Montgomery 2008.
Methods | Randomised controlled trial (matched by playing position and anthropometrics) | |
Participants | N = 29 male basketball players, mean age 19.1 (SD: 2.1) | |
Interventions | All groups: Carbohydrate and stretching CWI group (n = 10): Immersion to mesosternale level in 11°C water, 5 x 1 minute. Between immersions participants rested passively for 2 minutes in ambient air (23°C) Compression (n = 10): Full length compression garments (18 mm/Hg) post game and overnight (18 hours) Control (n = 9): Carbohydrate and stretching only, post game carbohydrate snack (1 g/kg body mass) and 600 ml of fluid in sports drink followed by a standardised programme of 10 stretches (bilateral leg and lower back, each stretch held for 15 seconds, 2 sets) |

Outcomes |
Subjective recovery
Rating of general fatigue (visual analogue scale, 1 "not at all" to 10 "extremely tired") Pain Leg soreness (visual analogue scale, 1 "normal" to 10 "extremely sore") Power Vertical jump (cm) Functional assessment Time to complete exercise test (20 sprint; repeated sprint; agility test; all seconds) Swelling Limb girth (cm, calf and thigh) ROM Sit and reach flexibility test (cm) [Follow‐up: 24 hours (after finishing the 3 day tournament)] |
|
Exercise type / intensity | 3 day basketball tournament (48 minute game each day), comprising a total of 144 minutes of basketball in mean temperature of 23.2°C | |
Time between completing exercise and initiating intervention | ˜10 minutes (all groups undertook control after each game estimated to take 10 minutes) | |
Participants' fitness level | Regularly competing in state competitions; training load of 8 to 10 hours per week | |
Notes | Our analysis only included outcomes recorded at the end of the tournament, ˜24 hrs after the final game ["pre tournament tests were repeated on the morning of the 4th day" (pg. 1137)]. Outcomes (subjective recovery, pain, muscle power) recorded after each game were not extracted or included in our analysis. Measurement device for vertical jump not clear |

Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Unclear risk | 'randomised controlled trial' (Methods, experimental design, pg. 1137) players matched for positional and anthropometric characteristics and assigned to one of three treatment groups (Methods, experimental procedures, pg. 1137) |
Allocation concealment (selection bias) | Unclear risk | No details in manuscript |
Blinding (performance bias and detection bias) Participants | High risk | No blinding. |
Blinding (performance bias and detection bias) Personnel | High risk | No blinding. |
Blinding (performance bias and detection bias) Outcome assessors | Unclear risk | No details in manuscript |
Incomplete outcome data (attrition bias) All outcomes | Unclear risk | No details on drop outs, exclusions, missing data or approach to analysis (per protocol / ITT) |
Selective reporting (reporting bias) | Low risk | No published protocol available Outcomes and follow‐ups stated in methods Means and SD presented by intervention group for all outcomes, at all follow‐ups |
Other bias | Low risk | Cumulative game time is expressed for participants within each treatment group, and is similar (also used as a covariate in statistical analysis) Participants undertook standardised carbohydrate ingestion and stretching between games |
