Effects of Fasting-Mimicking Diet on Central and Peripheral Components of Fatigue, Muscular Resistance (FMD_Exercise)
July 14, 2020 updated by: Matteo Bertucco, Universita di Verona
Effects of Fasting-mimicking Diet on Central and Peripheral Components of Fatigue, Muscular Resistance
The aim of the study is to test a Fasting Mimicking Diet (FMD) for its efficacy on improving muscular resistance and endurance.
The investigators will perform a randomized clinical trial to test the efficacy of the FMD on improving muscular strength, muscular resistance and endurance in physically active young adults (18-40 years of age).
The study will include two arms: Placebo (Placebo diet) and FMD (3 cycles of 5-day fasting-mimicking diet within two months).
Study endpoints will include muscular strength evaluation of lower limbs, cardio-pulmonary responses, neuromuscular function and muscle architecture.
Subjects will be evaluated 4 times within 3 months: at baseline (T1), after the 1st cycle of diet (T2), 7 to 15 days after the 3rd cycle of diet maintaining baseline intensity (T3) and with re-assessment of Peak Power Output (T4).

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Difference in time to exhaustion (TTE)
Time Frame: baseline (T1); day 5 (1°diet cycle - T1), after 2 months (T3 and T4)
|
Difference between time points in time duration [s] of the exercise at a given power output (85%) and cadence (60 RPM), before the given work rate could not be sustained.
|
baseline (T1); day 5 (1°diet cycle - T1), after 2 months (T3 and T4)
|
Change in maximal voluntary contraction (MVC)
Time Frame: baseline (T1); day 5 (1°diet cycle - T1), after 2 months (T3 and T4)
|
Variation between time points in maximal force voluntarily produced by the knee extensor muscles pre- and immediately post exercise, considering for lever length [N*m].
|
baseline (T1); day 5 (1°diet cycle - T1), after 2 months (T3 and T4)
|
Change in voluntary (muscle) activation (VA)
Time Frame: baseline (T1); day 5 (1°diet cycle - T1), after 2 months (T3 and T4)
|
Change between time points in the percentage of muscle activated by volition.
[%] To quantify voluntary activation, the amplitude of the superimposed twitch is expressed as a fraction of the twitch evoked by the same stimulus in the relaxed muscle.
|
baseline (T1); day 5 (1°diet cycle - T1), after 2 months (T3 and T4)
|
Change in resting twitch force (RT)
Time Frame: baseline (T1); day 5 (1°diet cycle - T1), after 2 months (T3 and T4)
|
Force elicited at rest by electrical stimulation of the femoral nerve, considering for lever length [N*m].
|
baseline (T1); day 5 (1°diet cycle - T1), after 2 months (T3 and T4)
|
Change in oxygen consumption (VO2)
Time Frame: baseline (T1); day 5 (1°diet cycle - T1), after 2 months (T3 and T4)
|
Variations of mean oxygen consumption at rest and at each minute while exercising (performance test).
|
baseline (T1); day 5 (1°diet cycle - T1), after 2 months (T3 and T4)
|
Change in peak (task-specific) oxygen consumption (VO2)
Time Frame: baseline (T1) and after 2 months (T4).
|
Peak oxygen consumption during the incremental test (maximal value during a 30" time-window).
|
baseline (T1) and after 2 months (T4).
|
Change in femoral (artery) blood flow (FBF)
Time Frame: at rest and during the performance test. Differences between each time point will be assessed: baseline (T1); day 5 (1°diet cycle - T1), after 2 months (T3 and T4)
|
Measurements of common femoral arterial blood velocity (Vmean) and vessel diameter will be performed using ultrasound Doppler, distal to the inguinal ligament and proximal to the bifurcation of the deep and superficial femoral arteries.
(FBF = Vmean p (vessel diameter/2)^2 * 60)
|
at rest and during the performance test. Differences between each time point will be assessed: baseline (T1); day 5 (1°diet cycle - T1), after 2 months (T3 and T4)
|

Time Frame: during the performance test at each time point: baseline (T1); day 5 (1°diet cycle - T1), after 2 months (T3 and T4)
|
EMG signal from the vastus lateralis (VL) muscle was recorded throughout exercise to estimate the output of spinal motoneurons and the development of peripheral fatigue.
|
