Brief Summary

In order to examine the effect of RIPC on skeleton muscle exertional damage and on aerobic and anaerobic physical performances, 30 healthy volunteers will undergo a series of different physical tests twice; once without intervention and a second time with RIPC intervention or placebo (false) intervention.

Outcome Measures

Primary Outcomes (1)

  • creatine phosphokinase (CPK)

    CPK is a marker for muscle damage assessed in blood test. blood sample will be taken before and after step test, anaerobic test and time to exhaustion test.

    6 experiment days for each participant

Secondary Outcomes (8)

  • oxygen consumption (VO2)

    6 experiment days for each participant

  • heart rate variability (HRV)

    6 experiment days for each participant

  • lactic acid

    6 experiment days for each participant

  • blood count

    6 experiment days for each participant

  • apolipoprotein A1 (APO-A1) levels

    6 experiment days for each participant

  • +3 more secondary outcomes

Study Arms (2)

RIPC intervention group

ACTIVE COMPARATOR

The experiment protocol consist 2 series (with a month between them), both series include the described 3 days: Day 1 - anthropometry measurements and VO2max test (BRUCE protocol). Day 2 - steps test (heled protocol). Day 3 - anaerobic test (wingate protocol), 1 hour rest and time to exhaustion test (heled protocol). the second series will be performed after RIPC intervention exposure at the beginning of every meeting.

Procedure: RIPC intervention exposure

false exopsure group

PLACEBO COMPARATOR

The experiment protocol consist 2 series (with a month between them), both series include the described 3 days: Day 1 - anthropometry measurements and VO2max test (BRUCE protocol). Day 2 - steps test (heled protocol). Day 3 - anaerobic test (wingate protocol), 1 hour rest and time to exhaustion test (heled protocol). the second series will be performed after placebo intervention exposure at the beginning of every meeting.

Procedure: placebo intervention exposure

Interventions

placing a sphygmomanometer on the non-dominant hand and applying pressure of 200 mmHg for 5 min followed by 5 min without pressure X 4 repeats

RIPC intervention group

placing a sphygmomanometer on the non-dominant hand and applying pressure of 100 mmHg for 5 min followed by 5 min without pressure X 4 repeats.
