Objectives: To examine the effects of a time-saving leg-press training program with moderate vibration on strength parameters, pain, and functional outcomes of patients after total knee arthroplasty (TKA) in comparison with functional physiotherapy.
Design: Randomized controlled trial.
Setting: Outpatient rehabilitation department at a university teaching hospital.
Participants: Patients (N=55) with TKA were randomly allocated into 2 rehabilitation groups.
Interventions: Six weeks after TKA, participants either underwent isokinetic leg-press training combined with moderate vibration (n=26) of 15 minutes per session or functional physiotherapy (n=29) of 30 minutes per session. Both groups received therapy twice a week for a period of 6 weeks. Participants were evaluated at baseline (6wk after TKA) and after the 6-week rehabilitation program.
Main Outcome Measures: The main outcome measure was maximal voluntary contraction (MVC) of the involved leg. Secondary outcome measures were pain assessed with a visual analog scale (VAS), range of motion, stair test, timed Up and Go test, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC).
Results: Both groups showed statistically significant improvements in MVC of knee extensors measured on the knee dynamometer (leg-press group: from 0.8±.06 to 1±.09Nm/kg body weight [BW], physiotherapy group: from 0.7±.06 to 0.9±.06Nm/kg BW; P<.05) and in closed kinetic chain on the leg press (leg-press group: from 8.9±.77 to 10.3±1.06N/kg BW, physiotherapy group: from 6.7±.54 to 9.1±.70N/kg BW; P<.05) and in pain at rest (leg-press group: from 2±.36 to 1.3±.36 on the VAS, physiotherapy group: from 1.2±.28 to 1.1±.31; P<.05), WOMAC scores, and functional measurements after 6 weeks of training. There was no significant difference between the 2 groups concerning strength, pain, and functional outcomes after training (P>.05).
Conclusions: Isokinetic leg-press training with moderate vibration and functional physiotherapy are both effective in regaining muscle strength and function after TKA; however, isokinetic leg-press training is considerably less time consuming.

Background: The essential amino acid leucine (LEU) plays a crucial role in promoting resistance-training adaptations. Dileucine (DILEU), a LEU-LEU dipeptide, increases MPS rates, however its impact on resistance training outcomes remains unexplored. This study assessed the effects of DILEU supplementation on resistance training adaptations.

Unlabelled: Although exercise is medicine for outpatients with schizophrenia, it is unclear if one-year adherence-supported exercise leads to a "tipping point", at which the exercise becomes a routine manifested as life-long training in the patient group.
Methods: Forty-eight outpatients (28 men/20 women: 35 ± 11 (mean ± SD) years) with schizophrenia (ICD-10: F20-29) were randomised to: 1) collaborative care group (TG), performing aerobic interval (AIT; 4 × 4-min treadmill walking/running at ∼90 % peak heart rate) and leg press maximal strength training (MST; 4 × 4 repetitions at ∼90 % maximal strength [1RM]) 2d·wk. for 1-year, supported by transportation and training supervision; or 2) control group (CG).

Unlabelled: This study examines how power training affects estimated bone strength, revealing that females benefit more than males, especially in the upper limbs (radius). These findings highlight the importance of designing sex-specific exercise programs to enhance bone health. Further research is needed to optimize training duration and address site-specific differences.

Background: Muscle mass and strength are severely compromised in patients diagnosed with multiple myeloma, such that the risk of poor overall survival increases as the prevalence of low muscle mass, also known as sarcopenia, increases. Additionally, at the time of autologous stem cell transplant (ASCT), 51% of patients experience low muscle mass and strength, which can prolong hospitalization and lead to increased risk of obesity, insulin resistance, lowered physical function, and poor quality of life.
Objective: The PROTECT (Prehabilitation Exercise Training in Multiple Myeloma Patients Undergoing Autologous Stem Cell Transplantation) trial will examine the preliminary effects of digitally supervised prehabilitative aerobic and resistance exercise on muscle strength in patients with multiple myeloma scheduled for ASCT.
