What did studies of High-intensity strength training find?

4

Studies of High-intensity strength training measured 4 outcomes; the most studied are six-minute walk test distance (1 study), SF-36 physical function score (1) and berg Balance Scale (1).

Six-minute walk test distance

upin humans1

1 study

  1. High-intensity strength training improves six-minute walk test distance in humans after hip fracture (MD = 83.32, 95%CI 46.73 to 119.91).

    “The result showed that the 6MWT was significantly longer in the training group (MD = 83.32, 95%CI 46.73 to 119.91, Z = 4.46, P < 0.00001).”

  1. High-intensity strength training improves SF-36 physical function score in humans after hip fracture (MD = 16.31, 95%CI 4.92 to 27.69).

Berg Balance Scale

1 study

  1. High-intensity strength training improves berg Balance Scale in humans after hip fracture (MD = 4.45, 95%CI 1.47 to 7.43).

    “The BBS and SF-36 physical function score were significantly better in the training group (MD = 4.45, 95%CI 1.47 to 7.43, Z = 2.93, P = 0.003)”
