Trunk muscle activity may not play a major role in explaining lifting-related low back pain among manual workers, according to a 2025 study published in Musculoskeletal Science and Practice. The findings challenge a long-standing assumption in occupational health and rehabilitation that people with low back pain change the way
A 2018 study found that using standing posture assessments to find whether someone has low back pain to be “irreproducible.” The researchers of this study, led by Dr. Hendrik Schmidt from Charité–Universitätsmedizinin Berlin wrote that such lack of reproducible results can lead to misinterpretation of imaging measurements, wrong diagnoses and
Current research finds that you don’t need to lift heavy weights like the beefiest guy at the gym to get bigger muscles. A 2022 umbrella review of 14 meta-analyses reported that training volume and frequency may matter more than how heavy you lift. Volume When other variables are held constant,
Key takeaways Mechanical tension and mechanotransduction are currently the strongest evidence-based explanations for how muscles get bigger. Current evidence suggests that anabolic hormones, cell swelling (“pump”), and metabolites have little to no effect on muscle hypertrophy. A Canadian exercise scientist suggests a few ways for academics and others to disseminate
Although we still have a lot to learn about how muscles contract, we do understand the basics of how the nervous system initiates a series of actions that contract a muscle. What about muscle movements that we don’t consciously decide to make, like breathing, digestion, and heartbeats? And what about
Walk into any gym, and you’ll likely find a variety of balance equipment stacked on racks or strewn about the floor, like wobble boards, BOSU balls, and foam pads. But how effective is balance training for improving athletic performance and injury recovery? Let’s see what the research says. Strength and
Even as clinical guidelines discourage routine imaging for low back pain, many patients continue to ask for MRIs, X-rays, or CT scans. Not necessarily for diagnosis, but for something harder to measure: reassurance. A 2025 study published in BMC Primary Care suggests that imaging is less about medical necessity and
A 2025 editorial published in the British Journal of Sports Medicine argued that increasing muscular strength is not the main driver for reducing pain. Instead, they wrote that strength training is one component among several factors that contribute to pain reduction, based on the biopsychosocial framework of pain. These other
An inguinal hernia occurs when a weakness in the lower abdominal wall at the inguinal canal allows the contents of the abdomen to bulge through the rupture. “Hernia,” from the Latin for “rupture,” is used to describe several conditions in your body, and inguinal hernia is one of the most
A 2015 study published in Journal of Science and Medicine in Sport found that cricket fast bowlers with abdominal symmetry have higher incidences of low back pain than those who have abdominal muscle asymmetry. Sixteen of the 25 teenage cricket fast bowlers in South Africa participated in the study have
Lumbar epidural steroid injections (LESIs) remain a popular minimally invasive option to reduce nerve-root inflammation and buy time before—or instead of—surgery. A 2025 narrative review published in Cureus by Soin et al. synthesized the latest evidence on LESIs’ real-world performance from 2020 to 2025. The authors concluded that LESIs function
Pain is one of the most common reasons people seek health care, yet it remains widely misunderstood. In Tell Me Where It Hurts: The New Science of Pain and How to Heal, pain psychologist Rachel Zoffness translates modern pain science into accessible language. The result is not just an
