Miscellaneous: Systematic Review And Meta-Analysis Master List

This meta-analysis found that post-exercise heat and cold therapy can both reduce muscle soreness assessed within 24 hours after the exercise session, but only heat therapy (particularly the use of hot packs) reduced soreness assessed more than 24 hours post-exercise. However, it’s worth noting that there were not statistically significant differences between heat and cold therapy. Given that cold therapy may reduce muscle growth, and heat therapy is at least as effective for reducing soreness, heat therapy may be a better option if you want to reduce soreness post-training.

The Validity and Reliability of Commercially Available Resistance Training Monitoring Devices: A Systematic Review. Weakley et al. (2021)

The current research examining the validity and reliability of commercial devices used for measuring velocity and power output in the gym is of fairly low quality overall, but it suggests that linear position transducers (the devices that have a string that attaches to the barbell; GymAware, SmartCoach, 1080Q, T-Force, Chronojump, Tendo, Virtuve, Fitronic, Open Barbell System, and Ergotest) generally perform better than the other types of devices on the market (accelerometers, mobile apps, and optic devices).

Effects of Bilateral and Unilateral Resistance Training on Horizontally Orientated Movement Performance: A Systematic Review and Meta-analysis. Moran et al. (2020)

Bilateral and unilateral training seem to have similar effects on gains in horizontal-oriented performance (sprinting, various agility tests, stair climb speed, etc.). Importantly, plyometric training seems to be key for maximizing horizontal performance. Plyometrics had the largest effect on horizontal performance during unilateral training, and combined training (plyometrics plus resistance training) had the largest effect during bilateral training.

Aging and Recovery After Resistance-Exercise-Induced Muscle Damage: Current Evidence and Implications for Future Research. Fernandes et al. (2020)

The key takeaway of this systematic review is that, by and large, older (~40-75 years old) and younger (<30 years old) don’t massively differ in their recovery responses following a resistance training session. However, it’s worth noting that a lot of the exercise protocols used in the research to this point have lacked ecological validity and, quite frankly, any significant degree of difficulty (for example, 6 sets of 5 eccentric reps at 40% of MVIC). If we use a “vote-counting” approach, older people seem to show signs of greater muscle damage and slower recovery (4 studies report that finding, 2 studies report greater damage or slower recovery in younger subjects, and the rest report no difference), and I personally suspect the current literature underestimates how large the differences would be with ecologically valid training protocols. However, the current evidence suggests that, at minimum, there’s not a completely night-and-day difference in recovery capacity between older and younger lifters.

Effects of Testosterone Supplementation on Sarcopenic Components in Middle-Aged and Elderly Men: A Systematic Review and Meta-Analysis. Parahiba et al. (2020)

I’m sure this comes as a surprise to no one, but exogenous testosterone supplementation tends to increase lean mass and strength.

The Impact of Sleep Duration on Performance Among Competitive Athletes: A Systematic Literature Review. Kirschen et al. (2020)

In general, sleep extension tends to improve athletic performance, while sleep restriction or deprivation tends to decrease performance. Those effects seem to be larger and more consistent for aspects of athletic performance that require focus or active thought (strategy, coordination, etc.) rather just sheer physiological capacity (strength, endurance, etc.). Additionally, longer-term interventions (lasting a few days or weeks rather than just one night) are more likely to find positive effects from sleep extension and negative effects from sleep restriction, including effects on physiological capacity.

This study was reviewed in more depth in the November 2020 issue of MASS.

Acute Effects of Cluster and Rest Redistribution Set Structures on Mechanical, Metabolic, and Perceptual Fatigue During and After Resistance Training: A Systematic Review and Meta-analysis. Jukic et al. (2020)

Cluster set training and rest redistribution training (which is basically the same thing as cluster set training) help people better-maintain velocity and power output during resistance training, while also reducing lactate accumulation and perceived effort.

Effects of Resistance Training on Muscle Size and Strength in Very Elderly Adults: A Systematic Review and Meta-Analysis of Randomized Controlled Trials. Grgic et al. (2020)

This meta was basically interested in investigating whether very old people (at least 75 years old) were still capable of getting stronger and building muscle. They are. The pooled effect size for strength was quite large (0.97), while the pooled effect size for hypertrophy was considerably smaller (0.30). The authors also report that resistance training didn’t cause a significant increase in grip strength, though I’d take that lack of significance with a grain of salt; the confidence interval barely crossed zero (ES = 0.25; 95% CI = -0.02-0.54; p = 0.064), and all point estimates leaned in favor of resistance training improving grip strength. They also report no significant fiber hypertrophy, though I’d also take that outcome with a grain of salt, since only 3 studies measured fiber hypertrophy (and again, all point estimates leaned in favor of resistance training).

Another recent meta by Straight and colleagues also examined fiber hypertrophy in older adults (age range: 59-88.5 years old). It found significant type I and type II fiber hypertrophy in older adults, with rates of hypertrophy tending to be lower for older subjects. However, age only explained a small proportion of the variance (~11%), suggesting that new lifters should still be able to experience some degree of hypertrophy into their 80s (though people in the 50s and 60s will generally experience more hypertrophy).

The Muscle Carnosine Response to Beta-Alanine Supplementation: A Systematic Review and Bayesian Individual and Aggregate Data E-Max Model and Meta-analysis. Rezende et al. (2020)

This was an interesting meta-analysis. It was interested in the maximum possible increase in muscle carnosine content following beta-alanine supplementation. The authors propose that muscle carnosine levels may be able to almost double following sufficient beta-alanine supplementation, but that most research protocols only provide enough beta-alanine supplementation to increase muscle carnosine levels by ~30%. They suggest that a cumulative dose of ~1500+g of beta-alanine would be required to maximize muscle carnosine levels. At the standard dose of 6.4g/day, it would, therefore, take approximately 8 months to maximize muscle carnosine levels, whereas lead-in times for many studies last only 4 weeks. If the authors’ model is accurate, the possible ergogenic effect of beta-alanine supplementation may be considerably larger than the current literature suggests, but studies with longer lead-in periods or larger daily beta-alanine doses would be required to confirm this hypothesis.

Does Acupuncture Benefit Delayed Onset Muscle Soreness after Strenuous Exercise? A Systematic Review and meta-analysis. Chunwei et al. (2020)

Acupuncture may improve recovery (soreness, isometric force, and creatine kinase) for up to 72 hours post-training. However, the majority of the studies included in this meta compared acupuncture to a no-treatment control condition, not a sham treatment. As such, it’s hard to know the degree to which these effects are driven by acupuncture itself, versus a simple placebo effect.

Core Muscle Activity during Physical Fitness Exercises: A Systematic Review. Olivia-Lozano and Muyor (2020)

This is a systematic review of 67 studies examining muscle activity in 6 different muscles, so it would be virtually impossible to succinctly summarize. However, if you’re interested in learning about how different exercises affect more muscle activation, this would be a useful review to read and mine for references.

A Meta-Analysis of the Effects of Foam Rolling on Performance and Recovery. Wiewelhove et al. (2019)

Foam rolling before exercise seems to have small beneficial effects on sprint performance and flexibility, but not jumping performance or strength. Foam rolling after exercise seems to have a small effect on attenuating acute post-training strength decreases, decreases in sprint speed, and muscle pain perception. The findings of another review were broadly similar.

Acute Effects of Foam Rolling on Range of Motion in Healthy Adults: A Systematic Review with Multilevel Meta-analysis. Wilke et al. (2019)

Foam rolling does acutely improve range of motion, but it doesn’t appear to be any more effective than stretching. Foam rolling may also be a bit more effective for females than males.

Cooling during exercise enhances performances, but the cooled body areas matter: A systematic review with meta‐analyses. Douzi et al. (2019)

Many different cooling interventions during exercise seem to improve aerobic exercise performance. There’s less research on anaerobic exercise, but whole-body cooling garments have some empirical support. This study was previously discussed in more depth in MASS.

Effects of Evening Exercise on Sleep in Healthy Participants: A Systematic Review and Meta-Analysis. Stutz et al. (2018)

On average, as long as you complete your exercise session at least an hour before going to bed, evening exercise shouldn’t have a significant negative impact on sleep.

Effects of local cryotherapy for recovery of delayed onset muscle soreness and strength following exercise-induced muscle damage: systematic review and meta-analysis. Nogueira et al. (2019)

Local cryotherapy (i.e. icing a muscle after you train it) does not seem to be effective for reducing soreness or attenuating strength losses following a training session.

Effects of Prior Cognitive Exertion on Physical Performance: A Systematic Review and Meta-analysis. Brown et al. (2019)

Intense mental exertion before exercise testing generally reduces most measures of physical performance. If possible, it’s probably not a bad idea to chill out and give your brain a break for a while before you work out.

Electromyographic activity in deadlift exercise and its variants. A systematic review. Martín-Fuentes et al. (2020)

This would be a tough review to summarize succinctly. However, it’s a good resource if you want to get a quick overview of the current EMG research on various deadlift varieties.

Including the Nordic hamstring exercise in injury prevention programmes halves the rate of hamstring injuries: a systematic review and meta-analysis of 8459 athletes. van Dyk et al. (2019)

The title of this meta-analysis is shockingly self-explanatory. Nordic curls dramatically decrease the risk of hamstrings strains in athletes.

Is tDCS an Adjunct Ergogenic Resource for Improving Muscular Strength and Endurance Performance? A Systematic Review. Machado et al. (2019)

Transcranial direct current stimulation (tDCS) seems to improve strength and strength endurance performance pretty reliably, but its effects on endurance performance are less reliable. More research is needed to understand how to most reliably elicit positive effects.

Overtraining in Resistance Exercise: An Exploratory Systematic Review and Methodological Appraisal of the Literature. Grandou et al. (2020)

While there’s a lot of research regarding markers and predictors of overtraining in aerobic sports, less total research exists regarding overtraining and resistance exercise. So far, the only reliable marker we know of for identifying overtraining in resistance exercise exercise is a sustained decrease in performance.

Physical Effects of Anabolic-androgenic Steroids in Healthy Exercising Adults: A Systematic Review and Meta-analysis. Andrews et al. (2018)

It should surprise no one to learn that anabolic steroids help people build more muscle and gain more strength. 13 studies reported adverse events, which are summarized below.

The association of resistance training with mortality: A systematic review and meta-analysis. Saeidifard et al. (2019)

Resistance training is associated with a ~20% lower rate of all-cause mortality. The combination of resistance and aerobic training is associated with a ~40% lower all-cause mortality rate. Breaking news: exercise is good.

The effect of exercise interventions on resting metabolic rate: A systematic review and meta-analysis. MacKenzie-Shalders et al. (2020)

Exercise interventions tend to increase your resting metabolic rate by ~70-100kcal/day, on average. The effect is statistically significant for resistance exercise but not aerobic exercise, primarily because the increase seems to be more homogeneous for resistance exercise (CI: 45 – 147kcal/day) than aerobic exercise (CI: -58 – 221kcal/day).

The Effect of the Menstrual Cycle and Oral Contraceptives on Acute Responses and Chronic Adaptations to Resistance Training: A Systematic Review of the Literature. Thompson et al. (2019)

It’s hard to give this systematic review a short summary. However, overall, oral contraceptives may have a slight negative impact on recovery from resistance exercise; their effect on resistance training adaptations is unclear. Female lifters may make slightly faster progress when training in the follicular phase of their menstrual cycle when compared to the luteal phase. It’s hard to make many firm conclusions, however, due to the variety of different oral contraception formulations and relative dearth of studies on the effects the menstrual cycle has on exercise recovery.

The Effects of Oral Contraceptives on Exercise Performance in Women: A Systematic Review and Meta-Analysis. Elliott-Sale et al. (2020)

This meta-analysis found that oral contraceptives may slightly reduce performance in female athletes. The pooled effect sizes were trivial (d = 0.18 when comparing the early follicular phase to the withdrawal phase on OCs, and d = 0.13 when comparing the rest of the menstrual cycle to active pill days on OCs), however. Therefore, oral contraceptives may slightly decrease exercise performance, but the magnitude of the effect is likely too small to be meaningful for most athletes, though the magnitude of the effect likely varies based on the individual and form of OC.

The Placebo and Nocebo effect on sports performance: A systematic review. Hurst et al. (2019)

Placebo and nocebo effects have small but notable effects on sport and exercise performance. The “intensity” of the placebo (i.e. something like placebo steroids are more intense than placebo caffeine supplementation) seems to substantially impact the magnitude of the placebo effect. This study was previously discussed in more depth in MASS.

An evidence-based approach for choosing post-exercise recovery techniques to reduce markers of muscle damage, soreness, fatigue and inflammation: a systematic review with meta-analysis. Dupuy et al. (2018)

Several different recovery modalities, including massage, active recovery, compression garments, water immersion, contrast water therapy, and cryotherapy were found to significantly decrease DOMS and attenuate increases in inflammatory markers. Massage was found to be most effective for attenuating both DOMS and perceived fatigue. It’s also worth noting that while cold water immersion was found to be effective for promoting recovery, other research shows that it can decrease muscle growth if used chronically. This study was reviewed in more detail in Volume 2, Issue 6 of MASS.

Talent Identification in Sport: A Systematic Review. Johnston et al. (2017)

We don’t actually know very much about talent identification in sport, generally. However, the quality of the research varies sport-to-sport. The research to-date is summarized in Table 1 of the article; there’s too much to provide a tidy synopsis here, but it’s worth reading for yourself if talent identification in a particular sport matters to you.

Blood flow restriction training in clinical musculoskeletal rehabilitation: a systematic review and meta-analysis. Hughes et al. (2017)

Low-load training with blood flow restriction seems to aid in strength recovery after injury better than low-load training without blood flow restriction. However, heavier training was more effective for regaining strength than low-load training with blood flow restriction. If loading is tolerated, heavier training is typically the better option; however, low-load training with blood flow restriction seems to be a better option than plain lo- load training in situations where a tissue isn’t yet ready for heavier loading.

Sleep Interventions Designed to Improve Athletic Performance and Recovery: A Systematic Review of Current Approaches. Bonnar et al. (2018)

Sleep extension (aiming for 9+ hours of sleep per night) was found to most reliably improve performance. Improving sleep hygiene also tended to improve performance, though to a smaller degree and less reliably than sleep extension. This systematic review was discussed in Volume 2, Issue 3 of MASS.

Choking interventions in sports: A systematic review. Gröpel and Mesagno (2018)

“The most reported effective interventions were pre-performance routines, quiet eye training, left-hand contractions, and acclimatisation training. The use of dual task was beneficial for performance under pressure but harmful when used in training. Mixed evidence was found for analogy learning, and null effects were reported for goal setting, neurofeedback training, and reappraisal cues.”

Mindfulness and acceptance approaches to sporting performance enhancement: a systematic review. Noetel et al. (2017)

“Compared to no treatment in randomised trials, large effect sizes were found for improving mindfulness, flow, and performance, and lower competitive anxiety. Evidence was graded to be low quality, meaning further research is very likely to have an important impact on confidence in these effects…A number of studies found positive effects for mindfulness and acceptance interventions; however, with limited internal validity across studies, it is difficult to make strong causal claims about the benefits these strategies offer for athletes.”

Influence of chronic stretching on muscle performance: Systematic review. Medeiros et al (2017)

In 28 studies that examined the effects of chronic stretching on muscular performance, 14 reported increases in performance, while the rest reported no difference (none reported decreases in performance). All of the studies reported improvements in performance used dynamic tests, while no measures of isometric strength improved. This systematic review was discussed in Volume 1, Issue 4 of MASS.

The Effects of Injury Prevention Programs on the Biomechanics of Landing Tasks: A Systematic Review With Meta-analysis. Lopes et al. (2017)

Injury prevention programs aimed at altering biomechanical profiles associated with ACL injury risk seem to be effective. Specifically, they seem to help increase knee and hip flexion angles during landing tasks (meaning people are absorbing force more effectively, rather than getting a big “shock” when they land), and decrease knee abduction moments (knee caving). The fact that landing mechanics are trainable is important information for coaches who train athletes (specifically female athletes in sports that require a lot of jumping).

Effects of creatine supplementation on cognitive function of healthy individuals: A systematic review of randomized controlled trials. Avgerinos et al. (2018)

Creatine supplementation may improve short-term memory and reasoning ability, especially in older adults. The effects on memory are larger in vegetarians than omnivores. Creatine supplementation doesn’t seem to affect other cognitive domains.

The effect of resistance exercise on sleep: A systematic review of randomized controlled trials. Kovacevic et al. (2018)

“Chronic resistance exercise improves all aspects of sleep, with the greatest benefit for sleep quality. These benefits of isolated resistance exercise are attenuated when resistance exercise is combined with aerobic exercise and compared to aerobic exercise alone. However, the acute effects of resistance exercise on sleep remain poorly studied and inconsistent. In addition to the sleep benefits, resistance exercise training improves anxiety and depression. These results suggest that resistance exercise may be an effective intervention to improve sleep quality.”

The epidemiology of injuries across weight-training sports. Keogh and Winwood (2017)

Bodybuilding has the lowest injury risk (0.24-1 injuries per 1,000 hours) and strongman and highland games have the highest injury risk (4.5-7.5 injuries per 1,000 hours), while weightlifting and powerlifting fall in the middle. A more recent meta-analysis by Rodríguez and colleagues looked at injury rates in CrossFitters, finding injury rates comparable to those seen in powerlifters and weightlifters.

Is core stability a risk factor for lower extremity injuries in an athletic population? A systematic review. De Blaiser et al. (2018)

Low core stability may increase athletes’ risk of lower extremity injuries.

Melatonin for the prevention and treatment of jet lag. Herxheimer and Petrie (2002)

Melatonin taken before bed helps you adapt to a new time zone when traveling, reducing symptoms of jet lag. Doses between 0.5mg and 5mg seem to be effective (with 5mg helping more than lower doses), and fast-release pills seem to work better than slow-release pills. While melatonin can help when only crossing a couple time zones, it appears that its effects are most notable when crossing 5+ time zones.

Association of Efficacy of Resistance Exercise Training With Depressive Symptoms: Meta-analysis and Meta-regression Analysis of Randomized Clinical Trials. Gordon et al. (2018)

Resistance training seems to aid in decreasing depressive symptoms. This is rather unsurprising, as exercise in general helps decrease depressive symptoms. However, resistance training seems to work just as well as aerobic training, if not slightly better (“When directly comparing the effects of resistance exercise training and aerobic exercise training, a small, nonsignificant mean effect change favoring resistance exercise training was found”). It’s possible that this meta-analysis overestimates the effects of resistance exercise on depression, however. The authors note that higher-quality studies tended to find smaller (though still positive) effects than lower-quality studies.

Effects of Strength Training on Running Economy in Highly Trained Runners: A Systematic Review With Meta-Analysis of Controlled Trials. Balsalobre-Fernandez et al. (2016)

In really well-trained runners, resistance training (generally a combination of lifting and plyometrics) has a large, beneficial effect on running economy. A 2018 systematic review by Blagrove et al. on trained (but not quite as well-trained) broadly agrees with these findings, adding, “Time trial (TT) performance (1.5–10 km) and anaerobic speed qualities also tended to improve following ST. Other parameters [maximal oxygen uptake (VO2max), velocity at VO2max, blood lactate, body composition] were typically unaffected by ST.” In other words, it appears that strength training primarily improves running performance by increasing speed and running economy, without negatively affecting purely aerobic variables.

A Systematic Review of the Effects of Resistance Training on Body Image. SantaBarbara et al. (2017)

“The majority (8 of 11) of studies concluded that resistance training can significantly improve multiple dimensions of body image, including body satisfaction, appearance evaluation, and social physique anxiety…Overall, resistance training seems to have the potential to improve body image in adults, but future high-quality studies with more rigorous testing methods and study designs are needed.”

Strength training as superior, dose-dependent and safe prevention of acute and overuse sports injuries: a systematic review, qualitative analysis and meta-analysis. Lauersen et al. (2018)

Strength training may reduce the risk of sports injuries by approximately 2/3rds.

Muscle Dysmorphia Symptomatology and Associated Psychological Features in Bodybuilders and Non-Bodybuilder Resistance Trainers: A Systematic Review and Meta-Analysis. Mitchell et al. (2016)

Bodybuilders display greater symptoms of muscle dysmorphia on all aspects of Muscle Dysmorphia Inventory (MDI) than people who lift weights but aren’t competitive bodybuilders. Furthermore, higher levels of muscle dysmorphia were positively associated with increased anxiety, depression, and neuroticism, and negatively associated with self-concept and self-esteem.
