What the Evidence Shows

General Health and Mortality

• The 2018 US physical activity guidelines recognised that any bouts of physical activity count for health [1].
• Randomised controlled trials have failed to provide conclusive evidence that physical activity causes a reduced risk of death [13].
• Exercise therapy was not associated with an increased risk of non-serious adverse events (risk ratio 0.96) and appeared to reduce the risk of serious adverse events such as hospitalisation and pneumonia (risk ratio 0.62) in people with multimorbidity [62].
• Physical activity was associated with a decreased risk of all-cause dementia (pooled relative risk 0.80, 95% CI 0.77 to 0.84), Alzheimer’s disease (0.86, 95% CI 0.80 to 0.93) and vascular dementia (0.79, 95% CI 0.66 to 0.95) [75].
• Compared with obesity-low physical activity, there was no survival benefit of being normal weight if physical activity levels were low [55].

Dose, Intensity, and Specific Modalities

• Light-intensity physical activity accounts for the majority of physical activity energy expenditure (51–59%) [10].
• There may be no minimal or maximal threshold for the benefits of accelerometer-measured intensity-specific physical activity in relation to incident type 2 diabetes [18].
• Approximately 65 min per day of walking and 5 min of stair climbing were each linked to a more favourable cardiometabolic profile, while the adverse effects of sitting became pronounced above 12 hours per day [37].
• The modest volume of the prospective epidemiological evidence base and the moderate consistency between observational and laboratory evidence inhibits definitive conclusions regarding the association of light-intensity physical activity with adult cardiometabolic health and mortality [74].

Joint-Specific Outcomes and Interventions

• Protocols using painful exercises offer a small but significant benefit over pain-free exercises in the short term for the management of chronic musculoskeletal pain, with moderate quality of evidence [33].
• Exercise therapy is effective for some adolescents with patellofemoral pain but not all, and adherence to exercises is a challenge, with those doing home exercises three times per week or more being four times more likely to be recovered after 12 months [59].
• Exercise interventions implemented at ≤12 weeks after total knee arthroplasty primarily improved functional performance, whereas those lasting >12 weeks resulted in greater gains in muscle strength and joint flexibility [22].
• Future research should focus on optimizing current exercise regimens for people with knee osteoarthritis and exploring how to improve adherence while minimizing symptom exacerbation by other exercise modalities [65].

Injury Prevention and Rehabilitation

• Maintenance interventions may help people continue to be physically active and improve physical function and health-related quality of life following exercise therapy for chronic conditions [6].
• There is moderate certainty evidence that fall prevention exercise programmes are likely to be cost-effective [23].
• A coaching intervention to enhance physical activity and prevent falls in community-dwelling people aged 60+ years improved daily steps, moderate-to-vigorous physical activity, hours per week of walking, overall well-being, quality of life and disability [31].
• To realise the greatest effects in reducing musculoskeletal injury and concussion risk in schoolboy rugby players, players should complete a pre-activity movement control exercise programme at least three times per week [63].
• More adequately powered and rigorous trials are needed to evaluate the effect of exercise interventions on sport-related concussion incidence, and on linear and rotational head accelerations [66].
• Physical activity interventions that combine self-monitoring with other components provide an additional modest yet sustained increase in step count compared with self-monitoring alone [60].

Implementation, Adherence, and Cost-Effectiveness

• Brief advice in primary care is a cost-effective way to improve physical activity among adults, provided short-term mental health gains are considered [35].
• Despite scientific evidence, many coaches are unaware of the benefits of exercise-training programmes and do not deliver them, leading to low compliance and limited success in injury prevention [32].
• Suggestions from community football players about potential improvements to training programmes included reducing duration, increasing range of drills/exercises and promoting its injury prevention and other benefits to players [16].
• At follow-up, 65.0% of inactive participants in a Workplace Challenge were taking part in sport and 85.6% were meeting recommended moderate-to-vigorous physical activity guidelines [39].
• A school-based intervention to prevent decline in adolescent physical activity levels resulted in a significant group-by-time interaction for mean minutes of moderate-to-vigorous physical activity per day in favour of the intervention group (adjusted difference between groups at follow-up=3.85 min, 95% CI (0.79 to 6.91), p≤0.01), including significantly more vigorous physical activity (2.45 min, p≤0.01), equating to 27 min more moderate-to-vigorous physical activity per week [53].
• There was no significant effect of an augmented exercise referral scheme using web-based behavioural support on weekly moderate-to-vigorous physical activity at 12 months between the groups recorded in ≥10 min bouts (mean difference 11.8 min of moderate-to-vigorous physical activity, 95% CI: −2.1 to 26.0; p=0.10) or without bouts (mean difference 13.7 min of moderate-to-vigorous physical activity, 95% CI: −26.8 to 54.2; p=0.51) [54].
• Treatment groups in the WALK 2.0 randomised controlled trial differed significantly in trajectories of minutes/day of physical activity (p=0.0198), through a greater change at 3 months for Web 2.0 than Web 1.0 (7.3 min/day, 95% CI 2.4 to 12.3) [58].
• Teachers at intervention schools recorded a greater increase in weekly minutes of physical activity implemented than teachers assigned to the control schools by approximately 44.2 min (95% CI 32.8 to 55.7) from baseline to 12-month follow-up [61].
• Results from a formal 2-year cluster randomised-controlled trial confirmed that the Youth-Physical Activity Towards Health programme was effective in improving youth fundamental movement skills proficiency [56].
• At 18 months, there were intervention effects on children’s weekday sedentary behaviour (−27 min) for the physical activity intervention, and on children’s average day physical activity (5.5 min) for the sedentary behaviour intervention [67].
• Exercise is associated with improvements in physical and mental health in the maintenance of weight loss [64].

Methodology and Research Gaps

• Researchers need to come to agreement about how to collectively define physical activity, sedentary behaviour and sleep through an inclusive and systematic consensus process to prevent a looming ‘24-hour Babel’ [15].
• The consensus statement on precision exercise medicine outlines approaches that may identify determinants and modifiers of cardiorespiratory fitness exercise response and recommends future research to better understand exercise response variability [21].
• Much of the evidence presented in the Copenhagen Consensus statement 2019 on physical activity and ageing is based on longitudinal associations from observational and randomised controlled intervention studies, as well as quantitative and qualitative social studies in relatively healthy community-dwelling older adults [14].
• The joint association between daily time spent in physical activity, sedentary behaviour and sleep and all-cause mortality was examined using compositional analysis in a pooled analysis of six prospective cohorts [25].
• Because of the absence of a control group, findings on the effectiveness of proximal interphalangeal joint orthosis and therapeutic exercise in the management of trigger finger demonstrate feasibility and short-term clinical improvement but cannot establish superiority over other conservative treatments [34].
• Findings from a clinical study of traditional Chinese medicine comprehensive therapy for exercise-related musculoskeletal injuries suggest potential benefits of this treatment approach, though randomised controlled trials are needed for definitive efficacy assessment [36].
• The Prisma in Exercise, Rehabilitation, Sport medicine and SporTs science (PERSiST) guidance attempts to address the problem of poor reporting of medical and healthcare systematic reviews in the sports and exercise medicine, musculoskeletal rehabilitation, and sports science fields [70].

• [L1] There was a significant group-by-time interaction for mean minutes of MVPA per day in favour of the intervention group (adjusted difference between groups at follow-up=3.85 min, 95% CI (0.79 to 6.91), p≤0.01), including significantly more vigorous physical activity (2.45 min, p≤0.01), equating to 27 min more MVPA per week. [53] (10.1136/bjsports-2014-094523)
• [L1] There was no significant effect of the intervention on weekly MVPA at 12 months between the groups recorded in ≥10 min bouts (mean difference 11.8 min of MVPA, 95% CI: −2.1 to 26.0; p=0.10) or without bouts (mean difference 13.7 min of MVPA, 95% CI: −26.8 to 54.2; p=0.51). [54] (10.1136/bjsports-2020-103121)

• [Paper] Exercise therapy is effective for some adolescents but not all, and adherence to exercises is a challenge, with those doing home exercises three times per week or more being four times more likely to be recovered after 12 months. [59] (10.1136/bjsports-2016-096268)
• [L1] Physical activity interventions that combine self-monitoring with other components provide an additional modest yet sustained increase in step count compared with self-monitoring alone. [60] (10.1136/bjsports-2021-105198)
• [L1] Teachers at intervention schools recorded a greater increase in weekly minutes of PA implemented than teachers assigned to the control schools by approximately 44.2 min (95% CI 32.8 to 55.7) from baseline to 12-month follow-up. [61] (10.1136/bjsports-2020-103764)
• [L1] Exercise therapy was not associated with an increased risk of non-serious adverse events (risk ratio 0.96) and appeared to reduce the risk of serious adverse events such as hospitalisation and pneumonia (risk ratio 0.62). [62] (10.1136/bjsports-2021-104367)

• [L1] More adequately powered and rigorous trials are needed to evaluate the effect of exercise interventions on SRC incidence, and on linear and rotational head accelerations. [66] (10.1136/bjsports-2024-108260)
• [L1] At 18 months, there were intervention effects on children’s weekday SB (−27 min) for the PA intervention, and on children’s average day PA (5.5 min) for the SB intervention. [67] (10.1136/bjsports-2022-105825)
• [L3] Adhering to PA guidelines (150–300 min per week) and surpassing them (≥300 min per week) were associated with 23% and 37% lower risk of incident CVD, respectively, compared with those with the lowest PA duration (0–75 min per week). [68] (10.1136/bjsports-2024-108734)
