Thoughts/Quotes
 

• Your movement signature is not strength. It’s your ability to put meaning and action to your perception as quick as possible – Harjiv Singh

 

• Don’t go into innovation & entrepreneurship if you don’t have an extremely high tolerance for humiliation. Tons of people, even potential customers, will mock you until you get it right…the entrepreneurial journey to success is long & difficult – Alex Osterwalder

 

• What I fail to comprehend is Y everyone is so darn sure that fatigue causes ACL injuries... or any other injuries... is this taught in the standard curriculums? – Tim Hewett

 

• You have to know the rule before you can break the rules

 

• My complaint with Physical Therapy is they label you, describe your condition, give you restrictions, give you generic exercises/modalities, and tend to put people on a reductionist solution path.

 

• It’s better to be strong with some asymmetries than have no asymmetries and be weak

 

• We can make athletes learn better by performing worse – pull into dysfunction/error can highlight the athletes awareness of problem

 

• Return to play should emphasize the whole athlete NOT just the physical

 

• Many coaches still believe that the only/best way to train force absorption is the catch portion of Olympic lifts.

 

• Perceptual information and movement are interlinked; training should reflect specific information-movement couplings.

 

• All things being equal – best posture wins – Vince Anderson

 

• Try accelerating the whole race – Vince Anderson

 

• Generally, the athlete moving fastest at 50m will beat the athlete that reaches 50m first – Stuart McMillian

• 5 × 4 jump squats at 40% 1RM with 3 minutes rest shown to potentiate performance (CMJ, RSI & RFD) 24-48 hours after session.

• Decision-making behaviour is best considered at the level of the performer–environment relationship and viewed as emerging from the interactions of individuals with environmental constraints over time towards specific functional goals.

 
Bruce, L., Farrow, D., Raynor, A., & Mann, D. (2012). But I can’t pass that far! The influence of motor skill on decision making. Psychology of Sport and Exercise, 13(2), 152-161.
 

• Motor skill influenced the performance of the required action, but not necessarily the decision made. Performance is superior on a coupled perceptual-motor task relative to a de-coupled perceptual-cognitive task. Motor skill performance was commensurate with expertise.

 
Liefeith, A., Kiely, J., Collins, D., & Richards, J. (2018). Back to the Future–in support of a renewed emphasis on generic agility training within sports-specific developmental pathways.Journal of sports sciences, 1-6.
 

• The authors propose that generic agility can play a role in operationalising movement development through facilitating skill transfer: thereby enabling the learning of new skills, reduce incidence of injury and facilitating re-learning of old skills during rehabilitation and Return-to-Play processes.

• Although there is a large body of cross-sectional literature providing a rationale for resistance exercise for sport, its implementation is largely based on the following: 1) An increase in muscle size will produce an increase in strength and 2) a stronger muscle will increase sports performance. However, there is a lack of evidence to support these assumptions. The weight of evidence suggests that resistance exercise may indirectly impact sports performance through injury prevention, as opposed to directly improving sport related abilities.

• It can be argued that what is crucial is not speed and agility, but how the capacities are exploited in the game. Speed and agility will be ineffective unless they can be combined with the ability to employ these capacities to effectively perform the tasks of the game. Optimizing these capacities requires a sophisticated development program that addresses the full gamut of potential constraints to performance. This article outlines how such a development program has been set-up at an English premier league soccer academy.

• The purpose of this study was to determine which of 3 forms of recovery were the most effective after an inning of pitching in baseball. Three different measurements were used to determine which recovery method was most effective; the difference in blood lactate (BLa) levels was used as a biological measurement, average pitching speed was the physiological measurement, and the psychological measurement was done on how the pitchers perceived their pitching and recovery. The recovery methods that were used were passive recovery (PR), active recovery (AR), and electromuscular stimulation (EMS). Seven college men aged 21 (62 years) who were National Collegiate Athletic Association Division II college baseball pitchers were assessed during game play simulations. Blood lactate levels decreased significantly from the premeasurement to the postmeasurement with the EMS recovery method (p , 0.0005); however, BLa did not change for PR (p = 0.017) or AR (p = 0.134). Perceived recovery was also found to be best in the EMS and PR conditions. These findings suggest that EMS is an effective recovery method between innings of pitching

• Previous investigations of strength have only focused on biomechanical or psychological determinants, while ignoring the potential interplay and relative contributions of these variables. The purpose of this study was to investigate the relative contributions of biomechanical, anthropometric, and psychological variables to the prediction of maximum parallel barbell back squat strength. Twenty-one college-aged participants (male = 14; female = 7; age = 23 ± 3 years) reported to the laboratory for two visits. The first visit consisted of anthropometric, psychometric, and parallel barbell back squat one-repetition maximum (1RM) testing. On the second visit, participants performed isometric dynamometry testing for the knee, hip, and spinal extensors in a sticking point position-specific manner. Multiple linear regression and correlations were used to investigate the combined and individual relationships between biomechanical, anthropometric, and psychological variables and squat 1RM. Multiple regression revealed only one statistically predictive determinant: fat free mass normalized to height (standardized estimate ± SE = 0.6 ± 0.3; t(16) = 2.28; p = 0.037). Correlation coefficients for individual variables and squat 1RM ranged from r = -0.79-0.83, with biomechanical, anthropometric, experiential, and sex predictors showing the strongest relationships, and psychological variables displaying the weakest relationships. These data suggest that back squat strength in a heterogeneous population is multifactorial and more related to physical rather than psychological variables.

• There was a stage of temporal slower development of sprinting ability from age 8.8 to 12.1 years, being characterized by unchanged propulsive force and decreased step frequency. Moreover, increasing propulsive forces during the middle acceleration and maximal speed phases and during the initial acceleration phase are probably responsible for the rapid development of sprinting ability before and after the period of temporal slower development of sprinting ability.

• Individual differences in 100-m-race performance cannot be explained by the muscularity of specific muscles, and 23% of the variability in the performance can be explained by the relative difference between the muscularity of gluteus maximus and quadriceps femoris; faster runners have a greater gluteus maximus relative to quadriceps femoris.
