- Description: Training for muscle hypertrophy can be expected to induce some increase in total body mass, and this can have positive or negative consequences for athletic performance. Positive effects may be increased strength, increased resistance to being pushed aside, and greater momentum when running, whereas possible negative effects may be reduced capacity to accelerate, decelerate, change direction, and jump. These possible effects of gaining muscle and total body mass suggest that strength and conditioning coaches should give thoughtful consideration to the amount of hypertrophy training prescribed throughout an athletes's development and should be determined by the specific needs of the athlete.

- Description: Resistance training is performed to increase muscle strength and mass. Associated benefits relate to improvements in physical performance as well as reduced risk of mortality. However, the exercise response to resistance training is largely variable. This may be attributed to individual physiological phenotype and flawed methods of standardised training. Recent efforts have been made to identify biomarkers which delineate between high and low responders to resistance training. Myokines associated with exercise-induced muscle secretome are biomarkers that potentially differentiate between individuals that experience large or small increases in muscle mass. However, the repeatability of these biomarkers in response to standardised resistance training is understudied. Therefore, this research seeks to address the inter and intra-reliability of myokines associated with resistance exercise, and if they confidently predict high and low responders to individually standardised resistance training. Development of a screening tool which reliably identifies individual trainability can have potential implications for personalised exercise physiology. © 2022

- Description: Participation in resistance training improves muscle strength and size, as well as reduced risk of chronic disease and frailty. However, the exercise response to resistance training is highly variable. In part this may be attributed to individual physiological differences. Identification of biomarkers that can distinguish between high and low responders to exercise are therefore of interest. Exhaled volatile organic compounds may provide a non-invasive method of monitoring the physiological response to resistance training. However, the relationship between exhaled organic compounds and the acute response to resistance exercise is not fully understood. Therefore, this research will investigate exhaled volatile organic compounds in acute response to resistance exercise with an aim to discover a common group of compounds that can predict high and low responders to standardised resistance training. © 2022 Elsevier Ltd
