Screen Time Impairs Swimming Performance

admin Biomechanics, Blog, Dr. John Mullen, Latest&Greatest, Training Leave a Comment

Take Home Points on Screen Time Impairing Swimming Performance: Screen time is negatively associated with isometric core strength. Screen time decreases arterial mobility. Whether it is at a computer, television, tablet, or phone, screen time has increased dramatically over the past decades. The average American teenager spends nearly 7.5 hours in front of a screen (Kaiser 2010) [and I’m sure …

What Are The Effects Of High-Intensity Training?

What Are The Effects Of High-Intensity Training?

Dr. GJohn Mullen Blog, Dr. John Mullen, Dryland, Latest&Greatest, Training Leave a Comment

Background On High-Intensity Traning High intensity, short rest exercise is commonly used in swimming and dry-land. This demanding form of training is believed to influence different energy systems with minimal research. This form of training has gained much praise almost solely on anecdotal research but is more commonly seen in dry-land and fitness enthusiast. Popular commercial programs of this variety …

Swim Practice Protein Intake

Swim Practice Protein Intake

admin Blog, Kevin Iwasa-Madge, Latest&Greatest, Nutrition/Supplements, Training 1 Comment

Take-Home Points on Swim Practice Protein Intake: Ingesting protein during training can minimize muscle breakdown from training. Protein should be ingested in smaller quantities (10-20g) than carbohydrate (up to 80g) because they are digested slower. Consume this amount of protein and carbohydrate with large amounts of liquid (1L/32oz) to prevent a hypertonic training drink that can lead to dehydration and …

Are Warm-ups Beneficial?

Are Warm-ups Beneficial?

Dr. GJohn Mullen Dr. John Mullen, Dryland, Latest&Greatest, Training Leave a Comment

Background On Warm-ups  A warm-up is beneficial for sports performance. However, the intensity of warm-ups for different race durations is not well studied. It is believed warm-up reduces anaerobic glycolytic metabolism with a parallel increase in aerobic metabolism potentially induced by a faster oxygen uptake kinematics, which may delay fatigue. This would improve middle-distance and short-endurance durations of exercise (3-10 …

Are MSTN and CKM Gene's Associated With Elite Endurance Performance?

Are MSTN and CKM Gene’s Associated With Elite Endurance Performance?

Dr. GJohn Mullen Dr. John Mullen, Training Leave a Comment

Background On MSTN and CKM Gene’s Elite aerobic athletes typically utilize extensive exercise training, expert coaching, proper nutrition, motivation, genetics, and many other factors. Genes have been associated with athletic success in sprint events, but little is known about the contribution of specific genes and sequence variants as indicators of endurance performance. Myostatin (MSTN) and muscle-specific creatine kinase (CKM) are …

Cross Education, Is The Opposite Limb Being Worked?

Cross Education: Is The Opposite Limb Being Worked?

Dr. GJohn Mullen Blog, Dr. John Mullen, Latest&Greatest, Training Leave a Comment

Background On Cross Education Strength training of one limb causes an increase in voluntary strength in both limbs. This is known as “cross-education”, “cross-training”, or “contralateral-strength-training effect”. This phenomenon occurs in both the upper and lower extremities. This strategy is commonly used when a limb is immobilized. Sariyildiz et al. evaluated whether electrical muscle stimulation (EMS) on dominant wrist flexors …

Do Kettlebells Improve Endurance

Do Kettlebells Improve Endurance?

Dr. GJohn Mullen Blog, Dr. John Mullen, Training Leave a Comment

Background On Kettlebells  Kettlebells are emerging as a favorite mode of exercise for strength and conditioning specialist. A kettlebell is a cast iron weight that resembles a cannonball with a handle. The manufacture of the kettlebell allows the center of mass to extend beyond the hand. However, clinical data on their efficacy is limited. Kettlebell advocates feel the kettlebell allows …

Optimal Training for Masters Swimmers

Erin Cameron Blog, Dr. Erin Cameron, Latest&Greatest, Training Leave a Comment

When training masters swimmers, is high volume, low intensity or low volume, high intensity superior? Or does a combination of both prove superior? We had the pleasure of discussing the answers to these questions and so much more with Mr. Lorenzo Pugliese, a researcher whose work focuses on exercise physiology, biomechanics and performance enhancement. His recent article sought to determine if increasing …

All You Need to Know About the Sympathetic Nervous System and Training

admin Blog, Injuries, Latest&Greatest, Training 1 Comment

Overload and overreaching is common in swimming. During these periods, the nervous system undergoes high levels of stress. Luckily, there are top researchers looking into the influence of training on the nervous system. This interview with PhD (c) in human performance and health research, Alexandra Coates (see her info and past research here). Alexandra is a former competitive swimmer and …
