Noise in Aerobic Facilities.

Cycling exercise classes may be bad for your (hearing) health

“…One study conducted by Torre and Howell of twelve 50‐minute aerobic classes found an average of 87.1 dBA was employed (range = 83.4–90.7 dBA) and that mean distortion product otoacoustic emissions were lower immediately after class attendance . Mirbod et al recorded sound levels of 93 to 96 dBA during peak exercise periods in Japanese aerobics studios and found no significant differences in mean hearing threshold levels after class attendance . Yaremchuk and Kaczor found that among 125 classes at five American health clubs, 79% of measurements were >90 dBA (range = 78–106 dBA), with participants reporting fluctuating hearing loss and tinnitus after classes 50% of the time .…”

“…10 Mirbod et al recorded sound levels of 93 to 96 dBA during peak exercise periods in Japanese aerobics studios and found no significant differences in mean hearing threshold levels after class attendance. 11 Yaremchuk and Kaczor found that among 125 classes at five American health clubs, 79% of measurements were >90 dBA (range 5 78-106 dBA), with participants reporting fluctuating hearing loss and tinnitus after classes 50% of the time. 12 In a United Kingdom-based study of aerobics classes, Nassar reported sound levels of 89 to 96 dBA, and all subjects had significantly elevated hearing thresholds after classes.…”

El análisis de la comunicación paraverbal cinésica y proxémica de los instructores de fitness mediante patrones temporales (T-patterns)

“…15, n.º 1 (enero) que les permite vincularse con los participantes en ambientes dispersos y difíciles (Castañer, Franco, Rodrigues, y Miguel, 2012;Castañer, Camerino, Anguera, y Jonsson, 2013). El componente gestual de la comunicación y los movimientos realizados esencialmente con los brazos y manos es parte integrante del proceso comunicativo (Cartmill, Goldin-Meadow, y Beilock, 2012; Kendon, 2004) y contribuye signi cativamente a su e cacia según comprobó Hostetter (2011) a partir de un metaanálisis de la oportunidad de la comunicación En los programas de tness nos encontramos con factores que di cultan la comunicación: el volumen elevado de la música, que entorpece la instrucción verbal (Alves et al, 2014;Mirbod et al, 1994;Yarenchuk y Kaczor, 1999); la adecuación del gesto a la ejecución del movimiento (Castañer, et al 2012;Franco, Rodrigues y Castañer, 2008), y la necesidad de mantener una proximidad espacial con los practicantes (Alves et al, 2013).…”

The Role of Music Intensity in Aerobics: Implications for Hearing Conservation

“…The remaining study, by Mirbod et al (1994), reported no significant TTS in their aerobic instructors, two minutes after their measured aerobics sessions (n=10 females, normal hearing, mean age 25.4 ± 2.4 years, mean instruction time/week = 9.4 ± 3.4 hours, total instruction time prior to testing = 1274.0 ± 474.9 hours). Before citing this as a direct contradiction to Nassar (2001), however, two factors must be considered.…”

“…Aerobics becomes an at-risk activity for NIHL when high intensity music is played in its classes. In measuring these intensities, Mirbod et al (1994) reported 93-96 dB(A) during peak exercise periods (lasting approximately 50 minutes) in three different Japanese aerobics studios. Yaremchuk and Kaczor (1999) reported 78 to 106 dB(A) (measured every five minutes) in 125 sixty-minute classes from five different American health clubs.…”
