Finding predictive factors of exercise adherence in randomized controlled trials on low back pain: an individual data re-analysis using machine learning techniques.

Objective: To identify predictors of adherence in supervised and self-administered exercise interventions for individuals with low back pain.

Design: Cohort study.

Setting: Rehabilitation.

Collagen Peptide Supplementation during Training Does Not Further Increase Connective Tissue Protein Synthesis Rates.

Introduction: Protein supplementation increases postexercise muscle protein synthesis rates and, as such, supports exercise-induced muscle conditioning. Collagen protein has been suggested as the preferred protein source to stimulate muscle connective protein synthesis rates during recovery from exercise. Here we assessed the effects of hydrolyzed collagen peptide supplementation on both myofibrillar as well as muscle connective protein synthesis rates during 1 wk of strenuous resistance exercise training.

A novel motorized office chair causes low-amplitude spinal movements and activates trunk muscles: A cross-over trial.

Introduction: Inactivity and long periods of sitting are common in our society, even though they pose a health risk. Dynamic sitting is recommended to reduce this risk. The purpose of this study was to investigate the effect of continuous passive motion (CPM) conducted by a novel motorized office chair on lumbar lordosis and trunk muscle activation, oxygen uptake and attentional control.

Metabolic power in the men's European handball championship 2020.

Purpose: To ascertain the typical metabolic power characteristics of elite handball players of different positions, and whether changes occur within matches.

Methods: 414 elite male handball players were included. During all 65 matches of the EURO 2020, local positioning system data were collected, yielding 1853 datasets.

The mechanical loading of the spine in physical activities.

Purpose: To summarize the mechanical loading of the spine in different activities of daily living and sports.

Methods: Since the direct measurement is not feasible in sports activities, a mathematical model was applied to quantify spinal loading of more than 600 physical tasks in more than 200 athletes from several sports disciplines. The outcome is compression and torque (normalized to body weight/mass) at L4/L5.
