Abstract
Resistance training (RT) offers benefits to both men and women. However, the studies about the differences between men and women in response to an RT program are not conclusive and few data are available about upper body strength response. The aim of this study was to compare elbow flexor strength gains in men and women after 10 weeks of RT. Forty-four college-aged men ( ± 2.34 years) and forty-seven college-aged women ( ± 2.96 years) participated in the study. The RT program was performed two days a week for 10 weeks. Before and after the training period, peak torque (PT) of the elbow flexors was measured with an isokinetic dynamometer. PT values were higher in men in comparison to women in pre- and post-tests (p 0.05). Effect sizes were 0.57 and 0.56 for men and women, respectively. In conclusion, the present study suggests that men and women have a similar upper body strength response to RT.
Introduction
Resistance training (RT) also provides positive points to both men and women. Indeed, the medical benefits associated with RT were but are not restricted to: reduced gastrointestinal transit go out; smaller threat of a cancerous colon (Koffler et al., 1992); improved sleep k-calorie burning (Campbell mais aussi al., 1994; Paoli mais aussi al., 2012); improved sugar metabolic rate (Hurley, 1994); enhanced blood-lipid pages (Brick ainsi que al., 1982; Hurley mais aussi al., 1988); less sleep hypertension (Harris & Holly, 1987; Colliander & Tesch, 1988); enhanced bones mineral occurrence (Menkes mais aussi al., 1993); pain and discomfort reduction for those enduring osteoarthritis (Rall ainsi que al., 1996); diminished low back pain (Deyssig mais aussi al., 1993; Weinsier et al., 1995); improved independence (Westcott, 1995); and you may, enhanced maximal cardiovascular ability (Steele et al., 2012). In particular, improved energy and you may muscles, an important aftereffects of RT, were evidenced to reduce the risk of the-lead to death (Newman et al., 2006; Ruiz ainsi que al., 2008; Artero et al., 2011; Srikanthan & Karlamangla, 2014). Although not, if you can find sex-specific answers to help you RT try at this time unclear. According to Dreyer ainsi que al., (2010), typically guys provides ten minutes so much more dispersing testosterone than female. Torso muscles possess so much more androgen receptors than simply knee system (Kadi et al., 2000). Ergo, you are able that hormones huge difference might permit better development out-of higher limb looks for the men than the women that have RT.
) investigated human body constitution within the 268 dudes and you will 200 feminine having fun with magnetized resonance imaging and found chest area muscles proportion are higher for the dudes than women (42.nine against. 39.7%). Comparable efficiency have been utilized in resistance-taught victims by Alway ainsi que al. (1989), exactly who opposed female and male bodybuilders. It stated that, even with performing the same degree frequency and you will did similar degree software, the newest muscle cross-sectional part of the biceps brachii are high from inside the males than simply in women. Furthermore, Kvorning mais aussi al. (2006) discovered that the effects of testosterone on the stamina gains could be way more noticable than simply muscle tissue progress. Thus, it could be hypothesized you to definitely sex you’ll influence the fresh new fuel effect moreso compared to the escalation in strength as a result in order to RT.
Previous degree reported that visitors creating an equivalent RT system did not differ inside the power increases, both absolute and you can cousin postordre brud svindel, towards the lower limbs (Ivey mais aussi al., 2000; Galvao ainsi que al., 2006; Dorgo mais aussi al., 2012). Fisher ainsi que al. (2014) keeps recently stated the new electricity gains regarding female and male students of a private RT facility for higher and lower human body practise. There are equivalent natural fuel growth yet , female got a little better relative strength growth and you will energy development prior to muscles bulk. But not, lady within studies had taught for approximately double new years of men. Most other studies examining the chest area statement conflicting findings with some indicating deeper absolute development inside the males (O’Hagan et al., 1995; Abe et al., 2000) and you will greater cousin gains in women. Anyone else advertised no differences (Davies et al., 1988; Abe et al., 2000). not, this has been argued by the Abe et al. (2000) a large number of the earlier knowledge hence held sex evaluations for each other power and you can muscular hypertrophic transform was impeded because of the reduced statistical stamina through brief sample brands (all the ?20 users).
