Effect of a Novel Blend of Plant Protein and Additional Ingredients on Resistance Training Adaptations
View on ClinicalTrials.gov
Updated Dec 15, 2025
Brief Summary
This study seeks to compare the observed changes in resistance training adaptations (strength, performance, body composition, recovery, and lactate responses) after supplementation of isocaloric and isonitrogenous amounts of a novel plant protein formulation against changes observed in a pea/rice plant protein blend, whey protein, and a carbohydrate placebo in healthy resistance-trained men and women between the ages of 18-39.

Primary Outcomes
Measure:
Change in 4-Compartment Lean Mass
TimeFrame:
Week 0, Week 4, and Week 8
Description:
Lean mass will be assessed using a 4-compartment model, which includes measurements of body density, total body water, and bone mineral content.
Measure:
Change in Perceptual Indicators of Training State
TimeFrame:
Week 0, Week 4, and Week 8
Description:
Participants will rate their readiness to train, soreness, recovery, energy, and sleep quality using 100-mm visual analog scales. Each scale is anchored with contextually appropriate statements such as "Lowest Possible" and "Highest Possible."
Measure:
Change in Profile of Mood States (POMS) Score
TimeFrame:
Week 0, Week 4, and Week 8
Description:
Mood state will be assessed using the Profile of Mood States (POMS) questionnaire, a validated tool for measuring transient affective states. The POMS consists of six subscales (Tension-Anxiety, Depression-Dejection, Anger-Hostility, Vigor-Activity, Fatigue-Inertia, and Confusion-Bewilderment), with a Total Mood Disturbance (TMD) score calculated by summing negative subscale scores and subtracting the Vigor score. Higher TMD scores indicate greater mood disturbance, while lower scores indicate improved mood state.
Measure:
Change in Pressure to Pain Threshold
TimeFrame:
Week 0, Week 4, and Week 8
Description:
Pressure pain threshold will be assessed using a digital algometer to determine the minimum pressure required to elicit pain. Higher scores indicate higher tolerance to pain.
Measure:
Change in Handgrip Strength
TimeFrame:
Week 0, Week 4, and Week 8
Description:
Maximal handgrip strength will be assessed using a calibrated hand dynamometer. Higher values indicate greater strength.
Measure:
Change in Isometric Mid-Thigh Pull Force
TimeFrame:
Week 0, Week 4, and Week 8
Description:
Maximal force output will be assessed using an isometric mid-thigh pull on a force plate, measured in Newtons. Higher scores equal greater force production
Measure:
Change in Hex Bar Deadlift One-Repetition Maximum (1RM)
TimeFrame:
Week 0, Week 4, and Week 8
Description:
Maximal hex bar deadlift strength will be assessed using a standardized one-repetition maximum (1RM) test.
Measure:
Change in Bench Press One-Repetition Maximum (1RM
TimeFrame:
Week 0, Week 4, and Week 8
Description:
Maximal upper-body strength will be assessed using a standardized one-repetition maximum (1RM) bench press test.
Measure:
Change in Isokinetic Peak Knee Extension Torque
TimeFrame:
Week 0, Week 4, and Week 8
Description:
Peak torque of the quadriceps will be assessed using an isokinetic dynamometer. Higher values indicate greater knee extensor strength.
Measure:
Performance in 5 Sets of Hex Bar Deadlift Protocol
TimeFrame:
Week 0, Week 4, and Week 8
Description:
Strength endurance will be assessed using a hex bar deadlift protocol consisting of 3 sets of 10 repetitions at 70% 1RM and 2 sets to failure at 80% 1RM. Repetition count and total volume lifted will be recorded.
