Post exercise postures and intensity on rate of recovery after short term high intensity exericse
Abstract:
The purposes of this study were to investigate effects of post-exercise posture
and intensity on rate of recovery after short term high intensity exercise. Ten healthy
male volunteers, aged 20-25 years, performed the Wingate test for 30 seconds. Three
recovery modes, including two passive recovery modes [upright sitting (PR1) and
supine with raised legs (PR2)] and an active recovery mode [cycling (AR) with zero
resistance at 50-60 rpm], were randomly selected following exercise. The rate of
recovery was indicated by blood lactate concentration (BLC), heart rate (HR), blood
pressure (BP), respiratory rate (RR), rate-pressure product (RPP), mean arterial
pressure (MAP), rating of perceived exertion (RPE) and thermal sensation scale (TS),
which were measured at rest, immediately after exercise and 5, 10, 20 and 30 minute
(T5, T10, T20, T30) after exercise cessation.
It was found that different recovery modes influenced the rate of lactate
removal, where the highest mean BLC was found at T5 in PR1 and PR2, and T10 in
AR mode. Active recovery after high intense exercise resulted in a greater removal of
BLC than PR1 and PR2 observed during 20-30 minutes. PR2 ineffectively enhanced
lactate removal. Cardio-respiratory variables: HR, RR and RPP were lower in passive
recovery modes (PR1 and PR2) than AR mode. No significant differences in systolic,
diastolic, and mean blood pressures (SBP, DBP, MAP), RPE and TS between the three
modes was found. It is concluded that a 30 minute recovery period after short term
high intense exercise is not enough to proof a full recovery of lactate and cardiac
functions.
