本研究目的在探討補充7－12天綠藻後，對恢復期肌肉損傷與最大肌力的影響。招募臺北醫學大學羽球校隊共24名球員作為受試者。本研究採雙盲、隨機設計（double-blind and randomized design）分為安慰劑組與綠藻組。所有受試者需口服12天高劑量綠藻（9克／天）或安慰劑後，於口服第7天時施做三項阻力運動誘發肌肉損傷，於口服第8、9天時分析恢復期第24、48小時之肌肉損傷、肌肉酸痛及肝功能等指數，於口服第10、11、12天時分析恢復期第3、4、5天之三項肌力變化。研究結果顯示：阻力運動後第24小時綠藻組之肌酸激酶（creatine kinase）活性明顯較安慰劑組為低；恢復期第3天之大腿推蹬、大腿屈曲及第4天之胸部推舉肌力表現，綠藻組較安慰劑組明顯提升；肌肉酸痛指數部分，與前測相較，兩組第24、48小時均顯著增加。而乳酸脫氫酶（lactate dehydrogenase）、丙胺酸轉胺酶（alanine aminotransferase）、天門冬胺酸轉胺酶（aspartate aminotransferase）活性與肌肉酸痛指數，兩組間則未達顯著差異。本研究結論：短期7－12天補充高劑量綠藻後，可抑制阻力運動後之肌肉損傷與提升恢復期上、下肢的最大肌力表現，此外，對肝功能並無損傷。

This study aimed to investigate the effects of Chlorella supplementation for 7-12 days on muscle damage and maximal muscle strength during the recovery period after exercise. Twenty-four badminton players from Taipei Medical University were recruited as subjects and divided into the placebo or Chlorella group in a randomized, double-blind, placebo-controlled designed study. All subjects were orally given high-dose Chlorella (9 g/day) or placebo for 12 days, and performed three different resistance exercises to induce muscle damage after 7-day oral administration. Muscle damage, muscle soreness and liver function markers were determined 24 and 48 hours after resistance exercise., Three tests of muscle strength were also measured on the 3rd, 4th and 5th day during the recovery period (the 10th, 11th, 12th day after oral administration). The results showed that the blood creatine kinase activity was relatively lower at 24 hours after resistance exercise in Chlorella group than that of placebo group. The muscle strength of leg press and leg curl on 3rd day and chest press on 4th day during the recovery period in the Chlorella group were significantly higher compared to the placebo group, and the muscle soreness were significantly greater compared to pre-teat for both groups. However, the activities of lactate dehydrogenase, alanine aminotransferase and aspartate aminotransferase, and muscle soreness index were not significantly different between the two groups. In conclusion, short-term with high-dose Chlorella supplementation for 7-12 days inhibited resistance exercise-induced muscle damage, and improved the muscle strength performance of upper and lower body during recovery. In addition, no damage to liver function markers was found in this study.
