摘要

目的：本研究旨在探討在為期4 週的輕艇訓練期間增補牛初乳是否會影響輕艇選手的運動表現、白血球數量、嗜中性白血球數量、淋巴細胞數量、淋巴細胞次群比例及數量、唾液IgA 濃度及分泌量。方法：本研究以22 位自願參加的男性輕艇選手為受試者（年齡：15.90 ± 2.31 歲；身高：172.24 ± 5.59 公分；體重：63.30 ± 6.95 公斤；體脂肪百分比：13.77 ± 3.76%）。本研究採雙盲設計。受試者依運動表現分配至牛初乳增補組（BC，每天20 克，n = 11）或安慰劑組（PL，n = 11）。在增補期前、後，受試者皆接受身體組成及輕艇測功儀運動表現檢測，增補第1 天訓練前、後（Pre-rest & Pre-post）及第28天訓練前、後（Post-rest & Post-post）採集血液及唾液樣本。本研究採用混合設計二因子變異數分析（組別 × 時間）考驗牛初乳增補前後之運動表現、身體組成、血液及唾液樣本中之生物參數，若有交互作用則以最小顯著差異法（least significant difference, LSD）進行事後比較，顯著水準訂為α = .05。結果：受試者在4 週的專項訓練後，運動表現、體重及體脂肪百分比於兩組之間無顯著差異；白血球數量、嗜中性白血球數量、淋巴細胞數量、淋巴細胞次群（CD4+、CD8+、CD19+、CD56+）及CD4 ／CD8 比值均無組間差異。唾液流量及唾液IgA 濃度無顯著變化，惟安慰劑組的IgA 流量顯著高於前測（0.08 ± 0.05vs. 0.12 ± 0.08 mg/min, p ＜ .05）。結論：為在為期4 週的輕艇訓練期間，每日增補20 克牛初乳不會對輕艇運動表現、身體組成、白血球、嗜中性白血球、淋巴細胞、淋巴細胞次群比例及數量、唾液IgA 濃度及分泌量造成影響。

Purpose: This study aimed to examine the effects of bovine colostrums (BC) supplementation during a 4-week canoe/kayak training program on blood lymphocyte subsets and saliva immunoglobulin A (IgA). Methods: Twenty-two well-trained male kayak athletes (age 15.90 ± 2.31 years, height 172.24 ± 5.59 cm, body mass 63.30 ± 6.95 kg, body fat 13.77 ± 3.76%) were voluntarily participated in this study. This study used double-blind design. Participants were paired by performance then assigned into BC supplementation group (BC, 20 g each day) or placebo group (PL). Before and after supplement, participants were asked to assess body composition and performance on kayak ergometry. Blood and saliva samples were collected pre-supplementation (Pre-rest & Pre-post) as well as post-supplementation (Post-rest and Post-post) at first and 28th day respectively. A mixed-design two-way (groups × time) ANOVA was adopted with post hoc least significant difference (LSD). Statistical significance was set at α = .05. Results: There were no significant difference in body composition, exercise performance, blood counts of leukocyte, lymphocyte and neutrophil, percentages and counts of CD4^+, CD8^+, CD19^+, CD56^+ lymphocytes, and CD4/CD8 ratio between the two groups. Significantly higher IgA flow rate at Post-Pre than that at Pre in PL group was observed (0.08 ± 0.05 vs. 0.12 ± 0.08 mg/min, p ＜ .05). Conclusion: The findings of this study suggested that the a 4-week BC supplementation during training period not changed exercise performance, body composition, leukocyte, lymphocyte subsets and saliva immunoglobulin A (IgA) in canoe/kayak athletes.
