Sports Science Dudes

Alyssa Parten, PhD, CSCS, is a Clinical Assistant Professor of Kinesiology at The University of Alabama. Her research centers on resistance training and female physiology, with a focus on strategies to enhance female exercise performance and how resistance training may impact female long-term health. Dr. Alyssa Parten shares her expertise on female physiology and resistance training, challenging conventional wisdom about menstrual cycle-based training while advocating for personalized, auto-regulated approaches instead.• Clinical assistant professor of kinesiology researching resistance training in female physiology• Competitive powerlifter with a 292.5 lb squat, 187.5 lb bench press, and 375 lb deadlift at 138 lbs bodyweight• Research found no significant metabolic differences between follicular and luteal phases• Auto-regulation through RPE is more effective than strict cycle-based training programs• Normal menstrual cycle length ranges from 24-39 days, with significant individual variation• Traditional powerlifting and bodybuilding training are both effective for female physiology• Leading FEMPOWER research team studying women-specific training adaptations• Current projects examine post-activation performance enhancement protocols for women• Future research will explore resistance training benefits during perimenopause and menopause

Dr. Andy Sparks, a nutritional expert and Research Innovations Manager at Maurten AB, dives deep into the often underestimated benefits of sodium bicarbonate for athletic performance. He explains how it functions as a buffer during high-intensity exercise, reducing pain perception and aiding long-distance athletes. Key points include innovative delivery methods to minimize GI distress and tailored dosing strategies for optimal effectiveness. Plus, discover its potential in various sports, from sprints to endurance events, and the exciting synergy with other supplements like caffeine.

Kristy Storschuk, a PhD candidate in muscle physiology at Queen's University, dives into the nuances of Zone 2 training and fasting. She challenges common myths, revealing that exercise intensity may drive better mitochondrial adaptations than heart rate zones. Kristy also discusses how elite athletes' benefits often stem from high-intensity work rather than just Zone 2 training. Additionally, she explores the differences in muscle responses to fasting between rodents and humans, advocating for individualized nutritional approaches and emphasizing the importance of recovery.

Dr. Arny Ferrando shares groundbreaking research on essential amino acids, muscle protein synthesis, and emerging cognitive benefits of targeted amino acid supplementation.• Essential amino acids (EAAs) produce greater anabolic response than whole proteins due to requiring no digestion and producing higher blood concentrations• Free-form EAAs need only 15 grams for maximal response compared to 40 grams of whey protein• Taking EAAs one hour before exercise provides optimal muscle protein synthesis due to increased blood flow during workouts• Physiological aging matters more than chronological age when determining nutritional interventions• New research shows EAAs may enhance cognitive function by modulating dopamine/serotonin balance• EAA supplementation helps mitigate muscle loss during bed rest or recovery from injury• The mTOR pathway's connection to cancer is often misinterpreted and shouldn't discourage proper protein intake• Testosterone replacement therapy should be based on symptoms rather than numbers alone• Higher protein turnover is energetically expensive, potentially helping with weight managementTry combining essential amino acids, protein, and creatine supplementation for optimal results, especially when recovering from injury or dealing with age-related muscle loss.

Dr. Dean St Mark, a pharmacologist and product formulator for UK-based brand called Supplement Needs, brings his expertise on testosterone, PEDs, and their health implications to the podcast.• TRT usage has shifted from older men to being prescribed for men in their mid-20s with hypogonadism• Many users push beyond replacement therapy (800 ng/dL) into enhancement territory (1200+ ng/dL) • Androgens impact brain chemistry, creating psychological dependency through altered dopamine thresholds• Female athletes face unique risks including potentially irreversible virilization effects like voice deepening• Polypharmacy and arbitrary dosing based on gym advice rather than science increases health risks• "FemTest" protocols inappropriately extrapolate safety data from PCOS patients to healthy female athletes• Excessive size and muscle mass may contribute to early mortality in bodybuilders (40-60 years old)• EPO can benefit endurance athletes but requires careful monitoring due to blood viscosity concernsFind Dr. Dean St Mark on Instagram @DeanSTM.

Dr. Matt Frakes shares his experience as Director of Performance Nutrition for the New York Giants, focusing on optimizing player performance through individualized nutrition strategies and building trusting relationships with athletes.• Breaking into sports nutrition careers requires networking, professionalism, and willingness to do grunt work before showcasing talent• College and pro settings differ dramatically—pros have more autonomy and often work with their own nutrition and training specialists• Athletes can build too much lean muscle mass relative to their skeletal structure, increasing injury risk• Performance nutrition requires an individualized approach considering body composition, position demands, and training phase• Nutritional strategies for brain health include omega-3 fatty acids, anti-inflammatory foods, and creatine supplementation• Recovery modalities like sauna, cryotherapy, red light therapy and compression are widely used at the professional level• Successful teams require strong interdisciplinary communication between performance staff, medical team and coachesDr. Frakes will be delivering the President's Lecture at the 22nd International Society of Sports Nutrition Conference, June 23-25 in Delray Beach, Florida.

Dr. Katie Vasenina shares her journey from standout tennis player to sports scientist, offering unique insights on sport-specific training methodologies and nutritional interventions for athletes. Her research challenges conventional wisdom about asymmetrical training, collagen supplementation effectiveness, and dietary approaches for optimal recovery and performance.• Former Division I tennis player who specialized in sport-specific training• Completed her PhD studying various topics including collagen supplementation and muscle damage recovery• Found early sport specialization (before age 9) correlates with increased injury rates• Discovered traditional strength coaches often apply inappropriate training methods to tennis players• Researched collagen supplementation, finding it ineffective for muscle recovery but potentially beneficial for tendons• Conducted innovative study comparing vegan vs omnivore diets for muscle damage recovery• Found no performance differences between diet groups when protein intake was equated (1.4-1.5g/kg)• Currently training for a 50km ultra obstacle race (not sure she should do it!)• Starting a new position at the University of Tampa in August 2024• Planning future research on collagen supplementation with vitamin C for tendon healthCatch Dr. Vasenina's presentation "Collagen Doesn't Do Sh*t, Except When It Does" at the ISSN conference in Delray Beach, June 23-25.
