The aim of the study was to assess the effect of a 3-month pre-season preparatory period and shortterm moderate aerobic exercise and intensive fitness and speed exercise on adipokine and ghrelin levels in young female handball and basketball players.
Fifty healthy young female professional basketball and handball players were enrolled into the study before the opening of the season (after a 2-month holiday with no training or dietary restrictions). Serum estradiol and plasma leptin, adiponectin, visfatin, and ghrelin levels were determined at the beginning and the end of a 3-month period of moderate aerobic training. Plasma adipokines and ghrelin levels were additionally assessed after 2 h of moderate aerobic exercise or after intensive fitness and speed exercise training.
Long-term moderate aerobic exercise was followed by a significant decrease in plasma ghrelin and leptin levels (921±300 vs 575±572 pg/ml, p<0.001 and 16.4±15.6 vs 11.8±16.3 ng/ml, p<0.01, respectively); plasma adiponectin and visfatin remained unchanged. No changes were observed in plasma ghrelin and leptin levels after short-term moderate aerobic exercise or after intensive fitness and speed exercise. Plasma visfatin concentration increased significantly after short-term moderate aerobic exercise (22.1±8.7 vs 27.6±9.0 ng/ml, p<0.001), whilst adiponectin increased after intensive fitness and speed exercise (16.7±7.8 vs 21.0±9.8 μg/ml, p<0.001).
Regular moderate aerobic training in preparation for the match season is followed by a decline in circulating leptin and ghrelin levels even in athletes without body weight changes. Short-term intensive fitness and moderate aerobic exercise seem to modulate the production of different adipokines.
本研究旨在评估为期 3 个月的赛季前准备期和短期中等强度有氧运动以及强化体能和速度训练对年轻女性手球和篮球运动员的脂肪因子和 ghrelin 水平的影响。
在赛季开始前(经过 2 个月没有训练或饮食限制的假期后),招募了 50 名健康的年轻女性职业篮球和手球运动员参与本研究。在 3 个月的中等强度有氧运动期间的开始和结束时,测定血清雌二醇和血浆瘦素、脂联素、内脂素和 ghrelin 水平。在中等强度有氧运动后 2 小时或强化体能和速度训练后,另外评估血浆脂肪因子和 ghrelin 水平。
长期中等强度有氧运动后,血浆 ghrelin 和 leptin 水平显著下降(921±300 对 575±572 pg/ml,p<0.001 和 16.4±15.6 对 11.8±16.3 ng/ml,p<0.01);血浆脂联素和内脂素保持不变。短期中等强度有氧运动或强化体能和速度训练后,血浆 ghrelin 和 leptin 水平无变化。短期中等强度有氧运动后,血浆内脂素浓度显著升高(22.1±8.7 对 27.6±9.0 ng/ml,p<0.001),而强化体能和速度训练后,脂联素升高(16.7±7.8 对 21.0±9.8 μg/ml,p<0.001)。
在为比赛季节做准备时,定期进行中等强度有氧运动可降低循环瘦素和 ghrelin 水平,即使运动员的体重没有变化。短期强化体能和中等强度有氧运动似乎调节了不同脂肪因子的产生。
