The study aimed to assess responsiveness to the effects of acute caffeine intake after 8 weeks of Pilates intervention in healthy older adults.
Fifteen healthy older adults performed physical performance regarding daily practice, strength, and balance tests after ingestion of acute 5 mg/kg of caffeine or placebo before and after Pilates training.
The caffeine intake reduced, regardless of Pilates training, the time in 10-m walk test (before placebo vs caffeine, 6.48 ± 0.70 vs 6.51 ± 0.82 seconds; after placebo vs caffeine, 5.84 ± 0.70 vs 5.48 ± 0.61 seconds; = .008; η = 0.404) and timed up and go test (before placebo vs caffeine, 26.30 ± 1.82 vs 24.37 ± 2.12 seconds; after placebo vs caffeine, 22.96 ± 2.36 vs 22.49 ± 2.27 seconds; = .002; η = 0.517) compared with the placebo. Participants were not less responsive to caffeine intake in the 10-m walk test (ΔPre vs ΔPost, -0.33 ± 0.66 vs -0.36 ± 0.53 seconds; = .888), but they were less responsive for the timed up and go test (ΔPre vs ΔPost, -1.92 ± 2.06 vs -0.47 ± 1.15 seconds; = 0.030) after Pilates intervention. There were no differences for the sit-to-stand test, rising from the floor, dress and undress T-shirt, handgrip strength, and balance variables.
Although the caffeine improved on the 10-m walk test and timed up and go test performance, healthy older adults were less responsive to caffeine after Pilates training only for performance on the timed up and go test.
本研究旨在评估普拉提干预8周后，健康老年人急性摄入咖啡因后的反应性。
15名健康老年人在普拉提训练前后分别摄入5mg/kg的急性咖啡因或安慰剂，之后进行日常活动能力、力量和平衡测试。
无论是否进行普拉提训练，与安慰剂相比，摄入咖啡因后10米步行测试时间缩短（安慰剂前vs咖啡因前，6.48±0.70秒vs6.51±0.82秒；安慰剂后vs咖啡因后，5.84±0.70秒vs5.48±0.61秒；P=.008；η=0.404），定时起立行走测试时间也缩短（安慰剂前vs咖啡因前，26.30±1.82秒vs24.37±2.12秒；安慰剂后vs咖啡因后，22.96±2.36秒vs22.49±2.27秒；P=.002；η=0.517）。参与者在10米步行测试中对咖啡因摄入的反应性没有降低（干预前变化量vs干预后变化量，-0.33±0.66秒vs-0.36±0.53秒；P=.888），但在普拉提干预后，他们在定时起立行走测试中的反应性降低（干预前变化量vs干预后变化量，-1.92±2.06秒vs-0.47±1.15秒；P=0.030）。坐立试验、从地面起身、穿脱T恤、握力和平衡变量方面没有差异。
尽管咖啡因改善了10米步行测试和定时起立行走测试的表现，但仅在定时起立行走测试的表现上，健康老年人在普拉提训练后对咖啡因的反应性降低。
