting from 4 to 14 hours (including event duration)
    Intake of chromium amounting to 400 to 1400 micrograms per exercise
    Participants exercise 4-6 times a week, during training
    Training durations are limited to 6-8 hours maximum
    Event duration ranges from 7 to 14 hours

In a normal training week participants are ingesting a maximum of 2000 mcg
of Chromium Nicotinate.

I think that event day is of greatest concern because the average
participant will take in about 1,000 mcgs and several will take in 1,200 to
1,400 mcgs during the event.

Please, if you can, defer comment on the efficacy of chromium
supplementation and please let me know what you know about the safety of
taking 1,400 mcgs during exercise.

Sincerely,

Joe

I'm an exercise physiologist beginning to a line of research with
a colleague who is a physical therapist.  We are currently exploring
options for obtaining an 8 channel EMG machine, preferably with
telemetry as an option.  We have looked at all the common companies-
Biopac, Konisberg, Delsys, etc, and at this point the prices are
beyond our budget.  We would appreciate any information on other
systems (cost below about $9000 US) that are new or used.  In addition
if anyone is aware of companies that lease we would appreciate that
information too.  Thanks

I've been trying to help one of my students modify a Monark cycle
ergometer for a Wingate test using the instructions and equipment
described by Biopac at http://biopac.com/bsl_frsupport.htm (Pro Lesson
H05).  They describe a "Silicone pin photodiode (designed for detection
of infrared radiation" and state further that "The photodiode (TOX
9100) was obtained from Texas Optoelectronics, Inc. in Garland, Texas."

I've been unable to locate the TOX 9100 and wonder if anyone has any
suggestions about "silicone pin photodiodes" (I'm not an "electrical"
kind of guy, so this stuff is as clear as mud.)  I visited a local
electronics shop (Norvac) and the guy I talked with wasn't much help,
largely because I couldn't tell him the exact specifications for such
equipment.

Anyone have any useful input on this?  Thanks.

Mike

Hey everyone, I have a question about the Monark 827 bike "ergometer."
I found out that this one isn't actually an ergometer. The company I
just started working at bought it without consulting anyone, and we
have people who we need to schedule for submax aerobic capacity tests.
However on the 827, you can't set the resistance (in Newtons), and
therefore can't run any of the ACSM submax bike tests.

There are letters (A through F maybe) that look like they adjust
resistance, but no numbers to give us more exact power output levels.
Did anyone ever use this or know how much resistance those letters
offer?
Thanks!

We plan to establish a physiological model of interval training, which
requires exposing a large number of athletes to a wide variety of
interval training sessions. We are familiar with G. Purdy's
computerized running training tables and we have already proposed an
empirical and graphic model to help coaches and serious athletes: 1)
assess how each element of such training sessions can vary at a given
level of difficulty, 2) plan workouts and 3) develop long term training
plans. The cycling applications of the proposed interval training model
is presented in the Canadian Cycling Association web site:
http://www.canadian-cycling.com/English/news/documents/interval_training_model_a\
nd_computrainer.pdf

Does anyone know of an already existing physiological model of interval
training?

Dear Guy,

I’m not sure this will help you, but haven’t you heard about the model
developed by Morton RH, Billat LV

The critical power model for intermittent exercise.
Eur J Appl Physiol. 2004 Mar;91(2-3):303-7. Epub 2003 Oct 28

Would you find any application with your studies?
