hip extensor musculature in clinical LBP populations arises from the interplay between hip function and LBP. 24 , 25 While LBP can also slow the recovery from muscle fatigue of lumbar spine extensor musculature, 26 – 28 it is not known how LBP affects recovery from hip muscle fatigue. LBP

Australian Football (AF) is an intermittent team sport involving rapid accelerations and decelerations, collisions, and large distances covered at a high intensity. 1 The competitive season can produce high levels of fatigue, and optimizing recovery in order to maximize performance is critical. 1

To determine the effect of wearing compression socks between repeated running bouts on perceptual, physiological, and performance-based parameters.


Twelve well-trained male runners (mean ± SD 5-km time 19:24 ± 1:19 [min:s]) recorded their perceptions of the efficacy of compression socks for recovery before completion of 2 experimental sessions. Each session consisted of two 5-km running time trials (TT1 and TT2) on a treadmill, with a 1-h recovery period between. In a randomized crossover design, 1 session required participants to wear compression socks during the recovery period, and no compression socks were worn between TTs in the other session (control).


Running performance between TT1 and TT2 for runners wearing compression socks was similar between TTs (mean Δ 5.3 ± 20.7 s, d = 0.07, P = .20), whereas for control runners, performance significantly decreased in the second TT (mean Δ 15.9 ± 13.3 s, d = 0.19, P < .01). When grouped by perception of efficacy for compression socks, participants with strong beliefs (n = 7) experienced improved subsequent running performance with compression socks (mean Δ –3.6 ± 19.2 s, d = 0.05, P = .32) compared with those with neutral or negative perceptions (n = 5; mean Δ 17.9 ± 17.0 s, d = 0.19, P = .04). Cross-sectional area of the calf and muscle soreness were significantly reduced during the recovery period with the use of compression socks (P < .01), whereas ratings of fatigue showed no difference between conditions.


Wearing compression socks between repeated running bouts can aid recovery and subsequent performance. Furthermore, subsequent exercise performance may be even further enhanced when athletes believe in the efficacy of compression socks to assist in recovery between exercise bouts.

Sleep is regarded as one of the best recovery strategies available to elite athletes, with sleep playing an important role in performance, cognitive function, mood, illness, and metabolism. 1 Evidence suggests that athletes may have poorer sleep quality and quantity than the general population, 2

To determine the effect of carbohydrate feeding on muscle glycogen resynthesis, 8 male cyclists pedaled for 2 hrs on a cycle ergometer at 70% of VO2max while consuming either a 10% carbohydrate solution (CHO) or a nonnutritive sweet placebo (No CHO). Muscle biopsies were obtained from the vastus lateralis prior to, immediately postexercise, and at 2,4, and 24 hrs of recovery. Blood samples were taken before and at the end of exercise, and at specified times during recovery. During both trials food intake was withheld for the first 2 hrs of recovery, but at 2 hrs postexercise a 24% carbohydrate solution was ingested. The rate of muscle glycogen resynthesis during the first 2 hrs of recovery was similar for the CHO and No CHO trials. Following ingestion of the 24% carbohydrate supplement, the rates of muscle glycogen resynthesis increased similarly in both trials. These similar rates of resynthesis following ingestion of the carbohydrate supplement were obtained despite significantly greater serum glucose and insulin levels during the No CHO trial. The results indicate that the carbohydrate feedings taken during exercise had little effect on postexercise muscle glycogen resynthesis.

This paper builds on the concept of mental health recovery to critically examine three football projects in the United Kingdom and their effects on the recovery process. Drawing on qualitative research on the lived experiences of mental health clients and service providers across the three projects, we explore the role of football in relation to three components of recovery: engagement, stigma, and social isolation. The findings indicate how the projects facilitated increased client engagement, peer supports, and the transformation of self-stigma. The perception of football as an alternative setting away from the clinical environment was an important factor in this regard. Yet, the results also reveal major limitations, including the narrow, individualistic conceptualization of both recovery and stigma within the projects, the reliance on a biomedical model of mental illness, and the potentially adverse consequences of using football in mental health interventions.
