A 2026 meta-analysis of 21 intervention studies and a rugby league pressure-training trial explain why the gap between training and competition opens, and which interventions have closed it.

A meta-regression of 122 interventions and 44,747 people, and a meta-analysis of 28 tracker trials, explain why a paper log or an app makes training stick, and what a log needs to contain to drive progression.

A 2025 review of 27 studies on superstition in sport and a map of 73 sport-psychology meta-analyses explain why rituals exist, who has them, and why the anxiety they manage is not the variable that decides results.

Two meta-analyses of 85 studies measure the link between belief and competitive performance, where it is strongest, where it nearly vanishes, and why calibrated belief beats maximal belief.

Two meta-analyses across 67 studies put a number on the link between stress outside sport and injury inside it - small, real, largest in adolescents and non-elite athletes, and trainable.

The largest synthesis ever assembled on exercise and cognition, plus an umbrella review that grades the older-adult evidence, put numbers and honest certainty on the claim that training helps thinking.

The longest study of adult life ever run says relationships predict who ages well. A 2023 meta-analysis of 90 cohorts and 2.2 million people tests the claim: social isolation carried about a third more mortality risk, loneliness about a seventh.

Too flat and you underperform; too wired and you fall apart. The inverted-U hypothesis is the oldest idea in sport psychology, and a 2025 analysis of 320,000 elite shooting scores shows it still holds, with important caveats about who and what sport.

Stress is not the enemy of performance; unmanaged stress is. A 2026 network meta-analysis of 46 trials and a systematic review of 64 intervention studies show which techniques hold up, and which promises to be wary of.

Concentration in competition is a trainable skill, not a personality trait. Two lines of research, mindfulness training and quiet eye training, show what actually moves the needle and how long it takes.

Coach support is one of the strongest predictors of whether a young athlete enjoys sport and keeps playing. What the meta-analyses show about autonomy-supportive versus controlling coaching, and what to do when the relationship goes wrong.

Habit science says one specific, context-tied eating goal every couple of weeks becomes automatic fast. A three-year trial says tiny changes alone do not prevent weight gain. Both are true, and the combination is the method.

Quantitative research finds patterns across many athletes; qualitative research finds what is going on inside one. What each can and cannot claim, how each is judged, and why a coach should read both.

Choking has two known mechanisms, and the interventions that work target them directly. What the systematic review and meta-analysis say about routines, quiet eye, pressure training and the ones that do nothing.

Mental fatigue before an event is real and measurable. Here is what the trials say counters it, from caffeine and music to mindfulness and a coach who does not micromanage.

A meta-analysis of perceptual-cognitive expertise and a meta-analysis of deliberate practice show what experts do differently with their eyes and attention, and how much of the gap practice alone explains.

A systematic review of kinesiophobia in injured athletes and a sports-medicine perspective on fear of movement show why tentative play happens and what parents and coaches can do that actually helps.

The founding experiment on the peak-end rule for pleasant experiences and a 2023 resistance-training trial show that memory keeps the peak and the ending, and that ordering a session accordingly changes how people feel about it.

Only three of nine studies in a systematic review of elite team athletes actually measured whether flow relates to performance, and some research found peak performance achievable without it. Mindfulness interventions did reliably increase flow while reducing anxiety. What is actually established, and what is still just an appealing story.

Across 86 randomised trials and 3,593 athletes, imagery practice improved performance with an effect size of 0.5 - and imagery combined with other psychological skills beat imagery alone by a wide margin. It even builds measurable strength without moving, though less than actually lifting. What the optimal dose looks like.
