Equilibrium and postural stability are maximized when gravity's line falls centrally within a wide base of support and this point is kept low
What is the Center of Gravity (COG)?
Research in healthy women demonstrated that training under direct personal trainer supervision resulted in significantly higher self-selected levels of this variable
What is Self-Selected Training Intensity / 1RM Percentage?
Long-term periodization cycles are divided into three primary phases: Preparation, Competitive, and this recovery-focused phase
What is the Transition Phase?
The three pillars of safety in strength and conditioning encompass environmental/facility, communicative/behavioral, and this technical pillar
What is Biomechanical & Technical Safety?
In weightlifting research, the presence of this individual during heavy sets significantly elevated both athlete performance and psychological confidence
What is a Spotter?
A 5 to 10 minute low-intensity walking or cycling cooldown assists cardiovascular recovery and accelerates removal of this metabolic byproduct
What is Lactate / Metabolic Waste?
Ground reaction forces exerted during sprinting or jumping directly illustrate this fundamental physical law formulated by Isaac Newton
What is Newton's Third Law (Action and Reaction)?
Research on post-workout recovery examined whether foam rolling reduces delayed-onset muscle soreness (DOMS) or primarily alters this perceptual threshold
What is Pain / Discomfort Tolerance?
When designing programs specifically for maximal strength or explosive power development, rest intervals between sets should fall within this duration
What is 2 to 5 minutes?
A proper lower-body squat progression moves from bodyweight/goblet squats to back squats, followed by this demanding single-leg movement
What is the Bulgarian Split Squat (Unilateral Squat)?
Progressive program design transitions clients from bilateral compound movements toward these sport-specific single-leg or single-arm exercises
What are Unilateral Movements?
Supervised resistance training demonstrates clinical superiority over unsupervised training in these three key outcomes
What are higher rates of progression, better technique / fewer injuries, and higher self-selected intensities?
