Clinical Sports Physiologist and Rehabilitation Specialist holding a PhD in Kinesiology. She focuses on injury prevention, metabolic health, and science-backed recovery protocols for endurance athletes and aging adults.
Dr. Sarah Jenkins is a Clinical Sports Physiologist dedicated to demystifying the biology of human performance. With a PhD in Kinesiology and extensive clinical experience working with both elite swimmers and geriatric patients, she provides evidence-based advice on training mechanics and recovery. Sarah explains complex physiological concepts, such as the "anabolic window," heart rate variability (HRV), and the metabolic differences between HIIT and Zone 2 training, making them accessible to everyday athletes. She is particularly expert in aquatic therapy, detailing how swimming can rehabilitate joint injuries versus when breaststroke might exacerbate back pain. Her work also covers the crucial link between sleep stages and tissue repair, as well as the necessity of heavy lifting for bone density after age 50. Sarah challenges fitness fads with medical facts, offering safe, low-impact cardio alternatives and mobility drills that prevent the loss of coordination in later life. Her goal is to help readers build a body that remains functional and pain-free for decades.
