Response of Knee Extensor Muscle-Tendon Unit Stiffness to Unaccustomed and Repeated High-Volume Eccentric Exercise.

The purposes of this study were to investigate the muscle-tendon unit stiffness response and to compare the stiffness with those of other indirect markers induced by two bouts of unaccustomed eccentric exercise. Eleven untrained men performed two bouts of 200 maximal eccentric contractions of the right quadriceps 4 weeks apart. Changes in stiffness, pain evoked by stretching and pressure, plasma creatine kinase (CK) activity, and muscle thickness were followed for 7 days after each bout.

Effect of diaphragm and abdominal muscle training on pelvic floor strength and endurance: results of a prospective randomized trial.

Pelvic floor muscles (PFMs) play a crucial role in urinary continence. Therefore, training the PFMs remains the most popular conservative treatment for urinary incontinence (UI). The effect of training other body muscles on the PFMs is unclear and mostly hypothetical.

Dynamics of pelvic floor muscle functional parameters and their correlations with urinary incontinence in men after radical prostatectomy.

Aims: To evaluate the dynamics of pelvic floor muscle strength, endurance, and urinary incontinence in a 6-month period in men after radical prostatectomy and to determine correlations between pelvic floor muscle strength, endurance, and urinary incontinence.

Methods: Forty-two men with prostate cancer treated with radical prostatectomy participated in the study. Pelvic floor muscles parameters were evaluated using the anal perineometer.

[Impact of intensive and traditional rehabilitation on quadriceps strength after anterior cruciate ligament reconstructive surgery].

Unlabelled: After knee anterior cruciate ligament reconstructive surgery, the recovery of the former level of physical activity takes from 3 to 12 months. Such a wide range of recovery period of physical activity suggests that rehabilitation in most cases is not optimal. According to the majority of authors, after the surgery, a patient can resume intensive physical activity, when the difference in muscle strength between the operated lower extremity and another extremity is not greater than 10-15%.

Changes in height of jump, maximal voluntary contraction force and low-frequency fatigue after 100 intermittent or continuous jumps with maximal intensity.

Healthy untrained males (age 25.4 +/- 1.7 years, n=12) gave their informed consent to take part in all experiments within the study.
