Systematic review and meta-analysis of protein intake to support muscle mass and function in healthy adults

This systematic review and meta-analysis investigated if increased daily protein intake improves lean body mass (LBM), muscle strength, and physical function in healthy adults. It found that additional protein, particularly with resistance exercise, leads to small extra gains in LBM and lower body strength for younger adults at higher protein intakes (≥1.6 g/kg/day). However, effects on bench press strength, handgrip strength, and physical function were mostly trivial or unclear, with low certainty of evidence due to high heterogeneity and risk of bias in the included studies.

Twelve Weeks of Sprint Interval Training Improves Indices of Cardiometabolic Health Similar to Traditional Endurance Training despite a Five-Fold Lower Exercise Volume and Time Commitment

This study found that a very short, intense exercise routine (sprint interval training, SIT), requiring only 1 minute of intense exercise within a 10-minute session, improved markers of heart health and insulin sensitivity in sedentary men as much as traditional longer, moderate exercise (50 minutes). However, the human sample sizes were quite small (SIT n=9, MICT n=10, Control n=6), limiting how broadly these findings can be applied.

Effects of a daily, home-based, 5-minute eccentric exercise program on physical fitness, body composition, and health in sedentary individuals

This study found that a daily 5-minute eccentric exercise routine over 4 weeks improved some markers of physical fitness and mental health in sedentary individuals. However, the study lacked a true control group, and some of the positive changes (like S&R) did not meet all the pre-defined statistical criteria.

Differentiating C8-T1 Radiculopathy from Ulnar Neuropathy: A Survey of 24 Spine Surgeons

In a small survey of 24 spine surgeons attending a cervical spine course, many could not differentiate between C8-T1 radiculopathies (neck nerve issues) and ulnar neuropathy (elbow nerve issues) based on sensory and motor function. Only 63% correctly identified the sensory distribution of the ulnar nerve, and none could identify all the hand muscles controlled by C8-T1 without also naming incorrect ones.

The effect of eccentric phase duration on maximal strength, muscle hypertrophy and countermovement jump height: A systematic review and meta-analysis

This meta-analysis investigated the effects of eccentric phase duration on strength, muscle growth, and jump height. Shorter eccentric phases led to greater improvements in jump height, while longer phases may be better for strength gains in trained individuals or when volume-load is matched. Results for muscle growth were inconclusive, highlighting the need for further research.

The Effects of Creatine Monohydrate Supplementation on Recovery from Eccentric Exercise-Induced Muscle Damage: A Double-Blind, Randomized, Placebo-Controlled Trial Considering Sex and Age Differences

This study found that creatine supplements may improve muscle recovery after intense exercise, showing better strength recovery and less soreness compared to a placebo. The effect on reducing swelling was particularly notable in women. However, individual responses varied, and factors like diet and hormones weren't strictly controlled, potentially affecting the results.

Female Athletes With Better Psychological Readiness Are at Higher Risk for Second ACL Injury After Primary ACL Reconstruction

In a small study of female athletes, those who felt psychologically ready to return to sport after ACL reconstruction, particularly those with high risk appraisal scores, had a higher risk of a second ACL injury within two years. However, all athletes in the re-injury group had hamstring tendon autografts, potentially impacting the results.

International Olympic Committee Consensus Statement Methods for Recording and Reporting of Epidemiological Data on Injury and Illness in Sports 2020 (Including the STROBE Extension for Sports Injury and Illness Surveillance (STROBE-SIIS))

This consensus statement presents standardized methods for recording and reporting epidemiological data on injury and illness in sports. The recommendations include definitions, data collection protocols, and a STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) checklist extension (STROBE-SIIS) to enhance consistency and comparability in sports injury and illness research.

High cholesterol induces apoptosis and autophagy through the ROS-activated AKT/FOXO1 pathway in tendon-derived stem cells

High cholesterol was found to induce both apoptosis (programmed cell death) and autophagy (cellular self-eating) in tendon-derived stem cells (TDSCs). This dual effect is mediated by reactive oxygen species (ROS) activating a specific cellular pathway involving AKT/FOXO1 signaling, suggesting a new mechanism for how high cholesterol can contribute to tendon problems.
