Lipid and Lipoprotein Changes in Premenstrual Women Following Step Aerobic Dance Training

Abstract

Exercise training can improve lipid and lipoprotein concentrations and reduce the risk of heart disease. Little information is available concerning aerobic dance training and lipoprotein concentration changes in women. The purpose of this study was to compare the effects of two different methods of step bench training on cardiorespiratory fitness, body composition, and lipoprotein concentrations in college-aged females. Subjects were assigned to one of three groups: a traditional continuous step (CS), an interval step group (IS), or a non-exercise control group (C). The CS and the IS groups participated in three 50-minute sessions for 12 weeks. The CS session included a warm-up, 30-35 min of continuous bench stepping, 10-15 min of calisthenic exercises, and a 5-min cool-down. The IS sessions included a 5-7-min warm-up, 35-40 min of alternating intervals of bench stepping and non-step aerobic dance, and a 5-7-min cool-down. Target heart rates were maintained within 70 to 85% of maximal heart rate. Results showed increases in HDL-C concentrations in the IS group (p<0.05). Decreases in percent body fat were evident in both dance groups (p<0.05) and cardiovascular fitness increased in both groups (p<0.01). No changes were evident in the control group. In college-aged women, 12 weeks of IS or CS training improved cardiorespiratory fitness and body composition. In addition, IS training appears to have a greater effect on HDL-C concentrations than CS training.

Efectos de un programa de actividad física sobre la condición física en mujeres premenopáusicas

“…En primer lugar, y en relación a la resistencia aeróbica, la mejora del consumo máximo de oxígeno que muestra este estudio en el grupo de las mujeres premenopáusicas de mayor edad, coincide con otras investigaciones que lo respaldan, como: 12 semanas de ejercicio aeróbico en mujeres jóvenes (Campbell et al, 2007); 12 semanas de step tanto interválico como continuo (Mosher et al, 2005) y (Isler, 2006); mujeres de mayor edad que entrenaron 3 meses aeróbic con step (Kerschan-Schindl et al, 2002), o con un programa aeróbico (Chien, Wu, Hsu, Yang, & Lai, 2000); así como en chicas que utilizaron en las clases de step una carga en las extremidades (La Torre et al, 2005); incluido en mujeres obesas que ejercieron durante 14 meses ejercicios aeróbicos (Despres et al, 1991).…”

RESPOSTAS CARDIOVASCULARES DURANTE <em>STEP TRAINING</em> EM JOVENS UNIVERSITÁRIAS

“…McCord et al (1989) apuraram melhoria semelhante quando observaram os efeitos de 12 semanas de treino de ginástica aeróbica de baixo impacto em mulheres jovens, encontrando aumento de VO 2máx de 7% (p<0,05). A melhoria da aptidão aeróbia após step training também foi citada por Williford et al (1998), Mosher, Ferguson e Arnold (2005) e também por Kraemer et al (2001). No entanto, a melhora percentual do presente estudo (6%) foi inferior à obtida por Kraemer et al (2001), que obtiveram um aumento de 14% no VO 2máx , correspondente à variação de 30,2 ± 6,1 para 34,3 ± 5,2 ml/Kg/min antes e após o treino.…”

Letter to the Editor

“…I read the article by Mosher, Ferguson and Arnold [1] that investigated lipid and lipoprotein changes in premenstrual women following step aerobic dance training. In this study they compared the effects of 12 weeks of interval step aerobics training (IS) and continuous step aerobics training (CS) on cardiorespiratory fitness, body composition and lipid and lipoprotein concentrations.…”

“…In addition in the discussion section they stated "the increase in HDL-C concentration is the first to be documented following an aerobic dance-training program with women". When I read the article by Mosher et al [1] I was surprised by these statements because in a previous study [2] we examined and compared the effects of 8 weeks of step aerobics and aerobic dance training on blood lipid and lipoproteins. In this study 45 sedentary women college students were recruited as subjects and were randomly and equally assigned to a step aerobics group, an aerobic dancing group and the control group.…”
