■运动对健康有益,但可引起氧化应激和炎症,特别是在高强度形式,如高强度间歇运动(IIIE)。Exragaming已经成为一种有效的,适合所有年龄段的健身工具,尤其是老年人。酶补充剂可以通过改善乳酸代谢和减少氧化应激来增强运动表现。
■这项研究调查了水果和蔬菜酶补充剂在调节HIIE后老年人的疲劳和增强有氧能力方面的功效。
■该研究招募了16名年龄较大的成年女性参与者,并根据他们的预测乳酸水平将他们分为2个不同的组(酶和安慰剂)。这种划分使用成对分组来保证组之间的可比性,确保结果的完整性。他们使用任天堂SwitchRingFitAdventure从事HIIE,进行8组20秒的最大努力运动,穿插30秒的休息,总共370秒的锻炼。评估的关键指标包括血乳酸水平,心率,感知努力的评级,和训练冲动。酶组的参与者在14天内每天两次以30mL的剂量给予水果和蔬菜酶补充剂。
■与安慰剂组相比,酶组血乳酸水平明显降低,特别是在第四次(平均4.29,SD0.67与平均6.34,SD1.17mmol/L;P=.001)和第八次(平均5.84,SD0.63与平均8.20,SD1.15mmol/L;P<.001)运动之后。这种趋势在运动后5分钟(平均6.85,SD0.82与平均8.60,SD1.13mmol/L;P=.003)和10分钟(平均5.91,SD1.16与平均8.21,SD1.27mmol/L;P=.002)持续。尽管两组在运动过程中都超过了其估计最大心率的85%,补充酶没有明显影响感知的强度或努力。
■该研究表明,水果和蔬菜酶补充剂可以通过运动游戏显着降低HIIE后老年人的血乳酸水平。这表明这些酶在调节高强度运动期间和之后的乳酸产生或清除中的潜在作用。这些发现对制定有针对性的干预措施以增强老年人的运动耐量和康复具有重要意义。
UNASSIGNED: Exercise offers substantial health benefits but can induce oxidative stress and inflammation, especially in high-intensity formats such as high-intensity interval exercise (HIIE). Exergaming has become an effective, enjoyable fitness tool for all ages, particularly older adults. Enzyme supplements may enhance exercise performance by improving lactate metabolism and reducing oxidative stress.
UNASSIGNED: This study investigates the efficacy of fruit and vegetable enzyme supplementation in modulating fatigue and enhancing aerobic capacity in older adults following HIIE through exergaming.
UNASSIGNED: The study recruited 16 older adult female participants and allocated them into 2 distinct groups (enzyme and placebo) based on their pretest lactate levels. This division used pairwise grouping to guarantee comparability between the groups, ensuring the integrity of the results. They engaged in HIIE using Nintendo Switch Ring Fit Adventure, performing 8 sets of 20 seconds of maximum effort exercise interspersed with 30 seconds of rest, totaling 370 seconds of exercise. Key metrics assessed included blood lactate levels, heart rate, rating of perceived exertion, and training impulse. Participants in the enzyme group were administered a fruit and vegetable enzyme supplement at a dosage of 30 mL twice daily over a period of 14 days.
UNASSIGNED: The enzyme group showed significantly lower blood lactate levels compared to the placebo group, notably after the fourth (mean 4.29, SD 0.67 vs mean 6.34, SD 1.17 mmol/L; P=.001) and eighth (mean 5.84, SD 0.63 vs mean 8.20, SD 1.15 mmol/L; P<.001) exercise sessions. This trend continued at 5 minutes (mean 6.85, SD 0.82 vs mean 8.60, SD 1.13 mmol/L; P=.003) and 10 minutes (mean 5.91, SD 1.16 vs mean 8.21, SD 1.27 mmol/L; P=.002) after exercise. Although both groups exceeded 85% of their estimated maximum heart rate during the exercise, enzyme supplementation did not markedly affect the perceived intensity or effort.
UNASSIGNED: The study indicates that fruit and vegetable enzyme supplementation can significantly reduce blood lactate levels in older adults following HIIE through exergaming. This suggests a potential role for these enzymes in modulating lactate production or clearance during and after high-intensity exercise. These findings have implications for developing targeted interventions to enhance exercise tolerance and recovery in older adults.
