PURPOSE: Effects of resvenatrol (RE) on lowering blood fats have been claimed in several studies. A population who could benefit from the intake of resvenatrol are the recreational cyclists. Any studies existing at present time about the effect of resvenatrol in recreational cyclists (Braakhuis et. al 2015). Our aim was to investigate the effect of prolonged (28 days, 1g/day) supplementation of RE in recreational well trained amateur cyclists on body weight, plasma lipids and basic hematological parameters, blood pressure, lactate and exercise fatigue perception. METHODS: 20 recreational cyclists (mean age 38,7±9 years for resvenatrol group, RE = n. 9, and and 31,3±8,6 years for placebo groups, PL = n.11) were evaluated for basic hematological parameters, lactate, blood pressure, and fatigue perception, before and after acute (1g, 30 min before a maximal trial) and long term assumption (4 weeks) of 1g/die of resvenatrol (before and after a 1 hour exhaustion trial). RESULTS: no changes in blood pressure was observed in the long term (RE group 111±13/81±13 and 116±8/82±10; PL group 116±18/84±13 and 114±30/78±20, respectively at day-0 and day-28). No changes in body weight were observed (74,46±7.14 kg at day 0 and 75,9± 6,8 at day 28 in RE group; 73,96± 6,55 kg at day 0 and 73,78± 5,87 at day 28 in PL group). Scores in the Borg visual analog scale was: 19±1 at day 0 and 18±2 at day 28, for PL group, while RE group scored 19±1 and 18±2 without any significant pre-post differences and between groups. Total cholesterol showed a larger decrease on the long term in the RE group: 181.44±23.77 vs 141.75±52.67 (p= 0.10) in the RE compared to 185.80±23.59 vs 81.67±20.31 (p=0.48), day 0 and day 28, while LDL significantly decreased only in the RE group: 86.11±18.26 vs 75.67±17.85 (p=0.19) for RE, and 93.08±15.68 vs 90.14±15.76 (p=0.68) in the PL group. CONCLUSION: main effect of resvenatrol was in controlling fat markers in blood on the long term (4 weeks) with 1g/day ingestion.

Abstract
PURPOSE: Effects of resvenatrol (RE) on lowering blood fats have been claimed in several studies. A population who could benefit from the intake of resvenatrol are the recreational cyclists. Any studies existing at present time about the effect of resvenatrol in recreational cyclists (Braakhuis et. al 2015). Our aim was to investigate the effect of prolonged (28 days, 1g/day) supplementation of RE in recreational well trained amateur cyclists on body weight, plasma lipids and basic hematological parameters, blood pressure, lactate and exercise fatigue perception. METHODS: 20 recreational cyclists (mean age 38,7±9 years for resvenatrol group, RE = n. 9, and and 31,3±8,6 years for placebo groups, PL = n.11) were evaluated for basic hematological parameters, lactate, blood pressure, and fatigue perception, before and after acute (1g, 30 min before a maximal trial) and long term assumption (4 weeks) of 1g/die of resvenatrol (before and after a 1 hour exhaustion trial).
