Abstract
Resistance training (RT) offers benefits to both men and women https://lovingwomen.org/fi/blog/treffikulttuuri-brasiliassa/. 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 < 0.01).> 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) even offers advantageous assets to both males and females. Indeed, the health great things about RT become but are not limited to: reduced gastrointestinal transit date; shorter danger of cancer of the colon (Koffler et al., 1992); increased asleep metabolic process (Campbell ainsi que al., 1994; Paoli ainsi que al., 2012); enhanced glucose metabolism (Hurley, 1994); improved blood-lipid pages (Stone ainsi que al., 1982; Hurley et al., 1988); less sleeping blood circulation pressure (Harris & Holly, 1987; Colliander & Tesch, 1988); enhanced bone nutrient thickness (Menkes mais aussi al., 1993); pain and discomfort reduction of these experiencing joint disease (Rall et al., 1996); reduced low back pain (Deyssig ainsi que al., 1993; Weinsier mais aussi al., 1995); increased self-reliance (Westcott, 1995); and, increased maximum cardiovascular strength (Steele et al., 2012). Particularly, increased fuel and you can muscles, the primary results of RT, were confirmed to minimize the risk of the-produce death (Newman mais aussi al., 2006; Ruiz et al., 2008; Artero mais aussi al., 2011; Srikanthan & Karlamangla, 2014). However, whether there are sex-specific responses to help you RT was presently uncertain. Based on Dreyer et al., (2010), generally men enjoys 10 minutes a great deal more distributing testosterone than just feminine. Chest human anatomy may have even more androgen receptors than simply lower body human body (Kadi et al., 2000). Thus, you are able that the hormone improvement you’ll enable better advancement out of higher limb human anatomy when you look at the dudes compared to feminine having RT.
) examined body structure inside the 268 men and you can 2 hundred female using magnetic resonance imaging and discovered upper body muscles proportion was greater when you look at the dudes than simply female (42.9 vs. 39.7%). Similar abilities had been used in opposition-taught victims from the Alway mais aussi al. (1989), just who compared men and women weight lifters. They stated that, even with starting the same studies volume and you can performed comparable training apps, the latest muscle mix-sectional part of the biceps brachii was large inside the men than just in females. Moreover, Kvorning et al. (2006) learned that the consequences off testosterone to the power gains might possibly be significantly more pronounced than muscle progress. Hence, it could be hypothesized that sex you will determine the fresh new electricity effect way more as compared to upsurge in strength in reaction to help you RT.
Early in the day degree reported that folk carrying out a similar RT system failed to disagree from inside the power gains, both natural and you may relative, towards the lower limbs (Ivey ainsi que al., 2000; Galvao mais aussi al., 2006; Dorgo ainsi que al., 2012). Fisher ainsi que al. (2014) keeps recently claimed the power development of female and male students off a personal RT facility both for top and lower human body exercises. There were equivalent absolute strength growth but really people got a little deeper cousin fuel growth and you can energy progress according to body bulk. However, lady inside study had trained for approximately double the new period of men. Most other education examining the chest report contradictory findings with a few recommending deeper natural development in the men (O’Hagan et al., 1995; Abe ainsi que al., 2000) and you may better relative development in women. Someone else claimed zero distinctions (Davies mais aussi al., 1988; Abe mais aussi al., 2000). Yet not, it’s been argued from the Abe ainsi que al. (2000) that many of the earlier studies and that used sex contrasting to have one another power and you may muscular hypertrophic transform have been impeded by reasonable analytical stamina through small sample items (all of the ?20 participants).
