Effects of compression clothing on performance and recovery

 According to this study there is small benefit of compression clothing to performance and moderate benefit to recovery.

Abstract

To assess original research addressing the effect of the application of compression clothing on sport performance and recovery after exercise, a computer-based literature research was performed in July 2011 using the electronic databases PubMed, MEDLINE, SPORTDiscus, and Web of Science. Studies examining the effect of compression clothing on endurance, strength and power, motor control, and physiological, psychological, and biomechanical parameters during or after exercise were included, and means and measures of variability of the outcome measures were recorded to estimate the effect size (Hedges g) and associated 95% confidence intervals for comparisons of experimental (compression) and control trials (noncompression). The characteristics of the compression clothing, participants, and study design were also extracted. The original research from peer-reviewed journals was examined using the Physiotherapy Evidence Database (PEDro) Scale. Results indicated small effect sizes for the application of compression clothing during exercise for short-duration sprints (10-60 m), vertical-jump height, extending time to exhaustion (such as running at VO2max or during incremental tests), and time-trial performance (3-60 min). When compression clothing was applied for recovery purposes after exercise, small to moderate effect sizes were observed in recovery of maximal strength and power, especially vertical-jump exercise; reductions in muscle swelling and perceived muscle pain; blood lactate removal; and increases in body temperature. These results suggest that the application of compression clothing may assist athletic performance and recovery in given situations with consideration of the effects magnitude and practical relevance.

Excellent review looking at brain atrophy and exercise

"In summary, we conclude from this review that there is mounting evidence that BDNF protein expression
plays an important role in age-related hippocampal atrophy and that geriatric depression magnifies hippocampal atrophy and risk for AD through BDNF pathways while exercise enhances hippocampal morphology and physiology by elevating the production of BDNF. Future research is needed to determine the extent to which BDNF mediates hippocampal atrophy and memory impairment or is a biomarker for other cellular and molecular changes."

Carbohydrate drinks and endurance performance

Study supports what I have been recommending for years, during endurance events like 10km or longer hydrate using a drink containing 4-7% carbohydrate for maximum performance and the least amount of digestive distress.In the study below, the carbohydrate was supplied in grams of CHO per liter of fluid per hour. 70 grams/liter is equivalent to 7% CHO in the drink.

Abstract

ABSTRACT: There is a lack of consensus regarding the optimal range of carbohydrate (CHO) ingestion rates recommended for endurance athletes. Purpose: This study investigated the relationship between CHO dose and cycling time-trial performance to identify an optimal range of CHO ingestion rates for endurance performance. Methods: Fifty-one cyclists and triathletes (28 ± 7 yr, mean ± SD) across four research sites completed four trials. Each trial consisted of a 2-h constant load ride at 95% of the workload that elicited a 4-mM blood lactate concentration immediately followed by a computer-simulated 20-km time-trial, which subjects were asked to complete as quickly as possible. Twelve CHO electrolyte (18 mmol•L Na, 3 mmol•L K, and 11 mmol•L Cl) beverages (three at each site) were tested in a double-blind manner, providing subjects 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, and 120 g CHO (1:1:1 glucose-fructose-maltodextrin)•h during the 2-h constant load ride at a fluid intake rate of 1 L•h. All subjects also consumed a non-caloric placebo on one counterbalanced test occasion. Data were natural log transformed, subjected to a mixed model analysis, and are reported as adjusted treatment means. Results: We estimate incremental performance improvements of 1.0, 2.0, 3.0, 4.0, and 4.7% at 9, 19, 31, 48 and 78 g•h respectively with diminishing performance enhancement seen at CHO levels greater than 78 g•h. Conclusion: CHO beverage ingestion and endurance (~160 min) performance appear to be related in a curvilinear dose-response manner, with the best performance occurring with a CHO (1:1:1 glucose-fructose-maltodextrin) ingestion rate of 78 g•h.
