Here is what the participants had to say Wednesday:
DANNY GARCIA
"[On going up to 147 pounds] You're going to see a lot more energy in the ring. You'll see a smarter fighter. I'll have more agility and we're going to go in there to get the job done.
"We're just working hard. At the end of the day it's about being 100 percent prepared. I did everything right this camp and I'm ready.
"The game plan is to go in there and be Danny Garcia and be spectacular. I don't know which Paulie to expect but I'm prepared for any version of him we see. I'm sparring a lot of guys who move and guys who come forward so I'm ready for anything.
"If we're both at 100 percent then I'll take my 100 percent over his without a doubt. My style is made to beat any fighter in the game. I'm sure he trained hard but we're going to get this victory.
"I'm only focused on being a fighter. I don't think anybody can beat a 110 percent Danny Garcia. At the end of the day, I know I beat a lot of good fighters and I'm going to show my heart in the ring.
"There's no pressure but I'm looking forward to an excellent performance. I'm ready to fight today if the fight was today. I feel faster at 147. I won't be flat-footed in there. You're going to see it all on Saturday.
"I feel like I'm one of the most versatile fighters in the sport. I'm going to feel strong for 12 rounds on Saturday. I've felt strong all camp."
PAULIE MALIGNAGGI
"I feel great at 147 pounds. I've always felt very strong at this weight and it's where I should be. I still had to make sacrifices in training but I've never made weight so easily. I'm coming off back-to-back camps and I feel like I'm in the best shape I've ever been.
"To be a two-time world champion you need to be able to do more than just jab and move. My IQ and my overall boxing ability and skillset make me the fighter that I am today.
"I don't think Danny is overlooking me but I feel that the fans and the media are. I love challenges and I love things that motivate me. I wake up in the morning saying this is hard, but I know I can do it.
"The bigger the challenge the more excited I am. It brings the best out of me. I have fought some of the greatest fighters of our time. There's no reason I would stop now.
"Fighting at home at Barclays Center against Danny Garcia, one of the biggest fights in boxing, I couldn't ask for more."
DANIEL JACOBS
"Sergio Mora is a slick fighter. He can slip punches well and he's defensively minded. He's a cagey fighter but he lacks power. He has a lot of defensive flaws and I just have to be patient and take advantage of them.
"We have a game plan in store, but in a pro fight anything can happen. You have to be able to adjust on the fly.
"I have a great team that helps me take care of things so that I can focus on training. I avoid all distractions that would take me away from being at my best.
"Fighting on the PBC cards has been outstanding. I love the intro and coming out on that stage. I felt like a superstar.
"This training camp has been a pleasure, hard work but a pleasure. It was difficult because Sergio is so hard to prepare for. You can't prepare for it with sparring or just one thing. I'm looking forward to showing my true skills and showing what a true champion is."
SERGIO MORA
"I'm thrilled about this opportunity. I've had two huge letdowns before with world title shots falling through. Now that this is here, there is no way I'm going to let it pass me by.
"I'm happy to be here. I'm happy to be at Barclays and happy to be on PBC. I love being the underdog and I'm going to shock the world on Saturday night.
"I'm in the second phase of my career now, DiBella and PBC have saved my career and my life.
"PBC is great, it's free TV and we're putting out heart, blood, sweat and tears into this and the fans get to see it on free TV. This is great for the fans, for the fighters and for the entire sport as a whole; it's what boxing needed."
RAFAEL VASQUEZ
"This is a great opportunity and a blessing to be on this card. There's so many great fighters from Brooklyn. Barclays Center is great and it gives us fighters from Brooklyn the opportunity to fight at a first class venue right here at home.
[On his Autistic eight-year-old daughter Kaylene]..."I want to show other people that are dealing with this, that they are not alone. I see this as a blessing to be able to raise awareness and speak out and show other families that are struggling with Autism that we are in this together.
"When people see me step into the ring I want them to know that I'm not only fighting for myself but I'm fighting for them. I want to be the face of Autism in boxing."
HEATHER HARDY
"It's really important to me that I stay relevant and that I'm a part of the conversation so when I saw this fight coming up in August I made sure that I was on this card.
"There really is extra motivation going up against Renata Domsodi again. I felt like when the two of us faced off last time and the bout was ruled a no contest that we owed it to every other female boxer to show that we belong there and I thought she quit.
"Renata was coming in with her face down swinging her arms and I charged her while she was coming in and that caused the cut. We've been working on stepping to the side when she does that and being a little bit more patient.
"If all goes well Saturday I'll be ready to get back in the ring in September. I'm in shape and I live in the gym. This is what I do. You have to stay a part of the conversation. I want to see a higher level of competition every time I step into the ring.
"This is probably the hardest I've ever worked, out of all of my camps. Not for any other reason than just putting in extra work. Honestly I'm in the best shape of my life."
TRAVIS PETERKIN
"I've trained so hard, I put blood, sweat and tears into this. I put my soul into this. I put my life into this. We're ready.
"It's no secret that I'm from Brooklyn, born and raised, I didn't move here from anywhere. Guys like Mike Tyson, Riddick Bowe and Shannon Briggs I just want to follow in their footsteps. I want to be great and learn from those that came before me.
"I'm a boxer-puncher. I'll adapt to the fighter. If he runs, I'll go get him. But I also know how to be smart and use my technical abilities.
"I'm facing a tough guy in Lenin Castillo. He's got a good record and was a 2008 Olympian. Everything looks good on paper, but when the time comes, I'm going to take him out.
"I train right here at Gleason's. When we're a couple months from a fight everybody is smiling and joking but when we're this close to the fight, everybody is serious. It's all about hard work."

Drinking Beet Juice Regularly May Lengthen Your Workouts: New Study
Newswise — Bethesda, Md.—Beet juice is a dietary source of the molecule nitrate. When converted in the body, nitrate can dilate the blood vessels and increase blood flow, both important factors for exercise performance. In a new study from American Journal of Physiology–Regulatory, Integrative and Comparative Physiology, healthy male subjects who drank beet juice for 15 days had lower blood pressure and more dilated blood vessels at rest and during exercise. Blood vessels also dilated more easily and the heart consumed less oxygen during exercise with beet juice consumption.
According to the researchers, the findings suggest that beet juice can be used as a dietary nutraceutical supplement to enhance oxygen delivery to the muscles and reduce the work the heart does during exercise. Exercise can be “performed at a given workload for a longer period of time before the onset of fatigue,” the researchers added.
The article “Effects of Chronic Dietary Nitrate Supplementation on the Hemodynamic Response to Dynamic Exercise” is published ahead of print in the American Journal of Physiology–Regulatory, Integrative and Comparative Physiology.

Dietary protein recommendations need updating: experts
It’s not only how much protein you eat, it’s the type of protein that is important.
Most protein-rich foods are also rich in vitamins and minerals. Choosing the right type of protein, within the bounds of Canada’s Food Guide, will lead to an overall healthy diet. This new research suggests that including a moderate amount of high-quality protein at each meal may offer an effective strategy for optimising muscle protein synthesis and potentially protecting muscle mass. “The message of protein at each meal in moderation is a paradigm shift from the typical nonspecific default recommendation of a large, global increase in protein intake for populations actively seeking to increase or maintain muscle mass and function” says co-author of the study, Dr. Rajavel Elango, Scientist at the Child & Family Research Institute at BC Children’s Hospital and Assistant Professor, Department of Pediatrics, School of Population and Public Health, University of British Columbia. “It is important that individuals and policy makers alike are aware of the advances in dietary protein research technology that aid in making healthy dietary choices”.
New research based on modern techniques suggests updates to recommendations may be needed.
Recommendations for protein intake in healthy populations are based on older techniques. Current dietary protein recommendations may not be sufficient to promote optimal muscle health in all populations, especially aging populations, which are prone to muscle loss. The research published today in Applied Physiology, Nutrition, and Metabolism provides an overview of recent developments in research that are aimed at defining protein requirements.
Protein continues to be the right choice for weight loss management.
Promoting healthy protein choices combined with physical activity is an essential approach as policy makers attempt to control the obesity epidemic. In weight loss management, adequate protein (while ensuring that caloric intake is within a healthy range) has been shown to preserve muscle mass without gain in fat mass.
Findings of this study are particularly important as they apply across the life-cycle; this is reinforced as protein is needed to make new tissues during periods of growth and development.

Abstract
Post-exercise hypotension (PEH), calculated by the difference between post and pre-exercise values, it is greater after exercise performed in the evening than the morning.
However, the hypotensive effect of morning exercise may be masked by the morning circadian increase in blood pressure.
This study investigated PEH and its hemodynamic and autonomic mechanisms after sessions of aerobic exercise performed in the morning and evening, controlling for responses observed after control sessions performed at the same times of day.
Sixteen pre-hypertensive men underwent four sessions (random order): two conducted in the morning (7:30am) and two in the evening (5pm).
At each time of day, subjects underwent an exercise (cycling, 45 min, 50%VO2peak) and a control (sitting rest) session.
Measurements were taken pre- and post-interventions in all the sessions.
The net effects of exercise were calculated for each time of day by [(post-pre exercise)-(post-pre control)] and were compared by paired t-test (P<0.05). Exercise hypotensive net effects (e.g., decreasing systolic, diastolic and mean blood pressure) occurred at both times of day, but systolic blood pressure reductions were greater after morning exercise (-7±3 vs. -3±4 mmHg, P<0.05).
Exercise decreased cardiac output only in the morning (-460±771 ml/min, P<0.05), while it decreased stroke volume similarly at both times of day and increased heart rate less in the morning than in the evening (+7±5 vs. +10±5 bpm, P<0.05).
Only evening exercise increased sympathovagal balance (+1.5±1.6, P<0.05) and calf blood flow responses to reactive hyperemia (+120±179 vs. -70±188 U, P<0.05).
In conclusion, PEH occurs after exercise conducted at both times of day, but the systolic hypotensive effect is greater after morning exercise when circadian variations are considered.
This greater effect is accompanied by a reduction of cardiac output due to a smaller increase in heart rate and cardiac sympathovagal balance.

Abstract
An improved understanding of how weight-loss interventions might be tailored to improve emotional eating is required.
This study aimed to assess mediation of the relationship between increased exercise and decreased emotional eating so that behavioral treatments might be optimized.
After randomization, women with obesity (N=108; mean age =48 years) were assigned to either a previously tested treatment of manual-based self-help for nutrition and exercise plus brief phone follow-ups, or a new protocol of cognitive-behavioral methods of exercise support intended to carry-over psychological improvements to better controlled eating and weight loss.
A community-based field setting was incorporated.
Validated self-report measures were administered over 6 months.
Significant overall improvements in exercise outputs, emotional eating, mood, and self-regulation and self-efficacy for controlled eating were found.
The newly developed treatment protocol demonstrated significantly greater improvements in exercise outputs and self-regulation.
In a multiple mediation analysis, changes in self-regulation, self-efficacy, and mood significantly mediated the relationship between changes in exercise and emotional eating.
Changes in self-efficacy and mood were significant independent mediators.
Within follow-up analyses, the substitution of emotional eating subscales that addressed specific moods, and a subscale of self-efficacy for controlled eating that addressed that factor specifically in the presence of negative emotions, yielded results generally consistent with those of the multiple mediation analysis.
Results suggested a psychological pathway of exercise’s association with emotional eating changes in women with obesity. Guided by the present findings, tailoring exercise support and leveraging it to induce specific psychological improvements might reduce emotional eating and improve weight-management outcomes.

Abstract
Pre-exercise nutritional practices for active females exercising for mood, cognitive and appetite benefits are not well established.
Results from an initial field pilot study showed that higher energy intake at breakfast was associated with lower fatigue and higher overall mood and alertness post-exercise (all p < 0.05).
In a follow-up, randomised, controlled trial, 24 active women completed three trials in a balanced, cross-over design. At 0815 h participants completed baseline cognitive tasks, mood and appetite visual analogue scales (VAS) and were administered a cereal breakfast (providing 118 or 236 kcal) or no breakfast.
After 45 min, they completed a 30 min run at 65% heart rate reserve (HRR). Parameters were re-assessed immediately after exercise, then hourly until lunch (~1240 h), immediately post-lunch and at 1500 and 1900 h via a mobile phone. Breakfast enhanced feelings of relaxation before lunch (p < 0.05, d > 0.40), though breakfast was detrimental for working memory mid-afternoon (p = 0.019, d = 0.37) and mental fatigue and tension later in the day (all p < 0.05, d > 0.038).
Breakfast was also beneficial for appetite control before lunch irrespective of size (all p < 0.05, d > 0.43).
These data provide information on pre-exercise nutritional practices for active females and suggest that a small breakfast eaten prior to exercise can benefit post-exercise mood and subjective appetite ratings.

Abstract
Fat oxidation has been shown to increase after short term green tea extract (GTE) ingestion and after one bout of intermittent sprinting exercise (ISE). Whether combining the two will result in greater fat oxidation after ISE is undetermined.
The aim of the current study was to investigate the combined effect of short term GTE and a single session of ISE upon post-exercise fat oxidation.
Fourteen women consumed three GTE or placebo capsules the day before and one capsule 90 min before a 20-min ISE cycling protocol followed by 1 h of resting recovery. Fat oxidation was calculated using indirect calorimetry.
There was a significant increase in fat oxidation post-exercise compared to at rest in the placebo condition (p < 0.01). After GTE ingestion, however, at rest and post-exercise, fat oxidation was significantly greater (p < 0.05) than that after placebo.
Plasma glycerol levels at rest and 15 min during post-exercise were significantly higher (p < 0.05) after GTE consumption compared to placebo. Compared to placebo, plasma catecholamines increased significantly after GTE consumption and 20 min after ISE (p < 0.05).
Acute GTE ingestion significantly increased fat oxidation under resting and post-exercise conditions when compared to placebo.

For kids with injured ankles, less treatment may be more: American College of Emergency Physicians
“Currently, x-rays are ordered for up to 95 percent of children who come to emergency departments with ankle injuries, though only 12 percent of those x-rays show fractures,” said lead study author Kathy Boutis, MD, MSc, of The Hospital for Sick Children and the University of Toronto in Toronto, Canada. “Widespread implementation of the LRAR could lead to a safe reduction of x-rays in children with ankle injuries, reducing unnecessary radiation exposure and health care costs.”
Researchers compared children with ankle injuries at emergency departments that did and did not use the LRAR. At emergency departments using the LRAR to assess children with acute ankle injuries, there were 22.9 percent fewer ankle x-rays and health care costs were $36.93 less compared with those that did not use the rule. Importantly, in reducing x-rays, there were no significant differences in the frequency of missed clinically important fractures or in use of health care resources after a patient was discharged from the emergency department.
“Our findings are good news for the two million American and Canadian children with hurt ankles who visit emergency departments each year: although most currently receive x-rays, many do not actually need them,” said Dr. Boutis. “There are also potential cost savings. In a publicly funded health care system, using the LRAR to decide if x-rays are necessary in children with ankle injuries modestly reduced health system costs without increasing patient costs. In a privately funded health care system like the one in the Unites States, the cost savings would likely be realized by the patient or insurer.”

Most chronic pain patients use alternative therapies, but many don’t tell their doctors
Researchers surveyed more than 6,000 patients in Oregon and Washington who were Kaiser Permanente members from 2009 – 2011 and had three or more outpatient visits for chronic pain within 18 months. They found that 58 percent of these patients had used chiropractic care or acupuncture or both.
The majority of patients shared information about these alternative therapies with their primary care provider, however a good portion (35 percent of patients who had acupuncture only, and 42 percent of patients who had chiropractic care only) didn’t talk to their providers about this care. Almost all of these patients said they would be happy to share this information if their provider asked.
“Our study confirms that most of our patients with chronic pain are seeking complementary treatments to supplement the care we provide in the primary care setting,” said Charles Elder, MD, MPH, lead author of the study and affiliate investigator at the Kaiser Permanente Center for Health Research. “The problem is that too often, doctors don’t ask about this treatment, and patients don’t volunteer the information.”
Chronic pain affects approximately 100 million Americans each year and costs nearly $600 billion, according to report from the Institute of Medicine.
Dr. Elder, who is also the physician lead for Kaiser Permanente’s complementary and alternative medicine program, added, “We want our patients to get better, so we need to ask them about the alternative and complementary approaches they are using. If we know what’s working and what’s not working, we can do a better job advising patients, and we may be able to recommend an approach they haven’t tried.”
To find out how patients accessed this care researchers examined the medical records of patients who received acupuncture or chiropractic care in 2011. The majority of patients (66 percent) who received acupuncture accessed the services through their health plan, using a clinician referral or self-referral benefit. About half (45 percent) of patients who received chiropractic care accessed that care through their health plan. The remainder of patients went outside the health plan to access these services, or used a combination of health plan and outside resources to access the services.
The majority of the patients in the study (71 percent) were women, and the mean age was 61. Common complaints included back pain, joint pain, arthritis, extremity, neck and muscle pain, and headache.
Patients completed the survey online or by mail. It included 17 questions about the type of pain patients experienced, and their use of acupuncture, chiropractic care, and other alternative and complementary therapies. This survey was administered as part of a study called RELIEF, which is comparing outcomes among chronic pain patients who receive chiropractic care and acupuncture, and those who don’t.
