Context:
Resistance exercise training has recently been considered as an effective type of training to increase energy metabolism and insulin sensitivity. However, mechanisms of the resistance training-induced improvements in energy metabolism and insulin sensitivity have not been fully understood. Zinc-α2-glycoprotein (ZAG), which is a novel adipokine, has beneficial effects on energy metabolism and insulin sensitivity.
Objective:
We investigated the effect of a single bout of resistance exercise on the ZAG concentration.
Methods:
Nine healthy men were enrolled. They performed a single bout of resistance exercise (bench press and leg press) consisting of 10 repetitions of five sets at 70% of maximum strength with 90-s rests in between sets. Blood samples were obtained before and after acute resistance exercise to measure the ZAG concentration.
Results:
The serum ZAG concentration significantly increased following acute resistance exercise.
Conclusion:
This result suggests that a single bout of resistance exercise may enhance the ZAG concentration.
