Interventions/Control_1

Intake of Test sample A (containing high citric acid) before exercise >> wash out period (at least3 day) >> Intake of Test sample B (containing low citric acid) before exercise >> wash out period (at least3 day) >> Intake of placebo before exercise >> wash out period (at least3 day) >>

Intake of Test sample A (containing high citric acid) after exercise >> wash out period (at least3 day) >> Intake of Test sample B (containing low citric acid) after exercise >> wash out period (at least3 day) >> Intake of placebo after exercise

The subjects carry out exercise by using cycle ergometer for 15 min at 50 % of maximum exercise intensity and for 20 min at 70 % of maximum exercise intensity.

Interventions/Control_2

Intake of Test sample B before exercise >> wash out period (at least3 day) >> Intake of placebo before exercise >> wash out period (at least3 day) >> Intake of Test sample A before exercise >> wash out period (at least3 day) >>

Intake of Test sample B after exercise >> wash out period (at least3 day) >> Intake of placebo after exercise >> wash out period (at least3 day) >> Intake of Test sample A after exercise

The subjects carry out exercise by using cycle ergometer for 15 min at 50 % of maximum exercise intensity and for 20 min at 70 % of maximum exercise intensity.

Interventions/Control_3

Intake of placebo before exercise >> wash out period (at least3 day) >> Intake of Test sample A before exercise >> wash out period (at least3 day) >> Intake of Test sample B before exercise >> wash out period (at least3 day) >>

Intake of placebo after exercise >> wash out period (at least3 day) >> Intake of Test sample A after exercise >> wash out period (at least3 day) >> Intake of Test sample B after exercise

The subjects carry out exercise by using cycle ergometer for 15 min at 50 % of maximum exercise intensity and for 20 min at 70 % of maximum exercise intensity.

Interventions/Control_4

Intake of Test sample B (containing low citric acid) before exercise >> wash out period (at least 7 day) >> Intake of placebo before exercise

The subjects carry out exercise by using cycle ergometer for 15 min at 50 watt exercise intensity and for 20 min at 70 watt exercise intensity.

Interventions/Control_5

Intake of placebo before exercise >> wash out period (at least 7 day) >> Intake of Test sample B (containing low citric acid) before exercise

The subjects carry out exercise by using cycle ergometer for 15 min at 50 watt exercise intensity and for 20 min at 70 watt exercise intensity.
