PURPOSE: To study the effects of a commercially available negative ion “energy band” on peak anaerobic capacity and recovery.
METHODS: Twenty one participants (age = 28.2 + 5.2 yrs, ht = 172.1 + 1.0 cm, wt = 83.3 + 17.5 kg) completed two, 30-sec Wingate trials on a Monark 817E cycle ergometer while wearing either a True Power™ Energy Band (TB) (True Power LLC) or silver bracelet placebo (PB) (Hobby Lobby). Trial order was counterbalanced and each trial separated by approximately 1 week. Physical Activity Readiness Questionnaire (PAR-Q) and consent form were completed before testing, and participants were asked to refrain from consuming a heavy meal or caffeine at least 3 hours before testing. Wingate testing was preceded by a 5-min warm up consisting of cycling for 3 min at 50 rpm and 20% of prescribed Wingate load (.086 * body mass [kg]), and 5-sec sprints at 25%, 50%, 75%, and 100% of prescribed load every 30 sec. After resting 3 min, participants commenced Wingate testing. Recovery consisted of cycling 10 min at 50rpm and 20% Wingate load. HR and oxygen consumption were measured throughout testing using a HR monitor (Polar) interfaced to a metabolic system (Parvo Medics’ TrueOne 2400). RPE (Borg 6-20 Scale) was recorded immediately following Wingate test and at 5 and 10 min of recovery.
RESULTS: There were no significant differences between each trial (TB vs. PB) for:
TB
PB
O2 Consumption (L/min)
Rest
0.36 + 0.07
0.34 + 0.08
Post Wingate
1.84 + 0.40
1.82 + 0.40
5-min recovery
1.55 + 0.36
1.55 + 0.34
10-min recovery
1.48 + 0.35
1.48 + 0.35
Heart Rate (BPM)
Rest
85.2 + 12.8
84.0 + 10.2
Post Wingate
164.5 + 11.3
163.6 + 15.7
5-min recovery
146.3 + 15.0
144.0 + 17.3
10-min recovery
144.7 + 15.5
142.7 + 17.9
RPE
Post Wingate
18.0 + 2.0
18.0 + 2.1
5-min recovery
13.6 + 2.5
13.0 + 1.5
10-min recovery
12.1 + 2.1
11.7 + 1.6
Total Revolutions
39.7 + 8.7
39.4 + 8.7
Peak Revolutions/5 sec
10.1 + 2.0
10.0 + 2.2
CONCLUSION: It does not appear that True Power™ Energy Bands have any discernable effect on an individual's anaerobic capacity and recovery.
