Whole-Body Strength Training Using a Huber Motion Lab in Coronary Heart
Disease Patients: Safety, Tolerance, Fuel Selection, and Energy
Expenditure Aspects and Optimization

Guiraud T, Labrune´e M, Pillard F, Granger R, Bousquet M, Richard L, Boned A,

Objective:
The aim of this study was to investigate safety, tolerance, relative
exercise intensity, and muscle substrate oxidation during sessions performed on a
Huber Motion Lab in coronary heart disease patients.
Design: After an assessment of V˙ O2
peak, 20 coronary heart disease patients
participated in two different exercises performed in random order at 40% and
70% (W40 and W70) of the maximal isometric voluntary contraction.

Results:
No significant arrhythmia or abnormal blood pressure responses
occurred during either session, and no muscle soreness was reported within 48
hrs posttest. The authors found a difference between W40 and W70 sessions for
mean (standard deviation) ventilation (25.1% [8%] and 32.1% [9%] of maximal
ventilation, respectively;
P
= 0.04) and a small difference for mean (standard
deviation) heart rate (73 [7] and 79 [8] beats/min, respectively;
P G
0.01). When
compared with the W40, the W70 was associated with higher active energy
expenditure (2.4 [0.6] and 3.1 [0.9] Kcal/min, respectively;
P G
0.0001) and a
similar mean (standard deviation) oxygen uptake (5.5 [1] and 6.6 [1] ml/min per
kilogram, respectively;
P
= 0.07). The qualitative percentages of carbohydrates
and lipids oxidized were 71% and 29%, respectively, at W40 and 91% and 9%,
respectively, at W70.
Conclusions:
Both protocols, which consisted of repeating 6-sec phases of
contractions with 10 secs of passive recovery on the Huber Motion Lab, seemed
to be well tolerated, safe, and feasible in this group of coronary heart disease patients.
