The Effect of Remote Voluntary Muscle Contractions on Strength and Power Performance

This study was designed to examine the effects of RVC by jaw clenching with a mouthpiece (MP) and with the jaw in a relaxed state without a mouthpiece (R-noMP) on acute muscular performance. Thirteen subjects (10 males and 3 females, age 22.9 + or - 1.9 yrs, ht 174.2 + or - 9.1 cm, body mass 77.3 +...

Description
Summary:This study was designed to examine the effects of RVC by jaw clenching with a mouthpiece (MP) and with the jaw in a relaxed state without a mouthpiece (R-noMP) on acute muscular performance. Thirteen subjects (10 males and 3 females, age 22.9 + or - 1.9 yrs, ht 174.2 + or - 9.1 cm, body mass 77.3 + or - 14.6 kg) volunteered to perform a grip dynamometer test with a Jamar Grip Dynamometer (Gr), a Vertical Jump Test (VJ), a 6 repetition maximum (RM) chest press (CP) and a 6 RM leg extension (LE) on Nautilus equipment. Statistical analysis revealed no significant difference between MP vs R-noMP for grip strength (35.6 vs 35.5 kg), vertical jump (40.6 vs 40.9 cm), 6 RM chest press (47.5 vs 47.4 kg) and 6RM leg extension (44.4 vs 44.1 kg), respectively.
