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.

Addition

Resistance training (RT) even offers positive points to both males and females. In reality, the medical benefits associated with RT were however they are not restricted to: reduced intestinal transportation go out; quicker chance of cancer of the colon (Koffler ainsi que al., 1992); increased resting kcalorie burning (Campbell et al., 1994; Paoli et al., 2012); improved sugar metabolic rate (Hurley, 1994); increased blood-lipid profiles (Brick mais aussi al., 1982; Hurley et al., 1988); smaller asleep blood pressure level (Harris & Holly, 1987; Colliander & Tesch, 1988); enhanced limbs mineral thickness (Menkes et al., 1993); discomfort and pain protection for these experiencing osteoarthritis (Rall ainsi que al., 1996); reduced low back pain (Deyssig mais aussi al., 1993; Weinsier et al., 1995); increased independence (Westcott, 1995); and, improved maximal aerobic potential (Steele et al., 2012). In particular, increased electricity and muscle, the key effects of RT, was confirmed to attenuate the possibility of all-produce mortality (Newman et al., 2006; Ruiz mais aussi al., 2008; Artero mais aussi al., 2011; Srikanthan & Karlamangla, 2014). Although not, Bla gjennom disse karene if or not you can find sex-specific responses to RT try at this time not sure. Predicated on Dreyer mais aussi al., (2010), in general guys provides ten moments a whole lot more distributing testosterone than feminine. Torso looks have even more androgen receptors than simply leg human body (Kadi mais aussi al., 2000). Ergo, it is possible that this hormones distinction you are going to permit deeper innovation regarding top limb system when you look at the guys as compared to women with RT.

) investigated muscles structure in 268 guys and you can two hundred feminine using magnetic resonance imaging and discovered upper body muscle proportion try deeper when you look at the dudes than women (42.nine vs. 39.7%). Comparable performance were used in resistance-educated subjects from the Alway et al. (1989), just who compared female and male bodybuilders. It stated that, even with undertaking a similar studies regularity and you may performed similar knowledge software, brand new muscle get across-sectional part of the biceps brachii is actually high from inside the males than simply in women. Additionally, Kvorning mais aussi al. (2006) found that the effects away from testosterone with the power gains would be a great deal more obvious than simply muscle growth. Hence, it can be hypothesized that sex might dictate the new strength effect way more compared to upsurge in muscle tissue in reaction to help you RT.

Earlier in the day knowledge stated that someone undertaking a similar RT program did not disagree from inside the electricity increases, each other sheer and you will cousin, into the hip and legs (Ivey et al., 2000; Galvao et al., 2006; Dorgo ainsi que al., 2012). Fisher et al. (2014) provides recently advertised the fresh new stamina increases regarding female and male trainees regarding a private RT facility both for top and lower human anatomy practise. There were comparable sheer stamina growth yet females got some higher relative stamina gains and you may power gains in line with human body mass. not, women within this research got trained for about double this new cycle of men. Almost every other degree examining the upper body report conflicting findings with a few suggesting higher natural gains when you look at the guys (O’Hagan et al., 1995; Abe et al., 2000) and you may higher relative growth in females. Anyone else said no distinctions (Davies ainsi que al., 1988; Abe et al., 2000). But not, it’s been contended of the Abe ainsi que al. (2000) that many of the earlier knowledge hence held sex comparisons to own each other strength and you may muscular hypertrophic transform have been impeded because of the lower mathematical strength as a result of brief decide to try versions (all of the ?20 members).
