We investigated changes in functional fitness after an exercise program in combination with Calanus oil supplementation, a novel source of bioactive lipids rich in wax esters with omega-3 polyunsaturated fatty acid (n-3 PUFA). Fifty-five healthy sedentary women aged 65-80 (mean age 70.9 ± 3.9 years, BMI 27.24 ± 3.9 kg m, VOpeak 19.46 ± 3.7 ml kg min) were enrolled in the study. The participants were divided into two groups: exercise training plus Calanus Oil supplementation ( = 28) or exercise plus placebo (sunflower oil) supplementation ( = 27). The exercise intervention program was completed by 53 participants and contained functional circuit training (twice a week, 45 min plus 15 min of stretching and balance training) and Nordic walking (once a week, 60 min) for 16 weeks. Senior fitness test, exercise stress test on bicycle ergometer, hand-grip, and body composition were evaluated before and after the program. Our results show that functional fitness and body composition improved following the interventional exercise program, but for most of the parameters there was no synergic effect of supplementing n-3 PUFA-rich Calanus oil. In comparison to the placebo group, the group with Calanus supplementation experienced significantly higher improvement of functional strength of lower body which was evaluated by the chair stand test. Supplementation with Calanus may have a synergic effect with exercise on functional strength of the lower body in the elderly.
我们研究了在锻炼计划中结合 Calanus 油补充剂（一种富含蜡酯的生物活性脂质的新型来源，其中含有 ω-3 多不饱和脂肪酸（n-3 PUFA））后，功能性体能的变化。55 名年龄在 65-80 岁（平均年龄 70.9 ± 3.9 岁，BMI 27.24 ± 3.9 kg m，VOpeak 19.46 ± 3.7 ml kg min）的健康久坐女性参加了这项研究。参与者被分为两组：运动训练加 Calanus 油补充剂（= 28）或运动加安慰剂（葵花籽油）补充剂（= 27）。运动干预计划由 53 名参与者完成，包括功能性电路训练（每周两次，每次 45 分钟，外加 15 分钟的伸展和平衡训练）和北欧步行（每周一次，每次 60 分钟），共 16 周。在计划前后评估了高级体能测试、自行车测力计运动应激测试、握力和身体成分。我们的结果表明，功能性体能和身体成分在干预性运动计划后得到了改善，但对于大多数参数，补充富含 n-3 PUFA 的 Calanus 油没有协同作用。与安慰剂组相比，补充 Calanus 组的下肢功能性力量明显提高，这是通过坐立测试评估的。补充 Calanus 可能与老年人下肢功能性力量的运动有协同作用。
