It is evident within the literature that both Males and Females can build muscle in response to resistance training (26), some stating the relative increase in muscle mass is similar between both genders (27), however some studies demonstrated females having greater relative strength increases post resistance training (28).
In addition, females can recovery quicker due to less neuromuscular fatigue when training loads are controlled, it maybe be advantageous for females to train with higher volume and/or loads (29).
However, the relatively of mass will dependant on the size of the individual, as males naturally have higher lean body mass (27) .
We can see that absolute hypertrophy adaptations are greater in males, primarily due to females demonstrating lower levels of specific hormones, such as testosterone, free testosterone an insulin-like growth factor (30).
Female hormone concentration changes significantly throughout the monthly menstrual cycle, specifically Estrogen and Progesterone , being low in the early follicular phase and high in the luteal phase (31).
Estrogen positively correlates with muscle mass due to it affecting the release of GH, IGF-1 and insulin (32), as previously mentioned are key components in promoting a hypertrophic response, specifically through metabolic stress , and Progesterone having anti-oestrogenic effects (33).
Despite this, literature states that muscular hypertrophy is not effected by any stage of the menstrual cycle, with adaptations being consistent throughout (31).
However, performance is shown to decrease with the early follicular phase, later enhanced throughout both the early ovulatory phase and mid luteal phase (33).
This maybe be something to consider when programming and monitoring female athlete's if there are apparent decreases/increases in progression.
Many individuals struggle to know where to start within female bodybuilding as some see this as completely 'Alien' to male bodybuilding, when reality they share more similarities than differences
Following from the previous key points, in this video we will discuss how to use this moving forward for prescribing to female athletes.
