Comparison of two resistance training protocols, 6RM versus 12RM, to increase the 1RM in healthy young adults. A single-blind, randomized controlled trial.

Purpose: The purpose of the study is to compare the effect in healthy young adults of two resistance training protocols, six-repetition maximum (RM) versus 12RM on maximum strength (1RM).

Method: A single-blind, randomized controlled trial was used in the study. Sixty-two healthy physical therapy students, with age (mean [+standard deviation]) 23 (+2.

Effects of low-level laser therapy and eccentric exercises in the treatment of recreational athletes with chronic achilles tendinopathy.

Background: Eccentric exercises (EEs) are recommended for the treatment of Achilles tendinopathy, but the clinical effect from EE has a slow onset.

Hypothesis: The addition of low-level laser therapy (LLLT) to EE may cause more rapid clinical improvement.

Study Design: Randomized controlled trial; Level of evidence, 1.

Is mechanical pain threshold after transcutaneous electrical nerve stimulation (TENS) increased locally and unilaterally? A randomized placebo-controlled trial in healthy subjects.

Background And Purpose: It is not fully understood how transcutaneous electrical nerve stimulation (TENS) intensity affects mechanical pain threshold.

Method: Sixty-six healthy volunteers (13 male, 53 female; 132 hands) without prior experience of TENS participated in the study, which comprised a randomized single-blind controlled trial. TENS was administered for 20 minutes through electrodes (25 x 25 mm) placed on the hands and forearms with a fixed frequency of 100 Hz and pulse duration of 150 micros.
