I’m Nicole, a PhD researcher in Biomechanics at UniSQ, studying exercise-induced muscle damage, repeated bout effects, and neuromuscular adaptations to eccentric exercise. My work explores how muscles adapt, recover, and build resilience, with applications in sports science and rehabilitation. Looking forward to connecting with researchers in biomechanics and exercise science!

💊 A recent study on L-Citrulline supplementation found that an 8g dose did not significantly enhance resistance exercise performance, muscle oxygenation, or subjective measures like effort and muscle pump compared to a placebo in trained men and women.

-While the study only examined acute effects, it suggests that L-Citrulline may not be effective for boosting performance or muscle pumps.

🚴‍♂️ A study on identical twins exercising 2 hours daily for 93 days (burning 1000 calories/day) showed an average weight loss of 11 pounds, all from fat mass.

-Despite identical diets and exercise, weight loss varied among twins, highlighting individual variability in response to calorie deficits and exercise.

🔍💪 Boost Your Lifts with Beetroot?

-A systematic review and meta-analysis delved into dietary nitrate supplementation, commonly found in beetroot shots, revealing a small but noteworthy improvement in muscular endurance, power, and velocity for exercises like back squats and bench presses.

-While promising, these findings call for more research to truly understand the benefits.

🏋️‍♂️🔬 Breaking Down Myostatin & Exercise.

-A fascinating study sheds light on myostatin's role in muscle hypertrophy. Whether lifting heavy (80% 1-RM) or light (30% 1-RM) weights to failure, the decrease in myostatin was similar.

-The takeaway? Muscle gene expression is uniform, debunking that heavier weight used in workouts is a differentiator for anabolic responses.

Steroids have been used by Hollywood actors who want to get buff for decades — since the 1970s, when the action hero archetype emerged with movies like "Rocky" and "The Incredible Hulk" TV show. Consequence discusses whether these drugs are really being used by pretty much everyone in Hollywood, and if it even matters.

Fun muscle facts I've learned:

• Nearly every muscle fiber runs the whole length of the muscle. Muscle fiber == muscle cell. So my bicep is made up of ~1mil muscle cells all of them ~9″ long.

• Muscle cells have multiple nuclei— in fact they have 100s, some even 1000s. Cellular protein synthesis requires a nucleus, and muscles do that all the time. With how long they are, they need *lots* of nuclei as infrastructure for protein synthesis.

Can a #science person of mastodon explain why I am suddenly enjoying running now for the first time in my life? I've been doing very little cardio and an immense amount of heavy strength training (with progressive overload) in the last few months, but I did sprints yesterday and enjoyed them so much. I felt like I could go on forever, and I even am going for a run later today too.

I used to do crosscountry running in high school but hated it and felt miserable, and had pain at times. I constantly felt like I was out of breath even though at that point I was running at least a mile or two every day. Did strength training really help me that much versus doing more cardio (like I was doing in high school)?

Exercise research is fraught with issues, esp controlling multiple variables. Meta-analyses have limited value because of that. Recent peeve: HIIT research. e.g. Study comparing 30s hi-intensity intervals/120s recovery with 60s/60s (which, of course= better outcome). Ergo, 120s recovery (regardless of hi-int intervals)= useless. Why not compare 30s/60s? Or 60s/120s? Why change two variables instead of one? Try ratios? #exercisescience #exercise
