• Registration Number: NCT06465407
• Lead Sponsor: University of Central Florida

Brief Summary

This study is focused on exploring the gap in the literature by comparing the effects of collagen protein versus placebo supplementation on the musculotendinous unit following muscle damaging protocol. Thus, the purpose of this study is to identify and compare the effect of collagen protein versus placebo supplementation on indirect markers of musculotendinous unit recovery following eccentric calf exercises.

Detailed Description

Various physical assessments that include pain scale, pain pressure threshold assessment, body composition, calf circumference measurements, muscle thickness measurements, Achilles tendon length and thickness measurements, myotonography of the calf, isometric force assessments during standing and seated plantarflexion positions, a heel raise test, and a standardized exercise routine focused on eccentric movements, targeting a leg chosen at random. Additionally, will consume a daily dose of two 30-g amount of collagen peptides derived from bovine hide (commercially available as Vital Proteins or Peptan) or placebo (30 g of pure maltodextrin with no amino acids) mixed in 300 ml of orange Gatorade zero.

Gatorade zero, maltodextrin, and collagen is going to be stored in the locked cabinet in the lab. Research team will mix the supplement (placebo or maltodextrin) with Gatorade zero in a non-clear bottle and will administer it to the participants on-site.

Arm && Interventions

Group	Intervention	Description
Collagen	Collagen	Collagen supplementation group will have 12 participants. They will perform various physical assessments that include pain scale, pain pressure threshold assessment, body composition, calf circumference measurements, muscle thickness measurements, Achilles tendon length and thickness measurements, myotonography of the calf, isometric force assessments during standing and seated plantarflexion positions, a heel raise test, and a standardized exercise routine focused on eccentric movements, targeting a leg chosen at random. Additionally, they will consume a daily dose of two 30-g amount of collagen peptides derived from bovine hide (commercially available as Vital Proteins or Peptan).
Placebo	Maltodextrin	Placebo supplementation group will have 12 participants. They will perform various physical assessments that include pain scale, pain pressure threshold assessment, body composition, calf circumference measurements, muscle thickness measurements, Achilles tendon length and thickness measurements, myotonography of the calf, isometric force assessments during standing and seated plantarflexion positions, a heel raise test, and a standardized exercise routine focused on eccentric movements, targeting a leg chosen at random. Additionally, they will consume a daily dose of placebo (two 30 g of pure maltodextrin with no amino acids) mixed in 300 ml of orange Gatorade zero.

Primary Outcome Measures

Name	Time	Method
Calf muscle thickness	5 days	Portable B-mode Ultrasound (GE Logiq e BT12, GE Healthcare, Milwaukee, WI, USA) and a multi-frequency linear- array probe (12 L-RS, 5-13 MHz, 38.4-mm field of view, GE Healthcare, Milwaukee, WI, USA) will be used to determine changes in muscle thickness of the randomized leg. The distance between the medial point of the knee joint space and the central point of the medial malleolus will be measured at 70% and ultrasound gel will be placed on this location prior to measurement. The highest and mean values of 3-5 measurements will be recorded for each assessment. All measurements will be done on one randomized leg.

Secondary Outcome Measures

Name	Time	Method
Achilles tendon thickness.	5 days	Achilles tendon will be scanned using a B-mode US imaging device (GE Logiq e, GE Healthcare,Wauwatosa, WI, USA) and a multi-frequency linear-array probe (12 L-RS, 5-13 MHz, 38.4-mm field of view; GE Healthcare). The same researcher will perform the assessments. All ultrasound imaging analyses will be performed using Image-J software 1.8.0 (National Institute of Health, Bethesda, MD, USA). Achilles tendon length will be determined using the segmented line function between calcaneal notch and muscle-tendon junction along the midline of the Achilles tendon. Additionally, sagittal images of the Achilles tendon will be collected with the ankle passively dorsiflexed to approximately 90 degrees. Tendon thickness will be measured at reference point of 2 cm proximal to the superior aspect of the calcaneus.
