Study Details

Study Description

Brief Summary

The serum concentration of cartilage oligomeric matrix protein (sCOMP) has been considered a mechano-sensitive biomarker of articular cartilage turnover, and N-propeptide of type II collagen (PIIANP) is a proposed biomarker of type II collagen synthesis. Few studies have investigated both the anabolic and turnover response of articular cartilage as a result of acute changes in body weight mass during exercise. Using a repeated measures cross-over design, fifteen healthy adults (age 18-30 years) performed three, 30-minute bouts of treadmill walking exercise under 3 loading conditions: (1) control (no alteration to body mass); (2) loaded (12% increase in body mass using a weighted vest); and (3) unloaded (12% decrease in body mass using lower body positive pressure). Venous blood was collected before, immediately after, and 15 and 30 minutes after exercise to investigate cartilage turnover (sCOMP) and anabolism (PIIANP).

Arms and Interventions

Arm Intervention/Treatment
Experimental: Control

The control condition did 30 minutes of walking exercise with their own body mass.

Other: Control Condition
Control (no alteration to body mass).

Experimental: +12% Body Mass

The +12% body mass condition did 30 minutes of walking exercise wearing a weighted vest with +12% of their body mass applied.

Other: +12% Body Mass
Loaded walking exercise (12% increase in body mass using a weighted vest).

Experimental: -12% Body Mass

The -12% body mass condition did 30 minutes of walking exercise using a lower body positive pressure treadmill with -12% of their body mass applied.

Other: -12% Body Mass
Unloaded walking exercise (12% decrease in body mass using lower body positive pressure).

Outcome Measures

Primary Outcome Measures

  1. Serum cartilage oligomeric matrix protein (sCOMP) [sCOMP was measured at baseline, immediately post, and 15- and 30-minutes post exercise.]

    The systemic blood serum concentration of sCOMP was evaluated in all participants under the 3 conditions in a crossover trial.

  2. N-propeptide of type II collagen (PIIANP) [PIIANP was measured at baseline, immediately post, and 15- and 30-minutes post exercise.]

    The systemic blood serum concentration of PIIANP was evaluated in all participants under the 3 conditions in a crossover trial.
