What has been found in studies that employed interset cooling?

Greater electromyography amplitude

Higher rating of perceived exertion

Lower perceived arousal levels

What is theorized to occur as a result of interset cooling?

Acute decrease in excitation and motor unit recruitment in muscle

Restricted lactate accumulation during resistance exercises

Increase in mental alertness during subsequent training sets

What was the primary difference in the methodology used by the Kwon et al. and the McMahon et al. studies?

Kwon et al. used a lower temperature for the palm cooling group

McMahon et al. used a shorter duration for the palm cooling group

McMahon et al. used a palm heating condition in one of the groups

What effect on heart rate was found between palm cooling and nonpalm cooling conditions across five previous studies?

No difference was found between conditions

Heart rate was lower in the palm cooling condition

Heart rate was lower in the nonpalm cooling condition

What methodological concern was found in the Grahn et al. studies on the effects of palm cooling on pull-up performance?

A custom-built hand cooling device was utilized

Only trained individuals participated in the intervention

There was no random assignment to starting conditions

What was the effect of sole cooling leg press performance?

More reps were performed across the final three sets in the cooling condition

The electromyography (EMG) amplitude of the vastus lateralis was higher in the noncooling condition

Cooling and noncooling conditions led to significant increases in leg press 1RM

What cooling method did the Garg and Batra study use?

Water bath

Foot device

Ice packs

What limitation was present in the Wu et al. study?

Testing sessions were performed on the same day

Maximal strength testing was based on predicted 1RM

Water baths were used for the cooling condition

Why are maximum voluntary isometric contractions (MVICs) more generally accepted as superior to dynamic maximum voluntary contractions (DMVCs)?

Greater likelihood of maximally activating the involved musculature

Greater reliability values during the performance of weighted exercise

Lower risk of injury to participants during their application

What recommendation is given for future research on interset cooling to rule out potential confounding from the placebo effect?

Baseline testing

Blinding of conditions

Randomization of protocols
