While intermittent hypoxic training (IHT) has been reported to evoke cellular responses via hypoxia inducible factors (HIFs) but without substantial performance benefits in endurance athletes, we hypothesized that repeated sprint training in hypoxia could enhance repeated sprint ability (RSA) performed in normoxia via improved glycolysis and O(2) utilization. 40 trained subjects completed 8 cycling repeated sprint sessions in hypoxia (RSH, 3000 m) or normoxia (RSN, 485 m). Before (Pre-) and after (Post-) training, muscular levels of selected mRNAs were analyzed from resting muscle biopsies and RSA tested until exhaustion (10-s sprint, work-to-rest ratio 1:2) with muscle perfusion assessed by near-infrared spectroscopy. From Pre- to Post-, the average power output of all sprints in RSA was increased (p<0.01) to the same extent (6% vs 7%, NS) in RSH and in RSN but the number of sprints to exhaustion was increased in RSH (9.4±4.8 vs. 13.0±6.2 sprints, p<0.01) but not in RSN (9.3±4.2 vs. 8.9±3.5). mRNA concentrations of HIF-1α (+55%), carbonic anhydrase III (+35%) and monocarboxylate transporter-4 (+20%) were augmented (p<0.05) whereas mitochondrial transcription factor A (-40%), peroxisome proliferator-activated receptor gamma coactivator 1α (-23%) and monocarboxylate transporter-1 (-36%) were decreased (p<0.01) in RSH only. Besides, the changes in total hemoglobin variations (Δ[tHb]) during sprints throughout RSA test increased to a greater extent (p<0.01) in RSH. Our findings show larger improvement in repeated sprint performance in RSH than in RSN with significant molecular adaptations and larger blood perfusion variations in active muscles.

Abstract
PURPOSE:

This study aimed to examine the reliability and validity of the steep ramp test (SRT), a feasible, maximal exercise test on a cycle ergometer that does not require the use of respiratory gas analysis, in healthy children and adolescents.
METHODS:

Seventy-five children were randomly divided in a reliability group (n = 37, 17 boys and 20 girls; mean ± SD age = 13.86 ± 3.22 yr), which performed two SRTs within 2 wk, and a validity group (n = 38, 17 boys and 21 girls; mean ± SD age = 13.85 ± 3.20 yr), which performed both an SRT and a regular cardiopulmonary exercise test (CPET) with respiratory gas analysis within 2 wk. Peak work rate (WRpeak) was the main outcome of the SRT. Peak oxygen uptake (VO2peak) was the main outcome of the CPET. Reliability was examined with the intraclass correlation coefficient and a Bland and Altman plot, whereas validity was assessed using Pearson correlation coefficients and stepwise linear regression analysis.
RESULTS:

Reliability statistics for the WRpeak values attained at the two SRTs showed an intraclass correlation coefficient of 0.986 (P < 0.001). The average difference between the two SRTs was -6.4 W, with limits of agreement between +24.5 and -37.5 W. A high correlation between WRpeak attained at the SRT and the V?O2peak achieved during the CPET was found (r = 0.958; P < 0.001). Stepwise linear regression analysis provided the following prediction equation: VO2peak (mL·min) = (8.262 WRpeak SRT) + 177.096 (R2 = 0.917, SEE = 237.4).
CONCLUSION:

The results suggest that the SRT is a reliable and valid exercise test in healthy children and adolescents, which can be used to predict VO2peak.

Abstract
Objectives: To determine content validity of the Muscle Power Sprint Test (MPST), and construct validity and reliability of the MPST, 105
Meter Sprint Test (105MST), slalom test, and One Stroke Push Test (1SPT) in wheelchair-using youth with spina bifida (SB).
Design: Clinimetric study.
Setting: Rehabilitation centers, SB outpatient services, and private practices.
Participants: A convenience sample of children and adolescents (NZ53; 32 boys, 21 girls; age range, 5e19y) with SB who use a manual
wheelchair. Participants were recruited through rehabilitation centers, SB outpatient services, pediatric physical therapists, and the BOSK
(Association of Physically Disabled Persons and their Parents).
Interventions: Not applicable.
Main Outcome Measures: Construct validity of the MPST was determined by comparing results with the arm-cranking Wingate Anaerobic Test
(WAnT) using paired t tests and Pearson correlation coefficients, while content validity was assessed using time-based criteria for anaerobic
testing. Construct validity of the 105MST, slalom test, and 1SPT was analyzed by hypothesis testing using Pearson correlation coefficients and
multiple regression. For reliability, intraclass correlation coefficients (ICCs) and smallest detectable changes (SDCs) were calculated.
Results: For the MPST, the mean SD exercise time of 4 sprints was 28.16.6 seconds. Correlations between the MPSTand arm-crankingWAnT
were high (r>.72, P<.01). Excellent correlations were found between the 105MSTand slalom test (rZ.93, P<.01), while correlations between the
105MSTor slalom test and MPSTand 1SPTwere moderate (rZ.56 to.70; rZ.56, P<.01). The variation of the 1SPTwas explained for 38% by
wheelchair mass (bZ.489) and total upper muscle strength (bZ.420). All ICCs were excellent (ICCs>.95), but the SDCs varied widely.
Conclusions: The MPST is a valid and reliable test in wheelchair-using youth with SB for measuring anaerobic performance. The 105MST and
slalom test are valid and reliable for measuring agility. For the 1SPT, both validity and reliability are questionable.

Support

Q - Is it possible to control the Lode ergometers and treadmills with external equipment

Yes, you can find interface sheets for most common devices on the website at the "service" tab of this website. If your device is not present you can ask us to support you. In most cases we can quickly provide you with a solution.

Q - Why should I upgrade from LEM 8 to LEM 9?

Version 9 of the LEM software added the following list of new features and improvements in comparison to version 8

Main adaptations and features
Software installation has made easy through a single installation CD, upgrades can be activated by just ordering the additional license that will be provided to you by E-mail.
Target Distance and Energy is implemented as a protocol stage. A target distance or energy level can be defined for each test subject to perform during the test.
Support for PWC (Physical Work Capacity) protocols. The Physical Work Capacity protocol can be used for different custom defined target heart rates. When the selected heart rate is reached the protocol will go to the recovery stage.
Heart rate controlled protocol stage for treadmills are possible now when the treadmill is equipped with the heart rate option
A new start tool for the Module Wingate plus is developed. It is possible now to define a pedal frequency (rpm) to start the wingate sprint test when this rpm is reached. When a test subject is speeding up during the count down phase this feature can be used.
In stead of programming body weight protocols for every separate body weight it is possible now to create body weight controlled bicycle protocol steps, as a percentage of the body weight. These protocols can be used for test subjects with a different body weight.
The new Protocol wizard will help to create protocols simply and quick. Normal Step, interval and bodyweight controlled (only bicycle) protocols can be created for the ergometers and treadmills
Protocols can be stored in folders, a menu structure for each purpose or group of test subjects can be created
The well known protocol developed by the World Health Organization is standard included in LEM as WHO protocol, 25 Watt/min
To adjust the workload or speed/slope manually during the exercise test it is possible now to enter the desired value in addition to up/down arrow buttons.
In the Test subject database a new field is created for the fat percentage. This data can be used by the LEM Astrand module in the Astrand statistics
The ergometer tree in the application is constructed directly from the license file
A new visualization is implemented: METS the metabolic equivalent for the resting metabolic rate
A demo mode can be found standard in the LEM database: a test from the database is used as data source for a new test. This enables LEM demonstrations without use of an ergometer.
In addition to the step time the new time to next stage counter is shown in the numeric bar.
The German translation of the LEM software is available now

Further smaller enhancements
In addition to the relative steps of the user defined protocols the Protocol Editor is enhanced: The user can now enter absolute load/speed/slope
When the SPO2 option is used for the heart rate results in LEM the Graphs of measurement series will be interrupted if SPO2 or heart rate data is missing. In earlier versions of LEM the graph show vertical lines each time the data was missing.
Thickness of lines in printed graphs has been increased.
The logical order of buttons in toolbar (next stage, previous stage, go to recovery, ...) has been improved.

Other changes
A pause of a test now pauses protocol execution while data acquisition continues.
Minimum duration of Wingate test reduced to 3 seconds. The original Wingate protocol is defining a sprint stage of 30 seconds. For research however it is necessary to be able to define very small sprint durations
Improved interface for editing remarks in analysis

Q - Why should I upgrade from LEM 7 to LEM 8?

Upgrading from Lode Ergometry manager 7 to 8 delivers you the following improvements

New Adaptations and Features
Support for SQL Server (express) 2005 for data storage. Storage in a local access file is still supported (and is the default).
Distance visualization for treadmills is implemented.

Further smaller enhancements
Software is now compatible with OS Microsoft Windows 7
Higher performance importing test. More tests can be imported in less time
The LEM software supports all Cycle ergometer that can be set to the Lode 38k4 RS232 protocol and Lode treadmill.
The ergometers are devided into two classes , Bicycle and treadmill ergometers

Other changes
Test-Files are stored in a database in the application data directory to reduce errors and make it possible to work with multiple users on the same database.
Format for exporting and back upping files has been changed to zipped XML files.

Q - Why should I upgrade from LEM 6 to LEM 7?

Upgrading from Lode Ergometry manager 6 to 7 delivers you the following added functionality

New Features
Added treadmill control to LEM. From this software version on it is possible to control the Lode treadmills with LEM.
The LEM Multi Bike control Module is now called Multi Control, Bicycle ergometers and treadmill ergometers can be used in the same environment at the same time. This is a good feature for a.o. rehabilitation.

Q - What are the differences between version 9.3 and 9.4 of LEM

Added:
- A new Questionnaire module is now available, a seperate licence is needed
- Syntax check and error message for Architect formula's is now available
- Warmup stage: works like step stage and can only be used as first stage in the protocol.

Adaptations:
- Protocol dialog has been converted to a model dialog, so it's clear to the user when the protocol is saved (ie. when the OK button in de model dialog is pressed)
- When a new stage is added to a protocol, the result will be visible immediatly. Instead of adding an invisible stage ('None' type), a stage of the same type of the selected stage will be added.
- Move login/logout functionality from Tools menu to menu bar itself
- Start Button changes into Pause/Resume button while a test is running, instead of Stop
button.
- Menu items whose functionality is available elsewhere have been removed.
- Order of (left) quick choice menu has been changed
- LEM Layout is automatically stored when the application is closed, and reloaded when it
is started again.

Improvements
- PFM test visualizations did not show the correct angle range when opened while test was already running. Usually the last 2 (or 10) complexes are shown, but this increased to the number of complexes depending on how long the test has been running at the moment the visualization was openened.
- Incorrect start time in PFM export (to xls/ascii) when data from first angle of complex was missing.

Q - What are the changes in LEM Version 9.4.5 compared to the previous version 9.4.4?

The permitted range of Astrand protocol parameters is extended
Color coded text showing success/failure of ergometer/pfm connection attempt makes more sense: Red: No connection, Green: connection OK
Increased update frequency of PFM graphs from 1Hz to 10Hz to improve readability
Changed unit of 'Total Work' in wingate statistics from J to KJ, Export still uses Joule, because changing the unit there may break automated processing of the excel file.

Q - Why should I upgrade from LEM V9 to LEM V10

LEM 10 has been redesigned from the ground up.
A complete redesign of the workflow makes your activities more efficient
Automatic detection of connected devices allows for easy connection and detection.

For Excalibur:
- visualisation of saddle and handlebar adjustment.

For PFM (Pedal Force Measurement):
- new visualisation of PFM data in a polar diagram (Force, Torque, Load) for single, combined and added sides.
- easy zoom in on Area's of Interest
- easy link to other data
- easy zeroing with feedback.

For Wingate
- OPTION TO COMPARE WINGATE RESULTS 6-8-9-20
- PP5

Q - Can I use a RS232 to USB converter to connect an ergometer?

Yes you can. Make sure the chipset used in the converter is from FTDI to have good data acquisition.
Not sure what this means? Contact us and we will help you to get the right converter.

Q - What should I check prior to upgrading to LEM10?

It is important to update the firmware of your existing ergometer to the latest version. This guarantees correct communication between the software and your product and the most optimal userexperience.

Also check if your Windows version is 7 or higher.
