■作为增强骨骼肌健康的一种相对新颖的方法,混合蛋白质补充剂对乳清蛋白的反应相似。然而,以前没有研究过它对高尔夫挥杆性能的影响。这项研究旨在研究混合蛋白质补充剂对休闲高尔夫球手的挥杆性能和肌肉力量的影响。
■招募了60名障碍小于20的参与者,并随机分配给双盲,安慰剂对照研究设计。参与者分为两组:混合蛋白组(MG,n=30),和安慰剂对照组(CG,n=30)。他们被指示摄取含有酪蛋白钙的补充剂,乳清蛋白,和分离的豌豆蛋白,或者安慰剂,每天一次,共8周。前测和后测包括人体测量,肌肉力量(等速膝关节和躯干力量,和握力),2分钟俯卧撑,balance,和高尔夫挥杆性能使用驱动程序和7号铁。
■经过8周的补充期,ANCOVA,使用基线值作为协变量,显示驾驶员距离(p=.004)和驾驶员球速度(p<.001)存在显着差异。MG显著增加驾驶员距离5.17±12.8m(p=.046),驱动球速度为1.36±2.87m/s(p=.021)。此外,在手握力方面观察到显着改善(2.12±3.47kg,p=.004),两分钟俯卧撑(4.89±8.14代表,p=.004),和平衡评分(-0.37±0.69分钟,p=.009)。在身体组成参数中没有观察到显著差异(p>.05)。
■摄入含有动物和植物蛋白的混合蛋白对高尔夫性能和肌肉功能具有积极作用。因此,混合蛋白质可能代表了增强高尔夫运动员骨骼肌健康的安全有效方法。
UNASSIGNED: As a relatively novel approach to enhancing skeletal muscle health, mixed protein supplementation has shown similar responses to whey protein. However, no previous studies have examined its impact on
golf swing performance. This study aimed to examine the effect of mixed protein supplementation on the swing performance and muscle strength of casual golfers.
UNASSIGNED: Sixty participants with a handicap of less than 20 were recruited and randomly assigned to a double-blind, placebo-controlled study design. The participants were divided into two groups: a mixed protein group (MG, n = 30), and a placebo control group (CG, n = 30). They were instructed to ingest either a supplement containing casein calcium, whey protein, and isolated pea protein, or a placebo, once daily for 8 weeks. Pre- and posttests consisted of anthropometric measurements, muscle strength (isokinetic knee and trunk strength, and handgrip strength), 2-minute push-ups, balance, and
golf swing performance using a driver and 7-iron.
UNASSIGNED: After the 8-week supplementation period, ANCOVA, using baseline values as covariates, revealed significant differences for driver distance (p = .004) and driver ball speed (p < .001). MG significantly increased driver distance by 5.17 ± 12.8 m (p = .046), driver ball speed by 1.36 ± 2.87 m/s (p = .021). Additionally, significantly improvements were observed in hand grip strength (+2.12 ± 3.47 kg, p = .004), two-minute push-ups (+4.89 ± 8.14 reps, p = .004), and balance score (-0.37 ± 0.69 min, p = .009). No significant differences were observed in body composition parameters (p > .05).
UNASSIGNED: The intake of a mixed protein containing both animal and plant proteins had positive effects on
golf performance and muscle function. Therefore, mixed proteins may represent a safe and effective approach to enhancing skeletal muscle health in
golf players.
