Posts highlight specific points from the article, such as the effectiveness of squats for muscle development, exemplified by comments about exercise execution and safety considerations; the tone blends acknowledgment of research with practical exercise insights, indicating moderate engagement and interest.

AgreementModerate agreement

Most discussions recognize the findings, with some confirming the study's insights about exercise effectiveness.

InterestModerate interest

Posters show moderate curiosity, referencing sources and discussing exercise details rather than expressing strong passion.

EngagementModerate engagement

Comments involve personal opinions and practical implications, indicating thoughtful but not deeply involved interactions.

ImpactNeutral impact

The conversations suggest some influence on exercise choices, but no strong consensus on groundbreaking implications.

Abstract in brief

  • The study found that different technique variations, such as foot stance and angles, did not significantly affect muscle activity or knee forces during squats and leg presses, but squats generally produced higher forces and muscle activation compared to the leg press types.
  • Squats resulted in greater quadriceps, hamstrings, and overall knee forces, especially during the extension phase, making them potentially more effective for muscle development but also riskier for individuals with knee disorders, particularly at deeper flexion angles.
  • Although no ACL forces were observed across exercises, variations in knee forces and muscle activity depending on stance and phase suggest that training within certain knee flexion ranges could be optimized to balance effectiveness and knee safety.

@CoachBodaciouz @TheJoeySwoll This journal article alone shows what I already said: it’s not as good at hamstring activity as other exercises, but high and wide on the press does work & can help develop hamstring muscle. https://t.co/5LDhBqR1F0
