Umberger2010MuscleMetabolicsProbe Interface

These accessor methods are to be used when setting up a new muscle metabolic analysis from the API.

The basic operation is as follows:

model.addProbe(myProbe);
myProbe->addMuscle("muscleName1", ... );
myProbe->addMuscle("muscleName2", ... );
myProbe->addMuscle("muscleName3", ... );
myProbe->useProvidedMass("muscleName1", 1.2); // muscle1 mass = 1.2 kg
myProbe->useCalculatedMass("muscleName2"); // muscle2 mass is based on muscle properties (below)
myProbe->setDensity("muscleName2", 1100.0); // muscle2 density is 1100 kg/m^3
myProbe->setSpecificTension("muscleName2", 0.26e6); // muscle2 specific tension is 0.26e6 Pa
myProbe->removeMuscle("muscleName3");
myProbe->setOperation("integrate") // See OpenSim::Probe for other operations
Note
It is important to first add the metabolic probe to the model before calling any other methods that may modify its properties. This is because some methods (e.g. addMuscle() or useCalculatedMass) may require information about the muscles to successfully execute, and this information can only be obtained if the metabolic probe is already 'connected' to the model.

Detailed Description

Umberger2010MuscleMetabolicsProbe is a Probe ModelComponent for computing the net metabolic energy rate of a set of Muscles in the model during a simulation.

Umberger2010MuscleMetabolicsProbe Theory

The discussion here is based on the following papers:

Uchida, T. K., Hicks, J. L., Dembia, C. L., Delp, S. L. (2016). Stretching your energetic budget: how tendon compliance affects the metabolic cost of running. PLOS ONE 11(3), e0150378.

Umberger, B. R. (2010). Stance and swing phase costs in human walking. J R Soc Interface 7, 1329-40.

Umberger, B. R., Gerritsen, K. G. and Martin, P. E. (2003). A model of human muscle energy expenditure. Comput Methods Biomech Biomed Engin 6, 99-111.

Note that the equations below that describe the particular implementation of Umberger2010MuscleMetabolicsProbe may slightly differ from the equations described in the representative publications above. Note also that we define positive muscle velocity to indicate lengthening (eccentric contraction) and negative muscle velocity to indicate shortening (concentric contraction).

Muscle metabolic power (or rate of metabolic energy consumption) is equal to the rate at which heat is liberated plus the rate at which work is done:
Edot = Bdot + sumOfAllMuscles(Adot + Mdot + Sdot + Wdot).

  • Bdot is the basal heat rate (W).
  • Adot is the activation heat rate (W).
  • Mdot is the maintenance heat rate (W).
  • Sdot is the shortening heat rate (W).
  • Wdot is the mechanical work rate (W).

This probe also uses muscle parameters stored in the MetabolicMuscle object for each muscle. The full set of all MetabolicMuscles (MetabolicMuscleSet) is a property of this probe:

  • m = The mass of the muscle (kg).
  • r = Ratio of slow-twitch fibers in the muscle (between 0 and 1).

The recruitment model described by Bhargava et al. (2004) is used to set the slow-twitch fiber ratio used in the calculations below. The ratio specified by the user indicates the composition of the muscle; this value is used only at full excitation (i.e., when all fibers are recruited). As excitation decreases from 1 to 0, the proportion of recruited fibers that are slow-twitch fibers increases from r to 1. See Bhargava, L.J., Pandy, M.G., Anderson, F.C. (2004) A phenomenological model for estimating metabolic energy consumption in muscle contraction. J Biomech 37:81-88 and Uchida et al. (2016). To assume a constant ratio of slow- and fast-twitch fiber recruitment, set the 'use_Bhargava_recruitment_model' property to false.

BASAL HEAT RATE (W)

If basal_rate_on is set to true, then Bdot is calculated as follows:
Bdot = basal_coefficient * (m_body^basal_exponent)

  • m_body = mass of the entire model
  • basal_coefficient and basal_exponent are defined by their respective properties.
    Note that this quantity is muscle independent. Rather it is calculated on a whole body level.

ACTIVATION & MAINTENANCE HEAT RATE (W)

If activation_maintenance_rate_on is set to true, then Adot+Mdot is calculated as follows:
Adot+Mdot = [128*(1-r) + 25] * A^0.6 * S , l_CE <= l_CE_opt
Adot+Mdot = (0.4*[128*(1-r) + 25] + 0.6*[128*(1-r) + 25]*F_CE_iso) * A^0.6 * S , l_CE > l_CE_opt

  • A = u , u > a
  • A = (u+a)/2 , u <= a
  • m = The mass of the muscle (kg).
  • l_CE = muscle fiber length at the current time.
  • l_CE_opt = optimal fiber length of the muscle.
  • F_CE_iso = normalized contractile element force-length curve.
  • u = muscle excitation at the current time.
  • a = muscle activation at the current time.
  • S = aerobic/anaerobic scaling factor, defined by the 'aerobic_factor' property (i.e. usually 1.0 for primarily anaerobic activities, 1.5 for primarily aerobic activities).

SHORTENING HEAT RATE (W)

If shortening_rate_on is set to true, then Sdot is calculated as follows:
Sdot = m * (-[(alphaS_slow * v_CE_norm * r) + (alphaS_fast * v_CE_norm * (1-r))] * A^2 * S) , l_CE <= l_CE_opt & v_CE >= 0 (concentric / isometric contraction)
Sdot = m * (-[(alphaS_slow * v_CE_norm * r) + (alphaS_fast * v_CE_norm * (1-r))] * A^2 * S * F_iso) , l_CE > l_CE_opt & v_CE >= 0 (concentric / isometric contraction)
Sdot = m * (alphaL * v_CE_norm * A * S) , l_CE <= l_CE_opt & v_CE < 0 (eccentric contraction)
Sdot = m * (alphaL * v_CE_norm * A * S * F_CE_iso) , l_CE > l_CE_opt & v_CE < 0 (eccentric contraction)

  • A = u , u > a
  • A = (u+a)/2 , u <= a
  • alphaS_fast = 153 / v_CE_max
  • alphaS_slow = 100 / (v_CE_max / 2.5)
  • alphaL = 4.0 * alphaS_slow
  • m = The mass of the muscle (kg).
  • l_CE = muscle fiber length at the current time.
  • l_CE_opt = optimal fiber length of the muscle.
  • F_CE_iso = force that would be developed by the contractile element of muscle under isometric conditions with the current activation and fiber length.
  • v_CE = muscle fiber velocity at the current time.
  • v_CE_max = maximum shortening velocity of the muscle.
  • v_CE_norm = normalized muscle fiber velocity (defined for this model as v_CE/l_CE_opt). Note that this is a different metric to the typical normalized_muscle_fiber_velocity of v_CE/v_CE_max.
  • S = aerobic/anaerobic scaling factor, defined by the 'aerobic_factor' property (i.e. usually 1.0 for primarily anaerobic activities, 1.5 for primarily aerobic activities).

MECHANICAL WORK RATE (W)

If mechanical_work_rate_on is set to true, then Wdot is calculated as follows:
Wdot = -(F_CE * v_CE)

  • v_CE = muscle fiber velocity at the current time.
  • F_CE = force developed by the contractile element of muscle at the current time.
    If we draw a control volume around the fiber, the first law of thermodynamics suggests that negative mechanical work should be included in Wdot. As such, we revert back to the model described in Umberger et al. (2003) by default. To exclude negative mechanical work from Wdot and use a coefficient of 0.3 (rather than 4.0) to calculate alpha_L, set the 'include_negative_mechanical_work' property to false.

During eccentric contraction, the magnitude of the (negative) mechanical work rate can exceed that of the total (positive) heat rate, resulting in a flow of energy into the fiber. Experiments indicate that the chemical processes involved in fiber contraction cannot be reversed, and most of the energy that is absorbed during eccentric contraction (in increased cross-bridge potentials, for example) is eventually converted into heat. Thus, we increase Sdot (if necessary) to ensure Edot > 0 for each muscle. See Constable, J.K., Barclay, C.J., Gibbs, C.L. (1997) Energetics of lengthening in mouse and toad skeletal muscles. J Physiol 505:205-215 and Uchida et al. (2016). To allow muscles to have negative total power, set the 'forbid_negative_total_power' property to false.

Note that if enforce_minimum_heat_rate_per_muscle == true AND activation_maintenance_rate_on == shortening_rate_on == true, then the total heat rate (AMdot + Sdot) will be capped to a minimum value of 1.0 W/kg (Umberger(2003), page 104).

Umberger2010MuscleMetabolicsProbe_MetabolicMuscleParameter

Umberger2010MuscleMetabolicsProbe_MetabolicMuscleParameter is an Object class that holds the metabolic parameters required to calculate metabolic power for a single muscle.

Umberger2010MuscleMetabolicsProbe_MetabolicMuscleParameter Properties

REQUIRED PROPERTIES

  • specific_tension = The specific tension of the muscle (Pascals (N/m^2)).
  • density = The density of the muscle (kg/m^3).
  • ratio_slow_twitch_fibers = Ratio of slow twitch fibers in the muscle (must be between 0 and 1).

OPTIONAL PROPERTIES

  • use_provided_muscle_mass = An optional flag that allows the user to explicitly specify a muscle mass. If set to true, the 'provided_muscle_mass' property must be specified. The default setting is false, in which case, the muscle mass is calculated from the following formula: m = (Fmax/specific_tension)*density*Lm_opt, where specific_tension and density are properties defined above (note that their default values are set based on mammalian muscle, 0.25e6 N/m^2 and 1059.7 kg/m^3, respectively); Fmax and Lm_opt are the maximum isometric force and optimal fiber length, respectively, of the muscle.
  • provided_muscle_mass = The user specified muscle mass (kg).
