  • No detected effect on handgrip strength (hand dynamometer)

    moderate

    “Regarding the effect of whey protein intake on handgrip strength, the data showed no difference compared with the control intervention, as shown in Figure 4 (p = 0.171; Z = 1.369; CI 95%: −0.055–0.309).”
    Population
    Community-dwelling older adults (over 60 years) with sarcopenia diagnosed mainly by EWGSOP criteria; ten randomised trials, handgrip by dynamometry in seven
  • No detected effect on body mass

    moderate

    “Regarding the effect of whey protein intake on physical performance, the data showed that there were no changes in weight, as shown in Figure 10 (p = 0.140; Z = 1.477; CI 95%: −0.032–0.230).”
    Population
    Community-dwelling older adults (over 60 years) with sarcopenia; ten randomised trials, whey protein vs placebo
