Clinical Trial Summary

The objectives of this study are to:

1. Establish whether combined β-lactoglobulin supplementation and resistance training for 1 week prior to 5 days of limb immobilisation will attenuate the decrease in integrated free-living rates of MPS during short-term muscle disuse.

2. Establish whether combined β-lactoglobulin supplementation and resistance training for 1 week prior to limb immobilisation will attenuate the decrease in muscle mass and strength during short-term muscle disuse.

Description:

The objectives of this study are to:

1. Establish whether combined β-lactoglobulin supplementation and resistance training for 1 week prior to 5 days of limb immobilisation will attenuate the decrease in integrated free-living rates of MPS during short-term muscle disuse.

2. Establish whether combined β-lactoglobulin supplementation and resistance training for 1 week prior to limb immobilisation will attenuate the decrease in muscle mass and strength during short-term muscle disuse.

Hypotheses

1. Combining β-lactoglobulin and resistance training for 1 wk prior to 5 d of limb immobilisation will attenuate the decrease in integrated muscle protein synthesis, muscle fibre CSA, quadriceps muscle strength, and leg lean mass during muscle disuse.

2. Combining β-lactoglobulin and resistance training for 1 wk prior to 5 d of limb immobilisation will attenuate the decrease in muscle fibre CSA, quadriceps muscle strength, and leg lean mass during muscle disuse.
